Moreover, the effects did not vary by baseline serum 25(OH)D levels or whether participants took the trials omega-3 supplement in addition to vitamin D. However, another clinical trial designed to investigate bone fracture risk found that 800 IU/day vitamin D3 (with or without calcium) or a placebo in 5,292 adults aged 70 years and older for a median of 6.2 years offered protection from cardiac failure, but not myocardial infarction or stroke [125]. Together with calcium, vitamin D also helps protect older adults from osteoporosis. Signs and symptoms of osteomalacia are similar to those of rickets and include bone deformities and pain, hypocalcemic seizures, tetanic spasms, and dental abnormalities [45].

In this procedure, part of the upper small intestine, where vitamin D is absorbed, is bypassed, and vitamin D that is mobilized into the bloodstream from fat stores might not raise 25(OH)D to adequate levels over time [66,67]. However, a meta-analysis of 7 cohort studies that included 7,808 men with prostate cancer found higher 25(OH)D levels to be significantly associated with lower mortality rates from prostate cancer or any other cause [115]. A collaborative analysis of individual participant data from 19 prospective studies assesses circulating vitamin D and prostate cancer risk. Hypercalcemia, in turn, can lead to nausea, vomiting, muscle weakness, neuropsychiatric disturbances, pain, loss of appetite, dehydration, polyuria, excessive thirst, and kidney stones. In contrast to observational studies, clinical trials provide little support for the benefits of vitamin D supplementation for glucose homeostasis. Obesity does not affect the skins capacity to synthesize vitamin D. However, greater amounts of subcutaneous fat sequester more of the vitamin [1].
