Compare every Carnosine product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Dipeptide of beta-alanine and histidine with antioxidant and anti-glycation properties
We rank Carnosine by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Carnosine is a dipeptide, which is a molecule made of two amino acids linked together. Specifically, it consists of beta-alanine and histidine. It is known for its antioxidant properties, meaning it helps protect cells from damage, and its anti-glycation properties, which means it helps stop sugar molecules from attaching to and damaging proteins in the body.
It is primarily used to reduce oxidative stress and prevent the harmful effects of glycation. By protecting proteins from sugar damage, it is often used to support overall cellular health and longevity.
To create the supplement, manufacturers combine the two amino acids, beta-alanine and histidine, through a chemical bonding process. Once the carnosine molecule is formed, it is purified and processed into a stable powder. This powder is then measured and packed into capsules or tablets for sale.
Carnosine is generally mid-range in price. This is because the process of bonding the specific amino acids together is more complex than simply sourcing a single raw nutrient, though it is not as expensive as rare or highly specialised extracts.
