Premier Research Labs D3 Serum

The most natural way to get vitamin D is by exposing your bare skin (no sunblock) to sunlight for 20 minutes daily. Still, 80% of the lab tests we ran in our practice came back deficient in Vitamin D. It is very important to test and to also make sure you have enough vitamin K2 in your diet for Vitamin D absorption. Vitamin D is essential for healthy calcium metabolism, as it promotes intestinal calcium and phosphorus uptake and can also reduce urinary calcium excretion. It supports the bones, nerves, heart, brain, lungs, esophagus, breasts, colon, stomach, pancreas, prostate, uterus, ovaries and the kidneys. PRL's high-quality, live-source vitamin D3 liquid provides targeted immune and cardiovascular support with no toxic tagalongs, plus it's in olive oil which further improves absorption. Studies propose ideal vitamin D3 intake should be 2000 IU or more daily, but it really depends on your personal test results. The Vitamin D Council suggests that a level of 50 ng/ml is the optimal level to aim for.
