Perfect dose

I also tried 500mg Niacin, but it turned my father scary red, turned my mom itchy and it made me dizzy. I also tried a bigger dose of No flush Niacin but it made me dizzy and gave me a headache. This one just makes me pink, without side effects. PS: it is extremely important to stay away from alcohol, spices and vitamin C, the day you take Niacin, better yet avoid any other supplements.

Great Energy Boost

This niacin supplement works great! I take it in the morning, and my energy levels are better. It's really effective for my health, like keeping cholesterol normal and improving blood circulation. The tablets are small, easy to swallow, and can be broken if needed. Natural Factors makes it with good ingredients, no extra stuff. Plus, the price is reasonable for what you get! Some people feel a warm flush when taking it, but I think it's helping my body by increasing blood flow. Highly recommend this product!

Reliable and effective supplement

I’ve been using this niacin supplement for a while and find it consistent and effective. The 100 mg dose is a great starting point if you’re sensitive to the niacin flush. It helps support my energy levels and general well-being. The tablets are small and easy to swallow. Natural Factors is a brand I trust, and I appreciate the clean ingredients with no unnecessary fillers. Highly recommended for anyone incorporating niacin into their routine.

A Decent Niacin option!

I purchased this together with another Niacin product from Source Naturals primarily for my dad to support normal level of cholesterol and to improve overall health. I also used it for the purpose of hair support. It definitely gives a nice flush, which is totally expected from Niacin. I'm quite satisfied!

Great quality and ingredient potency

I could definitely feel the effect with just 1–2 tablets. The quality and ingredients are great, and taking it provides a noticeable boost in energy. The size is convenient to swallow, and the packaging arrived in perfect condition. I will definitely buy this product again!

Nice flush but no need for it

i was expecting energy support from Niacin but except a strong flush and getting extremly tired, it have not seen a gain in energy, even combining it with other supplements.

Awesome

I’ve been taking this niacin supplement for about two months now and it’s made a real difference - I started using it to support my cholesterol and overall cardiovascular health, and my most recent bloodwork showed a noticeable improvement in my HDL levels. What I appreciate the most is that there are no unnecessary filler ingredients that might do more harm than good - will stick to this brand from now on.
