Now I'm going to answer my own question as a follow-up to Matt's. Okay. So this is how to know
what percent of something in a complex form gives you what percent of the nutrient of interest,
if you ever want to calculate it yourself. So I'm going to share my screen.
So what you want to do, let's say you want to know what percent of
Alpha-GPC is choline. What you want to do is say Alpha-GPC, molar mass
and Google gives it to you right here, 257.221. And then you want to say choline molar mass
104.1708 and so you want to take this number,
the nutrient of interest, and you want to divide it by this number, the dose of the complex form.
And then you would get 0.404985. So to carry it out to two digits that rounds down to 0.4.
Alpha-GPC is 40% choline. And if you want to find amount of choline
in Alpha-GPC, you take the dose of Alpha-GPC and you multiply it by 0.4. Or if you want to
be highly specific, you multiply it by this number and you can do the exact same thing for magnesium
glycinate, iron bisglycinate, et cetera. The only thing that you want to be careful of
is that it does help to look at the structure of something to make sure that there's only one unit
of that nutrient in that complex. So for example, iron bisglycinate, you know from its name that
there is two glycine molecules for every iron and you will have to take that into account
by doubling the contribution of glycine to the weight, but sometimes that's not evident in the
name. And so if something is magnesium glycinate, it helps to Google magnesium glycinate structure,
look at it and make sure that there's only one or if there's two, et cetera. So verify with
the structure that the unit is one-to-one or if it's not double or triple, whatever those two or
three of, but in general divide the molar mass of the nutrient of interest by the molar mass of the
entire complex. Actually you don't necessarily have to do that. If you take the molar mass of
magnesium glycinate, then you don't care whether there's one or two glycine there because you're
not dealing with the molar amounts of glycine. So actually dealing with the molar mass of the
complex versus the molar mass of the nutrient of interest allows you to get around knowing
the structure because the molar mass of the complex should incorporate the information
about how many of each unit or in that complex. All right. I hope that helps anyone who cared
about that because you could ask that question for a thousand different compounds. So there you go.
