✅ Final Tips Before Supplementing

• Always consult your healthcare provider before starting any supplement.

• Start with a low dose, especially if you're new to magnesium.

• Look for supplements labeled "highly bioavailable" for better absorption.

• Consider timing: energizing forms (e.g., malate, L-threonate) are best taken in the morning; relaxing forms (e.g., glycinate, citrate) are ideal in the evening.
