Micro Ingredients Vitamin D3 10
Checked against public sources on July 25, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Vitamin D: 250 mcg on the label; adult upper limit 100 mcg. This serving is about 2.5× the adult upper limit shown by NIH. The limit applies to adults; 100 mcg = 4,000 IU.
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

What is worth knowing.
Headlines first. Open evidence only when you want the source trail.
Vitamin D: 250 mcg on the label; adult upper limit 100 mcg.
This serving is about 2.5× the adult upper limit shown by NIH. The limit applies to adults; 100 mcg = 4,000 IU.
Evidence and sources
The panel lists 250 mcg vitamin d. NIH gives 100 mcg as the adult Tolerable Upper Intake Level for adults; 100 mcg = 4,000 IU. That is about 2.5 times the limit.
Locked evidence record →Open the full source-linked findingListing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 0.2 mg; the photo-read Supplement Facts panel shows Vitamin K2 (as menaquinone-7)(MK-7) at 0.2 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
