HelloPharmacist Scorecard of Beta Alanine 750 mg by NOW Sports
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: 750 mg of CarnoSyn, which is beta-alanine, an amino acid your body uses to build carnosine, a compound that may play a role in muscle and nerve function. The capsule also holds inactive ingredients — rice flour, hypromellose (a plant-based capsule material), stearic acid, and ascorbyl palmitate — that serve as fillers and binders.
Does it work?
Moderate evidence
Beta-alanine is possibly effective for athletic performance and physical performance, meaning there's reasonable evidence it may help, though the research isn't definitive. For age-related cognitive decline, cognitive function, COPD, and menopausal symptoms, the evidence we hold isn't established — there's either too little data or the quality isn't sufficient to make a claim either way.
How safe is it?
Well-documented data
Beta-alanine is generally well tolerated in healthy adults, but it commonly causes a harmless tingling sensation (paresthesia) and flushing, usually starting on the scalp within 20 minutes and lasting about an hour. The tingling is dose-dependent: very mild at lower doses and more noticeable at higher ones.
The product hasn't been studied for long-term use at high doses. There isn't enough safety information during pregnancy or breastfeeding, so the data advises against it in both.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That said, if you take any medications, check them against the tool on this page or confirm with your own pharmacist before starting.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
This is for people looking to support athletic or physical performance with an amino acid that's been studied in that context. If you're pregnant, breastfeeding, or take any medications, talk with your own doctor or pharmacist first.
Expect the tingling — it's normal and harmless, but it's worth knowing it's coming.

Suggested/Recommended/Usage/Directions
Suggested usage: Take 3 capsules 2 to 3 times daily with water or your favorite beverage. For best results, allow at least 2 hours between doses.
Formula
Beta-Alanine is a non-essential amino acid that is used by muscle cells to synthesize carnosine. Carnosine is a dipeptide (Beta-Alanine plus Histidine) that functions as a buffer for the hydrogen ions (acid) produced during strenuous exercise, thus helping to maintain optimum muscular pH. NOW Sports uses CarnoSyn, a patented form of Beta-Alanine that has been clinically tested and shown to increase muscle carnosine content, allowing muscles to work harder and longer during intense exercise. NOW Sports Beta-Alanine is backed by scientific research demonstrating that CarnoSyn supplementation results in delayed muscle fatigue and rapid recovery time, thereby helping you attain your strength and endurance training goals.

Beta-Alanine may cause a harmless, temporary tingling sensation on the skin for some individuals. After a few weeks of supplementation with Beta-Alanine, this sensation normally lessens or subsides.
Consult physician if pregnant/nursing, taking medication, or have a medical condition.
