From diabetes, neuropathy, depression, MTHRF gene, DHFR gene, cardiovascular disease and methotrexate, learn more about these conditions and vitamin B deficiencies. Folinic-Plus contains vitamins B6, B9, & B12.
Diabetics are at a much higher risk for peripheral neuropathies. In addition, Metformin (still the first-line drug of choice for type II diabetes) can cause B12 deficiency. Please visit the Diabetic Neuropathy page to learn more.

Subgroups of persons with neuropathy have been demonstrated to respond to B6, folates and B12. The studies are of varying quality and results but continue to show benefit. In spite of over 40 years of use, current critical reviews continue to state that mechanisms are not well understood and call for more studies.

Studies going back to the 1960s show an increased incidence of folate deficiency in patients with depression. There appears to be a subset of patients who improve with folate supplementation even when levels test normal. The mechanism is postulated to be improvement in serotonin metabolism which requires B vitamins. Supplementation is also appropriate in any patient with deficiency. Studies have not convincingly demonstrated increased benefit from ultra-high doses of folate.

Folinic acid has been demonstrated to be metabolized efficiently in patients with the most common more severe MTHFR mutation (the C677 →T Mutation).
Conversion of 5-Formyltetrahydrofolic Acid to 5-Methyltetrahydrofolic Acid Is Unimpaired in Folate-Adequate Persons Homozygous for the C677T Mutation in the Methylenetetrahydrofolate Reductase Gene

Folinic acid is a naturally occurring reduced form of folate which does not require the action of dihydrofolate reductase (DHFR) for conversion to its active form.
In spite of high hopes, numerous studies continue to show no appreciable benefit from high-dose folate and B12.

In this third update of the Cochrane review, there were no differences
in effects of homocysteine-lowering interventions in the form of
supplements of vitamins B6, B9 or B12 given alone or in combination
comparing with placebo on myocardial infarction, death

Methotrexate is a cancer drug also commonly used for psoriasis and some forms of arthritis. Folinic acid is often used in patients after methotrexate dosing, but Folinic-Plus®can interfere with the therapeutic effect of MTX. The use of all vitamins, nutritional supplements and herbal products should be discussed thoroughly with the treating physician of anyone who has been prescribed methotrexate.
