21st Century Niacina 250 mg, 220 tabletas

What is Niacin (Vitamin B3)?

Niacin, also known as vitamin B3, is an essential nutrient that the body needs to convert food into energy. It is part of the B vitamin complex and plays a key role in the functioning of the nervous system, skin and mucous membrane health, and the reduction of tiredness and fatigue. This 21st Century supplement provides 250 mg of niacin per tablet, a significant dose for those looking to support their energy metabolism.

Being a water-soluble vitamin, the body does not store it in large quantities, so regular intake through diet or supplements is important. Niacin is naturally found in foods such as lean meats, fish, legumes, and nuts, but sometimes an extra supply may be necessary to meet daily needs.

EFSA-backed benefits

The European Food Safety Authority (EFSA) has approved several health claims for niacin. These include:

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

These claims are based on solid scientific evidence and are the only ones permitted in the European Union for this nutrient. Our product aligns with these benefits, offering a pure and effective form of niacin.

Forms of niacin: niacin vs. niacinamide

Niacin comes in two main forms: nicotinic acid (niacin) and nicotinamide (niacinamide). Although both are forms of vitamin B3, they have key differences. Nicotinic acid can produce a temporary flushing effect on the skin, especially at high doses, due to vasodilation. This effect is harmless and disappears with continued use. Niacinamide, on the other hand, does not cause this flushing, but it also does not share all the same metabolic benefits. Our product uses niacin (nicotinic acid), which is the classic and most studied form for energy metabolism.

Recommended dosage and possible side effects

The recommended dose for adults is one tablet daily, preferably with a meal. The recommended daily dose should not be exceeded without consulting a healthcare professional. At doses above 50 mg, niacin can cause a skin flushing effect, characterized by warmth, itching, and redness on the face and torso. This effect is temporary and not dangerous. To minimize it, the tablet can be taken with food or the dose divided. If you experience persistent discomfort, consult your doctor. Food supplements should not be used as a substitute for a balanced and varied diet or a healthy lifestyle.

Frequently asked questions about niacin

How much niacin do I need per day?

Recommended intakes vary according to age, sex, and physiological situation. For adults, the recommended daily intake (RDI) is 16 mg/day for men and 14 mg/day for women.

This supplement provides 250 mg, a much higher amount than the RDI, so it is recommended not to exceed the indicated dose.

If you are pregnant, breastfeeding, taking medication, or have any medical condition, consult your doctor before taking this supplement.

Is this product suitable for vegans?

The tablets do not contain ingredients of animal origin, making them suitable for vegan and vegetarian diets.
