Did you know that you might not be healing from your injuries or from COVID because of poor methylation? The good news is that there are steps you can take to improve your methylation, which is directly related to recovery and performance.
Methylation refers to the donating of an active methyl group between molecules. A methyl group is a protein that consists of three hydrogen atoms attached to one carbon atom. Methylation is required for many metabolic processes, as you can see in the table below. Each of the functions in the left column require methylation.
Over 50% of the population has impaired methylation. This means our bodies cannot donate that active methyl group between molecules.
What are some of the effects of impaired methylation?
What causes us to be poor methylators? Much like everything else, it’s partly the hand of cards you’re dealt (genetics) and partly how you play them (the environmental factors).
First, let’s talk about things over which we have control: environmental factors.
One environmental cause is nutrient deficiency. Methylation pathways require specific nutrients. If they are inadequate, we cannot methylate properly.
B12 and folate are highlighted as they are two of the common deficiencies. Interestingly, people who eat healthy, whole food diets are more likely to be deficient in folate as they are not eating fortified foods.
Methylation is also impaired by environmental toxins, high estrogens, acute or chronic stress, chronic infection, immune challenge, mast cell activation syndrome (MCAS) and histamine intolerance.
Certain medications will also impair methylation including oral contraceptives, proton pump inhibitors (PPIs), antibiotics, nitrous oxide, cholestyramine and valproic acid.
Genetic single nucleotide polymorphisms (SNPS) can lead to reduced methylation capacity. Many people have heard of the MTHFR SNP, present in about 40% of the population. Homozygous MTHFR can diminish methylation by up to 75%. There are many other SNPs with varying levels of diminished enzyme activity.
You can’t change your genes but you can optimize your methylation. There are high dose methyl-donor supplements you can take, however we don’t know the long-term effects. They have been associated with possible immune dysfunction.
Ideally, supplementing with 5-MTHF at a dose of 200mcg-400mcg per day is a good start. Additionally, and more importantly, we should be eating foods that support methylation.
The table below shows foods that support methylation. The foods in ALL CAPS are the most important. Organ meats and fish are great nutrient dense foods to support your methylation.
What is it you plan to do with your one wild and precious life?
