I''m going to be trying up to 350 mg capsules of biotin
I had made up 50 size 1 capsules of biotin. They weighed out to about 230 mg. I say about, because each capsule varied quite a bit. Some might not even have weighed as much as 200 mg whilst others might have been more than 250 mg. It was all a matter of how compressed or how full the capsules were.A few weeks ago, I purchased a size 0 capsule filling capping gadget. A few hours ago, I filled another 50 capsules with pure biotin. This time they are size 0 caps rather than size 1. After filling, I weighed as few of them. They are all well over 300 mg.
