Ashwagandha (Withania somnifera) is a small evergreen shrub native to India and parts of Africa. Its root has been central to Ayurvedic practice for over two thousand years, classed there as a rasayana or rejuvenative tonic.
In modern terms it is described as an adaptogen. The NCCIH evidence summary is worth reading before buying any formula containing it.
Caveat worth stating: many trials are small and quality varies. The honest summary is more evidence than most botanicals in this space, and less than a pharmaceutical.
Studies typically run eight to twelve weeks and use 300 to 600 mg daily of standardised root extract. Very few examine acute single-dose effects, because that is not how adaptogens are proposed to work.
Taking it for three weeks and concluding nothing happened means stopping before the window the research measured in.
Ashwagandha targets stress load, which is one of the largest real-world drains on energy and drive in working-age men — and unlike age or genetics, an input you can influence.
Judge it at week eight, with medical clearance if any caution above applies. See where it sits in the formula.
