Works

I took B3 because I have the beginnings of polyneuropathy. The first pill gave me the side effect that is written on the package. Redness of the ears, face and neck, the second tablet, like the others, did not have these side effects. After a week, I feel that the microcirculation is better. I will continue to drink until I drink all 250 pieces. tsblets are white without taste or smell. Please consider that we are supporting each other by giving our reviews a thumbs up 👍.

Attention! Very high concentration

Packaging for the whole family. It is worth considering the very high concentration and possible unwanted effects. Try carefully (the capsule can be divided into several parts). Perfectly helps blood circulation and blood vessels.

NOW Foods, Niacin, 500 mg, 250 Tablets

Niacin (Vitamin B3) is a water-soluble vitamin that plays a key role in energy production by helping convert food into usable energy. It supports healthy skin, nervous system, and digestive system function. Niacin is also known for its ability to improve cholesterol levels by increasing "good" HDL cholesterol and lowering "bad" LDL cholesterol. It can be found in foods like meat, fish, and whole grains, or taken as a supplement to support cardiovascular health and overall well-being.

caution : heart beats real fast the whole day, though me heart beats are usually slow like 76 per minute slow.....

caution : heart beats real fast 30 minutes after intake then for the whole day so it must be quite effective and potent, though me heart beats are usually slow like 76 per minute slow, so beware and take half on the first few try ^_-

No flushing

No niacin flushing in my face, only my legs where I get lymphatic drainage issues. The tablet has a quality coating, so it did not break down on my tongue or have any notable taste as I was trying to swallow. I experienced a slight feeling of reflux, but again, I am susceptible to that normally. The size of the tabl

Skin health

I love this product. I use for my skin that needs niacinamide. Niacin is the pre-stage of niacinamide and processed by our body to produce niacinamide.

Good quality

My doctor recommended that I buy this product, so I bought it. I was happy with the price and size of the package. I don't really know what it was supposed to do, so I can't tell if it was potent, but the pills were gentle on the stomach.

Potent Dose for Reliable B3 Support

This 500 mg niacin offers a strong, straightforward dose of vitamin B3. The tablets are compact and easy to take, and I appreciate the simple, no-frills formula. I’ve only been using it for a short time, so it’s early to notice major changes, but it feels like a solid way to support overall energy metabolism and circulation. A good value if you’re looking for high-potency niacin in tablet form.
