Frequently asked questions
Questions about Vitamin D3
How much Vitamin D3 should I take daily?
The Endocrine Society recommends 1,500–2,000 IU daily for adults at risk of deficiency. PeakFusion Vitamin D3 provides 2,000 IU per label, independently verified at approximately 2,556 IU per softgel.
What is the difference between Vitamin D3 and Vitamin D2?
D3 (cholecalciferol) is the form synthesized in human skin and is significantly more effective at raising serum vitamin D levels than D2 (ergocalciferol). Research shows D3 is approximately 87% more effective than D2 at equivalent doses. PeakFusion uses D3 only.
When should I take Vitamin D3?
Take with a meal containing fat. Vitamin D3 is fat-soluble, meaning dietary fat significantly improves absorption. Morning or evening with a meal both work equally well — daily consistency is what matters.
How do I know if I am Vitamin D deficient?
Deficiency is common in athletic populations, with research finding rates of 35–70% in certain groups, particularly among indoor athletes and those in northern latitudes. A 25(OH)D blood test through a healthcare provider is the only accurate way to assess your status.
What was the verified dose per softgel?
Lot VS220698 was independently verified at approximately 2,556 IU per softgel against a 2,000 IU label claim. Full test results are publicly available on our lab results page.
