Dr. Purser discusses interleukins and oxidative stress in cystic fibrosis lung disease.

If you’ve been struggling with severe chronic fatigue, unexplained anxiety, or cardiovascular red flags, your genes might be trying to tell you something. Millions of patients walk out of traditional clinics with normal blood tests, only to be told their crippling symptoms are "all in their head." If you carry the C677T variant, you aren't crazy—you are dealing with a breakdown in cellular biochemistry. The Problem With Synthetic Folic Acid The standard advice from standard doctors is to take synthetic folic acid. For someone with the C677T genetic mutation, this is disastrous. Your enzyme pat

PSEN1 encodes a presenilin protein that participates in gamma-secretase, a protein-processing complex. Some pathogenic variants can cause familial Alzheimer’s disease; a listed common marker is not equivalent to that diagnosis.

PSEN2 encodes a presenilin protein that participates in gamma-secretase, a protein-processing complex. Some pathogenic variants can cause familial Alzheimer’s disease; a listed common marker is not equivalent to that diagnosis.

CXCL13 is a chemokine that attracts cells expressing CXCR5, including B cells. This pairing helps organize immune-cell traffic in lymphoid tissues and some chronic inflammatory settings.

F9 encodes coagulation factor IX. Disease-causing variants can result in hemophilia B, an inherited bleeding disorder, but a panel marker is not equivalent to a confirmed disease-causing finding.

Homocysteine rarely gets the attention of cholesterol, blood sugar, or blood pressure. It should. When homocysteine becomes elevated, it has been associated with cardiovascular disease, stroke, cognitive decline, blood clots, and other he

Why elevated soluble IL-2 receptor levels drive chronic inflammation and pain in sarcoidosis — and what actually helps quiet the fire

🌾 Why has gluten intolerance exploded since the 1970s? It’s not just the bread. In my latest blog I lay out the clear timeline: Roundup (glyphosate) was introduced in 1974… and the rise in celiac disease and gluten sensitivity has tracked

Scurvy may sound like a relic of the past, but this physician is still diagnosing it today. Nutrition gaps, restrictive diets, and heavily processed foods can leave people with bleeding gums, chronic fatigue, unexplained pain, bruising, and

Discover how a common genetic variant in the PEMT gene can block your body’s ability to make phosphatidylcholine — leading to chronic pancreatitis, even if you’ve never touched alcohol.

PQQ, CoQ10, and Vars Glutathione are the ultimate antioxidants you’re missing in your life, so read on to understand why you or a loved one might be struggling with chronic fatigue, weak immune system, and anxiety/depression! • • • • • • •
