Introduction to the Ashwagandha Supplement
Pelank Supplement ©
🌿 Ashwagandha is a potent medicinal herb from the Solanaceae family, whose scientific name is Withania somnifera. This plant is also known in scientific texts by other names such as Indian Ginseng and Winter Cherry, but the most authoritative and correct name is Ashwagandha.
📜 The history of this herb dates back over 3,000 years to Ayurvedic medicine, where it was used to boost vital energy (Prana), strengthen the mind, reduce stress, and improve sleep. In Ayurveda, Ashwagandha is considered one of the “Rasayanas”—compounds that help restore youth and increase longevity.
⚡ Ashwagandha is a true Adaptogen; meaning it can make the body more resilient against physical, mental, and environmental stresses. Adaptogens are substances that help bring the function of the nervous, hormonal, and immune systems closer to a state of balance (Homeostasis).
🌍 The reasons for Ashwagandha’s global popularity in the last decade are very extensive:
🧪 Strong scientific backing in reducing cortisol and managing stress
😴 Improved sleep and relaxation
🧠 Boosting focus, memory, and cognitive function
💪 Increased strength, muscle, and improved athletic performance
🔝 Explosive growth in the U.S. supplement market due to increased societal need for calm, quality sleep, and sustained energy
✨ Today, Ashwagandha is recognized not only in Europe and America but across the globe as one of the most researched and popular supplements. A compound that targets the balance of mind and body.
Botanical Characteristics
Botanical Profile
🌱 Ashwagandha, scientifically named Withania somnifera, is a medicinal plant belonging to the Solanaceae family; the same family that includes potatoes, tomatoes, and eggplant. This plant is native to the dry regions of India, Nepal, Pakistan, and parts of the Middle East, and thrives well in warm, poor soils.
🌿 The plant structure is short and woody, typically reaching a height of 30 to 60 centimeters. The leaves are oval and velvety, and its fruit is a small, orange-red seed similar to physalis berries.
🪵 The most important part of this plant used is its root; this is where the highest concentration of active compounds (Withanolides) is located. However, the leaves also contain beneficial alkaloids and saponins, but the world’s most standardized commercial extracts (like KSM-66) are specifically derived from the pure root.
⚗️ Main Active Compounds of Ashwagandha
⚗️ The main active compounds of Ashwagandha include the following:
🔸 Withanolides – The most important class of compounds with anti-inflammatory, anti-stress, and adaptogenic effects
🔸 Alkaloids – Affective on the nervous system and relaxation
🔸 Saponins – Immune response boosters and antioxidants
🔸 Withaferin A – The most potent biological compound, with potential anti-inflammatory and anti-cancer effects
🌾 Difference in Function Between Root and Leaf
🟤 Root → Contains stable and balanced amount of Withanolides, suitable for reducing stress, improving sleep, and enhancing athletic performance.
🟢 Leaf → Richer in Withaferin A; a compound that has stronger effects but is not suitable for long-term consumption and is generally less used in standardized supplements.
✨ This is why virtually all reputable brands worldwide—KSM-66, Sensoril, and Shoden—use root extract to ensure both consistent efficacy and greater safety for long-term consumption.
Biopharmacology and Absorption
🧬 After oral consumption, Ashwagandha is absorbed through the small intestine, and its active compounds—especially the Withanolides—enter the bloodstream via lipophilic pathways. Due to the fat-loving nature of these compounds, their absorption is slightly enhanced in the presence of healthy fatty foods.
⏱️ The half-life of Ashwagandha’s active compounds is estimated to be between 6 and 8 hours; for this reason, many experts suggest taking one to two doses per day to maintain relatively stable blood levels. For athletic use (pre-workout), the effects of stress reduction and strength improvement peak 3–4 hours after consumption.
⚗️ Differences in Absorption and Efficacy of Extracts
⚗️ The difference in absorption and efficacy among extracts is very important, and this is the main reason for the differences between various brands. For example:
🌿 KSM-66 → A full-spectrum extract from the root; a perfect balance of Withanolides, with slower but more stable absorption.
🌱 Sensoril → A standardized and stronger extract from the root + leaf; faster absorption but sometimes with a greater sedative effect.
🍃 Shoden → Contains highly concentrated Withanolides; the highest bioavailability at low doses.
