Features

  • HELP SUPPORT SKIN CELLS HEALTH - Genex Formulas offers Flush Free Nicotinamide. Niacinamide supplement is a form of vitamin B3 (niacin) that can help support your bodys natural response to skin blemishes by supporting the skins natural ability to regenerate a smooth outer layer clear of blemishes, red spots, bumps, and warts. It also helps maintain healthy skin by promoting cell growth. Niacinamide offers you versatility for any skincare & any skin type.
  • HELPS SUPPORTS BODY STRENGTH - Vitamin B3 will help you to metabolize energy correctly. Nicotinamide plays an important role in transforming the food you eat into usable energy and helps your body cells carry out essential chemical reactions. Since Niacinamide is water-soluble, your body does not store this vitamin, which is why you need to eat Niacinamide daily. It also helps provides strength to your bones & relieve joint pain.
  • HELPS PRODUCE KERATIN - Niacinamide helps produce keratin, a form of protein that keeps your skin firm and healthy. Niacinamide can help your skin grow a ceramide (lipid) barrier, which can help to retain moisture. Niacinamide also plays a vital role in improving hair health. It increases the appearance, texture, and feel of hair even when they are chemically or physically damaged. Its circulation-supporting properties are suitable for all hair and skin types.
  • DIFFERENT FORM OF VITAMIN B3 - Nicotinamide is a different form of vitamin B3 to nicotinic acid or niacin, not to be confused with Niacin. Niacin, on the other hand, can cause flushing of the skin or skin flushing. Skin flushing means the feeling of warmth with rapid reddening of your neck, upper chest, or face. Flushing may happen because of increased blood flow. Preliminary evidence suggests that nicotinamide may support the bodys natural ability to support healthy joint mobility and comfort.
  • SATISFACTION GUARANTEED - Nicotinamide 500 mg is Flush free form of Niacin. Genex holds itself to a higher standard, selling only quality supplements manufactured with tested and trusted ingredients.

  • Prevents skin cancer!
Size: 100 Count (Pack of 1)
I have very fair skin and would regularly need to have pre-cancerous lesions frozen during visits to my dermalogist. I started taking these daily a few years ago and have seen a MAJOR decline in these lesions. My last two doctor visits have resulted in nothing needing to be frozen. The person who recommended these to me has had the same results. ... show more

  • It works
Size: 100 Count (Pack of 3)
My dermatologist wanted me to try these, saying that it would cut down on basal cell and squamous cell skin cancers. And he was right. I still get some because I am immunosuppressed as the result of a kidney transplant, but I have been surprised to see various skin problems disappear. I know that it was the nicotinamide because when I ran out once, after a week, skin problems started to appear again, but once I started taking these again, they cleared up. ... show more

  • Works great gives me energy boost!
Size: 100 Count (Pack of 1)
I take 2 capsules every morning. Started taking this after the NMN FDA ban. For now it's a suitable enough replacement for NMN for the energy I need. However I need (2) 500mg capsules to feel similar energy as (1) 500mg NMN capsule
