Let’s explore “SLC19A1 & folate transport”

BHMT helps recycle homocysteine into methionine using betaine. It is a different route from the folate and B12 pathway.

GGH encodes gamma-glutamyl hydrolase, which removes glutamate residues from folate compounds. This affects folate handling and helps explain why folate metabolism includes retention and processing as well as intake.

The homocysteine chapters include MTHFD1L in the wider folate-related genetic map.

SHMT1 connects serine and glycine with folate chemistry.

MTHFS encodes an enzyme that converts 5-formyltetrahydrofolate into 5,10-methenyltetrahydrofolate. This places it in folate interconversion; it is not another name for MTHFR or a direct maker of methylfolate.

Explore rs2236225, rs1076991, folate-dependent one-carbon metabolism, nucleotide synthesis, homocysteine, and double homozygosity.

You eat something sweet. Your energy shoots up. Then suddenly you are exhausted, foggy, irritable, and reaching for something else to get you through the day. That cycle deserves a closer look. MTHFR variants can influence folate meta

PURSER WELLNESSWhat is MTHFR? What can YOU do about it?A conversation with Dr. Purser

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.

PURSER WELLNESSWhat Happens If You Have A Gene SNP?A conversation with Dr. Purser

Genetic SNPs are tiny changes in your DNA that can drastically affect how well your enzymes and proteins work. For example, being homozygous for MTHFR C677T leaves that enzyme functioning at only about 30% efficiency, which can drain your energy and impair folate processing. Similarly, errors in SOD genes reduce your body’s ability to neutralize free radicals. While we can’t change your genes, we can work around them by identifying these weaknesses and filling the gaps with targeted nutrition and supplementation—helping your body function closer to its full potential.

PURSER WELLNESSGene Types ExplainedA conversation with Dr. Purser

Your genetic results might list “wild type,” “heterozygous,” or “homozygous,” but what does that mean? Wild type means both copies of your gene are normal, heterozygous means one is normal and one has a change, and homozygous means both copies have the same change. With genes like MTHFR, these variations can affect how efficiently your body processes nutrients like folate—sometimes cutting function by 40–70%—which is why targeted nutrition and testing matter.

PURSER WELLNESSPossible Cause of Crohn's Disease?A conversation with Dr. Purser

Dr. Purser talks about a meta-analysis where correlations are drawn between Crohn's disease, ulcerative colitis, inflammatory bowel diseases, and B12 folate deficiencies. However, it is unclear how each are directly related. PubMed Study: https://pubmed.ncbi.nlm.nih.gov/28406440/ Contact us at (801) 796-7667 or info@danpursermd.com for help.
