Jarrow Formulas Methyl Folate 400 mcg
Brand: Jarrow Formulas · Form: CAPSULE [E0159]
Our assessment
Our assessment: The evidence shows that methyl folate is a well-absorbed form of vitamin B9, but the data provided here is for the ingredient calcium, not methyl folate. For this specific product, Jarrow Formulas Methyl Folate 400 mcg, we must rely on the general data for calcium as a reference point for supplement safety, though it is not directly applicable to folate. You should be aware that calcium can be beneficial for bone health, but high intakes from supplements may carry risks [NIH ODS].
How it works
Think of calcium as a master regulator for your bones and nerves. It supports bone mineralization and density, and it helps with muscle relaxation and nerve signaling [NIH ODS]. While this mechanism applies to calcium, methyl folate works differently by supporting DNA synthesis and red blood cell formation. Data for folate's specific mechanism is not available in this dataset.
Safety profile
The FDA received a total of 592,059 adverse event reports for all dietary supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. These side effects are not specific to methyl folate, and data on side effects for this product is not available.
Our recommendation
Our recommendation: Since the data provided does not include specific information on methyl folate, you should consult your healthcare provider before starting this supplement. For calcium, the data suggests you should be cautious with high doses from supplements. If you have concerns about interactions, note that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. For methyl folate specifically, we cannot make a recommendation without more data.
