Too Powerful!

I used 1 gram and my whole face and neck became red for almost an hour, I recommend taking 100 mg and testing then slowly increasing the dose to see if you're comfortable with it.

Excellent quality, detox flush and energy boost

I recently tried this niacin supplement, and I’m blown away by the quality! It’s hands-down the best form of niacin I’ve used. The powder is easy to take, and the results are excellent—delivering a powerful flush that’s perfect for detoxing. Within days, I noticed a significant boost in energy, leaving me feeling revitalized and sharp. The flush, while intense, is a clear sign it’s working, and I love how it supports my overall wellness. The product is straightforward to incorporate into my routine, with no complicated instructions. If you’re looking for a high-quality niacin supplement that’s effective and reliable, this is it. I can’t recommend it enough for anyone wanting to enhance their energy and detox naturally. A top-tier choice that truly delivers!

Pleasantly surprised

The quality is really good! It is quite unbelievable! U do get a flash but now it ia going away. Nice big size too and it gives great energy. The taste is a bit weird but it’s no problem for me. Highy recommended. Yes it is a good thing to try so I will recommend.

Excellent, proceed with caution

I am very happy with the quality of this niacin and that it's dissolvable in water. I took the full dose initially despite not taking niacin before and experienced an intense niacin flush. I'm now building it up more slowly and my body is adjusting to the flush. All in all, excellent, and it's great value for money.

Good product

Great for improving blood flow to the skin. Feels like it solved some skin problems caused by weak blood circulation. Fast working within 10 minutes. Causes flushing which can be one of the desired/undesired effects dependent on the person. Good packaging, the included spoon is exactly 1g of niacin.

Powerful high dose of Niacin

Highly recommend by my close friend. He recommended me to take this to lower my LDL and for better blood circulation. I like the quality of it and pure ingredient without any frill. For the first week I took full dose 1000mg and I really love the flushing effect. My whole body got red and itch. After the first week I reduced to half dose as I am afraid it will damage my liver as I am taking B- complex also. Taste wise is very fine for me. it is tasted alittle sour.

Excellent

I like this product because the powder is free of additives, niacin is the only ingredient. It dissolves well. It takes effect quite quickly. Great price for this package. Very good quality. It has a strong niacin flush effect at 500 mg potency. Sour taste, but tolerable. I recommend the product.
