Niacina Vitamina B3 Pura en Polvo (500 g)

What is Vitamin B3 (Niacin)?

Vitamin B3, also known as niacin or nicotinic acid, is a water-soluble vitamin essential for numerous bodily functions. It plays a key role in converting food into energy, maintaining skin and mucous membranes, and the functioning of the nervous system. This NuSci product offers pure niacin powder, with no additives or fillers, ideal for those seeking a high-quality, versatile supplement.

EFSA-Backed Benefits

The European Food Safety Authority (EFSA) has approved the following health claims for niacin:

• Contributes to normal energy-yielding metabolism.
• Contributes to the normal functioning of the nervous system.
• Contributes to normal psychological function.
• Contributes to the maintenance of normal skin and mucous membranes.
• Contributes to the reduction of tiredness and fatigue.

These claims are scientifically supported and allow consumers to know the real benefits of this nutrient.

Forms of Niacin: Niacin vs. Niacinamide

There are two main forms of vitamin B3 in supplements: niacin (nicotinic acid) and niacinamide (nicotinamide). Niacin is known to cause a skin flush or 'flush' effect when taken in moderate to high doses, due to vasodilation. This effect is harmless and usually subsides with continued use. Niacinamide, on the other hand, does not cause flushing and is often used in skin formulations. This product contains niacin in its pure form, ideal for those who prefer the classic form of vitamin B3.

Recommended Dosage

The recommended daily allowance (RDA) of vitamin B3 for adults in the EU is 16 mg per day (equivalent to 16 mg of niacin). However, needs may vary depending on age, sex, and health status. In high doses (greater than 50 mg/day), niacin can cause the aforementioned flush effect. It is recommended to start with low doses (25-50 mg) and gradually increase if desired. It is always advisable to consult a healthcare professional before exceeding the recommended daily dose.

Possible Side Effects

Niacin is generally well-tolerated, but in high doses, it can cause flushing, itching, or a sensation of warmth on the skin (flush). This effect is temporary and can be minimized by taking the supplement with food or using sustained-release forms. In very high doses (more than 500 mg/day), gastrointestinal discomfort, headache, or elevated liver enzymes may occur. It is not recommended for use in people with active peptic ulcer, gout, or liver disease without medical supervision. Keep out of reach of children.

How to Use This Niacin Powder?

Being a pure powder, it can be incorporated into smoothies, juices, or water. Due to its acidic taste, it is advisable to mix it with a strong-flavored drink. The dose should be measured with a precision scale (for example, 100 mg is approximately 0.1 g). Store in a cool, dry place, protected from light and heat. Shelf life of 2.5 to 3.5 years.
