What Is Glutathione? The Body's Master Antioxidant, Explained

Glutathione is often called the body's "master antioxidant," and it's a staple in many longevity and wellness routines. Here's a clear guide to what it is and how people use it.

What glutathione is

Glutathione is a small molecule made from three amino acids: glutamine (as glutamate), cysteine and glycine. Your cells make it themselves, and it's found in nearly every cell in your body, with especially high levels in the liver.

What it does

Antioxidant protection

Everyday life, from exercise and sunlight to normal metabolism, creates reactive molecules that put cells under oxidative stress. Glutathione helps neutralize them and also helps recycle other antioxidants such as vitamins C and E, so they can keep working.

Cellular maintenance

Glutathione supports the liver's normal processing of compounds the body needs to clear, and it plays a role in healthy immune function.

Why people supplement it

Glutathione levels are influenced by age, diet, sleep, alcohol, intense training and stress. Many people add it to their routine as part of a healthy-aging or recovery plan, often alongside NAD+.

How to take glutathione spray

  1. Shake the bottle well.
  2. Spray 1 to 2 times into your mouth per use.
  3. Hold it in your mouth for a few seconds before swallowing.
  4. Store with the cap on, away from heat and direct sunlight.

Bulk Essentials Glutathione Spray comes in 200mg and 500mg bottles and has just three ingredients: glutathione, purified water and sodium citrate. No sugars, flavors or fillers, and no pills to swallow.

Support your body's own production

  • Protein: eggs, poultry, fish and legumes supply the amino acid building blocks. Our Glycine Powder and L-Glutamine Powder are easy ways to add two of them.
  • Sulfur-rich vegetables: broccoli, cabbage, garlic and onions.
  • Vitamin C: helps keep glutathione in its active form. Try our Pure Vitamin C Powder.
  • Sleep and movement: regular exercise and good sleep support healthy antioxidant defenses.

Glutathione and NAD+

Glutathione and NAD+ work on different sides of cellular health: NAD+ fuels energy production and repair, while glutathione supports antioxidant protection. That's why many customers take Glutathione Spray together with NAD+ Spray each morning. Learn more in What is NAD+?

Safety

Glutathione is generally well tolerated. Talk to your doctor before use if you're pregnant, nursing, taking medication or have a medical condition.