📈 Studies show that standardized extracts (such as KSM-66 and Sensoril) have up to 3 times higher bioavailability compared to regular powdered extracts. This means that a smaller amount of the supplement yields greater effects.
🧪 Absorption Enhancers
Unlike many medicinal herbs, there is insufficient evidence for the effect of black pepper (piperine) on increasing the absorption of Ashwagandha. Most studies show that piperine affects compounds like curcumin, but its effect on Withanolides is minimal or unclear. Therefore, adding piperine to the formula is more of a marketing move than a scientific one.
🔬 Why do KSM-66 and Sensoril have different absorption profiles?
The main reasons for the difference in absorption between these two extracts can be summarized as follows:
🧬 Different withanolide structures → Sensoril contains a higher amount of Withaferin A.
🪵 Plant part used → KSM-66 uses only the root; Sensoril uses both root + leaf.
⚗️ Extraction method → KSM-66 uses a “Green Extraction” technique without alcohol, preserving the natural balance of compounds.
💧 Solvents and separation processes → These affect particle size, solubility, and absorption rate.
✨ Conclusion:
KSM-66 → Stable absorption, suitable for long-term use, with mild and balanced effects.
Sensoril → Faster absorption, stronger calming and anti-stress effects, suitable for shorter-term use.
Mechanism of Action of Ashwagandha
Mechanisms of Action
🧠 HPA Axis Modulation
Ashwagandha influences the Hypothalamus–Pituitary–Adrenal (HPA) axis, the body’s primary stress-management system, helping regulate hormonal balance. This mechanism reduces the body’s reactivity to stress and promotes a faster return to a state of calm.
⬇️ Cortisol Reduction
One of the most important effects of ashwagandha is a significant reduction in cortisol levels. Studies have shown that standardized ashwagandha extracts can reduce cortisol by up to 30%, leading to reduced anxiety, improved sleep quality, sustained energy levels, and prevention of muscle breakdown.
🔥 Anti-inflammatory and Antioxidant Effects
Withanolides exhibit strong anti-inflammatory activity. These compounds help reduce systemic inflammation, improve recovery, and protect cells by lowering inflammatory cytokines and increasing the body’s natural antioxidants (such as SOD and catalase).
🧬 Effects on the GABA and Serotonin Systems
Evidence suggests that ashwagandha may increase GABA receptor activity and enhance serotonin synthesis or pathway sensitivity. These mechanisms support its calming, anti-anxiety, and mood-enhancing effects—without causing dependence.
💆 Improved Stress Response
Ashwagandha’s active compounds increase stress resilience, meaning the body’s ability to cope with and recover from physical and psychological stress. This effect is especially noticeable in athletes, busy individuals, and those experiencing inadequate sleep.
🦋 Effects on Thyroid Function
Thyroid Function Support
Limited studies suggest that ashwagandha may cause a mild increase in T3 and T4 levels and a reduction in TSH—particularly in individuals with mild (subclinical) hypothyroidism.
✔ However, this effect is not beneficial for everyone and is not recommended for individuals with overt hyperthyroidism.

Potential and Emerging Benefits
1️⃣ Potential Anti-Cancer Effects
🧪 What do we know?
🧬 In in vitro (cell-based laboratory) studies and in vivo animal studies, compounds such as Withaferin A and Withanolide D have shown the ability to:
✔️ Halt the cell cycle of cancer cells
✔️ Trigger apoptosis (programmed cancer cell death)
✔️ Reduce tumor spread and metastasis
🔗 Examples of laboratory references:
Study on Withaferin A and inhibition of NF-κB and STAT3 pathways in cancer cells:
https://pubmed.ncbi.nlm.nih.gov/16595650
Comprehensive review on the anti-cancer potential of withanolides:
https://pubmed.ncbi.nlm.nih.gov/19692202
⚠️ Important note:
This evidence is primarily based on cell and animal studies; there are currently no strong clinical trials in humans supporting cancer treatment. Therefore, ashwagandha should never replace standard cancer therapies and is only considered a promising area of future research.
