Verdict
Not enough evidence
Ashwagandha and magnesium work well taken together because they act on different pathways.
1 source: 1 negative
By Arun AgrahriLast reviewed 1 timecoded source
Short answer
Yes. They are often paired, and they work on different pathways: ashwagandha lowers cortisol, and magnesium supports GABA activity and muscle relaxation. Peter Attia's nighttime routine combines ashwagandha, glycine and magnesium L-threonate.

Yes, ashwagandha and magnesium can be taken together, and they are often paired. Peter Attia's nighttime routine combines ashwagandha, glycine and magnesium L-threonate. The pair also turns up in advice for adrenal recovery and in evening sleep routines, where magnesium sits in the sleep stack and ashwagandha goes alongside apigenin for cortisol.
The two work on different pathways. Ashwagandha lowers cortisol, while magnesium works on GABA, a calming brain chemical, and relaxes muscle. One takes the hormone side of stress and the other takes the nerve side.
Take both 30-60 minutes before bed, since nothing here blocks absorption.
