What is NAD+?

NAD+ (Nicotinamide adenine dinucleotide) is a coenzyme that plays a crucial role in various cellular processes, including energy metabolism, DNA repair, and cellular stress response. NAD+ levels decline with age, and supplementation with NAD+ has been shown to have beneficial effects on health and longevity.

How does NAD+ work?

NAD+ is found in every cell in your body and is essential for creating cellular energy and maintaining cellular health. NAD+ helps to regulate the body's energy production by stimulating the production of ATP, the body's primary source of energy. In the body, NAD+ is primarily stored in the mitochondria, which are the powerhouse of the cells responsible for producing energy.

I can’t say enough good things about Kate! She was incredibly knowledgeable and supportive throughout the entire process. I had so many questions and was feeling really hesitant about starting my weight loss medication, but Kate took the time to explain everything clearly and thoroughly. She made sure I felt confident and fully informed before moving forward. Her guidance and encouragement made all the difference. Truly the best — I’m so grateful for her help!

I am a new client with ReadyRX. The experience has been great so far. The shipping was quick and easy. They reached out by phone the day after I received my prescription to see if I had any questions or concerns. They have been very thorough and informative through this process. There are numerous options available but I would definitely recommend ReadyRX.

As a busy executive, I have little free time in my day. I was skeptical about injections, but the convenience of home administration and the immediate results had me convinced to try. No more afternoon crashes - just sustained energy. It’s been an incredible experience so far!

Coming from someone who switched from a different company, I can not recommend READYRX enough! Their customer service is beyond accommodating and their processing times are quick. I’ve never felt more confident than I do now and in a short 4 weeks I’m down 10 pounds! I highly suggest if you’re contemplating the lifestyle change to work with READYRX! You won’t be disappointed

Can NAD+ help prevent Alzheimer's disease?

While research into the potential benefits of NAD+ for Alzheimer's disease is still ongoing, some studies suggest that NAD+ supplementation could have therapeutic potential in preventing or mitigating aspects of the disease. In this study, the researchers investigated the effects of NAD+ supplementation in a mouse model of Alzheimer's disease with impaired DNA repair mechanisms. They found that NAD+ supplementation normalized several Alzheimer's-related features, including synaptic plasticity, learning and memory deficits, and DNA damage responses.

NAD+ injections are available as 500mg and 1,000mg per month vials, as well as 4,500mg nasal sprays. The dosing for NAD+ varies depending on the individual patient and the specific indication for which it is being used. NAD+ should only be taken under the guidance of a healthcare provider.
