Ashwagandha: more muscle strength, more lean body mass, lower fat percentage

Withania somnifera / Ashwagandha
If healthy people take 3-5 ashwagandha capsules every day, their muscle strength and lean body mass increase and their fat percentage decreases. In addition, taking this herb, which is used in the ayurveda tradition, reduces the chance of cardiovascular disease. Researchers at the ICMR Advanced Centre for Reverse Pharmacology in Traditional Medicine discovered this.

Ashwagandha
In the classical Indian tradition of ayurvedic medicine, ashwangandha, like shilajit, is a rasayana: a remedy with a rejuvenating effect. Traditional healers in India prescribe ashwagandha mainly as a medicine that can improve general health and condition. The researchers carried out this study to find out whether the same effects were found in healthy men and women.

Study
They gave 12 men and 6 women aged 18-30 an extract of ashwagandha for a period of 30 days. On days 1-10 the dose was 750 mg per day, on days 11-20 it was 1000 mg per day, and on days 21-30 the dose was 1250 mg per day. The subjects took half the total daily dose twice a day.

The researchers studied the subjects twice before administration of the extract started. Administration of the extract started just after the second time that the researchers had seen the subjects [Visit 2].

On days 11 [Visit 3], 21 [Visit 4] and 31 [Visit 5], the researchers examined the subjects again.

Lean body mass
The figure below shows how the subjects' lean body mass rose by just less than two kilograms, and their fat percentage decreased by over two percent after they had taken ashwagandha. To be precise: the extract reduced the average fat percentage from 27.78 to 25.51 percent.

Strength
The researchers also measured the amount of strength the subjects could generate with their hands, their quadriceps and their lower back. These all increased during the supplementation period.

The strength effects in the quadriceps and lower back were statistically significant; the strength effect in the hands was not.



Lipids
Ashwagandha supplementation reduced the concentration of triglycerides in the blood by a significant amount. The decline in LDL concentration was almost significant.

Side effects
The researchers also used the trial to assess whether ashwagandha was safe in the fairly high doses that were used. One person at least suffered from side effects.
