Menadione Sodium Bisulfite: The Synthetic Vitamin K to Avoid

Not all vitamins are created equal. Learn why Menadione is a controversial additive linked to liver toxicity.

A "Vitamin" you actually want to avoid.

The Reveal: Menadione (often listed as Menadione Sodium Bisulfite Complex) is a synthetic version of Vitamin K. It is significantly cheaper than natural Vitamin K sources. However, it has been linked to liver toxicity and damage to cell membranes. Many "premium" brands still sneak this into their vitamin premix.

The Standard: Look for Vitamin K from natural sources like Kale, Spinach, or Alfalfa.
