Testosterone and Sleep
312 capsules across 4 ingredientsTestosterone. 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.
Sleep. Almost nothing holds an authorised GB register claim about sleep, and that absence is worth knowing in itself: sellers may not claim it either. Ingredients people discuss for sleep appear below with their actual register status, and The Sleep Charity offers evidence-based sleep advice.
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.
