Validase Invertase is a dry food grade invertase enzyme preparation (beta-fructofuranosidase) derived from yeast. Validase Invertase catalyzes the hydrolysis of sucrose (cane or beet sugar) into its component parts, D-fructose and D-glucose. Essentially, it is used for the rapid hydrolysis of sucrose to produce invert sugar solutions.

Myoglobin supplies oxygen to muscle cells for use in the chemical reaction that results in muscle contraction. Iron also prevents fatigue and promotes good skin tone.
