THE TEACHING CONNECTION

From a laboratory flag to a useful plan

From a laboratory flag to a useful plan

Start with your original CMA report: check its date, values, and the lab’s categories. Several low amino acids may raise questions about protein intake or absorption; antioxidant findings may lead to other questions. A flagged result starts a conversation. It does not explain your symptoms by itself.

Putting the pieces together

Your plan may set priorities, avoid doubling up on ingredients, and track food intake and tolerance. Dr. Purser sometimes uses an approximately 100-day replenishment period with a check-in around ten weeks. Your progress may take a different course, so agree on what to track and when to review it.

A question to bring to your visit

What is the first priority, what will I track, and when will we decide whether the plan is helping?

Reading your own results

Bring your original report, current results, health history, and medicines to your visit. This information can help you ask questions, but it cannot diagnose a condition or choose a supplement dose for you.
