Nutricost Niacin (Vitamin B3) Powder - 500g (2-Pack) - 1g per Serving

How to Uses Niacin Powder

This Nutricost niacin powder provides 1 gram (1,000 mg) per serving — a high-dose. The reference nutrient intake (RNI) for adult men is 16 mg and for women 14 mg per day, but higher doses are sometimes used under medical supervision. Start with a lower dose (e.g., 250–500 mg) to assess tolerance, then gradually increase. The flush is temporary and usually diminishes with regular uses. Mix the powder with water, juice, or a smoothie. The included scoop makes measuring easy. Always consult a health care professional before starting high-dose niacin, especially if you have liver disease, diabetes, or take medications.

Health Benefits of Niacin

Niacin contributes to normal energy-yielding metabolism by aiding the conversion of carbohydrates, fats, and proteins into usable energy. It also supports the maintenance of normal skin and mucous membranes, and contributes to normal psychological function and the reduction of tiredness and fatigue. These benefits are backed by scientific research and are authorised health claims in the UK. The well-known cardiovascular effects associated with high-dose niacin are not covered by UK authorised claims; any such uses should be discussed with a health care professional.

What Is Vitamin B3 (Niacin)?

Vitamin B3, also known as niacin, is a water-soluble vitamin essential for converting food into energy. It is involved in over 400 enzyme reactions related to metabolism, DNA repair, and cell signalling. Niacin also helps maintain healthy skin, nerves, and digestive system. The body can synthesise niacin from the amino acid tryptophan, but dietary intake is still necessary. Niacin exists in two primary forms: nicotinic acid and niacinamide. Nicotinic acid causes the harmless 'niacin flush', while niacinamide does not. This product contains 100% pure nicotinic acid, making it ideal for those seeking the classic niacin experience.

Niacin vs Niacinamide – Which Form Should You Choose?

Choosing between nicotinic acid (niacin) and niacinamide depends on your goals. Nicotinic acid is the form often linked to the flush and the classic niacin experience. It is the form used in many studies on lipid metabolism, whilst those effects are not authorised health claims in the UK. Niacinamide does not cause flushing and is often used in skin care products. This Nutricost powder contains pure nicotinic acid, delivering the traditional niacin experience. If you prefer to avoid flushing, consider niacinamide supplements.

Potential Side Effects and Safety Advice

The most common side effect of nicotinic acid is flushing — a warm, red, tingling sensation on the face and chest. This is harmless and often reduces with continued uses. Taking niacin with food or taking an aspirin 30 minutes beforehand can lessen the flush. Other possible side effects include itching, headache, or stomach upset. High doses of niacin (especially extended-release forms) have been associated with liver toxicity. Immediate-release forms like this powder have a lower risk but still require caution. Do not exceed recommended dosages. Avoid combining with alcohol or other substances that affect the liver. Discontinue uses and consult a doctor if you experience jaundice, dark urine, or persistent nausea.
