To find out if you have low vitamin D levels, your doctor will give you a blood test. If your levels are severely low, they may prescribe a loading dose course of vitamin D. This is a high strength dose that is only available on prescription.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

The Journal of Clinical Endocrinology and Metabolism. 104 (8): 3148–3156. doi: 10.1210/jc.2018-01874. PMID 30896763. S2CID 84841517. Supplements and Herbs that claim to have Weight Loss benefits are often suspect and end up being parts of fad diets that do not work. There are some studies suggesting that Vitamin D can help with weight loss. Vitamin D supplementation is not associated with a reduced risk of stroke, cerebrovascular disease, myocardial infarction, or ischemic heart disease. [13] [77] [78] Supplementation does not lower blood pressure in the general population. [79] [80] [81] Immune system [ edit ] Infectious diseases [ edit ]Vitamin D is essential for immune health and disease prevention. In fact, some research suggests vitamin D deficiency could worsen or increase the incidence of certain autoimmune conditions, such as rheumatoid arthritis [3] Ao T, et al. The Effects of Vitamin D on Immune System and Inflammatory Diseases. Biomolecules. 2021;11(11):1624. . “There is also evidence that maintaining vitamin D sufficiency reduces the long-term risk of developing certain types of cancer,” adds Dr. White. Hydroxylation in the kidneys of calcifediol to calcitriol by 1-alpha-hydroxylase is tightly regulated: it is stimulated by parathyroid hormone and serves as the major control point in the production of the active circulating hormone calcitriol (1,25-dihydroxyvitamin D 3). [2] Just 3 ounces of rainbow trout provides 645 IU for 81% of the DV. It is also rich in heart-healthy omega-3 fatty acids. Potential associations have been found between low vitamin D levels and the risk of developing several types of cancer. [73] [74] Meta-analyses of observational studies have found reduced risk of cancer incidence related to vitamin D intake and 25(OH)D levels, particularly for colorectal cancer, although the strength of the associations was classified as weak. [74] [75] While randomized controlled trials have not confirmed that vitamin D supplements reduce the risk of cancer incidence, the relative risk of cancer deaths was lower by up to 16% in several meta-analyses. [76] [75] Cardiovascular disease [ edit ] Australia and New Zealand published nutrient reference values including guidelines for dietary vitamin D intake in 2006. [114] About a third of Australians have vitamin D deficiency. [125] [126] European Union [ edit ]

Your bones need calcium to maintain the health and mineral density of your precious skeleton, but as it turns out, getting enough vitamin D is essential to calcium absorption in your bones and body. Low levels of Vitamin D3 are associated with elevated levels of Cholesterol (about 129% higher). Specifically, people with Low Vitamin D levels had higher LDL Cholesterol ( “Bad” Cholesterol) levels.
In 2016 in the United States, the Food and Drug Administration (FDA) amended food additive regulations for milk fortification, [138] stating that vitamin D 3 levels not exceed 42 IU vitamin D per 100 g (400 IU per US quart) of dairy milk, 84 IU of vitamin D 2 per 100 g (800 IU per quart) of plant milks, and 89 IU per 100 g (800 IU per quart) in plant-based yogurts or in soy beverage products. [139] [140] [141] Plant milks are defined as beverages made from soy, almond, rice, among other plant sources intended as alternatives to dairy milk. [142] Many people are Vitamin D deficient—especially in the winter so moderate supplementation is probably a good idea. Before diving into the world of mega-dosing D3, be sure to speak with your physician first. Overdosing on a vitamin D supplement can be toxic and therefore detrimental to your health. Tripkovic L, Lambert H, Hart K, Smith CP, Bucca G, Penson S, etal. (June 2012). "Comparison of vitamin D2 and vitamin D3 supplementation in raising serum 25-hydroxyvitamin D status: a systematic review and meta-analysis". The American Journal of Clinical Nutrition. 95 (6): 1357–64. doi: 10.3945/ajcn.111.031070. PMC 3349454. PMID 22552031. Because Vitamin D and calcium are related too much Vitamin D can lead to Calcium issues. These issues include, Hypercalcemia, Kidney Stones and Kidney damage.
Key facts
In general, vitamin D 3 is found in animal source foods, particularly fish, meat, offal, egg and dairy. [133] Karampela I, et al. Vitamin D and Obesity: Current Evidence and Controversies. Curr Obes Rep. 2021;10(2):162-180. Maintaining adequate levels of vitamin D may offer several potential benefits: Enhances Bone Health Over 18% of the population exceeds the NIH daily recommended allowance ( RDA) of 600–800 IU, [2] by taking over 1000 IU, which suggests intentional supplement intake.
