Awesome supplement
Vitamin D continues to  prove that it’s one of the most important vitamins you can take. Calcium plus Vitamin D may cut body fat.
Shows anti-diabetic activity. Helps protect blood vessel health. Helps control blood sugar.  Cuts fat mass.
May reduce depression. Lots of healthy benefits, but Vitamin D does more than just improve your overall health profile. Scientists have learned that it can create a tremendous boost to athletes including the benefit of building muscle. Vitamin D is helpful in promoting muscle growth because your muscle fibers have Vitamin D receptors and, when adequate Vitamin D is provided, studies have shown that these receptors encourage greater leg and grip strength. When Vitamin D is plentiful, it interacts with receptors, signaling genes to increase muscle strength and mass. Basically, Vitamin D gets converted in your body into a steroid hormone (1,25- dihydroxy Vitamin D); so, it’s logical to conclude that Vitamin D has a musclebuilding effect. Excess Vitamin D is then stored in fat tissue so that it will be available for future use. While your body can’t increase its receptors, getting in an adequate amount of Vitamin D will help make sure that your body is able to maximize strength and muscle mass by saturating the receptors that you have. Why athletes need Vitamin D It’s important for active people, especially athletes and those who train intensely in the gym, to get enough Vitamin D. Sports Medicine Researchers recently did a study that found that athlete who had low Vitamin D levels suffered more muscle injuries than those who had higher labels.

How much Vitamin D3 should you take? Supplementing with Vitamin D3 is a must, even in summer. Vitamin D3 is usually sold in soft gels. For best results, supplement 1,000 IU of Vitamin D3 once or twice a day with food. In general, take 2,000-5,000 IU of Vitamin D3 every day to make sure you’re getting enough of this extremely important nutrient. Outdoor workouts are a key benefit in summer, but don’t forget to protect your skin. Careful of the sun
Beeing in the sun is not a
risk-free activity, not just because of painful sunburn but the possibility of developing the worst, Melanoma (skin cancer). While you need the enriching nutrients of sunlight, you need to protect yourself from overexposure to UV rays. Using sun block is essential if you plan to be outside for long stretches of time. Pick a quality brand with a minimum of 15 SPF, and use 30 SPF if you have sensitive skin. While sun block helps you bronze safely by blocking
some of the most harmful UV molecules, it also limits the amount of Vitamin D you absorb. Therefore, supplementing with Vitamin D is crucial no matter your racial background or age.
