Whilst observational studies have consistently reported associations between low serum concentration of 25-hydroxyvitamin D (25(OH)D) and susceptibility to ARTIs, results of randomised controlled trials to determine whether vitamin D supplementation
can decrease the risk of ARTIs have been conflicting.
When dosage of 660 mg/day zinc was studied in different countries like in Bangladesh by Hayee MA,24 in India by Gupta R,25 and in Israel by Raz I,26 FBG reduction was again uneven, showing disparate response to zinc supplementation
Therefore this study was carried out to see the role of vitamin D supplementation
on physical status of patients suffering from Congestive heart failure (dilated cardiomyopathy).
The nitrogen supplement lacked carbohydrate content, thereby allowing the supplementation
effects with nitrogen to be evaluated without any supplementary source of fiber or energy interfering with the measurements.
"Type 2 diabetes and prediabetes are a growing public health concern and although our results are promising, further studies are required to confirm our findings, to identify whether some people may benefit more from this intervention, and to evaluate the safety of high-dose vitamin D supplementation
in the long term.
Although only 46 per cent of study participants were determined to have low vitamin D levels at the start of the study, supplementation
with vitamin D significantly improved the action of insulin in muscle tissue of participants after six months.
In 2018, carried out a systematic review and meta-analysis of eight randomized controlled trials which showed greater improvement in CRP levels following zinc supplementation
Vitamin D supplementation
in people with circulating levels of 25-hydroxyvitamin D [greater than or equal to] 30 ng/mL did not appear to provide benefit (AOR = 0.96; 95% CI, 0.78-1.18).
To evaluate the effect of vitamin A supplementation
was elaborated a table with the main studies findings, which were extracted in duplicate by the authors, allowing them to discuss the doubts and disagreements found.
As shown in Figure 1, dietary supplementation
with selenium enriched yeast significantly increased egg white selenium levels (P < 0.05).
SRU and/or NSC supplementation
to groundnut straw had a positive effect on BWG on both sheep and goats (Pa$?0.001) (Table 2) The daily DMI and nutrient digestibility pattern are presented in Table 4.
The randomized controlled trial of vitamin D supplementation
used lower SCORAD cut-offs for the different severities of AD, which complicated interpretation the results, "as it may indicate that the severities reported in these articles were exaggerated as compared to other studies," they wrote.
