Review: Does the trick - Been using this since 2024 and this is my verdict on this Brand. Easy to swallow with no taste. Side effects are expected, the flush. Dosage of 100mg is a good start but I prefer 200mg is sufficient (I've gone all the way up to 500mg). Great value for the money, especially when compared to pharmaceutical prices.
Review: It's supposed to cause a flush that's how you know it's working - This is the good Niacin that all the positive research has results are based on. Read your supplement labels. Chances are high that your taking what's being sold as a Niacin substitute. If it doesn't make you flush it isn't working. If the flush is unbearable 1 start with a lower dose and work up to higher doses. 2 take after a meal on a full stomach. 3 expect a flush. If you're not getting at least some flush you're wasting your time, money and effort.

### ⭐⭐⭐⭐⭐ Effective Niacin Supplement with Flexible Dosing for Energy and Support
*by J***F on April 20, 2026*

I bought Nutricost Niacin (Vitamin B3) 100mg mainly as a morning supplement for energy, and it has been helpful overall. I’ve also noticed it seems to help with hangover recovery. Mood: I’ve noticed a mild improvement in overall mood and alertness when taking it consistently in the morning. Ease of Use: Very easy to incorporate into a daily routine. The capsules are simple to take and don’t require any special timing beyond my morning dose. Dosage: I usually take 2 capsules in the morning. About 90% of the time I don’t experience a flush at that dose. If I take 3 capsules, flushing happens about 50% of the time, and with 4 capsules it almost always occurs. It’s helpful to have that predictable response depending on dosage. Odor: No noticeable odor, which makes them easy to take. Energy: I do feel a noticeable boost in energy and alertness after taking it, especially in the morning. Pill Size: The capsules are a reasonable size and easy to swallow without issue. Overall, this is a solid niacin supplement that works well for energy support and general wellness. The flushing effect is there depending on dosage, but it’s manageable once you understand how your body responds.
