The Claim
In physically active seniors aged 57–72, daily supplementation with 400 mg of Tongkat Ali for five weeks is associated with a significant decline in sex hormone-binding globulin concentrations in women and a concurrent rise in free testosterone.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In physically active men and women aged 57–72, taking 400 mg of Tongkat Ali daily for five weeks is linked to lower levels of sex hormone-binding globulin and higher levels of free testosterone in women.
See the scientific wording
In physically active seniors aged 57–72, daily supplementation with 400 mg of Tongkat Ali for five weeks is associated with a significant decline in sex hormone-binding globulin concentrations in women, which may explain the concurrent rise in free testosterone.
Tongkat Ali causes the liver to produce less of a protein that binds testosterone, so more testosterone circulates freely in the blood and can activate muscle cells.
What the research says
1 studyIn older women who took Tongkat Ali daily for five weeks, a protein that traps testosterone dropped, which likely let more testosterone become active in their bodies. This matches what the claim says.
