What is Glutathione?
Glutathione is a combination of three amino acids —
- Glycine
- Cysteine
- Glutamic Acid
Known as GHS, glutathione is naturally produced in the liver and the nerve cells of the central nervous system. It is an antioxidant that helps to fight free radical damage to the body’s cells. An excess of free radicals over antioxidants will result in inflammation and several health problems, including Alzheimer’s disease, high blood pressure, and diabetes.
Glutathione has also been shown to play a role in DNA creation and repair, protein production, and the activation of enzymes. It is also involved in the breakdown of nutrients for absorption and digestion.
Research into potential side effects of glutathione is incomplete. There is evidence that supplementing with glutathione may cause bloating and cramping in some people. Some people have also experienced allergic reactions to the supplement, like a body rash.
Researchers believe that the key active ingredient in glutathione is cysteine. Furthermore, glutathione is abundant in many fruits and vegetables and freshly prepared meats.
What to Look For in a Glutathione Supplement
Even though they may look alike, not all glutathione supplements are equal. Here are three key things to look out for to make sure that you are getting a high-quality supplement —
Absorbency
If your body is unable to absorb the supplement, it doesn’t matter how good the ingredients in a supplement are. When it comes to the bioavailability or absorbency of glutathione, you should go with liposomal glutathione.
So what is liposomal glutathione? It is glutathione that has been encapsulated using liposomal technology in minute fat bubbles to protect the three amino acids that make up the compound (cysteine, glutamine, and glycerine). It allows them to pass directly through the intestine and into the bloodstream, improving the bioavailability of the compound.
You should also make sure that your glutathione supplement is reduced. It is a process by which the oxygen is reduced, and hydrogen and electrons are increased. The process makes the supplement more effective in its ability to fight free radical damage.
Ingredient Quality
Check the label to ensure the glutathione in the product comes from a non-GMO source. That means it should not be made from soy lecithin, which contains GMOs. A much better option is non-GMO sunflower lecithin.
Glutathione contains a high concentration of sulfur, which gives it a sulfuric taste and smell. To mask this, many manufacturers add sugar and other sweeteners to the product. You should check that the product does not contain artificial sweeteners such as aspartame or sucralose. Instead, look for a supplement that uses natural flavors and stevia.
Manufacture
Look for a manufacturer that provides complete transparency about their product. It should tell you where the product is manufactured and what the ingredients and dosages are (no proprietary blends). The manufacturer should also have verified user reviews on their website. Furthermore, companies that use third-party testing should be preferred.
How We Decided Our Picks
In narrowing it down to our top 10 glutathione supplements, we considered a large number of products. In making our selections, we took the following factors into account —
Label
We carefully checked the label on all of the glutathione supplements we reviewed to ensure they provided a large enough dose of the active ingredient to do what it promises.
However, that doesn’t mean that we only included higher-dose supplements because there are no research guidelines regarding glutathione dosage. Hence, we included higher and milder doses to suit all needs.
Purity
When you buy a glutathione supplement, you deserve to get a pure product. We carefully checked out short-listed products to ensure they were free from fillers, preservatives, and flavorings.
Third-Party Testing
Companies that use third-party testing to verify the potency and purity of the supplements provide you with a high level of consumer confidence. That’s why we favored manufacturers who employed third-party testing on their glutathione supplements.
Glutathione Supplement Dosage
There are currently no direct research-based recommendations regarding glutathione supplementation dosage. Studies have generally been specific to the treatment of particular conditions and have used widely disparate dosages.
In the absence of a definitive clinical recommendation, we recommend that you follow the manufacturer’s guidelines as far as dosage goes.
What are the Benefits of a Glutathione Supplement?
Glutathione is one of the most powerful antioxidants on the market. It can negate the destructive activity of free radical molecules that cause damage to the cells of the body. The stress caused by intense exercise is believed to increase free radical activity, making it especially beneficial for people who regularly engage in intense exercise.
Here are six other benefits of taking a glutathione supplement —
- Helps with psoriasis.
- Reduces cell damage caused by fatty liver disease.
- Improves insulin resistance.
- Increased mobility for those with peripheral artery disease.
- Reduces symptoms of Parkinson’s disease.
- Helps offset the biomarkers of aging.
Many people also claim that glutathione can lighten a person’s skin. There are many glutathione-based skin whitening products on the market. However, there is very little research to support the idea.
FAQs
Who Should Take a Glutathione Supplement?
Glutathione is a general health and well-being supplement that can benefit everybody. As a powerful antioxidant, it could improve the overall health of whoever takes it.
What does glutathione do for the body?
Glutathione acts as an antioxidant to fight against the destructive activity of free radical molecules that damage the body’s cells. It also helps with food absorption, protein production, enzyme activation, and energy production.
Does glutathione lighten the skin?
There is some evidence that glutathione may cause skin lightening. In some countries, it is marketed as a skin-lightening product. However, the skin brightening effect of glutathione appears to only work when you apply it topically before exercise.
