Inside this capsule
This capsule
Vitamin B12
Methylcobalamin · 1000 mcg
One ingredient. The dose on the label is the dose in your hand, and the lot number traces it back to one supplier: DSM.
A typical blend capsule
ingredient?dose?ingredient?dose?ingredient?dose?ingredient?dose?ingredient?dose?ingredient?…
“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
B12's role in red-blood-cell formation is an authorised nutrient function. If you take prescription medication, confirm with your pharmacist.

- ★★★★★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.

- ★★★★★Bot understood my mess
I picked three problems at once and it merged them into one set without doubling anything up. It even explained which two ingredients shouldn't be swallowed together.

- ★★★★★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.
