📦 Did your vial ship from Olympia? It has a small metal center cap that needs to be removed before your first dose. See how to remove it (includes a short video).
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell that supports energy production, cellular repair, and healthy aging. Belle offers NAD+ injections as an add-on treatment. Patients typically report improved energy, mental clarity, and faster recovery within the first few weeks.
How it works: NAD+ helps your mitochondria convert food into energy and activates enzymes that repair DNA and reduce inflammation. NAD+ levels naturally decline with age, and injections offer a direct way to restore them.
Potential benefits: Cellular energy and vitality. Mental clarity and focus. Healthy aging support and DNA repair. Recovery and resilience.
Why pair NAD+ with GLP-1 medications: NAD+ complements GLP-1 therapy by supporting energy levels (reduces fatigue and brain fog common with GLP-1s), helping preserve muscle mass during weight loss, and optimizing fat metabolism.
Common side effects: Usually mild. See "NAD+ side effects and what's normal".
Who should not take NAD+: Do not use if you are pregnant or breastfeeding, undergoing active cancer treatment, or managing uncontrolled heart, liver, or kidney conditions.
