Nutri-West Complete Hi D-3 is a vitamin D3 5000 IU supplement derived from the liver oil of the cod fish. Vitamin D is an essential vitamin‚ meaning that our bodies can't synthesize or produce it‚ but it is still absolutely crucial for maintaining health. Now‚ it's possible to get vitamin D through your diet‚ but is only found in small amounts in certain fatty fish. That's why a dietary supplement like Nutri West's complete Hi D-3 with Vitamin D3 5000 IU is a great resource for maintaining your health. It must also be made clear that our main source of vitamin D is sunlight. By just spending a few minutes everyday in the sun‚ our bodies can absorb and store all the vitamin D we would need for quite some time. However‚ not everyone has the opportunity to expose their skin to sunlight. Living in a region with very little sunlight‚ or having darker skin can inhibit one's vitamin D levels. This is another reason why this vitamin D3 5000 IU supplement is a great choice for those not getting the adequate amount of vitamin D. In terms of health benefits‚ vitamin D has been gaining a lot of attention recently. One of the most well known potential health benefits of vitamin D3 5000 IU is it's regulation of calcium and phosphorus in the body. This means that if an individual has low levels of phosphorus or calcium in the blood‚ Complete Hi D-3's vitamin D3 5000 IU may help even out that balance. Vitamin D supplements and calcium supplements are often formulated together since vitamin D is traditionally viewed as essential for bone health‚ just like calcium.
