OPITAC® — L-Glutathione‡
The tripod of ingredients delivered in GlutaQ® work in unison to help coordinate the body’s immune system, encouraging a healthy cell cycle to help maintain your cellular health and function.
OPITAC® (Reduced Glutathione‡)
Glutathione, an important molecule naturally produced in the liver and various tissues throughout the body, acts as the cells’ natural garbage man by helping to identify toxins within the body’s cells and converting them so they can be metabolized and expelled from the body. Because glutathione is the master antioxidant in the body and is heavily concentrated in tissues such as the liver, lungs, heart and skeletal muscle, it plays a critical role in supporting immune function and protection against oxidative stress.

The Key to Graceful Aging
The combination of ingredients (quercetin, reduced glutathione and beetroot) in GlutaQ® constructs the optimal scenario for promoting cell health, glutathione synthesis and support of the immune system. Together these ingredients help support healthy mitochondrial activity, which can impact our cells’ response to glucose and our cognitive and neurological health. While many age and cellular-related benefits are attributed to the unique mix of antioxidant-supporting ingredients in GlutaQ, the real benefit is where these antioxidants function best, inside the cell. Glutathione is an intracellular antioxidant — helping to neutralize free radicals that contribute to aging.

Frequently Asked Questions
How does this supplement support the mitochondria to the cell?
Mitochondria, often referred to as the cells’ “powerhouse” or “engine,” delivers energy (ATP) to all cells in the body, except red blood cells. Every cell requires ATP to function properly. For example, ATP provides us with the stamina needed to maintain endurance during physical activity. As we age, the mitochondria within our cells naturally begin to decline in both quantity and quality of performance. Their ability to carry out the same function or at the same intensity may diminish with age, poor physical fitness and an unhealthy diet. GlutaQ® helps support the delivery of nutrients to the mitochondria in our cells to maintain healthy mitochondrial function and ultimately promotes cell longevity by allowing the cells to hold on to oxygen longer.
Are there any side effects associated with taking quercetin as an oral supplement?
Mild side effects associated with oral supplementation of quercetin are tingling of the limbs and possible headache. It is uncertain if long-term supplementation of quercetin may have side effects.
Is GlutaQ safe for those who have or may be prone to kidney issues?
Supplementation of quercetin above the recommended supplementation intake may be associated with the way the liver metabolizes other medications and/or kidney issues. While it has been found that consuming excessive amounts of beets may have effects on the kidney, there is no substantial evidence suggesting harmful effects on the liver from supplementation of beetroot powder.
Are there any drug interactions associated with GlutaQ?
If you are currently using any other prescription drugs, have an ongoing medical condition, or if you are pregnant or breastfeeding, consult your health care provider before using this product. Do not use this product if you are allergic to any of the ingredients. Do not use if the safety seal is broken or missing.
What other supplements would pair well with this product?
This formula would pair well with Isotonix® Bromelain Plus and Isotonix Vitamin C, which both work to support a healthy immune system. Quercetin is known to have a low bioavailability, meaning it is not easily absorbed by the body. However, findings report that taking quercetin along with vitamin C and/or bromelain may help the body to absorb quercetin and its benefits more effectively.
What additional benefits may glutathione provide?
Research shows that supplementation of glutathione may also support cognitive health.

I started using Isotonix® Glutathione (Gluta-Q) because I wanted extra nutritional support for my overall wellness and metabolism.
What I like most is knowing that glutathione is known as a powerful antioxidant that helps support the body’s natural processes and overall metabolic health. It is great knowing I’m giving my body support at the cellular level.
For me, Isotonix Gluta-Q has become a simple daily habit that helps me stay consistent with supporting a healthy metabolism.
