Is this potentially harmful substance lurking in YOUR nutritional supplements?
If you take anything other than the very highest quality, most natural supplements, chances are that this substance – contained in over 90% of supplements and in most pharmaceutical drugs – will feature on the label/s.
You may have seen it there before and, like me, not batted an eyelid, assuming it was a supplemental form of magnesium, and therefore no cause for concern.
But magnesium stearate is not a substance added for your nutrition, nor for any health benefits whatsoever.
It’s machine lube.
No, I’m not kidding, but I wish I was.
Magnesium stearate is what is known in the supplement industry as an “excipient”. These are synthetic substances which are added to enable supplement manufacturers to mass-produce their wares more easily and cheaply. Other examples are titanium dioxide and talcum powder (often listed, simply, as “talc”).
Magnesium stearate is a flow enhancer added so that production machinery will run at maximum speeds, and require minimal cleaning, thereby maximising profits.
And that is the only reason for its presence in nutritional supplements – so that manufacturers can make the highest profits possible when you trustingly invest in, and ingest, their “health” products.
Where magnesium stearate is used in the supplements industry it is only used in tiny quantities. (Or rather it should be – but the industry is grossly underregulated.)
But if you’re taking several capsules every day containing this substance, as many health seekers do, here’s a mini guide to what it is, so you can decide what to do.
Magnesium stearate is manufactured by hydrogenating cottonseed or palm oil – and cottonseed oil has an extremely high level of pesticide residues, due to the fact that cotton crops are heavily sprayed.
