CMA and Genetics Jus

Some search terms matched

CMA testing shows the vitamin deficiencies happening inside your cells, while genetic testing reveals why they’re happening in the first place. Patients often find their symptoms match exactly what the CMA shows, and when paired with genetic results, the root causes become clear. In most cases, it’s the genetic errors that drive the deficiencies—not the other way around—making the combination of both tests powerful for finding lasting solutions.

What To Do For Iron Deficiency?

Some search terms matched

If iron transfusions and pills aren’t working, the problem might be B vitamin deficiencies. Without enough B vitamins (like choline, biotin, or folate) or vitamin C, your body can’t absorb iron properly. Fixing these first can often restore iron levels within a few months.

Tired all the time? Are you Overmethylating?

Some search terms matched

😴 Feel like you took 3 Dramamine but all you had was a vitamin? You might be overmethylating—especially if you're taking too much MTHFR support like methylated B vitamins. If you’re drowsy, foggy, or exhausted, it’s time to back off, not push through. Try dropping to 1 capsule of MTHFR Daily and adjust slowly. Your body will thank you.

Treating Homocysteine May Treat The WORLD!

Some search terms matched

Doctors have spent decades trying to lower homocysteine with B6, B12, folate, or $12,000/month injections. But it’s not the homocysteine doing the damage—it’s the IL-8 and MCP-1 cytokines it releases. That’s where glutathione (especially VARS or Glutaryl) changes the game. We’ve seen cytokine levels drop to zero—and symptoms vanish.
