Vanadium:
Vanadium is required for glucose tolerance. It aids in glucose oxidation
and transport. The University of Vancouver, BC, Canada stated the

be linked to cardiovascular and kidney disease.
Vanillin:
A natural tanning accelerator that reacts with skin proteins under
the influence of heat and light to produce a tan. A white crystalline
aldehyde having a burning taste and characteristic odor of vanilla.
It is extracted from vanilla pods, and is also obtained by the decomposition

vanillin is used widely either as a sweetener or as a flavor exhauster,

all types of fruit and tutti-frutti flavors, root-beer, cream-soda
etc. Vanillin itself has some bacteriostatic properties and has,

Vitamin A: (Beta Carotene) Helps maintain
smooth, soft disease-free skin; helps protect the mucous membranes
of the mouth, nose, throat lungs, which helps reduce our susceptibility
to infections; protects against air pollutants and contaminants;
helps improve eye sight and counteracts night-blindness; aids in
bone and teeth formation; improves skin elasticity, moisture content
and suppleness; and helps reverse the signs of photo-aging. A lack
of vitamin A can cause skin to become dry and hardened. Go to the
Vitamins Dictionary and look up Vitamin A.
Vitamin A derivatives (Retinoids: retinol,
retinyl palmitate, retinyl linoleate, retinyl acetate) Vitamin A

and body regulators that work better together than alone.
Vitamin B1: See Thiamine.

for healthy teeth, gums Bones; helps heal wounds, scar tissue, Fractures;
prevents scurvy; builds resistance to infection; aids in the prevention

of calcium and phosphorus, and for preventing rickets. It is fat-soluble
and is not sensitive to heat, light, or oxygen.
Vitamin E: Vitamin E is a major anti-oxidant
nutrient; retards cellular aging due to oxidation; supplies oxygen
to the blood which is then carried to the heart and other organs;
