Products & Ingredients
What is NMN and why do I need it?
NMN (Nicotinamide Mononucleotide) is a direct precursor to NAD+, a coenzyme your body uses for energy production, DNA repair, and cellular function. NAD+ levels decline by up to 50% between ages 40and 60 — which is why fatigue, slower recovery, and cognitive fog become more common with age. NMN supplementation is the most clinically validated way to restore NAD+ levels. Our NMN formula also includes Resveratrol and TMG for synergistic support.
What is Astaxanthin and what makes yours different?
Astaxanthin is a naturally occurring carotenoid from Haematococcus pluvialis microalgae — the most potent antioxidant ever discovered, estimated to be up to 6,000x stronger than Vitamin C in certain antioxidant assays. Unlike most antioxidants, it is both fat- and water-soluble, meaning it protects every part of your cell simultaneously. Our formula delivers a triple-strength 12mg dose — formulated with MCT oil to enhance bioavailability significantly compared to standard dry powder capsules.
What does NAC + Glutathione do?
Glutathione is your body's master antioxidant — it neutralizes free radicals, supports liver detoxification, and has been clinically shown to brighten and even skin tone by inhibiting excess melanin production. By age 40, glutathione levels can decline by 30–50%. NAC (N-Acetyl Cysteine) is the most effective way to restore intracellular glutathione levels. Together, they provide comprehensive detox, brightening, and cellular protection.
What is Hyaluronic Acid doing internally?
Hyaluronic Acid (HA) holds up to 1,000x its weight in water and is the body's primary hydration molecule for skin, joints, and connective tissue. HA production declines significantly after age 25. Oral HA has been clinically shown to improve skin hydration, elasticity, and smoothness — while also supporting joint lubrication and gut barrier integrity. Topical HA only reaches the surface; oral HA reaches the deeper dermis and joint tissue.
Are your products suitable for vegans?
Our NMN and NAC + Glutathione formulas are vegan-friendly. Our Astaxanthin is encapsulated in a softgel with MCT oil — the softgel casing is derived from gelatin (not vegan). Please check individual product pages for the most current casing details.
Are your products third-party tested?
Yes. Every Eon Cellular product is manufactured in an FDA-registered, cGMP-certified facility and independently verified through third-party laboratory testing for purity, potency, and safety. We are also NSF Certified.
Dosage & Timing
When should I take each supplement?
For best results — NMN: Morning, with or before breakfast (NAD+ production aligns with morningcircadian metabolism). Astaxanthin: Morning, with your largest meal (fat-soluble, requires dietary fat —can increase bioavailability up to 12x). NAC + Glutathione: Morning, on an empty stomach or 30 minutesbefore food. Hyaluronic Acid: Morning or evening with food — consistency matters more than timing.
Can I take all four supplements together?
Yes — in fact, this is exactly what we recommend. The four formulas in the Eon Cellular stack aredesigned to work together synergistically. NMN activates the sirtuins that boost the body's ownglutathione production. Astaxanthin protects the mitochondria that NMN energizes. Hyaluronic Acid benefits from the hydrated cellular environment created by the full stack. They amplify each other.
How long until I see results?
Most customers notice initial improvements in energy and skin hydration within 2–4 weeks. Visible skin changes (tone, elasticity, brightness) typically become apparent around weeks 6–8. The full cumulative benefit of the stack — including joint health, epigenetic aging markers, and deep cellular changes —compounds over 3–6 months of consistent daily use.
What dose of NMN should I start with?
We recommend beginning with 250mg per day and increasing to 500mg after 2–4 weeks if well tolerated. Most clinical studies showing significant benefits use 250–500mg daily.
Can I take these with my existing medications?
Please consult your healthcare provider before starting any new supplement, especially if you are takingprescription medications. NAC may interact with certain medications including nitroglycerin and someblood thinners. NMN, Astaxanthin, and Hyaluronic Acid are generally very well tolerated — but your doctor knows your individual health picture best.
Are these safe during pregnancy or breastfeeding?
We recommend consulting your OB-GYN or healthcare provider before taking any supplements duringpregnancy or breastfeeding. As a precaution, we do not recommend these products during pregnancy or while nursing without medical clearance.
