Source Naturals Niacin 250 mg, Vegan Vitamin B3, 250 Tablets

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 metabolism of carbohydrates and fats. In addition, it contributes to the normal functioning of the nervous system and the maintenance of healthy skin. Unlike other vitamins, niacin can be obtained from both food sources and supplements, being especially useful for those on restrictive diets or with greater nutritional needs.

This Source Naturals supplement provides 250 mg of niacin per tablet, in its nicotinic acid form, which is the most studied and used. It is a vegan, gluten-free option, manufactured under strict quality controls.

Benefits backed by EFSA

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 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 officially recognized. Therefore, including niacin in the daily diet can be an effective way to support these vital functions.

Forms of niacin: niacin vs. niacinamide

Vitamin B3 comes in two main forms: niacin (nicotinic acid) and niacinamide (nicotinamide). Both have similar functions but differ in their side effects and applications. Niacin, the form used in this product, is known to produce a flushing or warming effect on the skin when taken in high doses. This is due to vasodilation and is not harmful, although it can be uncomfortable for some people.

Niacinamide, on the other hand, does not cause flushing and is often used in skin formulations. However, the nicotinic acid form has more studies related to lipid metabolism and energy. For those looking to avoid flushing, sustained-release niacin or inositol hexanicotinate presentations are available, although standard niacin is still the most common and economical.

Recommended dosage and how to take it

The recommended daily dose of niacin varies depending on age, sex, and individual needs. For adults, reference intakes range from 14 to 16 mg per day. However, supplements like this one often contain much higher doses (250 mg) for specific purposes. It is important not to exceed the indicated dose without consulting a healthcare professional.

It is suggested to take 1 tablet daily with a meal to improve absorption and reduce possible stomach upset. The tablets are vegan, free of yeast, dairy, egg, gluten, soy, or wheat, and contain no added sugars, starch, preservatives, or artificial colors.

Possible side effects (flush)

The most well-known side effect of niacin is skin flushing, accompanied by a sensation of warmth and itching. This occurs especially with high doses (from 50 mg) and usually lasts between 15 and 30 minutes. It is harmless and tends to decrease with continued use. To minimize it, it is recommended to take the supplement with food or divide the dose throughout the day.

In rare cases, gastrointestinal discomfort may occur. People with liver disease, ulcers, or clotting problems should consult their doctor before taking niacin in high doses. Its use during pregnancy or lactation is not recommended without professional supervision.
