Research-Supported Benefits:

Supports Cellular Health. A non-flushing form of vitamin B3, niacinamide is an antioxidant and NAD+ precursor that supports DNA repair and sirtuin activation. Niacinamide is an antioxidant, which fights oxidative stress and helps to repair DNA. (1)

Supports Energy Levels. Niacinamide is readily absorbed in the stomach and the small intestine, where it can be subsequently transported to tissues for the synthesis of NAD+ to help produce energy. (2)

Supports Skin Health. Niacinamide supports skin health through its actions as an antioxidant. It also increases the production of skin ceramides—healthy fats that strengthen skin barriers and lock in moisture—and boosts collagen production. (3)

Supports Joint Health. Niacinamide supports a healthier inflammatory response in the joints and boosts collagen production, leading to more flexibility, mobility and comfort. Research shows that adults with joint disorders who took niacinamide for 12 weeks had improved joint health by almost one-third compared to the control group. (4)

Supports Brain Health. Niacin deficiency is known to cause serious brain damage. Research suggests that niacinamide may be beneficial for protecting and supporting brain health and cognitive function with age because it protects against neuron damage and boosts NAD+ levels. (5)

  • Niacinamide vs. Niacin. Compared to other companies that typically use niacin, ProHealth Longevity uses niacinamide because the body doesn’t have to do extra work to convert niacin into niacinamide.
  • Doesn’t Cause Skin Flushing. Plus, high doses of niacinamide don’t cause skin flushing, like high-dose niacin products tend to do.
  • High Dosage. ProHealth Longevity’s Flush-Free Niacinamide contains 600 mg of niacinamide (as nicotinamide) per serving, which is 3,750% of the Daily Value for niacin. Competitors typically contain 500 mg.
  • Quality Manufacturing Practices. All of our products are manufactured in an FDA-registered, GMP-certified facility.
  • Third-Party Tested in the USA. Every batch is third-party tested in US laboratories to ensure the highest quality, purity and potency. Certificates of Analysis are available.
A non-flushing form of vitamin B3, niacinamide is an antioxidant and NAD+ precursor that supports DNA repair and sirtuin activation.

Actually feels cool at night
Color: Light Gray, Size: Standard
I’ve been using these for several days now and I did notice a difference. I tend to get hot while sleeping, so I was curious if they would actually help, and they do feel cool when you lay on them. I also like that they’re soft and comfortable, not that weird texture some “cooling” products have. So far, I’ve been really happy with them.

Cool, Comfortable, and Worth Every Penny!
Color: Light Gray, Size: Standard
I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face. I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness. If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!

Extremely cold, silky, gentle on hair
Color: White, Size: Queen
This was so cold when I removed it from the package that at first I thought it would be too cold. It was as if it had been in a freezer. I really like how silky it is on my face. (I can't stand a rough feeling pillowcase.) It is also gentle on my curly hair. The pillowcase can warm up from being slept on, but a shift of just a few inches gets back to wonderful cold. I highly recommend this as an extremely cool, silky smooth fabric. These are much colder than my very expensive miracle sheets.

Freaking Amazing 🤩
I never write reviews but these pillow cases absolutely deserve one!!! These are absolutely amazing! So soft and cool! I sweat so bad every night!! I wake up and my hair, shirt and pillow are drenched!!! I slipped these bad boys on as soon as they came in, and let me tell you! They were cold to the touch, I woke up this morning and I wasn’t sweating! I thought $20 something dollars was a little expensive for 2 pillow cases but was totally worth it! We love love love them!🩷🩷🩷Hubby approved😉

Stretchy Material and Cooling Fabric
Color: Light Gray, Size: Standard, Color: Light Gray, Size: Standard
Material: is very stretchy and cools well. It has a zipper which is good because the fabric is very soft and slippery and if it didn’t have a zipper the pillow would not stay in the case. Durability: zipper works great and material is easy to clean. Color: I have the gray and my daughter has the pink. Both colors as advertised. Value: Good value and I got what I expected.
