10 Proven Health Benefits of Ashwagandha (With Dosage & Side Effects)

1. What is Ashwagandha?

Ashwagandha is an ancient medicinal herb with rich roots in Indian Ayurvedic tradition. For more than 3,000 years, it has been used to relieve stress, elevate energy levels, and enhance cognitive concentration.

"Ashwagandha" translates to "smell of the horse" in Sanskrit, referring both to its unique herbal scent and its traditional reputation for conferring the vitality and stamina of a stallion.

2. Can reduce stress and anxiety

Ashwagandha is best known for its potent stress-relieving properties. It mediates the hypothalamic-pituitary-adrenal (HPA) axis, a complex neuroendocrine system regulating the body's physiological response to stress.

In a 60-day randomized study in 64 people with chronic stress, those in the group who supplemented with 300 mg of full-spectrum ashwagandha root extract reported an average 69% reduction in anxiety and insomnia, compared with 11% in the placebo group.

3. May lower blood sugar and fat

A review of 24 studies, including 5 clinical studies in people with diabetes, found that treatment with ashwagandha significantly reduced blood sugar, hemoglobin A1c (HbA1c), insulin, blood lipids, and oxidative stress markers.

4. Increases muscle and strength

Research indicates that ashwagandha may improve muscle mass, muscular endurance, and body composition. In one trial, male participants who took 600 mg of ashwagandha daily and underwent resistance training for 8 weeks had significantly greater gains in muscle strength and muscle size compared with the placebo group.

5. Sharpening focus and sleep quality

Triethylene glycol, an active compound found in ashwagandha leaves, has been shown in clinical trials to promote restorative non-REM sleep. Patients suffering from mild insomnia experienced faster sleep onset latency and reported waking up feeling significantly more refreshed.

6. Optimal dosage and safety precautions

Dosing recommendations vary depending on the extract concentration. Typical dosages range between 300 mg to 600 mg per day, preferably taken with breakfast or before bedtime. Ashwagandha is considered safe for most healthy adults, but pregnant or breastfeeding individuals and those with thyroid disorders should consult a healthcare provider first.
