L-5-MTHF 1700 mcg - 120 Capsules

6S] isomer, which is why DFH provides 5-MTHF as this natural isomer rather than the mixed (or racemic) form. Our L-5-MTHF uses the patented folate derivative Quatrefolic®.  This innovative form of folate has demonstrated high bioavailability and solubility as well as long-lasting stability. Quatrefolic® L-5-MTHF helps to increase blood folate levels much better than folic acid.  L-5-MTHF should be used when high doses of folate are needed. Individuals who have tested homozygous with either the A1298C or C677T MTHFR mutation, or those with elevated homocysteine levels, should be using L-5-MTHF as the preferred form of folate supplementation. This will be more effective for them than other forms of folic acid or folates.  Others who may benefit from L-5-MTHF: Pregnant women and women wishing to become pregnant who have a familial history of depression, high homocysteine levels, or genetic defect in MTHFR. Note: All pregnant women should take Prenatal Pro™ as their comprehensive multivitamin; can combine with L-5-MTHF if higher levels of folate are needed. Women with abnormal pap smears (precancerous) Those with very high homocysteine levels not responding quickly to Homocysteine Supreme™(consider using them together) Dialysis patients Organic acid testing that reveals elevated FIGLU (marker used to identify folate deficiency) Patients with family history of dementia/vascular dementia Patients with depression Long-term alcoholism Long-term use of oral contraceptives, and persistent use of medications to lower folate levels, including high doses of NSAIDs such as aspirin or ibuprofen; anticonvulsants (phenytoin, phenobarbital, and primidone); trimethoprim (antibiotic), pyrimethamine (antimalarial), triamterene (blood pressure med.) and sulfasalazine (treatment for ulcerative colitis).
