QUESTION: What's been shown to boot testosterone levels?
ANSWER: Calcium. Yes, this mineral is best known for its bone-boosting benefits, as well as its ability to aid fat loss, but calcium also has a lesser known benefit—testosterone boosting.
Researchers from Selcuk University (Turkey) reported that athletes taking about 16 milligrams of calcium per pound of bodyweight (that’s about 3,000 mg for a 200-pound guy) had higher testosterone levels during workouts than subjects not taking supplemental calcium.
To boost your testosterone, take 500–600 mg of calcium two to five times a day.
