Analysis

Source Naturals Reduced Glutathione 250 mg is a focused supplement designed to provide a direct dose of L-Glutathione, the body's master antioxidant. At 250mg per serving, it offers a much more meaningful quantity than the nominal amounts present in multi-ingredient formulas, making it more relevant for individuals specifically targeting detoxification, anti-aging, or immune support through glutathione pathways. While 'reduced' indicates the active form, a widely acknowledged challenge with standard oral L-Glutathione is its relatively poor bioavailability, as it can be broken down in the digestive tract. This product is a cost-effective option for those who prefer a single-ingredient approach, but consumers seeking maximal absorption might consider more advanced forms like liposomal or S-acetyl glutathione.

Pros
  • Provides a dedicated and more substantial dose of L-Glutathione (250mg) compared to multi-ingredient formulations.
  • Relatively inexpensive per serving, making it an accessible option for regular glutathione supplementation.
  • Contains 'reduced' glutathione, which is the active and bioavailable form within the body, if absorbed.
Cons
  • Standard oral L-Glutathione has documented issues with bioavailability due to degradation in the digestive system, meaning a significant portion may not reach systemic circulation.
  • Some individuals might require higher dosages (e.g., 500mg or more) for therapeutic effects, depending on their health goals.
  • The inclusion of Calcium as dibasic calcium phosphate is an inactive ingredient, though generally benign.
Warnings
  • Individuals taking medications, especially chemotherapy, should consult a healthcare professional before supplementing with glutathione, as it might interact with certain treatments.
  • While generally safe, some people may experience mild digestive upset.

Report overview

Categories

This product directly provides a substantial dose of reduced L-Glutathione, making it a dedicated source for those seeking to specifically supplement this compound. The score reflects its direct provision of glutathione but acknowledges the general bioavailability challenge of this form.

Goals

Glutathione is a potent antioxidant and critical for immune cell function, directly supporting the body's defense mechanisms. The 250mg dose provides a good foundation, though bioavailability can limit its ultimate impact.
As the body's master antioxidant, glutathione plays a crucial role in combating oxidative stress and cellular damage, key factors in the aging process. Regular supplementation can support cellular longevity, assuming adequate absorption.
Glutathione is central to the body's detoxification pathways, particularly in the liver, by neutralizing toxins and supporting their elimination. A 250mg dose contributes to this process, though for intensive detoxification, higher doses or more bioavailable forms might be preferred.
