Sunlight through glass does not provide Vitamin D

I'm always worried about how easy it would be for manufacturers to accidentally put more in a pill than the label says.

10,000 IU is only 1.25 mg, and vitamins aren't well regulated. It's not like you'd notice if your supplement contained 100,000 IU.

That happens all the time. Please check https://labdoor.com/ before buying any unregulated drug.

USP and other certifications are supposed to address this, but the onus is on the consumer to seek out the certification label.

Others include NSF, UL, and consumerlab

There's still the chance that a manufacturing mistake could result in bad dosage but that applies to all products including medicine.

Vitamin D is particularly worrisome to me because a few milligrams is the difference between therapeutic and toxic.

... and in fact it has happened. With drops for infants that had a 75 times too high concentration:
