Life Extension Vitamin B3 Niacin, 500mg – 100 caps

Niacin — the third B vitamin to be identified — is the sole active ingredient in these straightforward capsules, delivered at 500 mg per capsule. Each tub contains 100 capsules, making it a generous supply for those who include B vitamins as part of their daily nutritional routine. The formula contains no unnecessary fillers beyond what is required for encapsulation, keeping things clean and simple.

Vitamin B3 plays a recognised role in the normal metabolism of glucose, fat, and alcohol within the body, and is a well-established B-complex nutrient used widely across the sports nutrition and general wellness categories. At 500 mg per capsule, this product is positioned at a higher-strength level than many standard B3 supplements found in multivitamins.

These capsules are well suited to those who prefer a single-ingredient supplement over a broad-spectrum B-complex — whether that is athletes monitoring their nutritional intake closely, or health-conscious adults looking to address a specific gap in their diet with a clearly labelled, no-ambiguity format.
