Source Naturals Niacinamide B-3, Vegan Vitamin B3, 1500 mg - 50 Tablets

What is Niacinamide (Vitamin B3)?

Niacinamide, also known as nicotinamide, is one of the active forms of vitamin B3. Unlike niacin (nicotinic acid), niacinamide does not cause the characteristic redness or 'flush' when taken in high doses, making it a very popular option for those seeking the benefits of vitamin B3 without discomfort. This water-soluble vitamin participates in more than 50 enzymatic metabolic reactions, being essential for converting food into energy usable by the body.

Each Source Naturals Niacinamide B-3 tablet provides 1500 mg of pure niacinamide, a dose that widely covers daily needs. Vitamin B3 is fundamental for maintaining general health, and its supplementation can be especially useful for people with restrictive diets, chronic stress, or higher energy demands.

Benefits endorsed by the EFSA

The European Food Safety Authority (EFSA) has approved several health claims for vitamin B3. 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 statements apply to both niacin and niacinamide, as both forms are precursors to the coenzymes NAD and NADP, essential in many cellular processes.

Why choose niacinamide instead of niacin?

The main difference between niacinamide and niacin is tolerance. Niacin, even at moderate doses (50-100 mg), can cause a flushing and itching effect on the skin due to vasodilation. This effect, though harmless, is uncomfortable for many users. Niacinamide, on the other hand, does not produce this phenomenon, allowing you to enjoy the benefits of vitamin B3 without discomfort.

Furthermore, niacinamide is the preferred form in topical applications and in formulations for skin health, thanks to its calming properties and its ability to strengthen the skin barrier. For internal use, both forms are equally effective from a nutritional point of view, but niacinamide offers a more pleasant experience.

Recommended dosage and how to take it

The daily dose recommended by the manufacturer is 1 tablet per day, preferably with a meal to facilitate absorption. Each tablet contains 1500 mg of niacinamide, a dose that significantly exceeds the reference intake (which is 16 mg/day for adults), but which is within the usual supplementation range for specific purposes.

It is important to note that the maximum tolerable level (UL) established by the EFSA for nicotinamide is 900 mg per day. Higher doses, such as those in this product, should be taken under medical supervision or professional advice. It is not recommended to exceed the indicated dose without consulting a specialist.

Who should consider this supplement?

Niacinamide supplementation may be beneficial for:

• People with vegetarian or vegan diets who may have a lower intake of vitamin B3.
• Individuals with chronic fatigue or who are looking for additional energy support.
• Those who wish to maintain the health of their skin, mucous membranes, and nervous system.
• Elderly people, whose nutrient absorption may be diminished.
• Athletes who require a higher intake of B vitamins for energy metabolism.

As always, it is advisable to consult a healthcare professional before starting any supplementation, especially if other medications are being taken or if there are pre-existing medical conditions.

What are the possible side effects?

Niacinamide is generally well tolerated, but at very high doses (such as the 1500 mg in this product), mild gastrointestinal discomfort, nausea, or, rarely, headache may occur. Unlike niacin, niacinamide does not cause skin flushing.

Doses above 3 grams per day of niacinamide have been associated with liver toxicity, so it is crucial not to exceed the recommended dose without medical supervision. People with liver disease, diabetes, or blood clotting disorders should consult their doctor before taking this supplement.

If you experience any adverse effects, discontinue use and consult a healthcare professional. Keep the product out of the reach of children and store in a cool, dry place.
