What zinc actually does in the body, who’s most likely to be deficient, and how to choose and dose a supplement safely.
Health Tips for Supplement Spotlights
In-depth looks at individual supplements and ingredients, one at a time.
Folic acid vs methylfolate: what NHS, NICE and UKTIS guidance actually says — including why folic acid, not methylfolate, remains the evidence-backed standard for pregnancy.
What research genuinely supports about combining vitamin D3 and K2 for bone and heart health — including the honest limitations researchers themselves acknowledge.
What magnesium actually does, how citrate and glycinate differ, and how to choose between two popular UK options — including safety notes on bisphosphonates.
What research genuinely supports about reishi, cordyceps and lion’s mane — honest about what’s established and what’s still early-stage lab research.

As with the rest of VitMax, these spotlights are written to explain the evidence as it stands, not to oversell a single ingredient as more effective than the research supports.
