Did you know that zinc deficiency is one of the leading causes of low testosterone? Zinc is a mineral essential to our body that plays a pivotal role in bodily functions such as healing wounds and immune function. A person’s body does not store zinc, so you must be ingesting adequate amounts of zinc daily. Sometimes it can be hard to get enough zinc through food alone, so Dr. Huberman supplements it daily to ensure he is not jeopardizing his testosterone with a lack of zinc intake. Huberman uses Momentous Zinc Picolinate, a much more bioavailable form of zinc than others on the market.
