There are huge numbers of testosterone creams, pills, and injections as well as ads convincing men they are in need of these products. There are also thousands of lawsuits filed against the manufacturers of the various testosterone therapies claiming the drugs caused several severe cardiovascular side effects including heart attack and stroke. With this knowledge, Men’s Journal published an article describing natural ways men can boost their testosterone through diet so as not to take on unnecessary risks. One suggestion made was to increase vitamin D intake which could increase testosterone level. Men should always use caution and discuss diet changes with their doctor.
