Vitamin D supplementation to prevent acute respirator tract infections: systematic review and meta-analysis of individual participant data.
The patients having serum zinc levels below 70g/dL are considered as zinc deficient.12 This low serum zinc level may be due to hyperzincuria or impaired zinc absorption, as shown in the previous studies.7,13 Studies on humans show the beneficial effects of zinc supplementation in patients with diabetes by improving diabetes complication.14-16 Serum zinc have an impact on HbA1c levels, as our results demonstrate that after three months zinc supplementation HbA1c% is decreased (statistically non-significant) in intervention group as compared to control group.
Conclusion: Vitamin D supplementation decreases the severity of HF as reflected by reduction in serum pro-BNP levels and significant increase in six minutes' walk distance.
Five treatments were evaluated: control (without supplementation), supplementation with nitrogen at 1 g of crude protein (CP)/kg BW, supplementation with 2.5 g of starch (Amisol 3408, CornProducts Co., Santana do Parnaiba, SP, Brazil)/kg BW, supplementation with nitrogen (1 g CP/kg BW) and starch (2.5 g/kg BW), and supplementation with nitrogen (1 g CP/kg BW) and a mixture of corn starch and nitrogenous compounds (2.5 g/kg BW), thereby resulting in an energy part of the supplement with 150 g CP/kg of dry matter (DM).
"The reason we saw improvements in glucose metabolism following vitamin D supplementation in those at high risk of diabetes, or with newly diagnosed diabetes, while other studies failed to demonstrate an effect in people with long-standing type 2 diabetes is unclear.
Markers of insulin function and glucose metabolism were measured before and after six months of high-dose vitamin D supplementation (approximately 5-10 times the recommended dose).
This study supports the clinically relevant benefit of L-carnitine supplementation in lowering the circulating levels of CRP.
Daily or weekly vitamin D supplementation (in doses ranging from < 20 to [greater than or equal to] 50 [micro]g/d) reduced the risk for ARTI (adjusted odds ratio [AOR] = 0.88; 95% confidence interval [CI], 0.81-0.96; number needed to treat [NNT] = 33).
The eligibility criteria used were: articles that presented original data on serum concentration of retinol in infants or concentration of retinol in maternal breast milk of both mothers, both after supplementation. The study was restricted to these groups, since they are more vulnerable to vitamin A deficiency and because they are attended by the supplementation program of this micronutrient.
Selenium levels in the egg white, egg yolk and total egg were documented at several levels of supplementation. Egg production at each level of supplementation was also documented.
The data on the effect of vitamin D supplementation on AD severity "suggested potential benefit but were conflicting," concluded Christina M.
