B12 Liquid (Methylcobalamin): Quick-Absorbing Energy & Neurological Support*

B12 Liquid by SFI Health provides a high-potency, quick-absorbing dose of the active form of vitamin B12, methylcobalamin. This essential vitamin is crucial for supporting red blood cell function, cardiovascular health, and neurological wellness. The convenient liquid form is designed to be held in the mouth before swallowing, allowing for fast and efficient absorption. It’s an ideal choice for individuals who may have difficulty absorbing B12, including older adults and those with plant-based diets.*

How It Works: Active B12 for Direct, Fast Absorption*

This formula delivers a clinically relevant dose of Vitamin B12 in its superior, active form for immediate use by the body.*

Bioavailable Methylcobalamin
Unlike the more common cyanocobalamin, methylcobalamin is the active coenzyme form of B12. This means the body does not need to convert it, allowing for more efficient and immediate utilization. This form is critical for a variety of metabolic processes, including the synthesis of red blood cells and the maintenance of a healthy nervous system.*

Rapid Liquid Delivery
The liquid format is designed for rapid delivery. By holding the liquid in the mouth for 30 seconds, the B12 can be absorbed directly into the bloodstream through the mucosal membranes, bypassing potential absorption issues in the digestive tract. This makes it a highly effective option for quickly boosting B12 levels.*

  • Provides 1,000 mcg of active methylcobalamin B12 per serving
  • Supports red blood cell function, cardiovascular, and neurological health*
  • A quick-absorbing liquid form for fast and efficient use
