Hi

No personal knowledge or experience. I had a Google. There are a number of bits of published research around which might indicate that there is some impact on blood glucose levels related to raising folate or folic acid levels. This is just one, pulling together a number of studies.


So - according to this, some reduction in fasting BG levels, fasting insulin and HOMA-IR (insulin resistance), no impact on HbA1c. They say: "Folic acid supplementation significantly reduces some markers of glycemic control in adults. These reductions were small, which may limit clinical applications for adults with type II diabetes. Further research is necessary to confirm our findings".

Studies have looked at whether low folate can cause high BG. This is one, from China (some Chinese research may be suspect) and on mice, not humans.


This is a meta analysis of a number of RCTs:

The overall take is that there appears to be something going on relating folate to blood glucose but "more research is needed."
