1 Essential Vitamin Missing from Your Diet

Why Vitamin D Is Necessary for Testosterone

Do you get enough Vitamin D? The “sunshine vitamin” is essential for testosterone production and your health. However, an estimated 1 billion people have inadequate levels of vitamin D because they do not spend enough time in the sun. (1, 2)

If you are over the age of 50, overweight, or don’t get at least 15 minutes of direct sun exposure per day, you are at high risk of Vitamin D deficiency. (2)

Vitamin D deficiency leads to low testosterone and can increase the risk of chronic diseases such as osteoporosis, heart disease, some cancers, obesity, diabetes, multiple sclerosis, as well as infectious diseases, such as tuberculosis and the seasonal flu. Doctors are even seeing the resurgence of rickets, a bone-weakening disease, due to lack of Vitamin D. (1, 3)

Sun exposure is the best way to get your vitamin D levels into the healthy range. A daily 15-minute walk in the sun is a proven and effective method. If you wear sunscreen, know that correctly applied sunscreen reduces your ability to absorb vitamin D by more than 90 percent. (2)

Few foods are naturally rich in vitamin D, but good food sources of vitamin D include eggs, mushrooms, and fatty fish such as salmon, tuna, and cod liver oil. (3)

Boosting your vitamin D will help Andro400 work more efficiently to restore testosterone to healthy levels, which will promote muscle, bone, and heart health as well as improve mood, libido, energy, stamina, and your immune system. (4)
