What We Like

  • NSF Certified for Sport: Suitable for tested athletes
  • Flexible dosing: Pipette allows finer adjustments than tablets
  • High purity: Free from gluten, soy, and dairy
  • Good bioavailability: Methylcobalamin is the active form, ready to use

What We’re Missing

  • Price: Significantly more expensive than lozenge formats
  • Light-sensitive: Requires refrigeration or dark storage to maintain stability

Usage Recommendation

1 ml (approx. 20 drops) daily under the tongue, hold for 30 seconds. Take with breakfast if stomach sensitivity is a concern.
