Source Naturals Niacinamide B-3, 100 mg, 250 Tablets

What is Niacinamide (Vitamin B3)?

Niacinamide, also known as nicotinamide, is one of the forms of vitamin B3. This water-soluble vitamin is essential for the body, as it participates in more than 50 metabolic reactions, most of them enzymatic. Unlike niacin (nicotinic acid), niacinamide does not produce the characteristic skin flushing, making it an ideal option for those seeking the benefits of vitamin B3 without discomfort.

Source Naturals offers this supplement in a dosage of 100 mg per tablet, with 250 tablets per container, manufactured in the USA under strict Good Manufacturing Practices (cGMP) standards.

EFSA-backed benefits

The European Food Safety Authority (EFSA) has approved several health claims for niacin (including niacinamide). These claims are based on scientific evidence and are the only ones that can be legally used in the European Union:

• Energy metabolism: Niacin contributes to normal energy metabolism.
• Nervous system: Contributes to the normal functioning of the nervous system.
• Psychological function: Contributes to normal psychological function.
• Skin and mucous membranes: Contributes to the maintenance of normal skin and mucous membranes.
• Reduction of tiredness: Contributes to the reduction of tiredness and fatigue.

These effects are obtained with an adequate intake of vitamin B3, which can be supplemented with this supplement.

Niacinamide vs. Niacin: What's the Difference?

Both are forms of vitamin B3, but they have key differences. Niacin (nicotinic acid) can cause a temporary redness known as "flush" due to vasodilation. This effect is harmless but annoying for many people. Niacinamide, on the other hand, does not cause this redness, making it more suitable for daily use without discomfort.

From a functional point of view, both forms participate in the same metabolic reactions and provide the same EFSA-backed benefits. The choice between one or the other depends on personal tolerance and specific needs. If you want to avoid the flush, niacinamide is your best option.

How much niacinamide should I take per day?

The recommended dose in this product is 1 tablet per day, which provides 100 mg of niacinamide. This amount is within the safe and effective range for most adults. The reference intake for vitamin B3 in the EU is 16 mg per day, so this supplement provides a significantly higher amount, suitable for covering specific needs.

It is recommended not to exceed the daily dose without prior consultation with a healthcare professional. Very high doses (above 500 mg/day) can have adverse effects, although niacinamide is generally well tolerated.

Who should consider this supplement?

This niacinamide supplement is suitable for people who:

• Seek to support their energy metabolism and reduce tiredness.
• Wish to maintain the health of their nervous system and psychological function.
• Want to care for their skin and mucous membranes.
• Follow restrictive diets or have increased nutritional needs.
• Prefer to avoid the flushing associated with niacin.

As with any supplement, it is important to consult a healthcare professional before starting to take it, especially if you are pregnant, breastfeeding, or undergoing medical treatment.

Possible side effects and precautions

Niacinamide is safe and well-tolerated at recommended doses. However, at very high doses (e.g., more than 500 mg per day), it can cause mild digestive discomfort, headache, or dizziness. The flushing effect does not occur with niacinamide, unlike niacin.

The recommended daily dose should not be exceeded without medical supervision. This product is a food supplement, not a medicine, and should not be used as a substitute for a balanced diet and a healthy lifestyle. Keep out of reach of children. Store in a cool, dry place.
