The Claim
In patients with type 2 diabetes and chronic kidney disease, daily supplementation with 4000 IU of cholecalciferol for three months increases serum 25(OH)D levels from a median of 12.1 ng/mL to 34.5 ng/mL.
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.
In people with type 2 diabetes and kidney disease, taking 4000 IU of vitamin D daily for three months raises blood levels of vitamin D from 12.1 ng/mL to 34.5 ng/mL.
See the scientific wording
In patients with type 2 diabetes and chronic kidney disease, vitamin D supplementation with 4000 IU of cholecalciferol daily for three months significantly increases serum 25(OH)D levels from a median of 12.1 ng/mL to 34.5 ng/mL, demonstrating that standard supplementation can correct deficiency in this population despite impaired kidney function.
When a person takes vitamin D pills, the body converts it into a form called 25(OH)D in the liver. Even when the kidneys are damaged, enough of this form still builds up in the blood because the liver can make it without help from the kidneys. Some people have too much of a protein that traps vitamin D, making it harder to absorb, but high doses of vitamin D overwhelm this trapping effect and still raise blood levels.
What the research says
1 studyGiving 4000 IU of vitamin D daily for three months raised vitamin D levels from very low to normal in most people with type 2 diabetes and kidney disease, even though their kidneys weren’t working perfectly. Some people didn’t respond as well because of a protein in their blood, but most still got better.
