Zinc is quite possibly the most underrated semen-volumizing mineral in the world. That’s because your semen actually contains zinc! That’s right, your semen is made with a “cocktail” of nutrients and one of them happens to be zinc. So, making sure you have plenty of zinc is crucial for more volume. In fact, several studies show zinc has a testosterone-boosting effect. And testosterone is also crucial for releasing large amounts of semen. That’s why each dose of Max Volume contains this essential semen-volumizing nutrient. A clinical study found that zinc can elevate semen volume by up to 26%.
