I've been only brave enough to take the once a week. They are way more stronger than all other previous niacin products of the same dosage I've used previously. I have about 40-60 mins of heavy flushing across my body with one tablet. Not for the feint hearted.

Large portion and powerful effect. I use it when I need a stronger effect (fatigue, colds, acute sinusitis, insomnia). At my modest weight it causes me drowsiness, so I take advantage of this effect and use it for a healthy sleep. Large portion and powerful effect.

The thermal effect is strong, so you have to be able to tolerate it.

I've been suffering from long covid during the last two years, I've been taking Niacin for about one year and a half and had good results as it is improving my fatigue, brain fog and digestive issues. I take between 3 to 6 capsules a day, it used to be expensive with other brands, but this one is way more affordable for the same results. I can only recommend it!

I am very happy with this product. My brain fog is gone, my energy is back, I feel like a completely different, happy person. Thanks Herb!!!

Quality is super! The ingredients are great! Size arranged! What you need! Performance is felt! the product arranged, perfectly packed, the effect is definitely there! I will order more! Just as quickly delivered

Excellent quality! Trusted brand! High potency!Big size! I like the flush effect!

Great value vs other products I looked at, and based on the "flush" feeling it is having the desired effect. One of the rare supplements you can immediately feel do something

I had severe reaction towards Niacin that's why i stopped taking it but the price is extremely good and there is no after taste. it definitely gave me some energy.

Large amount and easy to swallow. Niacin is a good helper for the cardio system.
