Questions, answered
Vitamin D3 (Cholecalciferol) FAQ
- How much vitamin D3 is in Ova Balance?
- Each sachet contains 600 IU (15 mcg) of vitamin D3.
- Is 600 IU the same as 15 mcg?
- Yes. One microgram of vitamin D equals 40 IU, so 15 mcg equals 600 IU.
- Does this research prove Ova Balance improves PCOS or fertility?
- No. These sources describe vitamin D and vitamin D status. They are not clinical trials of the finished Ova Balance formula or proof of PCOS or fertility benefits at 600 IU.
- Is this vitamin D3 vegan or liposomal?
- Those properties depend on the ingredient source and delivery system. Check the final label or contact TruWe for source details; this page makes no vegan or liposomal claim for the vitamin D3.
Ingredient-level research is published on the individual actives and their delivery forms. It describes the ingredients, not a finished-product claim. These statements have not been evaluated by the FSSAI or FDA. This content is for information only and is not medical advice.
