You just watched Dr. Barron break it down.
Many of those signs trace back to one thing your body may be low on: B12.
If low B12 is behind them, a methylcobalamin injection is a direct, absorbable way to replenish it. Here is how to get one, prescribed by Dr. Barron through Yuvia.

B12 is a vitamin your body uses for energy metabolism, nerve health and healthy red blood cells. It gets harder to absorb from food with age. Every Yuvia vial is prescribed by a board-certified specialist and compounded at a licensed US pharmacy.
Methylcobalamin, the active form of B12, in a full 50mg (50,000mcg) 10mL vial, compounded at a licensed US pharmacy. Compounded medications are not FDA-approved.
Swallowed B12 has to survive digestion before it reaches your bloodstream, and absorption drops with age. An injection goes in directly, using a small syringe just under the skin. Everything you need ships with the vial.
