"I noticed a change in my energy levels and clarity with the methylated vitamins."

The Challenge

Krystal chose the Functional Health Genetic Test because she wanted the most comprehensive view of her genetics available. She was particularly curious about her MTHFR status — a concern she had after learning that folic acid is routinely added to processed foods like tortillas, and that people with certain MTHFR variants may not process synthetic folic acid efficiently. She was already taking magnesium glycinate and omega-3, and wanted to know whether her current routine was truly matched to her biology — or just good guesses.

What the Test Revealed

The Functional Health Genetic Test delivered a gene-by-gene breakdown of Krystal's methylation profile, including her MTHFR status. The report not only validated the supplements she was already taking — magnesium glycinate and omega-3 — but also identified an opportunity she was missing: methylated vitamins. Standard B vitamins weren't the right form for her genetics. The report also included meal recipes she found simple to follow and easy to customize around her lifestyle.

What Changed

Krystal made focused adjustments to her existing supplement routine based on her results:

  • Added methylated vitamins on top of her existing regimen, replacing standard forms of key B vitamins
  • Continued magnesium glycinate and omega-3, now confirmed as appropriate for her genetic profile
  • Began following the personalized meal recipes from her Results Portal

The Outcome

The shift to methylated vitamins made a noticeable difference. Krystal observed a clear change in both her energy levels and mental clarity — an outcome she directly attributed to the switch. Her existing supplements had been reasonable choices, but the test helped her close the gap between a general routine and one genuinely aligned with her genetics. She now recommends the test to anyone interested in optimizing their health through diet and targeted supplementation.

In Their Own Words

"I went with the functional health test because it had the most information and was not disappointed. I loved the breakdown of each gene. I was curious to see if I had the MTHFR because they are putting folic acid into tortillas. I recommend this to anyone who is interested in optimizing health with supplements and diet. The meal recipes are simple to follow and easy to customize. I started to take methylated vitamins on top of some supplements they suggested like magnesium glycinate and omega-3 that I was already taking. I noticed a change in my energy levels and clarity with the methylated vitamins."

Frequently Asked Questions

Why does MTHFR status matter for people who consume processed foods with added folic acid?

Many processed foods — including breads, tortillas, and cereals — are fortified with synthetic folic acid. People with MTHFR variants may process this form of folate less efficiently than those without the variant. Over time, this difference can affect methylation function, energy metabolism, and nutrient balance. Understanding your MTHFR status, as Krystal wanted to, helps you make more informed decisions about both the foods you eat and the supplement forms you choose — particularly whether methylated folate is more appropriate for you than standard folic acid.

What is the difference between standard B vitamins and methylated vitamins?

Methylated vitamins are forms of B vitamins — particularly B12 and folate — that are already in their active, bioavailable state. Standard forms require the body to convert them before they can be used, a process that depends in part on MTHFR enzyme function. For people whose genetics affect this conversion pathway, methylated forms may be more readily absorbed and utilized. Krystal's experience — noticing improved energy and clarity after switching to methylated vitamins — reflects what many customers with MTHFR-related variants report once their supplement protocol is aligned with their genetics.
