The form“Why Riboflavin — not Magnesium Glycinate or Magnesium Citrate?”Evidence Strong evidence

Riboflavin is the strongest evidence signal for this outcome.

  • RiboflavinThe pick

    Strong evidence · 400 mg

    Water-soluble vitamin B2 central to energy metabolism and antioxidant recycling; high doses around 400 mg/day are well established for migraine prevention.

  • Magnesium Glycinate

    Strong evidence · 500 mg

    Magnesium chelated to glycine (the bisglycinate chelate); well-absorbed and gentle on digestion, a popular form for relaxation and sleep support.

  • Magnesium Citrate

    Moderate evidence · 450 mg

    Well-absorbed magnesium bound to citric acid; more bioavailable than oxide but mildly laxative at higher doses — the common workhorse for general repletion.