2️⃣ Neurogenesis and Neural Cell Growth
🧪 Some animal studies suggest that ashwagandha may:
✔️ Stimulate neurite outgrowth (neuronal branching)
✔️ Prevent neuronal degeneration
🔗 Example:
Study on neurite outgrowth and neuroprotection with Withanolide A in animal models:
https://pubmed.ncbi.nlm.nih.gov/14669250
✨ Potential conclusion: These mechanisms may help explain improvements in memory, focus, and protection of the brain against stress and aging; however, more clinical data in humans are needed before making definitive claims.
3️⃣ Neuroprotection
🧬 In animal models of Alzheimer’s and Parkinson’s disease, ashwagandha has been shown to:
✔️ Reduce oxidative stress in the brain
✔️ Limit the accumulation of toxic proteins (such as β-amyloid)
✔️ Improve cognitive function in animals
🔗 Example references:
Neuroprotective effects of ashwagandha in Alzheimer’s disease models:
https://pubmed.ncbi.nlm.nih.gov/21496408
Review of the neuroprotective potential of Withania somnifera:
https://pubmed.ncbi.nlm.nih.gov/25263125
⚠️ Emphasis again: These findings are promising but do not yet mean “treatment of Alzheimer’s or Parkinson’s disease in humans”; for now, they should be viewed as an emerging research area.
4️⃣ Anti-Aging and Cellular Health
💡 Due to a combination of effects:
✔️ Antioxidant activity
✔️ Anti-inflammatory effects
✔️ Reduced stress and cortisol levels
Some researchers consider ashwagandha a potential candidate for slowing certain aspects of the cellular aging process.
In animal studies, ashwagandha supplementation has been associated with:
✔️ Reduced oxidative markers
✔️ Improved endogenous antioxidant status (such as SOD and catalase)
These effects have been observed.
🔗 Related review:
https://pubmed.ncbi.nlm.nih.gov/23560637
👀 However, no long-term human studies are currently available showing that it directly increases lifespan or slows aging. For now, it can be stated that:
“Ashwagandha likely supports cellular health and youthfulness indirectly by reducing stress and inflammation.”
5️⃣ Effects on Social Anxiety
🧪 Data on social anxiety are still limited and inconsistent, but:
Some trials suggest that ashwagandha may improve overall anxiety and social functioning;
In individuals with occupational or academic stress, reductions in general stress may indirectly decrease fear of social situations.
🔗 Example of a study on stress and overall well-being that also reported improvements in social relationships:
https://pubmed.ncbi.nlm.nih.gov/31517876
✅ Summary:
Direct evidence on “Social Anxiety Disorder” is limited;
However, through stress reduction and mood improvement, it may help reduce social anxiety in some individuals; it should not replace psychotherapy or medication in severe cases.
6️⃣ Thyroid Effects
🧾 Limited but important human studies:
In a clinical trial involving individuals with subclinical hypothyroidism, 8 weeks of ashwagandha supplementation led to:
✔️ Increased T3 and T4 levels
✔️ Reduced TSH
Compared to the placebo group.
🔗 Sample study:
https://pubmed.ncbi.nlm.nih.gov/28829155
✨ Conclusion:
In individuals with mild hypothyroidism, it may help improve thyroid function.
However, in those with hyperthyroidism or active autoimmune thyroid disease (such as Graves’ disease), this stimulation may be problematic.
⚠️ Therefore:
For individuals with thyroid disorders, consulting a physician before using ashwagandha is essential;
Ashwagandha cannot replace thyroid medications, but in certain situations, it may serve as an adjunct therapy.
🧷 Summary of Emerging Benefits
✅ Promising evidence in the following areas:
✔️ Anti-cancer effects in laboratory models
✔️ Neurogenesis and neuroprotection
✔️ Thyroid support in mild hypothyroidism
✔️ General stress reduction that may indirectly improve social anxiety
⚠️ However, for all of these areas, it is important to note that:
❌ Large, long-term human clinical trials are still limited
❌ These effects should not replace standard treatments (for cancer, thyroid disorders, or neurological diseases)
Types of Ashwagandha Supplements
Supplement Forms

🔄 Should ashwagandha be cycled or taken continuously?
Cycling vs Continuous Use
Continuous Use
Most scientific studies have evaluated ashwagandha when taken daily and continuously for 6 to 12 weeks.
