Source Naturals Niacina, Vitamina B-3, No OGM - 100 mg - 100 Comprimidos

What is Niacin (Vitamin B3)?

Niacin, also known as vitamin B3, is a water-soluble B-complex vitamin essential for multiple bodily functions. This specific form, nicotinic acid, is responsible for its characteristic metabolic and vascular effects. Each Source Naturals tablet provides 100 mg of pure niacin, in a non-genetically modified (non-GMO) formula and manufactured under strict quality standards in the USA.

Vitamin B3 is naturally found in foods such as tuna, chicken, chickpeas, and peanuts, but sometimes the diet does not provide the necessary amount. Therefore, a niacin supplement can be a practical option to maintain adequate levels.

Benefits backed by the European Food Safety Authority (EFSA)

The EFSA has evaluated the scientific evidence on niacin and has approved the following health claims:

• 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 benefits make niacin a key nutrient for those seeking to maintain their daily energy, skin health, and a balanced nervous system.

Forms of Niacin: Flush Niacin vs. Niacinamide

It is important to distinguish between the two main forms of vitamin B3: niacin (nicotinic acid) and niacinamide (nicotinamide). Niacin, like the one in this product, is known to cause a flushing or 'flush' effect on the skin, especially when starting use or with high doses. This effect is temporary and occurs due to vasodilation, but it can be uncomfortable for some people.

On the other hand, niacinamide does not cause flushing and is often used in flush-free formulas. However, niacin remains the preferred form for certain metabolic benefits. Source Naturals offers niacin in its classic form, ideal for those who want to experience the full effect of vitamin B3.

Recommended Dosage and Suggested Use

The manufacturer's suggested dose is 1 tablet daily. Each tablet contains 100 mg of niacin, an amount that amply covers the recommended daily intakes for adults in the European Union (16 mg/day for men and 14 mg/day for women, although needs may vary). It is important not to exceed the recommended daily dose without consulting a healthcare professional.

To minimize the flush effect, the tablet can be taken with food or by starting with a lower dose. This product is not indicated for children or pregnant women without medical supervision.

Possible Side Effects: The Niacin Flush

Niacin, especially in doses greater than 50 mg, can cause skin redness accompanied by a sensation of warmth and itching. This effect, known as 'niacin flush,' is harmless and usually disappears within 30-60 minutes. Some people experience this effect more intensely at first, but it may decrease with continued use.

To reduce the likelihood of flushing, it is recommended to take niacin with food, avoid consuming alcohol or hot drinks at the same time, and not exceed the indicated dose. If the redness is very uncomfortable, consult your doctor, who might recommend a flush-free form such as niacinamide.

Note: this product contains niacin in the form of nicotinic acid. It should not be confused with niacinamide. Read the label carefully.

Who should consider a niacin supplement?

A niacin supplement can be beneficial for people with restrictive diets, such as vegetarians or vegans, who may have a lower intake of vitamin B3. Also for those who experience frequent fatigue, dry or flaky skin problems, or wish to support their nervous system. It is always advisable to consult a healthcare professional before starting any supplementation, especially if other medications are being taken.
