Evidence profile
Glutathione (1500 mg Vial)
Glutathione participates in antioxidant biology. A biological role does not by itself establish benefit from a particular supplement or injectable product.
01
Product identity
Chemical form and administration route are part of the evidence, not interchangeable details.
02
What has been studied
Primary human study
An oral skin study
- Population or model
- Healthy women
- Study route or material
- Oral supplementation
A randomized 12-week study in healthy women evaluated oral reduced and oxidized glutathione and reported changes in selected skin measures. It does not test the supplier-listed vial or its proposed subcutaneous use.[1]
03
Evidence limits
Subcutaneous efficacy, a compatible diluent and product-specific stability have not been established by the reviewed source.
The reviewed sources do not establish patient instructions for this product. No dose, cycle, preparation method or administration schedule is provided here.
04
Formulation and handling evidence
Reduced versus oxidized form, actual strength, excipients and container capacity.
Product-specific compatibility and stability data; do not infer these from an oral study.
A compatible diluent, prepared-solution stability and container/device compatibility must be supported for the exact formulation. The diluent manufacturer’s instructions do not supply a universal storage period for every dissolved substance.[3]
05
Approval context
This profile has not established Canadian authorization of the linked research product.[2]
