Vitamin B3, also known as niacin, is an essential B vitamin that plays a critical role in energy production, cardiovascular health, cholesterol metabolism, brain function, and overall metabolic performance. As a water-soluble vitamin, niacin is involved in hundreds of enzymatic reactions that help convert food into usable energy and support healthy cellular function.
At TigerFitness.com, our vitamin B3 (niacin) supplements are selected for purity, proper dosing, and form-specific effectiveness, making them ideal for both health-focused individuals and performance-driven athletes.
Vitamin B3 refers to a group of compounds that include nicotinic acid, niacinamide (nicotinamide), and inositol hexanicotinate. Each form supports the body in slightly different ways:
Nicotinic acid – Known for supporting cholesterol levels and circulation; may cause the characteristic “niacin flush”
Niacinamide – Supports cellular energy and nervous system health without flushing
Inositol hexanicotinate – A slower-release form often used to reduce flushing effects
Niacin is essential for the production of NAD and NADP, two coenzymes required for energy metabolism, DNA repair, and cellular resilience.
Niacin is vital for converting carbohydrates, fats, and proteins into usable energy, supporting daily performance, endurance, and metabolic efficiency.
Vitamin B3—especially nicotinic acid—has long been used to support healthy cholesterol levels, circulation, and cardiovascular function when used as directed.
Niacin supports cognitive function, neurotransmitter activity, and nervous system balance, contributing to mental clarity and focus.
Niacin plays a role in skin integrity and cellular repair, supporting healthy skin and tissue maintenance at the cellular level.
By supporting circulation and energy metabolism, niacin may help improve nutrient delivery, workout performance, and recovery, particularly during intense training phases.
Vitamin B3 (niacin) supplements are commonly used by:
Individuals supporting heart and cholesterol health
Athletes and lifters optimizing energy metabolism
Adults focused on brain and nervous system support
Users addressing dietary B-vitamin gaps
Niacin stacks well with B-complex vitamins, magnesium, omega-3s, CoQ10, and general cardiovascular or metabolic support supplements.
Because dosing and form matter with niacin, Tiger Fitness prioritizes supplements that offer:
Clearly labeled niacin form and dosage
Clean, pharmaceutical-grade ingredients
Flush and non-flush options
Manufactured under strict quality and safety standards
Our curated selection ensures effectiveness, transparency, and user confidence.
Vitamin B3 supplements are typically taken:
With meals to improve tolerance
Daily as part of a wellness or performance routine
According to label directions
Some forms of niacin may cause a harmless flushing sensation. Start with lower doses and consult a healthcare professional before use—especially if managing cholesterol, blood pressure, or other medical conditions.
