Libido and Fertility and Testosterone
668 capsules across 7 ingredientsLibido. Almost no ingredient holds an authorised register claim in this area, which is itself useful information: sellers may not claim what is not authorised. What people discuss appears below with its actual register status.
Fertility. Ingredients here hold register claims relating to fertility and reproduction, quoted exactly. UK guidance on folic acid before and during early pregnancy is the best-established nutritional advice in this area, and Fertility Network UK below offers wider support.
Testosterone. Only a small number of ingredients hold register claims mentioning testosterone, and this page quotes them exactly. Claims in this category are heavily marketed well beyond what the register authorises; the split below shows the line.
Nothing here is medical advice. The wording is the GB register's, quoted exactly; whether a product qualifies to use it is the seller's responsibility. Speak to a GP or pharmacist before taking a supplement, especially if you are pregnant, take medicines or have a diagnosed condition. Wording from the GB nutrition and health claims register; mapping reviewed 4 September 2026.
