The Claim
Vitamin D supplementation in overweight and obese children and adolescents has no significant effect on body mass index (BMI), fasting blood sugar, insulin, HOMA-IR, QUICKI, triglycerides, total cholesterol, or LDL-C levels.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Giving vitamin D supplements to overweight or obese children and teens does not change their body mass index, blood sugar, insulin levels, or cholesterol levels.
See the scientific wording
Vitamin D supplementation in overweight and obese children and adolescents does not significantly improve body mass index (BMI), fasting blood sugar, insulin, HOMA-IR, QUICKI, triglycerides, total cholesterol, or LDL-C levels, based on a meta-analysis of nine randomized controlled trials involving 440 participants over 6 to 26 weeks.
When overweight children take vitamin D supplements, the vitamin gets trapped in their fat tissue, so not enough reaches the organs that need it to regulate blood sugar and cholesterol. Without enough vitamin D in the bloodstream, the receptors that control insulin and glucose use stay inactive, so blood sugar and insulin levels stay high, and fat and cholesterol levels do not improve.
What the research says
1 studyGiving vitamin D pills to overweight kids and teens didn't help lower their weight, blood sugar, or bad cholesterol, according to a review of nine studies. So, vitamin D supplements don't seem to fix these health issues in this group.
