NuSci Niacin Vitamin B3 Pure Powder - 500g (1.1 lb)

Niacin Forms: Nicotinic Acid vs. Niacinamide

Vitamin B3 exists mainly as nicotinic acid or niacinamide (nicotinamide). The powder offered here is nicotinic acid – the classic form renowned for its temporary flushing effect, a harmless sensation of warmth and redness that typically lessens with regular use. Niacinamide does not cause flushing but also lacks the lipid-modulating effects linked to nicotinic acid.

A third type, inositol hexanicotinate, is marketed as a “no-flush” niacin, but its conversion to active niacin varies. For those seeking the full range of niacin’s nutritional benefits, pure nicotinic acid is the preferred form amongst researchers and clinicians.

Key Health Benefits of Niacin Supplementation

Vitamin B3 contributes to normal energy-yielding metabolism, helping your body efficiently use carbohydrates, fats, and proteins. It also supports the normal function of the nervous system and helps maintain healthy skin and mucous membranes. In addition, niacin contributes to the reduction of tiredness and fatigue, making it a popular choice for maintaining sustained daily energy.

These benefits are recognised by the European Food Safety Authority. This product is a food supplement and should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.

What Is Niacin (Vitamin B3)?

Niacin, commonly known as vitamin B3, is a water-soluble vitamin essential for converting food into energy. It plays a crucial role in the function of over 400 enzymes involved in metabolism, DNA repair, and cellular signalling. This pure powder form – nicotinic acid – is the classic niacin variant used for decades in nutritional support.

The fine white crystalline powder has a characteristic sour taste and dissolves readily in water, making it ideal for custom encapsulation, blending, or direct use under professional guidance.

Potential Side Effects and Safety Considerations

The most common side effect of nicotinic acid is temporary flushing, characterised by redness, warmth, and tingling of the skin. This reaction is harmless and often diminishes with continued use. Taking niacin with food or using an extended-release form can reduce flushing. Other possible effects include mild gastric discomfort or headache.

High doses of niacin (above 500 mg/day) may require medical supervision, as they can affect liver enzymes or blood sugar levels. Individuals with liver disease, diabetes, gout, or peptic ulcers should consult a health care professional before use. Pregnant or nursing women should also seek medical advice.

Do not exceed the stated dose. Keep out of reach of children. This product is a food supplement – not intended to diagnose, treat, , or prevent any disease.