Conclusion:
✔️ Stable and cumulative effects
✔️ Good tolerability
✔️ No evidence of tolerance or dependence
Cycled Use
Some experts recommend:
✅ 8 weeks of use → 2 weeks off
✔️ This recommendation is based mainly on user experience rather than strict scientific necessity.
📌 Therefore:
✅ If you have a specific therapeutic goal (stress, focus, sleep), continuous use for 8–12 weeks is the best option.
✅ If using ashwagandha for longer than 3 months, it is advisable to include a 10–14 day break every few months to help maintain hormonal balance and reduce the risk of tolerance.

Ashwagandha Drug Interactions
Drug Interactions
⚠️ Important note: This section does not replace medical advice; anyone taking medications should consult a physician or pharmacist before starting ashwagandha.
🦋 Thyroid Medications
🧾 Ashwagandha may slightly increase T3 and T4 levels and reduce TSH in some individuals.
💊 If you are taking levothyroxine or other thyroid medications:
⚠️ The medication’s effect may become stronger, potentially pushing you into a hyperthyroid range.
🩺 TSH and T3/T4 levels should be monitored under medical supervision.
🚫 Generally not recommended for individuals with uncontrolled hyperthyroidism or Graves’ disease.
😴 Benzodiazepines and Sedatives
Such as: diazepam, alprazolam, clonazepam, lorazepam, zolpidem, zopiclone, etc.
😴 Ashwagandha itself has mild sedative effects;
When combined with these medications:
⚠️ Drowsiness, mental fog, and reduced concentration may increase.
🚗 The risk during driving and operating machinery is higher.
📌 If taken together, the ashwagandha dose should be low and must be discussed with a physician.
🙂 Antidepressants
Classes:
SSRIs → such as sertraline, fluoxetine, citalopram
SNRIs → such as duloxetine, venlafaxine
TCAs and others
🧠 Ashwagandha affects GABA and serotonin pathways; theoretically:
It may slightly enhance the sedative or anxiolytic effects of these medications.
⚠️ At high doses combined with multiple psychiatric medications, the risk of drowsiness, confusion, and—at least theoretically—serotonin syndrome may increase (there is no strong clinical evidence, but caution is important).
✅ General rule:
If you are taking one antidepressant → use a moderate dose of ashwagandha under medical supervision.
If you are taking multiple psychiatric medications simultaneously → it is better to avoid ashwagandha unless approved by a psychiatrist.
🦠 Immunotherapy and Autoimmune Medications
Example :
Immunosuppressive drugs (high-dose corticosteroids, methotrexate, cyclosporine, tacrolimus, biologics such as infliximab, etc.)
Medications for autoimmune diseases (RA, MS, lupus, etc.)
🌿 Ashwagandha has shown mild immune-stimulating effects in some studies.
⚠️ Therefore:
In individuals receiving immunotherapy, it could theoretically interfere with the drug’s intended effect (immune suppression).
In some autoimmune diseases, there is a theoretical risk of disease exacerbation (definitive evidence is limited, but caution is warranted).
🚫 Practical recommendation:
If you are using immunosuppressive medications → do not use ashwagandha unless your physician approves it.
🍬 Diabetes Medications
Antidiabetic Drugs
Such as: metformin, glibenclamide, insulin, etc.
🧪 Some small studies suggest that ashwagandha may slightly lower blood glucose levels.
⚠️ When combined with blood sugar–lowering medications:
The risk of hypoglycemia (low blood sugar) may increase slightly, especially if you are also following a strict diet or engaging in intense exercise.
Blood glucose should be monitored regularly, and symptoms such as dizziness, cold sweats, and tremors should be taken seriously.
✅ Solution:
Start with a low dose of ashwagandha
Inform your diabetes physician so medication doses can be adjusted if necessary
🩺 Blood Pressure Medications
Antihypertensives
Example : Losartan, enalapril, amlodipine, bisoprolol, etc.
🌿 Due to its calming and stress-reducing effects, ashwagandha may slightly lower blood pressure in some individuals.
