Niacinamide B3 1500 mg 100 Tablets by Source Naturals – Cellular Energy Support Vitamin B3
Niacinamide B3 1500 mg tablets by Source Naturals provide a concentrated, single-vitamin formula for normal cellular energy metabolism. Each tablet supplies 1,500 mg of vitamin B3 as niacinamide, a form distinct from nicotinic acid and its characteristic flushing.
This 100-tablet bottle is a single-nutrient supplement, not a B-complex or multivitamin. It supplies one specific B vitamin rather than a combination of all the B vitamins. The high strength makes professional guidance important: more vitamin B3 does not automatically mean more energy, and this amount is far above ordinary daily nutritional requirements.
Key Niacinamide B3 1500 mg 100 Tablets Benefits
- Provides vitamin B3 used to form coenzymes that help cells transfer energy from carbohydrates, fats, and proteins into forms they can use.
- Supports normal nutrient processing through vitamin-dependent enzyme reactions, connecting dietary B3 with everyday cellular metabolism rather than stimulant activity.
- Contributes to the coenzyme systems involved in making fatty acids and maintaining normal cellular antioxidant function.
How Niacinamide B3 1500 mg 100 Tablets Works
Your body uses niacinamide for NAD production. NAD is a coenzyme, meaning it helps enzymes carry out their work. Its oxidized and reduced forms, NAD+ and NADH, carry electrons during reactions that break down food and help generate ATP, the energy currency used by cells.
A related coenzyme, NADP, supports building processes, including fatty acid synthesis. Its reduced form, NADPH, also helps maintain cellular antioxidant systems. These complementary roles explain why B3 participates in both obtaining energy from nutrients and producing substances cells need. They do not mean a high-dose tablet produces a noticeable energy boost or replaces adequate food intake.
Key Functional Ingredients Include:
- Niacinamide: Supplies a vitamin B3 building block for NAD and NADP. These coenzymes help enzymes move electrons during nutrient metabolism, supporting normal cellular energy production and synthesis of fatty acids. Niacinamide is also called nicotinamide; it is not nicotinamide riboside or nicotinic acid.
Niacinamide B3 1500 mg 100 Tablets Is Formulated For
- Adults whose healthcare practitioner has recommended a concentrated niacinamide supplement rather than routine low-dose B3 supplementation.
- People comparing a single-vitamin tablet with broader B-complex products and wanting to understand exactly which B3 form they are choosing.

Frequently Asked Questions About Niacinamide B3 1500 mg 100 Tablets
What are the benefits of Niacinamide B3 1500 mg 100 Tablets?
This Source Naturals formula supplies vitamin B3 as niacinamide, which the body uses to make NAD and NADP. Those coenzymes support the normal processing of carbohydrates, fats, and proteins and help cells carry out energy-producing reactions. B3 also participates in fatty acid synthesis and cellular antioxidant function. The tablet provides 1,500 mg, so it is a concentrated option rather than a routine daily nutritional dose. It should not be expected to act like a stimulant or guarantee increased energy.
Who should take Niacinamide B3 1500 mg 100 Tablets?
This high-strength niacinamide tablet is best considered by adults whose healthcare practitioner has identified a reason for concentrated B3 supplementation. It is not a substitute for a complete B-complex, because it does not supply the other B vitamins. The manufacturer directs one tablet daily. Because each tablet contains 1,500 mg, discuss your total B3 intake, medications, and health history before starting. Pregnancy, possible pregnancy, and breastfeeding require consultation with a health care professional before use.
Are there any side effects of taking Niacinamide B3 1500 mg 100 Tablets?
Niacinamide can cause digestive upset; higher intakes can cause liver toxicity, and low platelet counts are a concern with kidney disease. Use this 1,500 mg product under medical supervision and review medications and other B3 supplements. The label states: If you are pregnant, may become pregnant, or breastfeeding, consult your health care professional before using this product. Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children.
How does Niacinamide B3 1500 mg 100 Tablets support overall health?
Vitamin B3 supports overall nutrition by supplying material for coenzymes involved in fundamental cellular work. NAD helps transfer energy from food into ATP, while NADP supports synthesis reactions and antioxidant systems. Niacinamide is one route the body uses to obtain these coenzymes; it is different from nicotinic acid and nicotinamide riboside. This Source Naturals product provides a concentrated 1,500 mg serving, so its place in a wellness routine depends on individual needs and professional guidance, not a promise that higher intake improves health.
