Vitamins A and D together, effectively

Vitaking Vitamins A and D contains 10000 IU of Vitamin A and 1000 IU of Vitamin D per capsule.

Vitamin A is also referred to as retinol, retinol equivalent, or retinal, but is also often heard as an epithelial vitamin. It can also be formed in the body from its precursors, called provitamins. The most common precursors are various carotenoid compounds, the most active of which is ß-carotene, which is found in carrots and apricots. These compounds are able to be converted to vitamin A in the intestinal tract when needed, albeit with varying degrees of efficacy.

Vitamin A:

• Participates in proper iron metabolism.
• It helps maintain the normal condition of the skin.
• It helps maintain normal vision.
• It helps maintain the normal condition of the mucous membranes.
• It contributes to the normal functioning of the immune system.
• Vitamin A plays a role in cell differentiation.

Vitamin A requirements are measured in micrograms (ug). Other designations are used, NE (International Unit) or IU (International Unit). 1 IU of vitamin A is equivalent to 1 ug of retinol, 6 ug of ß-carotene, or 12 ug of other carotene.
70-90% of the vitamin A and 20-50% of the carotenes ingested with food are utilized. The presence of fat is, of course, necessary for healthy absorption, and research has shown that vitamin E also has a beneficial effect on the utilization of dietary vitamin A.

Vitamin D:

• It contributes to the normal absorption / utilization of calcium and phosphorus.
• It helps maintain normal blood calcium levels.
• It helps maintain healthy bones.
• It helps maintain healthy muscle function.
• Contributes to the maintenance of normal teeth.
• It contributes to the normal functioning of the immune system.
• It plays a role in cell division.

As a result of ultra-viola (UV-B) radiation reaching our skin, our body is able to produce vitamin D mainly from cholesterol in a complex, multi-step process. With this, we get a little out of the wildlife, as furry-feathered individuals are apparently only able to get vitamin D from a dietary source, being never exposed to light on their skin.

But most people spend one or two weeks a day a year, the rest of their time in offices, houses, cars, or other enclosed spaces, typically dressed and barely exposed to sunlight. If you also get little sunlight, it is advisable to supplement with vitamin D.
