In context
Glutathione is an endogenous antioxidant. A six-month placebo-controlled trial in 54 adults examined whether oral supplementation changed glutathione concentrations in several tissues. [1]
At a glance
- Type
- Peptide / related clinical research
- Regulatory context
- The cited source describes research, not a determination of present marketing authorisation. Country, formulation and indication must be checked separately.
- Evidence
- Changes in tissue concentrations are not proof of disease prevention, skin lightening or benefit from intravenous use. Route and formulation matter.
How to interpret this evidence
Changes in tissue concentrations are not proof of disease prevention, skin lightening or benefit from intravenous use. Route and formulation matter. [1]
Safety and clinical context
The evidence described here does not establish safety for unsupervised use. Product identity, route, formulation, interactions and long-term effects cannot be inferred from a study category.
Evidence and authorisation depend on the product, formulation, indication and country. US labelling does not establish Thai authorisation. This guide is educational and is not a dosing or self-treatment protocol.
