Inside this capsule
This capsule
Vitamin D3
Vegan, from lichen · 2000 IU
One ingredient. The dose on the label is the dose in your hand, and the lot number traces it back to one supplier: ESB (lichen D3).
A typical blend capsule

“Proprietary blend, 1,200 mg” — many names, one number, no way to know how much of anything you took, or what competes with what inside.
On the evidence
Vitamin D's roles in immunity and bone maintenance are authorised nutrient functions.

◎ Pairs well with Calcium
Vitamin D drives active calcium absorption in the gut. → Same meal works in your favour. (NIH ODS Calcium Fact Sheet)
◎ Pairs well with Vitamin K2
D3 raises calcium availability; K2 activates the proteins that direct it toward bone. → Take together with a meal containing fat. (NIH ODS Vitamin K Fact Sheet)

- ★★★★★The certificate thing is real
Typed the lot number from my box into the site and the lab report actually opened. First supplement brand where I could do that. Capsules are small enough to swallow easily.

- ★★★★★Clean label, fair price
Compared with what I was paying at a local chemist for a branded version, this works out cheaper per day and the form is better. Import took a while but was handled for me.

- ★★★★★Product fine, wish for more sizes
No complaints on quality — certificate checked out, delivery on time. Three stars because I wanted a smaller trial size before committing to 30 days.
