5-MTHF is an active, tissue-ready form of folate. It’s an essential B vitamin that supports healthy methylation, fetal development, positivity, and cardiovascular and nerve function.*
Greater Absorption
Thorne’s 5-MTHF includes an active ingredient that is tissue-ready and in its most bioavailable form for better absorption.* |
Well-Researched Benefits
A greater blood level of 5-MTHF (active folate) is achieved after supplementation with 5-MTHF compared to folic acid supplementation.* |
Well-Researched Benefits
In conjunction with vitamin B12, 5-MTHF functions as a methyl-group donor, which facilitates the conversion of the undersirable amino acid homocysteine to the more desirable methionine.* Methyl-group donation is vital to many necessary biochemical conversion processes, including the synthesis of serotonin, melatonin, and DNA.* |

Sourcing Exceptional Ingredients
We develop better standards for higher quality ingredients. Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility – and ultimately better health. |
Manufacturing the Right Way
We manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States. Our Charleston, SC facility is third-party certified. |
Four Rounds of Testing
We perform four rounds of testing for each product we manufacture – far above the industry standard. Thorne has invested in two state-of-the-art in-house laboratories that enable us to conduct four rounds of testing, including raw material testing, in-process batch testing, finished product testing, and expiration date stability testing for each lot of product that we manufacture. |
Thinking Sustainably
We’re thinking sustainably to protect our environment. We believe the environment should never be compromised for the sake of business gain. At Thorne, we believe that doing our part to protect the environment and its most valuable resources goes hand in hand with our product quality standards. |
