It has been estimated that the average human brain contains about 100 billion neurons and, on average, each neuron is connected to 1000 other neurons. This results in the generation of vast and complex neural networks that are the mainstay of the brain's processing capabilities. Neurons are the basic data processing units, the 'chips', of the brain. Each neuron receives electrical inputs from about 1000 other neurons.
New research from Italy suggests that low levels of vitamin D may increase your risk of erectile dysfunction. When researchers tested 143 men with varying degrees of erectile dysfunction, they found that nearly half of them were coming up deficient in D, and only one in five had optimal levels of the nutrient.
Men with low vitamin D levels are much more likely to have low testosterone levels when compared to men with adequate amounts of the vitamin. 2. Healthy men who decide to supplement with low dose vitamin D, can expect to have around 25% more testosterone in their bloodstream after a year of supplementation. 3. If your serum vitamin D levels are already in the optimal range, you might not get a testosterone boosting benefit from extra supplementation.
