Carnosine is a dipeptide (made of beta-alanine and histidine) naturally present in skeletal muscle. It acts as an intracellular buffer, neutralising the hydrogen ions (H+) that build up in muscles during intense exercise — the cause of the muscular “burn” and fatigue that forces you to stop. Beta-alanine is the limiting factor in carnosine synthesis, so beta-alanine intake determines how much carnosine your muscles can store.

The CarnoSyn form used by Nutrimuscle is a patented raw material evaluated in more than 55 published clinical studies. Trials have shown a 40–80% increase in muscle carnosine after 4 to 10 weeks of regular supplementation, with the main benefits seen for efforts lasting 1 to 10 minutes — weight-training sets of 8+ reps, running intervals, combat-sport rounds, CrossFit WODs and middle-distance swimming.

In weight training, beta-alanine helps you complete more reps before failure, particularly on longer sets (12–25 reps) and intensity techniques like drop sets. In CrossFit and HIIT it helps maintain intensity across a WOD. In combat sports, buffering capacity supports punching power and speed across 3–5 minute rounds. In middle-distance running and swimming, it helps where muscular acidosis limits performance.

Take 3.2 to 6.4 g a day, split into two doses to minimise the harmless, temporary tingling sensation (paraesthesia) that often accompanies beta-alanine — it usually fades within 30–60 minutes. Sensitive users can split the dose into 3–4 smaller servings. A minimum 4-week course is needed for a meaningful rise in muscle carnosine; effects continue building up to 10–12 weeks. At 4.8 g/day, a 240 g pot lasts around 50 days.

For adults engaging in physical activity. Not a substitute for a varied, balanced diet. Do not exceed the recommended daily dose. Not recommended for pregnant or breastfeeding women. If under medical treatment, consult a healthcare professional before use.

Is the tingling sensation from beta-alanine dangerous?

No — paraesthesia is a well-known, harmless, temporary effect caused by activation of skin nerve receptors, fading within 30–60 minutes. Splitting the dose reduces it.

How long does a 240g pot last?

At the average dose of 4.8 g/day it lasts about 50 days; at the minimum 3.2 g/day, 75 days; at the maximum 6.4 g/day, about 37 days.
