L-Glutathione Nasal Sprayfor Cellular Defense.

Ideal for adults looking to support antioxidant defenses, detoxification, immune health, healthy aging, skin radiance, and cellular energy - especially those whose natural glutathione may be lower due to age, stress, or environmental exposure. Not for pregnant or nursing women, or children, unless directed by a physician. Avoid if you have asthma or a sulfur allergy.

Oral glutathione is largely broken down in the digestive tract, so the amount that reaches your system varies. The nasal spray bypasses digestion, absorbing through the nasal lining for more direct delivery - including a more direct route toward brain tissue, which oral forms struggle to reach.
