Why cellular protection matters as you age
Cellular protection goes beyond antioxidants.
Two interconnected challenges as you age.
Oxidative stress, and the need to maintain a healthy inflammation response. Cell Shield is formulated to support both. Combining Setria® glutathione, Curcumin C3 Complex® and CellG8® liposomal vitamin C, it delivers targeted nutritional support for antioxidant defense, a healthy inflammation response and long-term cellular health.*
- 01
Helps maintain glutathione levels
Replenish your master antioxidant. Setria® is a patented, purified form of reduced glutathione. Clinical research has shown that regular supplementation can increase glutathione stores in the blood, supporting the body's natural antioxidant defenses. GlyNAC+ supports your internal production of glutathione; Cell Shield supports it via a different pathway.*
- 02
Supports a healthy inflammation response
Key support during aging. Curcumin C3 Complex® provides clinically studied curcuminoids that support a healthy inflammation response and cellular function.*
- 03
Supports cellular defense
Protect against everyday oxidative stress. Setria® glutathione works alongside CellG8® liposomal vitamin C and Curcumin C3 Complex® to support the body's antioxidant defense systems, helping protect cells against oxidative stress.*
- 04
Helps keep you moving
Stay active. Stay capable. One of the most important things as we age is to keep exercising to maintain physical function. Curcumin has been investigated for its potential to reduce inflammation associated with exercise and to help facilitate recovery.*

How to take it
Three capsules. Every evening.
Cell Shield delivers daily support for a healthy inflammation response and your body's antioxidant defenses, helping protect cellular health against the demands of everyday life, from training and travel to work and beyond.*
Step 1
Three capsules, evening
With water, with or without food. Keep it with your evening routine.
Step 2
Every day, no gaps
Glutathione returns to baseline when you stop, so consistency is the whole point.
Step 3
Stack it with GlyNAC+ and NAD Regen
GlyNAC+ supports your own glutathione production. Cell Shield supplies it by a different pathway.

Compare
Antioxidant protection is only part of the picture.
Healthy aging demands more than antioxidant support alone. Cell Shield combines patented Setria® glutathione, Curcumin C3 Complex® and CellG8® liposomal vitamin C to support a healthy inflammation response and cellular defense, with AstraGin®, which emerging science suggests supports absorption. All for under $2 a day.*

Questions
Before you decide.
Straight answers. If yours isn't here, contact us.
What is Setria® glutathione?
A patented, purified form of reduced L-glutathione made by Kyowa Hakko through fermentation. Glutathione is often called the body's master antioxidant. It is made naturally from amino acids, but stress, diet and age affect how much you keep on hand. Setria® has been shown in studies to help raise glutathione stores with regular supplementation.*
Why not just take NAC or vitamin C?
NAC is a precursor; it gives your body a building block, and that's the route GlyNAC+ takes. Cell Shield supplies glutathione itself in its reduced, bioavailable form, then adds Curcumin C3 Complex® for a healthy inflammation response and CellG8® liposomal vitamin C for antioxidant support, with AstraGin® for absorption.* The two are complementary, not either/or.
How soon will I notice anything?
Antioxidant support is quiet by design; most people notice it as feeling less dragged down by training, travel and long days rather than as a single effect. Glutathione levels return to baseline when supplementation stops, so judge it over 60 to 90 days of daily use.
Does Cell Shield stack with NAD Regen and GlyNAC+?
Yes, that's how we built it. NAD Regen supports NAD+ production and preservation, in the morning. GlyNAC+ supports your own glutathione production. Cell Shield supports antioxidant defenses and a healthy inflammation response by a different pathway, in the evening.*
How does the 90-day guarantee work?
Try it for up to 90 days from your order date. If it isn't for you, contact us and we'll refund what you paid for your first bottle. One bottle per product, per customer. Full terms.

Yes, anytime, with no fees. Skip a delivery, change your frequency or cancel from your account. Subscribers save 10% on every order and get priority dispatch so you never run out.

Orders ship within 24 hours from our fulfillment center in Wisconsin and typically arrive in 3 to 6 business days. Tracking is emailed as soon as it leaves.
