Now Foods Vitamin D-3 is a dietary supplement containing 5000IU of cholecalciferol per capsule.
Cholecalciferol - is an organic chemical compound from the group of vitamin D. It is fat-soluble and has the ability to be stored in the body. It is best known for its effects on calcium metabolism and positive effects on bones, but in recent years many more health properties of vitamin D have been discovered, on virtually every system in our body. It is synthesized on the skin under the influence of UV-B rays on 7-dehydrocholesterol.
Benefits of taking Now Foods Vitamin D-3 supplement:
The prevalence of deficiency in the population
It is estimated that up to 90% of the population may have insufficient levels of vitamin D in their blood. This makes the vitamin infamous as the most deficient nutrient. The reason for this may be low exposure to sunlight during the hours of 11 am to 2 pm, which have the highest UV-B emissions. Unfortunately, these hours coincide with the working hours of most of the population, making it impossible to benefit from the sun's health-promoting properties.
Calcium and phosphorus management
Vitamin D effectively promotes the absorption of these minerals in the intestines, and subsequently benefits their utilization. It also contributes to the regulation of calcium concentration in the blood. The lowering of parathormone levels by vitamin D may contribute to reducing the release of calcium from stores in the bones, allowing the body to maintain a higher mineral density.
Self-esteem and mental health
Cholecalciferol is characterized by strong effects on mood regulation. Low levels of this vitamin in the blood have been found to be associated with an increased risk of depression and mood-related disorders. Vitamin D deficiencies have also been linked to impaired sleep quality, which can be corrected once deficiencies are regulated. Better sleep, on the other hand, means more energy throughout the day and more efficient functioning of the entire body. Vitamin D has shown the ability to modulate calcium channels in neurons. It can also control cell death by excitotoxicity. One may be tempted to conclude that this vitamin protects the nervous system and may contribute to maintaining mental performance for a longer period of time.
Hormonal activity of vitamin D
The view of this vitamin changed dramatically when vitamin D receptors (VDRs) specific to it were discovered in most cells of the human body. This has shed new light on its functionality, as it indicates a hormonal effect.
Effects on testosterone
Supplementation with cholecalciferol contributes to an increase in testosterone levels in men who previously complained of low levels. It can also result in a decrease in SHBG, or sex hormone-binding globulin, thus increasing the concentration of biologically active free testosterone. What's more, vitamin D supplementation has been observed to slow the decline in androgens resulting from aging, allowing the body to enjoy vitality for a longer period of time.
Benefits for athletes
The effect on muscle function translates into better body control and stronger activation of muscle fibers for work. Regulation of androgen levels and tissue sensitivity to insulin allows maximization of anabolic processes and optimal utilization of nutrients. Beneficial effects on fat reduction support are also noted, thanks in part to elevated adiponectin. Research confirms a subtle effect on increasing the burning of spare body fat in people who previously suffered from vitamin D deficiency.
Now Foods Vitamin D-3 is recommended in cases of established vitamin D deficiency in the blood.
It can also be used to improve general health and as a support for people who train intensively.