⚠️ When combined with blood pressure medications, especially beta-blockers and potent antihypertensives:
Risk of hypotension (low blood pressure):
Dizziness
Blackout sensation when standing up
Weakness
✅ Recommendation:
Start with a low dose
Monitor blood pressure during the first few days
If a significant drop occurs, discontinue ashwagandha and contact a physician
✨ Quick Guide to Drug Interactions
Drug category | Type of interaction | Recommendation |
|---|---|---|
Thyroid | Increased drug effect, risk of hyperthyroidism | Strict medical supervision, laboratory monitoring required |
Benzodiazepines / Sedatives | Increased drowsiness | Use with caution, avoid driving |
Antidepressants | Enhanced sedative effect, theoretical serotonin risk | Moderate dosing, coordinate with a psychiatrist |
Immunotherapy / Autoimmune | Potential interference with immune suppression | Generally not recommended |
Diabetes | Risk of hypoglycemia | Regular glucose monitoring, low dose |
Blood pressure | Risk of hypotension | Monitor blood pressure, low dose |

Common Myths About Ashwagandha
Myths & Misconceptions
❌ Is ashwagandha a steroid?
💊 No, absolutely not!
Ashwagandha is a medicinal herb, not an anabolic steroid.
🌿 Its active compounds are withanolides, which have anti-inflammatory and anti-stress effects—they have no similarity to testosterone or steroid drugs.
📌 This myth likely exists because some studies show a mild increase in testosterone with ashwagandha; however, these changes are natural and limited, not steroid-like.
❌ Is ashwagandha addictive?
Strength Gains
🧠 No. There is no evidence of addiction or dependence.
Unlike sedative medications such as benzodiazepines, ashwagandha:
Does not overstimulate or saturate receptors
Has stable, non-progressive tolerance
Does not cause withdrawal symptoms when discontinued
📌 It can be discontinued at any time without difficulty.
❌ Is ashwagandha safe for everyone?
⚠️ No.
Although ashwagandha is safe for most people, it is not suitable for certain groups:
🚫 Pregnant women
🚫 Individuals with hyperthyroidism
🚫 Patients with autoimmune diseases (MS, RA, lupus)
🚫 Individuals using sedative medications
🚫 People with liver disorders
📌 Therefore, “safe for everyone” is a completely false belief.
❌ Does ashwagandha always cause drowsiness?
😴 No, that’s not the case.
The effects of ashwagandha depend on the extract type, timing of use, and dosage.
🔹 Sensoril → more sedating
🔹 KSM-66 → more balanced and better suited for daytime use
🔹 Shoden → potent, but does not always cause drowsiness
📌 Some people use it to improve focus and energy during the day.
❌ Does ashwagandha always increase testosterone?
🧪 No. This is a common misconception.
Increases in testosterone are only observed under the following conditions:
✔ Men with high stress levels
✔ Individuals with low–normal testosterone levels
✔ Use of 600 mg/day for at least 8–12 weeks
✔ Combined with adequate sleep and regular training
❌ If testosterone levels are already normal and healthy, no significant change usually occurs.
❌ In women, no undesirable hormonal increases have been reported.
✨ Quick Guide to Common Myths
Myth | Reality |
|---|---|
“Ashwagandha is a steroid” | ❌ A medicinal herb → no similarity to steroids |
“Addictive” | ❌ Does not cause dependence |
Safe for everyone | ❌ Some groups should not use it |
Always causes drowsiness | ❌ It depends on the extract type and dose |
Always increases testosterone | ❌ It only affects certain individuals |
How to Choose a High-Quality Supplement
Choosing a Quality Ashwagandha Supplement
Choosing the wrong ashwagandha supplement =
❌ Weak effectiveness
❌ Higher risk of side effects
❌ Money wasted
Choosing the right one =
✅ Maximum effectiveness
✅ High safety
✅ Real, evidence-based results
Let’s break down the best choice step by step:
🧪 Withanolide Percentage
The Most Important Selection Criterion
🌿 Withanolides are the main active compounds in ashwagandha.
The more precisely defined and consistent their percentage, the more reliable the supplement.
📌 Standard ranges:
5% → Balanced, suitable for daily use (KSM-66)
10–12% → More potent, more calming effects (Sensoril)
20–35% → Very potent, lower dosing, suitable for high-potency formulas (Shoden)
⚠️ Be careful:
Some low-quality brands report higher percentages using UV methods, which are not accurate.
True measurement should be done using HPLC.
