Helps enzymes, nerves and muscles work, and participates in energy production.

THE TEACHING CONNECTION

A cofactor across several systems

A cofactor across several systems

Dr. Purser’s course places magnesium in energy, muscle, nerve, sleep and insulin-related discussions. It teaches minerals as enzyme cofactors: a finding can connect to several functions without proving that magnesium is the single cause of every symptom.

Putting the pieces together

The combined Genetic/CMA approach brings magnesium together with inositol, B vitamins, amino acids and redox findings when reviewing nervous-system sensitivity. Current use and tolerance matter, and the plan should account for duplicate ingredients and medication or kidney-related considerations.

How supplementation is approached

Dr. Purser uses magnesium across energy, muscle, nervous-system and metabolic patterns when indicated. Compare the elemental amount and formulation rather than just the capsule count. Check existing electrolyte, sleep and multivitamin products before adding more.

Food sources

Pumpkin seeds; almonds; spinach; beans; whole grains.

Supplement forms

Citrate, chloride, oxide and glycinate are examples. The label reports elemental magnesium.

A question to bring to your visit

Which current findings make magnesium a priority, and how will we distinguish its effects from other changes?

What to track and reassess

Track bowel tolerance and the specific muscle, sleep or energy goal. Kidney disease and medicines that need spacing from minerals should be reviewed before changing the amount.

From starting support to follow-up

If you and your clinician start a CMA replenishment plan, you may add one new product at a time, often waiting 3–7 days to see how you feel. A check-in is usually planned near ten weeks during an approximately 100-day period. Follow your written plan for amounts and timing. At follow-up, you may continue, change, or stop each item. This timetable does not automatically end longer-term support.
