Thorne 5-MTHF 5 mg
Brand: Thorne · Form: CAPSULE [E0159] On Market
Our assessment
Our assessment: Thorne 5-MTHF 5 mg provides a highly bioavailable form of folate. The data confirms that 5-MTHF is the active form of folate, which your body can use directly without needing to convert it [NIH ODS].
How it works
Think of 5-MTHF as a key metabolic helper — it is essential for DNA synthesis, cell division, and the production of red blood cells [NIH ODS]. For you, this means it supports processes that are critical during periods of rapid growth, such as pregnancy, and for maintaining healthy homocysteine levels [NIH ODS].
Safety profile
Data not available on adverse event reports specific to this product from the provided FDA data. General folate supplementation is considered safe at recommended intakes, but high doses can mask a vitamin B12 deficiency [NIH ODS]. The Tolerable Upper Intake Level for folate from supplements is 1,000 mcg (1 mg) per day for adults, and this product provides 5 mg, which is above that level [NIH ODS].
Our recommendation
This supplement should only be used under medical supervision, as the 5 mg dose is therapeutic and exceeds the general RDA. Do not take this product without first consulting your healthcare provider to determine if such a high dose is appropriate for your specific health needs [NIH ODS].