⚗️ Extract Standardization
🔍 The following should be clearly stated on the label:
✔ Standardized Extract
✔ Clearly specified withanolide percentage
✔ Standardization method: HPLC
Why is this important?
Plain ashwagandha powder contains highly variable levels of active compounds.
Standardized extracts provide consistent and predictable effects.
Nearly all high-quality studies have been conducted using standardized extracts.
If the label only states:
❌ “Ashwagandha Root Powder”
Be aware that the effectiveness is significantly lower.
🧯 Heavy Metals Testing
⚠️ Medicinal plants like ashwagandha can absorb heavy metals:
Lead (Pb)
Arsenic (As)
Mercury (Hg)
Cadmium (Cd)
For this reason, the brand should provide the following:
✔ Certified heavy metal testing
✔ A visible COA (Certificate of Analysis)
✔ Independent third-party laboratory testing
📌 Professional brands usually publish their COA on their website.
🧾 Brand Transparency
A reputable brand should:
🔎 Clearly state the source of the plant
India? USA? Organic farms?
📄 Explain the extraction process
Alcohol-free?
Green extraction?
Water-based?
🧪 Publish quality testing results
COA
Heavy Metals
Microbial Testing
🛡️ Certifications:
USDA Organic
Non-GMO
GMP Certified
Gluten-Free
ISO Lab Tested
The greater the brand transparency → the higher the scientific trust.

Frequently Asked Questions
FAQ
💬 Yes. Most human studies have examined daily use for 6–12 weeks, and no issues have been reported in healthy individuals. However, for longer-term use (several consecutive months), it’s better to take a 10–14 day break every 2–3 months. If you are taking medications, consult your physician.
💬 It does not directly cause weight gain or weight loss. However, by reducing stress and improving sleep, it may help regulate appetite and hormones. In some people, appetite may increase slightly, while in others it may decrease. There is still no strong evidence supporting its use for weight loss.
💬 It is absolutely suitable for women as well—especially for stress, anxiety, sleep, and fatigue. No increase in testosterone has been reported in women, and there are no major hormonal concerns. It is simply not recommended during pregnancy or breastfeeding.
💬 There is no strong direct evidence. Indirectly, by reducing stress and balancing hormones, it may help improve hair health in some individuals, but it should not be considered a treatment for hair loss.
💬 Yes. Many people in the U.S. take ashwagandha with their morning coffee. Ashwagandha may help blunt caffeine-related stress and palpitations. If your caffeine intake is very high or you are prone to anxiety, start with a lower dose first.
💬 Yes. In healthy individuals, no interactions have been observed with multivitamins, whey protein, creatine, or most sports supplements. Just be mindful if your pre-workout formula contains strong stimulants—keep dosages reasonable.
💬 There is no clear evidence of a direct interaction with oral contraceptives. However, since ashwagandha can influence hormones and liver metabolism, if you are using birth control pills, it’s best to consult your physician or gynecologist before long-term use.
💬 It can be helpful for mild to moderate anxiety and everyday stress. However, in severe conditions such as panic disorder or severe generalized anxiety, ashwagandha is not a replacement for psychiatric treatment or psychotherapy and should only be used as a supportive aid.
💬 Some individuals report improved focus, and limited studies suggest cognitive benefits. However, evidence for treating ADHD is still weak. If you are taking ADHD medications (such as methylphenidate/Ritalin), you should coordinate with your physician.
💬 If depression is mild and well-controlled, some physicians in the U.S. consider ashwagandha as a supportive supplement for stress and sleep. However, in moderate to severe depression—especially when strong medications are involved—do not start it on your own; consult a psychiatrist first.
💬 Nothing serious happens; you may simply notice less effect that day. Resume your normal routine the next day and do not double the dose.
💬 Most studies focus on 8–12 week periods, but overall safety data suggest that at standard doses it is well tolerated in most healthy individuals. For very long-term use, it is best to:
- Take a 10–14 day break every 2–3 months
- Have blood tests once a year and check thyroid and liver function, especially if you use other supplements as well.
💬 Almost all studies have been conducted in adults over 18 years old. Use in adolescents requires direct medical supervision. For those under 18, it’s better to focus on sleep, nutrition, and non-supplement stress management strategies.
