Two phrases sit near each other: not a testosterone booster, and zinc's role in normal testosterone maintenance.
Maintenance means helping to keep a level in its normal range, which is a more modest claim than raising it. The statement is about zinc as a nutrient: the body needs it for normal function, and being short of it can matter for hormone levels.
It does not say a gummy will raise your testosterone, and the page says it does not claim that.
The topic is central to why people search for the product, so the wording feels closer to a promise than it is. Zinc status matters mostly if you are low in it, and the per-gummy amount here is not published. Only a blood test can tell you anything about your own levels. Our zinc guide has more.
