A sublingual spray combining Glutathione 100mg, Nicotinamide (NAD+ precursor) 50mg, and Inositol 100mg to support antioxidant defense, cellular energy, and immune health. A daily oral maintenance option for anti-aging, longevity, and IV therapy-adjacent wellness protocols.
GlutaTonic™ combines three cellular health nutrients — Glutathione, Nicotinamide (a NAD+ precursor), and Inositol — in a sublingual spray format for daily maintenance support. For anti-aging and longevity practices offering injectable Glutathione or NAD+ protocols, GlutaTonic provides a practical between-visit oral option patients can use at home to maintain cellular antioxidant and energy support between in-office treatments.
For more on NAD+ and cellular aging, see the Anti-Aging White Paper.
Each 12 sprays contains:
| Ingredient | Amount |
|---|---|
| Glutathione | 100 mg |
| Inositol | 100 mg |
| Nicotinamide (NAD+ precursor) | 50 mg |
Suggested use: 12 sprays daily under the tongue, or as directed by the ordering provider.
Glutathione (100mg): The body’s primary cellular antioxidant, present in every cell and responsible for neutralizing free radicals, supporting immune function, and regulating cellular metabolism. Glutathione levels decline with age, illness, and certain medications. Sublingual delivery improves absorption compared to oral capsules by bypassing first-pass metabolism in the liver — relevant for a molecule that degrades significantly during standard oral digestion.
Nicotinamide as NAD+ Precursor (50mg): Nicotinamide (NAM) enters the NAMPT salvage pathway — the primary route of NAD+ biosynthesis in the body. NAD+ activates sirtuins, the enzymes associated with mitochondrial biogenesis, DNA repair, and cellular stress resilience. NAD+ levels decline significantly with age, and Nicotinamide provides a practical oral precursor option alongside injectable NAD+ therapy.
Inositol (100mg): Supports brain cell membrane integrity and healthy neurotransmitter signaling. Inositol also plays a role in cellular glucose uptake and may enhance Glutathione’s antioxidant activity — a supporting role that makes it a natural companion to both the antioxidant and energy metabolism components of this formula.
GlutaTonic is best understood as the daily oral maintenance layer alongside injectable protocols. Glutathione injections and NAD+ injections provide acute, high-concentration therapeutic delivery. GlutaTonic provides consistent daily support between injection visits — a practical way for practices to extend the clinical value of their injectable programs and improve patient compliance between appointments.
Providers who carry GlutaTonic often round out the protocol with:
Glutathione Injection — GlutaTonic delivers daily oral Glutathione maintenance between in-office injection visits, extending the antioxidant support window for patients on injectable Glutathione protocols.
NAD+ Injection — Nicotinamide in GlutaTonic feeds the same NAD+ biosynthesis pathway as injectable NAD+ — a natural oral companion for patients receiving periodic NAD+ infusions who want daily precursor support between sessions.
Niagen® (NR) Injection — For practices using Nicotinamide Riboside as their NAD+ precursor injectable, GlutaTonic’s Nicotinamide adds additional NAD+ precursor coverage through the parallel NAMPT salvage pathway.
How does sublingual delivery improve Glutathione absorption?
Glutathione taken orally is largely degraded in the digestive tract before reaching systemic circulation. Sublingual delivery absorbs directly through the mucosal membrane under the tongue, bypassing first-pass liver metabolism and significantly improving bioavailability compared to standard oral capsules.
What is the suggested use?
12 sprays daily under the tongue, or as directed by the ordering provider.
How does GlutaTonic fit alongside injectable Glutathione and NAD+ protocols?
GlutaTonic is the daily oral maintenance layer — injectable protocols provide acute therapeutic concentration, GlutaTonic provides consistent daily support between visits. The two approaches are complementary rather than competing.
Can GlutaTonic be private labeled under our practice brand?
Yes. Minimum order is 24 bottles with a design proof ready within 2–3 business days. Contact our team to get started.
