Your cellular shield: Glutathione is a tripeptide composed of glutamine, cysteine, and glycine—found in every cell of your body. As the master antioxidant, it neutralizes free radicals, recycles other antioxidants like vitamins C and E, and regulates critical cellular processes including DNA synthesis, immune response, and detoxification pathways.
Why supplementation matters: Your glutathione levels plummet by 50% between ages 45 and 80, while chronic stress, pollution, and poor diet accelerate this decline. Low glutathione directly correlates with oxidative damage, accelerated aging, compromised immunity, and increased disease risk. Oral supplements face a cruel irony—stomach acid destroys 99% before absorption. Injectable glutathione bypasses this barrier entirely, flooding your cells with this protective molecule and reversing years of depletion within weeks.
Injectable glutathione achieves 100% bioavailability, while oral glutathione is almost entirely destroyed by stomach acid (less than 1% absorbed). This means you need 100x the oral dose to match one injection.
Chronic fatigue syndrome, autoimmune conditions, Parkinson's disease, liver disease, and general aging all show documented improvements. Athletes use it for recovery, while others seek immune support.
The most common side effect is mild irritation at the injection site lasting 5-10 minutes. Serious adverse reactions are extremely rare (less than 0.1% of patients).
Glutathione levels remain elevated for 2-4 weeks after stopping injections, then gradually return to baseline over 4-6 weeks. Most patients choose ongoing monthly maintenance.
While glutathione is naturally present in the body, injectable supplementation during pregnancy or breastfeeding hasn't been studied. We recommend waiting until after breastfeeding.
Yes, NAD+ requires a prescription from a licensed physician. RenuviaRX's telehealth platform connects you with board-certified doctors who can prescribe NAD+ if medically appropriate. The consultation comes for FREE within our subscription package.
Both support cellular health but work differently. Glutathione focuses on antioxidant protection and detoxification, while NAD+ targets energy production. Many patients use both.
Most patients start with weekly injections for 4-6 weeks, then transition to monthly maintenance. Athletes may increase frequency before competitions.
We analyzed 200+ peer-reviewed studies to bring you evidence-based NAD+ therapy. Here's what the research proves.
