Hi Rachael,Hi,
What do you mean by "uses only MTHF"?
Do you know other companies that produce nutrition supplements without vegetable stearate? Does the quantity in a single capsule significant in lowering the intestine's absorbtion?
MTHF is the same as methylfolate. MTHF is an acronym for methyltetrahydrofolate. I'm just saying they don't use any other forms of folate than methylfolate (such as folic acid, folinic acid, calcium folinate etc.).
The only two companies I have found that do not use stearate are Thorne and Pure Encapsulations. The claim is that stearate does lower the absorption of vitamins in the intestines. I've heard 40% reduction, but I don't remember the source. Someone else might have more current and accurate information.
I've also read some other heath issues with stearates. It would be interesting to start a thread on magnesium stearates and see what others have determined in that regard.
Blessings
Linda
