Folate / folic acid supplements with the fewest additives

Folate and folic acid (occasionally also called pteroylglutamic acid, vitamin B9, or folacin) may fight birth defects, lower homocysteine levels, and more. However, many folate / folic acid supplements contain more than just folic acid. For example, silica or silicon dioxide are often added to prevent caking, magnesium stearate / stearic acid for easier manufacturing and lecithin, as an emulsifier.

I try to avoid these additives because they may have questionable health effects, and I'd suggest the folate form rather than folic acid for better safety:

In the UK?

I'm not aware of a company that will ship Metabolic Maintenance anywhere but the US/Canada/Australia, so I'd suggest trying one of these UK-based products. These are both the folic acid form, I don't know of an ideal UK-based folate option. Please let me know in the comments if you do.
