The human body is an incredibly complex machine and science is still far from uncovering the secret of how it all works yet. What is sure however is that such a complex system of processes requires quality fuel, and that comes in the form of energy (calories) as well as all the essential vitamins and minerals to support its tasks.
Examples of processes that requires adequate micronutrients are things such as sperm production, hair growth, deep sleep, thyroid energy production and of course testosterone synthesis. If you’re lacking in some micronutrients then you run the risk of impairing some of these processes.
