251: How to Calculate the Amount of a Nutrient in a Complex

Masterjohn Q&A Files Episode 251


Question: How to Calculate the Amount of a Nutrient in a Complex

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 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.
