What is MTHFR? What can YOU do about it?

Some search terms matched

MTHFR is one of the most studied genetic SNPs, with the two main variants being C677T and A1298C. These changes reduce the body’s ability to process folate and make energy, leaving people exhausted and deficient in key nutrients. Specialized folates, B12 forms, and glutathione can bypass the blockages, and products like MTHFR Daily were designed specifically to fill these nutrient gaps so patients can restore energy and thrive.

AUTSIM - What is a potential ROOT CAUSE of Autism? Can it be helped?

Some search terms matched

What I see again and again is an inability to detox caused by failures in the Transsulfuration Pathway. This is your pathway that converts homocysteine to glutathione. If you have MTHFR or 16 other Gene SNPs, you will have problems with this pathway.

Homocysteine is the Secret Assasin

Some search terms matched

Homocysteine is nasty — but here’s the truth no one tells you. It doesn’t kill you directly — it triggers white blood cells to release IL-8 and MCP-1, causing inflammation, kidney failure, heart attacks, and strokes. Most doctors don’t even check it anymore, thinking there’s no fix. But there is. Whether from 17 genetic SNPs or 12 vitamin deficiencies (like B6 or B12), you can address it by supporting your body’s ability to convert homocysteine into glutathione.
