In a recent study (4), a randomized direct comparison was made between parenteral and oral supplementation in CE dogs
Common additions in a B12 IV drip include: Vitamin C for immune support and antioxidant protection
If you dont supplement, an elevated B12 can be a marker for underlying conditions including liver disease, kidney dysfunction, or certain blood disorders
However, its common for blood tests to reveal inaccurate information regarding B12 levels since a high percentage is stored in the liver and not always revealed through testing (for example, taking large amounts of folic acid has been found to mask vitamin B12 deficiency in some patients)
The entire process takes mere minutes during an office visit
However, they need to make sure the supplement provides acceptable amounts of vitamin B12 made from high-quality ingredients
