Ashwagandha: benefits, dosage and precautions

The queen of Ayurveda, ashwagandha (Withania somnifera) is one of the most studied adaptogenic plants in the world. Its speciality: stress. We explain its benefits, the right dose, the best time to take it and the precautions to know.

What is ashwagandha?

Ashwagandha is a small shrub whose root is mainly used. Classed among the adaptogens, it helps the body better resist various forms of physical and mental stress.

The benefits of ashwagandha

  • Stress and anxiety: documented action on reducing cortisol, the stress hormone.
  • Sleep: it promotes falling asleep and more restorative sleep.
  • Energy and recovery: support for vitality and resistance to effort.
  • Emotional balance: a more stable mind day to day.

Dosage and timing

Studies most often use 300 to 600 mg of standardised root extract per day. For the stress effect, a daytime dose works; for sleep, it's preferred in the evening. As with any adaptogen, regularity is key: aim for a course of at least 4 to 8 weeks.
