Ashwagandha (Withania somnifera) is a herb whose popularity has grown exponentially in the Western world over the past 10 years. From traditional Ayurvedic medicine, it has become one of the most widely sold adaptogens in the world. But what is it really? How does it differ from other adaptogens? What do we truly know from scientific research, and what is just marketing? In this educational article — an honest look. This article is informational and does not replace a medical consultation.
What ashwagandha is
Ashwagandha (Sanskrit for "smell of horse" — because of the specific smell of the roots) is a small shrub that grows naturally in India, the Middle East and parts of Africa. The plant:
- Scientific name: Withania somnifera
- Family: Solanaceae (like tomatoes, aubergines)
- Traditional name: Indian ginseng, winter cherry
- Part used: most often the root, sometimes the leaves and berries
Traditional Ayurvedic medicine has used it for over 3,000 years. It is classified as a "rasayana" — a group of plants traditionally seen as supporting overall vitality.
Traditional use in Ayurveda
Ancient Ayurvedic texts (Charaka Samhita, Sushruta Samhita) describe ashwagandha as being used in various situations:
- To support the body's energy
- In situations of stress and anxiety
- For recovery after illness
- To support older age
- To support male vitality
- To support sleep quality
- To support overall vitality
In traditional use — prepared as a powder mixed with milk, honey or ghee. Today the more common form is capsules with a standardised extract.
Scientific research — what is actually known
For the sake of honesty: ashwagandha is one of the better-studied adaptogens, but most studies are small (50–100 participants) and need bigger, higher-quality studies to confirm. Here is what is currently known:
Stress and cortisol
Several randomised clinical trials suggest that ashwagandha may help maintain normal cortisol levels in stressful situations. A typical study: 8–12 weeks, 300–600 mg of standardised root extract per day.
Anxiety
Systematic reviews suggest that ashwagandha may have an anxiety-reducing effect on symptoms. The effects, however, are moderate, and it cannot replace psychotherapy or pharmacological treatment when those are needed.
Sleep quality
Several studies suggest a possible effect on sleep quality. One important study from India (2020) showed a significant improvement in sleep quality after 8 weeks. More on sleep quality — in our article on sleep quality.
Athletic performance
There are several studies on ashwagandha's effect on muscle growth and athletic performance. The results are promising, but the studies are still small.
Male testosterone
Several studies suggest a possible effect of ashwagandha on testosterone levels in men with low levels. In healthy men — the effect is smaller. More on men's energy — in our article on men's energy.
What scientific research CANNOT confirm
Honestly, what ashwagandha CANNOT do:
- "Cure" depression or clinical anxiety
- Replace antidepressants or anti-anxiety medication
- Replace lifestyle (sleep, nutrition, physical activity)
- Work in a few days — most effects are seen after 4–12 weeks
- Work the same way for everyone — the response is very individual
Different forms of ashwagandha
Various forms can be found on the market — it is important to understand the differences:
| Form | Characteristics | Typical dose |
|---|---|---|
| Root powder | Traditional form | 3–6 g/d |
| Standardised root extract | Concentrated, with a known withanolide content | 300–600 mg/d |
| KSM-66 | A patented extract, the most studied | 300–600 mg/d |
| Sensoril | Another patented extract | 125–250 mg/d |
| Leaf extract | Less studied | Varies |
Standardised extracts — for most people the most practical, since they have a consistent concentration.
How to recognise a quality product
The market is full of ashwagandha products — not all are equal:
Good signs
- A standardised withanolide percentage (usually 2.5–5%)
- Root extract (not leaf — leaf extract is less studied for safety)
- A patented form (KSM-66, Sensoril) — has a broader research base
- Third-party testing (quality, heavy metals)
- A clear country of origin
- A GMP-certified manufacturer
Warning signs
- No reference to standardisation
- Too low a price (a quality product costs €15–30 per monthly dose)
- Lofty promises ("cures anxiety in a week")
- No country-of-origin information
- No manufacturer information
Safety and side effects
Ashwagandha is considered relatively safe for most healthy adults when used short-term (up to 3 months). However:
Possible side effects
- Stomach discomfort, diarrhoea (most common)
- Nausea (less common)
- Headaches
- Drowsiness
Caution required
The use of ashwagandha is not recommended, or requires medical advice:
- During pregnancy — may cause early labour
- While breastfeeding — insufficient research
- In autoimmune diseases (RA, lupus, MS) — may stimulate the immune system
- Thyroid disorders — may raise hormone levels
- For those on sedative medication — may strengthen the effect
- In diabetes — may affect glucose levels
- Before surgery — stop at least 2 weeks before
- For children (under 18)
ALWAYS speak to your doctor before starting, especially if you take medication.
How to use it effectively
Time of day
For most people — in the evening or before bed. Ashwagandha has a mild calming effect and can therefore support sleep quality. Some take it in the morning for energy — experiment and see how the body reacts.
With food or on an empty stomach
With food — better digested, less discomfort.
Cycles vs continuous use
Traditionally used in cycles (8–12 weeks, then a break). In modern practice — both options are possible. Some studies use up to 6 months continuously.
How long until I see results
| Time | What to expect |
|---|---|
| 1–2 weeks | Possibly slightly better sleep quality |
| 4–6 weeks | Possibly less stress, better mood |
| 8–12 weeks | The maximum typical effect seen in studies |
If after 12 weeks you see no effect — ashwagandha may not suit your case.
Combining with other products
Ashwagandha can be combined with:
- Magnesium — supports similar functions
- L-theanine — synergistic effect
- Vitamin B complexes
- Other adaptogens — but with care, not all combinations have been studied
From our range — the Ecozyme Ashwagandha complex is formulated with selected ingredients.
What is really known vs marketing
| Claim | Reality |
|---|---|
| "Lowers cortisol" | There are studies showing an effect, but it is moderate |
| "Increases testosterone" | In men with low levels — possibly. In healthy men — minimal |
| "Improves sleep quality" | There are selected studies |
| "Cures anxiety" | NEVER — that is a medical claim, not acceptable |
| "Improves muscle growth" | Several studies suggest a possible effect |
| "Anti-ageing / longevity" | Traditional use; scientific research is still expanding |
Frequently asked questions
Is ashwagandha suitable for vegans and vegetarians?
Ashwagandha itself — yes, it is plant-based. But check the capsule composition — some may be made of gelatine.
Is it safe to combine with antidepressants?
Only with a doctor's permission. Ashwagandha may have a synergistic effect with SSRI and SNRI antidepressants, which can be dangerous (serotonin syndrome).
Can it be given to children?
Safety research in children is insufficient. Not recommended.
What is the difference between ashwagandha and rhodiola?
Both are adaptogens. Ashwagandha — more calming, for the evening. Rhodiola — more stimulating, for the morning. Sometimes combined for synergistic effects.
How long should it be taken?
For most studies — 8–12 weeks. Traditional practice — in courses. Long-term continuous use — less studied.
Summary
Ashwagandha is one of the better-studied adaptogens, with 3,000+ years of traditional use in Ayurveda and a growing modern scientific basis. Realistic expectations: possible support for stress, sleep and energy — but not a miracle. When choosing a product — look at standardisation (withanolides 2.5–5%), patented forms (KSM-66, Sensoril), third-party testing. Caution: in pregnancy, breastfeeding, autoimmune diseases, thyroid disorders. Always speak to your doctor. More on stress management — in our article on stress and cortisol.
