Best perimenopause supplements to buy in 2026
Most perimenopause supplement marketing is noise. A small number of products have real evidence behind them for women in their 40s and 50s: magnesium glycinate for sleep, vitamin D and K2 for bone density, omega-3 for joint pain and mood, creatine monohydrate for strength and cognition, and protein when food alone is not getting you there.
Quick answer
Third-party testing (NSF, Informed Sport or USP) rather than proprietary blends with undisclosed doses. Options below start around £14.99, sold directly by Shopify merchants.

What to look for
- Third-party testing (NSF, Informed Sport or USP) rather than proprietary blends with undisclosed doses.
- Doses that match the research: 300 to 400mg elemental magnesium, 3 to 5g creatine monohydrate, 1000 to 2000mg combined EPA and DHA.
- One change at a time, so you can tell what is actually working.
Supplements are not regulated like medication. Nothing here treats or prevents disease, and a supplement will not out-run an under-fuelled diet.
