I’m about to start with DIY Soylent, but I have some concerns in regards to calcium and magnesium.
I see that many of the high rated recipes use Now Foods 1000mg calcium and 500mg magnesium tablets. Now Foods states that the magnesium is 80% derived from oxide. My understanding is that magnesium oxide is rubbish and your body will only absorb perhaps 4% of it, meaning that 500mg of oxide would leave you with a massive deficiency.
It’s not clear to me whether the 500mg that Now Foods claims is how much your body will actually absorb, or the weight of the oxide in the tablet. I tend to think it’s the latter as it’s better for marketting, but this is just a guess.
Does anyone have any insight?
