SAVE 50-70% TODAY →Why Choose LIFINITY NAD+ Injections?
Maximum Bioavailability
Injectable NAD+ achieves near 100% bioavailability by bypassing digestive breakdown entirely. Oral supplements lose over 90% of NAD+ through digestion, delivering only a fraction of the dose to your cells. [1]
Strength Dosing
Medical-grade 200mg/mL concentration in 6mL vials (1200mg monthly)—not underdosed pills. Supervised by licensed physicians.
Science-Backed Protocol
Our dosing protocol is based on peer-reviewed research showing optimal cellular NAD+ restoration. [2]
Best Value Guarantee
Get pharmaceutical-grade NAD+ therapy for 50-70% less than competitors. No hidden fees, no insurance headaches.
Real Patients, Real Results
"Had a crazy week at work and the NAD+ shots actually helped me get through it. Usually I'm dead by Wednesday lol."
"My friend recommended NAD+ and I was skeptical tbh. But wow, I actually have energy to work out after work now. Still early days but so far so good."
"Been doing NAD+ for about 3 months now, not sure if its placebo but I definitely feel less tired I used to crash at 2pm every day and now I don't."

The Science of NAD+
Evidence-Based Therapy, Not Marketing Hype
NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme found in every cell of your body. Research shows NAD+ levels decline by up to 50% by age 50, contributing to cellular aging, decreased energy, and cognitive decline.
Injectable NAD+ therapy delivers therapeutic doses directly to your bloodstream, bypassing the over 90% degradation that occurs with oral supplements. Clinical studies demonstrate significant improvements in:
- Cellular energy production and ATP synthesis
- DNA repair mechanisms and cellular health
- Mitochondrial function and efficiency
- Cognitive performance and mental clarity
- Metabolic health and longevity markers
Our 1200mg monthly protocol provides clinically effective dosing based on the latest research, ensuring optimal NAD+ restoration without the premium pricing.
