Small studies have shown inconsistent results, and theres no strong evidence that it meaningfully improves menopause or PMS symptoms.38 Taken together, these ingredients provide overlapping support for both menopause-related symptoms and PMS, which helps explain why this formula performs well across both categories even if not every component is equally well supported by research

Maintaining optimal levels of glutathione appears to be important for supporting cognitive function, especially as we age.* The normal process of aging is associated with a decrease in glutathione regulation, which can result in increased oxidative activity.* Less than optimum levels of glutathione are observed in individuals experiencing a decline in cognitive function.* Conversely, individuals living over 100 years tend to have higher glutathione reductase activity.* A common mistaken belief is that glutathione is not well absorbed when its taken orally, but significant data confirms it is efficiently absorbed across the intestinal epithelium by a specific uptake system.* Glutathione-SR from Thorne Research represents an important breakthrough in glutathione supplementation
