"Glutathione is the body's master intracellular antioxidant and a central substrate for phase II detoxification. Intranasal delivery is one of the few routes shown by imaging to measurably elevate brain glutathione levels, and subcutaneous administration offers a practical alternative to IV for systemic support.

WHY GLUTATHIONE

Oxidative stress damages cells. Glutathione can help neutralize it.

HOW GLUTATHIONE WORKS

Defends cells against damage.

Glutathione is the most abundant antioxidant in the brain. It neutralizes free radicals to help prevent oxidative damage. Glutathione levels naturally decline with age.

Helps neutralize free radicals

Glutathione donates electrons to reactive oxygen molecules, disarming them before they can damage DNA, proteins, and cell membranes.

COMMON QUESTIONS

Questions, answered

What is glutathione?

Glutathione is a naturally occurring antioxidant produced in nearly every cell of the body. It plays a role in reducing free radical damage and supporting detoxification and immune function. Declining glutathione (GSH) levels are one of the most consistently observed biochemical changes associated with the aging process.

How do you take glutathione?

Inject glutathione (Injections) into the muscle or skin one to two times a week (for 200mg) or every other day (for 100mg).

For glutathione (Nasal Spray), spray once into each nostril one to two times daily.

What are the side effects of glutathione?

Long-term glutathione use has been linked to lower zinc levels. 

Who shouldn’t take glutathione?

Not recommended for people who are pregnant or breastfeeding. People with pre-existing kidney disease should avoid high-dose glutathione. Your doctor will evaluate whether glutathione is appropriate for you.
