Conclusion Although , serum 25(OH)D concentrations after supplementation reached sufficiency was observed , muscle strength did not significantly improve at this point of current meta- analysis .
Background The purpose of this systematic review and meta- analysis is to investigate the effects of vitamin D3 supplementation on skeletal muscle strength in athletes .
Vitamin D3 supplements or vitamin D3 fortified foods always have cl aims for bringing people health benefits including bone and muscle health .
An up-to- date rigorous systematic review and meta- analysis is important to better underst and the effect of vitamin D3 supplementation on muscle strength .
Vitamin D and health in pregnancy, infants, children and adolescents in Australia and New Zealand: a position statement.
• The recommended level for serum 25-hydroxyvitamin D ( 25(OH)D ) in infants , children , adolescents and during pregnancy and lactation is ≥ 50 nmol/L. This level may need to be 10 - 20 nmol/L higher at the end of summer to maintain levels ≥ 50 nmol/L over winter and spring . • Sunlight is the most important source of vitamin D. The US recommended dietary allowance for vitamin D is 600 IU daily in children aged over 12 months and during pregnancy and lactation , assuming minimal sun exposure . • Risk factors for low vitamin D are : lack of skin exposure to sunlight , dark skin , southerly latitude , conditions affecting vitamin D metabolism and storage ( including obesity ) and , for infants , being born to a mother with low vitamin D and exclusive breastfeeding combined with at least one other risk factor . • Targeted measurement of 25(OH)D levels is recommended for infants , children and adolescents with at least one risk factor for low vitamin D and for pregnant women with at least one risk factor for low vitamin D at the first antenatal visit . • Vitamin D deficiency can be treated with daily low-dose vitamin D supplements , although barriers to adherence have been identified . High-dose intermittent vitamin D can be used in children and adolescents . Treatment should be paired with health education and advice about sensible sun exposure . Infants at risk of low vitamin D should be supplemented with 400 IU vitamin D₃ daily for at least the first year of life . • There is increasing evidence of an association between low vitamin D and a range of non-bone health outcomes , however there is a lack of data from robust r and omised controlled trials of vitamin D supplementation
