Most participants had minimal or mild depression, had a low mean baseline 25(OH) level of 33.8 nmol/L (13.5 ng/mL), and were not taking antidepressants. Participants were randomized to take either 30 mcg (1,200 IU)/day vitamin D3 or a placebo for 1 year. The groups showed no significant differences in the incidence and recurrent rates of depression, clinically relevant depressive symptoms, or changes in mood scores. In contrast to the observational studies, clinical trials have provided little support for the hypothesis that supplemental vitamin D reduces the risk of CVD or CVD mortality.
Federal agencies and national organizations advise taking photoprotective measures to reduce the risk of skin cancer, including using sunscreen with a sun protection factor (SPF) of 15 or higher, whenever people are exposed to the sun [28,30]. Sunscreens with an SPF of 8 or more appear to block vitamin D-producing UV rays.

A deficiency in this nutrient leads to increased levels of pro-inflammatory molecules that diminish immune system response and function (18). Studies show that higher blood levels of beta carotene, alpha carotene, and beta cryptoxanthin may reduce your risk of AMD by up to 25% (15). It supports immune function by supporting the growth and distribution of T cells, a type of white blood cells that protect your body from infection (8).

The following table lists chemicals that had previously been classified as vitamins, as well as the earlier names of vitamins that later became part of the B-complex.

Bone health also depends on support from the surrounding muscles to assist with balance and postural sway and thereby reduce the risk of falling. Vitamin D is also needed for the normal development and growth of muscle fibers. In addition, inadequate vitamin D levels can adversely affect muscle strength and https://vitamister.ch + online pharmacy lead to muscle weakness and pain (myopathy) [1].
However, a post hoc analysis showed a 62% lower incidence of diabetes among participants with low baseline serum 25(OH)D levels (less than 30 nmol/L [12 ng/mL]) who took the vitamin D supplement than among those who took the placebo [145,150]. High serum cholesterol levels and hypertension are two of the main risk factors for CVD. The data on supplemental vitamin D and cholesterol levels are mixed, as shown in one meta-analysis of 41 clinical trials in a total of 3,434 participants (mean age 55 years). Obtaining sufficient vitamin D from natural (nonfortified) food sources alone is difficult.
Vitamin A is an important fat-soluble vitamin that supports your immune system, vision, reproductive health, and fetal growth. Even though it’s essential to get enough, taking too much can be harmful. Because endogenous vitamin D is derived from cholesterol, statins may also reduce vitamin D synthesis [167]. Overall, the available research suggests that consuming higher amounts of vitamin D or taking vitamin D supplements does not promote weight loss.
