Glutathione, or GSH, in itself, is an entirely risk free nutrient. Your body already makes glutathione naturally within its cells, and it is necessary for their survival. In addition, it is impossible to overdose on glutathione because an enzyme involved with the synthesis of glutathione halts its production before toxic levels are reached.
Allergies to Glutathione Precursors
With that said, there are several supplements that provide the body with the precursors of glutathione, leaving its actual production to your body’s natural processes, that may pose a slight risk to select consumers. For example, undenatured whey protein is one supplement used to increase glutathione levels in the body. Undenatured whey protein promotes increased glutathione levels by providing the body with cysteine, the only amino acid needed for the production of glutathione that the body can run short on. The risk posed by this supplement is for those who are hypersensitive or allergic to specific milk proteins. Because the users of undenatured whey protein are consuming large quantities of the supplement, they will experience an unpleasant gastrointestinal reaction to the milk proteins contained in the powder. However, non-allergic users will not experience any negative side effects.
Allergic Reactions to the Glutathione Precursor NAC
Only supplements that are precursors, or building blocks, for glutathione are the only supplements that present any type of risk to the user. The glutathione precursor N-Acetylcysteine, or NAC is a glutathione precursor that is generally safe to consume. However, unlike glutathione, it is entirely possible to overdose on NAC. Symptoms of NAC overdose include nausea and vomiting, as well as possible anaphylaxis, which is the same type of allergic reaction that individuals with bee sting allergies present when stung. Therefore, it is of the utmost importance to follow the indications listed on the supplement’s packaging. In addition, NAC should not be administered to infants or children. When used properly, N-Acetylcysteine poses a minimal risk to the competent adult user.
Glutathione is Not Dangerous
It is important that glutathione enthusiasts realize that glutathione in itself is not dangerous in any way, shape, or form. In fact, glutathione is an essential antioxidant, immunity booster, and natural detoxifier in the human body. It is only when individuals misuse supplements that are the building blocks for glutathione that any risk can arise. Even then, these risks can be entirely avoided if the consumer reads the allergy information and identifies the correct dosage for his or her personal needs. Striving to increase one’s glutathione levels is an entirely commendable goal. However, you need to realize that while glutathione itself cannot harm you, the building blocks of glutathione included in some supplements can be harmful when improperly used.
