Benefits

What B12 does for your body

A few of the well-documented effects of optimizing your B12 levels.

Boost energy

B12 powers cellular energy production — more output without caffeine or other stimulants.

Improve circulation

B12 is essential for red blood cell production. A deficiency can lead to fatigue and anemia.

Detoxify liver

B12 supports liver function — filtering toxins and regulating fat-soluble vitamins.

Better sleep

B12 helps produce melatonin, which regulates sleep cycles and light sensitivity.

Improved mood

A cofactor for neurotransmitters like serotonin and dopamine that regulate mood.

Support metabolism

B12 and legacy-listed lipotropic ingredients support normal energy metabolism.
