Lecture Notes: Magnesium and Magnesium Glycinate

Importance of Magnesium

  • Magnesium is an essential mineral involved in over 350 biochemical processes in the body.
  • It is the fourth most abundant mineral in the human body.
  • Key roles include:
    • Regulating blood pressure
    • Normalizing heartbeat
    • Ensuring proper nervous system function

Magnesium Deficiency

  • Nearly 70% of the US population doesn't get enough magnesium from their diet (National Institute of Health).
  • Recommended dietary intake:
    • Men: 400-450 mg/day
    • Women: 300-350 mg/day

Magnesium Supplement: Magnesium Glycinate

  • Magnesium glycinate is recommended due to its benefits and properties.
  • Composed of magnesium bound to the amino acid glycine.
  • Benefits of glycine include increased cognitive function and reduced inflammation.

Benefits of Magnesium Glycinate

  1. Prevents Muscle Cramps
  2. Promotes Relaxation
    • Improves sleep quality
  3. Reduces Blood Pressure
    • Acts as a vasodilator
  4. Regulates Calcium Levels
    • Reduces kidney stone risk
  5. Improves Insulin Sensitivity
    • Reduces diabetes risk
  6. Reduces Migraine Frequency
  7. Reduces Anxiety and Stress
    • Lowers cortisol levels

Advantages of Magnesium Glycinate

  • Easiest magnesium form on the stomach - ideal for those with sensitivities.
  • High bioavailability means more magnesium is utilized by the body.
    • Example: If a supplement is 50% bioavailable, only 50 mg of 100 mg is used by the body.
  • Can be taken with or without food, regardless of pH levels.

Dosage Recommendations

  • Start with 100 mg, increase by 100 mg if necessary (e.g., 200 mg, 300 mg, etc.).
  • Best taken before bed to enhance sleep quality.

Considerations and Side Effects

  • Low side effect profile, but high doses can cause stomach issues (nausea, cramping, diarrhea).
  • Long-term high doses may lead to low blood pressure.
  • Can interfere with certain prescription medications, especially antibiotics.
    • Consult with a doctor if planning to take high doses (400-800 mg/day).

Recommendations for Enhanced Absorption

  • Combine with Vitamin B6 and Vitamin D3 to increase absorption.

Conclusion

  • Magnesium glycinate is highly recommended for its benefits and minimal side effects.
  • Always consult with a healthcare professional before starting a new supplement regimen.
