What are NAD+ injections?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of your body. It powers your mitochondria — the “batteries” that create energy and repair damage. NAD+ injections help restore declining levels, supporting energy, focus, recovery, and healthy aging.
How does the at-home NAD+ program work?
Start with a quick online consultation. If you’re a good candidate, your provider will prescribe a personalized NAD+ plan. Your kit — complete with pre-filled syringes, swabs, and instructions — is shipped straight to your door. You’ll self-administer at home, with unlimited provider messaging for guidance.
Who are the providers behind Shayk?
All providers are licensed healthcare professionals with clinical experience in NAD+ therapy and wellness medicine. Each one goes through a rigorous vetting process and is available for ongoing support throughout your treatment.
Do I need Insurance for NAD+ injections?
No insurance is required. We offer direct access and transparent pricing so you know exactly what you’ll pay upfront.
