FAQ
How much vitamin D is in one capsule?
Each capsule provides 1,000 IU (25 µg) of vitamin D3. The maker allows up to 2 capsules (2,000 IU) daily, but one a day is the standard course this 60-capsule bottle is sized for.
What does “doctor-supervised” mean here?
Dr.Formula is a Japanese supplement line developed with physician supervision by Arkwise, with regular third-party testing declared by the maker. It is still a food supplement, not a medicine.
Is this suitable for vegetarians or halal diets?
The vitamin D3 is derived from sheep-wool lanolin (an animal source, collected from wool), and the capsule shell composition is stated on the package. If you follow a strict vegetarian or halal diet, please review the label before use.
Is this the original Japanese product?
Yes — we sell the Japanese retail version made by Arkwise for the domestic market. We are located in Kobe, Japan and ship every order directly from Japan with tracking.
Can I take it together with other supplements?
Vitamin D is commonly combined with other daily supplements, but if you already take a multivitamin containing vitamin D or any medication, check the total daily amount and consult your doctor or pharmacist first.
