Ashwagandha: benefits, what science says and how to take it

Start with the essentials: ashwagandha may help reduce stress and improve sleep quality, but the evidence is emerging and results vary from person to person. It is not a miracle cure, and it will not promise to eliminate anxiety or guarantee perfect sleep. That said, there are reasons to consider this adaptogenic plant, as long as you know what to expect.

What is ashwagandha and what is it for?

Ashwagandha (Withania somnifera) is a plant used for centuries in Ayurvedic medicine, native to India and parts of Africa. Its roots are traditionally used to promote vitality and resilience to stress. In the modern context, it is classified as an adaptogen — a substance believed to help the body adapt to stressors, whether physical, chemical or biological.

What exactly is it for? Current research focuses on two main effects: reducing stress and improving sleep. Small studies suggest that ashwagandha may lower cortisol levels, the stress hormone, and improve perceived well-being. However, most of these studies have small samples and short durations, which limits the strength of the conclusions.

There is also interest in its potential to improve memory, muscle strength and even reproductive health, but the evidence is even more preliminary. We cannot say that ashwagandha treats any health condition — that would be illegal and, more importantly, scientifically incorrect.

What do we actually know about ashwagandha?

Let's separate what has some scientific support from what is merely speculation. The following list reflects the current state of research, but remember: having some scientific support is not the same as it working for you.

• Stress reduction: The available research points to a reduction in stress symptoms and mild anxiety. The most prudent reading of the available research is that it may help with mild symptoms, with trials still small and heterogeneous.
• Sleep improvement: The evidence on sleep goes in the same direction: possible improvement in sleep quality, especially in those reporting mild insomnia. The effect seems more evident at higher doses and after a few weeks of use.
• Possible increase in energy and focus: Some studies suggest that ashwagandha may improve attention and resistance to fatigue, but the evidence is less consistent.
• Effects on strength and muscle recovery: There are small studies showing improvements in strength and body composition in men who train for strength, but the results are mixed.

There is no solid evidence for benefits such as reducing inflammation, controlling blood sugar or preventing disease. If someone promises you that, be wary.

How does ashwagandha work in the body?

The exact mechanism is not fully known, but it is believed that the active compounds, called withanolides, influence the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the stress response. In simple terms, ashwagandha may help regulate cortisol production, preventing excessive spikes in stressful situations.

In addition, some animal studies suggest that ashwagandha has neuroprotective effects and may influence neurotransmitters such as GABA, which is involved in relaxation. However, these mechanisms are still being explored and we should not extrapolate animal results to humans.

How long does it take to work?

This is a common question, and the answer is: it depends. Reported timelines vary widely: some describe effects within 30 days, and trials only measure at 8 weeks. Most clinical trials use periods of 8 to 12 weeks to assess effects on stress and sleep.

Do not expect an immediate change. Ashwagandha is not a sedative — it will not make you fall asleep in the middle of the afternoon. It is more like a gradual adjustment of the system. If you feel nothing after 8 weeks of consistent use, it is probably not the right supplement for you.

What is the recommended dose and how to take it?

Doses used in studies range from 300 mg to 600 mg of standardised extract, once or twice a day. However, there is no official recommended dose from the EFSA (European Food Safety Authority) for ashwagandha, as no specific health claim has been approved yet.

If you choose a supplement, follow the manufacturer's instructions and start with the lowest dose. Ashwagandha is available in various forms: capsules, powder, drops and gummies. The choice depends on your preference, but consistency is more important than the form.

At TuttiBear, the Stress Relief Gummies are the option with ashwagandha, for those who prefer a practical and tasty form. The Sleep Well Gummies take another path — melatonin — to support a nighttime routine, and the Daily Focus Gummies, for those seeking mental clarity during the day. Remember that these products are food supplements, not medicines.

What are the side effects and precautions?

Ashwagandha is generally well tolerated, but it can cause mild side effects such as stomach upset, diarrhoea or drowsiness. At high doses, there are reports of gastrointestinal irritation.

There are important precautions: it is not recommended for pregnant or breastfeeding women, nor for people with autoimmune diseases, as it may stimulate the immune system. If you take medication for thyroid, blood pressure or blood sugar, talk to your doctor before starting, as there may be interactions.

It is also important to note that ashwagandha may cause drowsiness, so do not drive or operate machinery until you know how you react. And, of course, do not combine it with alcohol or other sedatives without professional advice.

Ashwagandha in gummies: is it worth it?

Gummies are a convenient way to take supplements, especially for those who have difficulty swallowing pills. The main advantage is practicality and taste, which can help maintain consistency.

However, gummies may contain sugar or sweeteners, and the dose of extract may be lower than in a capsule. Check the label to know the amount of ashwagandha per gummy. Whatever the format, what matters is the total daily dose, not the form.

If you choose gummies, choose a product that clearly states on the label the amount of extract and the concentration of withanolides.

Ashwagandha vs. other stress supplements

There are other popular stress supplements, such as valerian, passionflower or magnesium. Ashwagandha stands out for being an adaptogen, meaning it acts on stress regulation in a more systemic way, while others are more sedative.

There is no universal answer as to which is better. It depends on your sensitivity and what you are looking for. If you want something to calm down before bed, valerian may be more direct. If you want support throughout the day to cope with stress, ashwagandha may be more suitable.

At TuttiBear, we have specific products for each moment — the Stress Relief Gummies for the day, and the Sleep Well Gummies for the night. The Sleep Ritual is a combination that may be useful for those who have difficulty switching off at night.

What do scientific studies say?

Let's be clear: research on ashwagandha is promising, but still limited. Most studies have fewer than 100 participants and last between 8 and 12 weeks. Available systematic reviews point to moderate evidence for stress reduction, and consistently call for more high-quality trials.

There are no long-term studies evaluating long-term safety, nor effects in specific populations such as children or the elderly. Therefore, ashwagandha should be used with caution and for limited periods, with breaks.

If you are looking for a miracle solution, ashwagandha is not it. If you are willing to try it with realistic expectations, it can be a useful tool in managing stress and sleep.

Where to buy quality ashwagandha?

Choose brands that state the concentration of withanolides and are transparent about the origin of the extract. Be wary of very cheap products or those that do not specify the dose.

At TuttiBear, the dose of each ingredient is stated on the label of each product. Our Stress Relief Gummies are the practical way to incorporate ashwagandha into your routine. Always consult your healthcare professional before starting any supplement, especially if you have medical conditions.

What to do next?

If you decide to try ashwagandha, start with a low dose, take it consistently at the same time, and note how you feel over 4 to 8 weeks. Do not combine it with other stress supplements without advice. If you do not notice a difference, do not insist — there are other options.

And remember: a supplement does not replace a balanced lifestyle. Stress and sleep depend greatly on factors such as exercise, diet and sleep hygiene. Ashwagandha can be a support, but it is not the complete answer.

If you have questions about which product to choose, talk to us or your pharmacist. We are here to help, but the final decision is always yours.
