Ashwagandha has been used in Ayurvedic medicine for over 3,000 years and is now one of the most sought-after supplements in Spain. It's not a passing fad: science supports what ancient peoples already intuited. If stress, fatigue, or insomnia are part of your daily life, keep reading because ashwagandha could be exactly what you need.

What is ashwagandha and why is it called an adaptogen?

Ashwagandha (Withania somnifera) is a plant native to India and North Africa. It is classified as an adaptogen, a term describing plants capable of helping the body adapt to stress—physical, mental, or emotional—without disrupting the body's normal functions.

Unlike stimulants, adaptogens do not overexcite the nervous system. Instead, they modulate the hypothalamic-pituitary-adrenal (HPA) axis, responsible for the cortisol response. The result: less reactivity to stress and more overall balance.

Main benefits of ashwagandha

Reduction of stress and anxiety

This is its most studied benefit. A clinical trial published in Medicine (2019) with 240 mg daily of root extract showed a significant reduction in cortisol levels and perceived stress symptoms. Participants reported greater calm and improved concentration after 60 days of use.

Improved sleep

Ashwagandha acts on the GABAergic system, facilitating relaxation and sleep onset. A study in adults with insomnia found improvements in sleep quality, time to fall asleep, and feeling rested upon waking. If you find it hard to unwind at night, combining it with other plants from our sleep and rest section can make a difference.

Energy and physical performance

Paradoxically, a relaxing plant also improves energy. By reducing chronic cortisol—which depletes the body's reserves—ashwagandha frees up underlying energy. Several studies in athletes have documented improvements in muscle strength, aerobic endurance, and post-exercise recovery. It can be a good complement within a sports nutrition routine.

Immune system support

Chronic stress suppresses defenses. By regulating cortisol, ashwagandha indirectly helps maintain a healthy immune response. Combined with other supplements from the defenses and immunity section, it can be a good ally during seasonal changes.

How much ashwagandha to take and when?

The most commonly used dose in clinical studies is 300–600 mg per day of standardized extract of withanolides (active compounds). The capsule or standardized extract form is the most practical and ensures consistent concentration.

Regarding timing:

• In the morning if you are looking to improve energy and concentration during the day.
• At night if the main goal is to sleep better or reduce nocturnal cortisol.
• Divided into two doses (morning and night) for a more sustained effect.

It is recommended to take it with meals to improve digestive tolerance.

Is it safe? Contraindications and precautions

Ashwagandha is generally well-tolerated at standard doses. However, there are situations where it is advisable to consult a doctor before taking it:

• Pregnancy and breastfeeding: not recommended due to its effect on hormones.
• Autoimmune diseases (lupus, multiple sclerosis, rheumatoid arthritis): it could stimulate the immune system.
• Thyroid medication: ashwagandha can increase thyroid hormone levels.
• Sedatives or anxiolytics: it may enhance their effect.

For most healthy people, an 8–12 week cycle followed by a 4-week break is a good guideline.

How to choose a good ashwagandha supplement

Not all products on the market are the same. What to look for on the label:

• Standardized extract: ideally with 5% or more withanolides.
• KSM-66 or Sensoril: these are the most studied patented forms, with higher bioavailability.
• No unnecessary fillers or additives.
• Quality certifications (GMP, third-party analysis).
