Purser Wellness Unique Case Success Stories

Some search terms matched

One of the most powerful success stories at Purser Wellness came from a young patient who went from having 3–5 seizures a week to none for three months after completing CMA and genetic testing. In another case, a woman with almost no measurable niacin in her system saw her seizures stop within two weeks once her deficiency was corrected. These aren’t “cures” in the traditional sense—just treating obvious nutritional deficiencies revealed by precise testing—but the results can be life-changing.

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.

😴 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.
