PlexusDx Methylation Support Diet

The PlexusDx Methylation Support Diet is a specialized nutritional approach designed to optimize the methylation cycle—a critical biochemical process that fuels detoxification, DNA repair, energy production, and neurotransmitter balance. This plan is particularly beneficial for individuals whose PlexusDx report indicates variants in key methylation genes such as MTHFR, MTR, MTRR, BHMT, or PEMT. These genetic variations can sometimes affect how efficiently your body processes specific nutrients, potentially slowing down the conversion of homocysteine into methionine. To counter this, this diet focuses on "real-world restrictions" and strategic inclusions, specifically targeting Dietary Folate, Vitamin B12, Riboflavin, and Choline. By emphasizing whole-food sources of these nutrients—such as dark leafy greens for natural folate and eggs for choline—this plan aims to bypass potential genetic bottlenecks and support optimal cellular function naturally.

Research suggests that supporting the methylation pathway requires more than just avoiding "bad" foods; it involves actively fueling the enzymes that drive your biochemistry. For example, the MTHFR enzyme requires Riboflavin (B2) to function, while the BHMT gene uses Choline to recycle homocysteine through a secondary "backdoor" pathway. The recommendations below focus on providing these co-factors in their most bioavailable forms to help maintain balance.

Prioritize natural folate: Focus on dark leafy greens (spinach, kale), asparagus, legumes, and avocados rather than foods fortified with synthetic folic acid, which some genes process less efficiently.
Boost Choline and Betaine intake: Include eggs (especially the yolks), liver, quinoa, and beets to support the BHMT pathway and reduce the burden on folate-dependent processes.
Ensure adequate B12 and Riboflavin: Consistently eat lean meats, fish, poultry, and almonds to provide the essential co-factors needed for MTR and MTRR enzyme activity.
Reduce methylation burdens: Limit alcohol and highly processed foods, as these deplete B-vitamins and increase the demand on your detoxification and methylation systems.

Your custom meal plan is already loaded with recipes that match these principles, but you can easily tailor it further to fit specific needs (like gluten-free, dairy-free, or soy-free) using our meal planning tool. Click the button below to access your plan and use the "Swap" feature to customize your week:

Locate the meal you want to change on your calendar.
Click the three dots (...) on the recipe card.
Select “Swap recipe” from the dropdown menu.
Choose “Swap” (for just that meal) vs “Swap all” (for all instances of that meal).
Keep clicking “Swap” to find alternatives that match plan rules like GF/DF/egg-free.
