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.

Our dog loves them
Style: Latex Surpise Color, Size: 6"
Not for every type of dog, but our dog LOVES these things. Try one and see how it goes. They are cheap, so no great loss if your dog doesn't like it, But if it does, you'll have a great time with them. Best $3 I could spend

Tie a Knot in it if it rips
Style: Plush Surprise Color, Size: 6", Style: Plush Surprise Color, Size: 6"
My puppy split the middle belly seam in about 5 minutes of spirited play with the white foam and squeak assembly scattered about, but he loves these loofa toys - goes nuts for them. Went through a couple of the little $3 ones so I tried this big one which he ripped apart. But I tied a knot in the middle of it over the ripped part and guess what, it's better than before. He loves the whipping the big knot around. The part where it ripped was where they filled it I think but the rest of the stitching is really quite solid. Takes a beating, to a point. The little ones lasted a reasonable time before they were totally played.

Not the most durable, but my dog LOVES it.
Style: Plush Surprise Color, Size: 24"
My boyfriend’s dog had the small version from Petsmart and she has been very gentle with it since she likes it so much. I decided to surprise her with this 24 inch one for Christmas. She was obsessed! It’s cute, it’s very soft, and has a big squeaker in the top, which she loves! She was a little more tough on it and it did get some rips 12 hours in, but it is still in one piece at the moment and brings lots of joy. The dog is a medium/large size. Dog toys can be so expensive. I personally think the was a great price despite not being the most durable. I may purchase again next year!

Update: Excellent Customer Service Made Everything Worthwhile!
Style: Plush Surprise Color, Size: 24", Style: Plush Surprise Color, Size: 24"
07/17/2025: This doggy toy was destroyed within 2 hours of its arrival. In my opinion, it was not at all worth the cost. (1 star) Update (07/19/2025): I have contacted the manufacturer and they said they will send out a new replacement toy. As of now, I have revised the review to 2 stars for the excellent and efficient customer service pending arrival of said replacement. Will update again soon. (2 stars) Update (07/23/2025): The replacements have arrived! My dog loves the new plushie sloth and so far it is in tact. It doesn't have stuffing in the body as far as I can tell, so little to no clean up hopefully. They also sent her a spiked squeaky ball and she's getting used to it. This company has some of the best customer service and support that I've experienced. (5 stars)
