The 400 IU the NHS recommends is a minimum. For actual repletion after deficiency, 4,000 IU is appropriate.

Trying to conceive and nutritionist recommended this specific formula โ methylfolate (not folic acid), methylcobalamin B12, and iron bisglycinate. The activated forms and the gentle iron are exactly right for pre-conception nutrition.

Sublingual absorption is excellent. Let it dissolve under the tongue rather than swallowing for fastest absorption.

Biochemist specialising in ageing. NAD+ decline is one of the most well-characterised aspects of cellular ageing. NMN is the most direct precursor. Energy levels at 62 feel closer to mid-40s. The research on NMN โ NAD+ conversion in humans is now solid.
