There are several factors to consider when choosing the best glutathione with vitamin C supplement, including choosing a dose that is considered safe and a form of drug delivery that offers good absorption. Both compounds are powerful antioxidants that may support immune system function. Glutathione is not easily absorbable through the gastrointestinal tract, however, so injections of glutathione and vitamin C offer the best absorption for both substances.
A number of chemical reactions take place in the human body every day and a natural by-product of these reactions are cells known as free radicals. These are reactive and can cause oxidative damage to healthy cells. This type of cellular damage may be worsened by high levels of environmental pollutants and may be linked to a number of disease processes, such as Alzheimer’s and cancer. Antioxidants like glutathione with vitamin C are molecules that protect cells against oxidative damage by inhibiting the action of free radicals. Some experts believe that supplemental antioxidants may help to neutralize free radicals, especially during periods of increased physical or psychological stress.
A peptide synthesized in the body, glutathione is important for proper immune system function and can help combat oxidative damage. Scientific studies indicate the compound cannot be sufficiently absorbed through the gastrointestinal tract. Additionally, oral supplements are largely ineffective at boosting glutathione levels and having an antioxidant effect. Inhalable or injectable compounds appear to have better absorption.
Vitamin C is a water-soluble compound, so it is excreted when intake surpasses the body’s needs for the nutrient. It is commonly found in fruits and vegetables and is highly absorbable in capsule or pill form. The recommended dose of glutathione supplements is 600 mg a day, while typical doses for vitamin C range from 1000-2000 mg a day. In addition to supplementation of these substances for other medical conditions, physicians sometimes use injectable glutathione as part of a treatment regimen for Parkinson’s disease. Medical studies show people with Parkinson’s tend to have low levels of the peptide and boosting levels through supplementation may slow down progression of the disease.
In high doses, glutathione may lead to skin lightening and dermatologists may use it for this purpose. To ensure maximum bioavailability and absorption of both compounds, glutathione with vitamin C may be given in an injectable form by a qualified medical professional. Supplementation can have side effects like nausea, indigestion, and diarrhea. Injectable glutathione with vitamin C compounds are usually given through an intramuscular injection or an intravenous infusion, and, like with all injections, there is a very small risk of infection at the injection site.
