What's the difference between Active and Inactive B Vitamins?

Active, or activated, simply means that each B vitamin is in its bioavailable form.*

It's important to realize that most B vitamin supplements contain the less expensive, inactive form of each B vitamin.

Why does this matter?

Inactive forms must be converted (or "methylated") by the liver in order to become active, bioavailable forms that can be absorbed and utilized by your body.*

But because your liver can only convert them so fast, most inactive B vitamins are quickly eliminated from your body before offering many benefits.*

But that's not the only problem...

  • As you age, your body's ability to convert inactive B vitamins to their active usable form becomes less and less.*
  • Some individuals are pre-disposed and have trouble absorbing B vitamins making it critical to have the active, readily-available form.*
  • Stress, medications, caffeine, sugar, and refined carbohydrates deplete B vitamins, increasing your body's requirement.*
