Eggs are one of the few natural suppliers of vitamin D, which is essential for testosterone production.
A study published in Hormone and Metabolic Research shows supplementing with vitamin D can increase testosterone levels. A significant increase in total testosterone, bioactive testosterone, and free testosterone levels was observed in a vitamin D supplemented group.
Eggs are also considered to be the most inexpensive high-quality protein money can buy. The yolk supplies a wholesome dose of healthy fat, too.
Specifically, when fortified, milk is a rich supplier of vitamin D.
Milk is also a significant source of protein and calcium, which are essential nutrients for supporting muscle mass and bone health.
Opting for lower fat milk reduces overall fat and calorie content while still preserving protein, calcium, vitamin D, and other nutrients.
