Your body makes it. After 30, it makes less of it every year.
Immunocal glutathione support works differently from any other supplement. It delivers Bonded Cysteine™ directly to your cells, giving your body what it needs to produce its own glutathione naturally from the inside out.

Immunotec Patents
79 patents don’t happen by accident. Here’s what they protect.
No other company on earth holds 79 patents for its ability to raise glutathione levels. Every patent represents decades of peer-reviewed science, independent validation, and a formula that has never been successfully replicated. That is not a supplement claim. That is intellectual property law.

Research and Studies
85+ independent clinical studies. Real results.
Immunotec has not paid researchers to say nice things about Immunocal. Every one of the 85+ published studies was conducted independently at universities and medical institutions around the world. The results have been replicated across multiple populations, age groups, and health conditions. That kind of validation cannot be bought.

What is glutathione and why do I need it?
Glutathione is your body’s master antioxidant, produced naturally inside every cell. It fights oxidative damage, supports immune function, assists detoxification, and helps combat premature aging. Low glutathione levels have been linked to over 100 health conditions. After age 30 your body produces less of it every year.
Who makes Immunocal?
Immunocal is made by Immunotec, a science-based direct sales company founded over 45 years ago and operating in 18 countries worldwide. Immunotec’s research into glutathione began at McGill University in the 1970s under Dr. Gustavo Bounous, making it one of the longest-running supplement research programs in history.
Does Immunocal ship worldwide?
Yes. Glutathione Sales ships Immunocal to the USA, Canada, and most countries worldwide through Immunotec’s global distribution network. Immunotec operates in 18 countries and ships from local warehouses where available to ensure fast and reliable delivery.
What are the different Immunocal formulas?
Immunocal comes in three formulas. Immunocal Classic is the original patented glutathione precursor for everyday immune health and wellness.

Immunocal Sport is the athlete-focused formula adding L-Citrulline, Beet Root, Tart Cherry, and Magnesium for maximum performance and faster recovery.
How is Immunocal different from other glutathione supplements?
Unlike oral glutathione supplements that break down during digestion before reaching your cells, Immunocal delivers Bonded Cysteine directly to your cells so your body can produce its own glutathione naturally from the inside out. This patented delivery mechanism is backed by 92 independent clinical studies and has never been successfully replicated by any other supplement in 45 years.
Can I try Immunocal before buying a full box?
Yes. Immunotec offers a 5-day trial pack so you can experience Immunocal before committing to a full order. The trial is available to customers in the USA and Canada. Visit the 5 Day Trials section of our shop to order yours. Keep in mind that it can take longer for glutathione levels to increase to a level that you can feel, depending on your particular health situation.
