The Claim
In adults with prediabetes and hypovitaminosis D, weekly supplementation with 60,000 IU of vitamin D3 for 12 weeks increases serum 25-hydroxyvitamin D levels from an average of 10.1 ng/mL to 52.2 ng/mL and achieves sufficiency in all participants without inducing hypercalcemia.
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.
Adults with prediabetes and low vitamin D levels who take 60,000 IU of vitamin D3 once a week for 12 weeks experience a rise in their blood vitamin D levels from 10.1 ng/mL to 52.2 ng/mL, reaching sufficiency without developing high calcium levels.
See the scientific wording
In adults with prediabetes and hypovitaminosis D, weekly supplementation with 60,000 IU of vitamin D3 for 12 weeks significantly increases serum 25-hydroxyvitamin D levels from an average of 10.1 ng/mL to 52.2 ng/mL, achieving sufficiency in all participants without inducing hypercalcemia.
Taking a high weekly dose of vitamin D3 gets absorbed into the blood, where it is converted into a storage form that builds up over weeks until it reaches a healthy level. The body carefully controls how much of this storage form turns into the active hormone, so calcium levels in the blood stay normal even when vitamin D is high.
What the research says
1 studyThis study gave people with low vitamin D and prediabetes a weekly vitamin D pill for three months, and their vitamin D levels shot up from very low to healthy levels—without any dangerous side effects like too much calcium in the blood.
