B vitamins and especially vitamin B6 are most commonly associated with enhancing metabolism. There are also many others that can aid in increasing metabolism such as vitamin C, and Green Tea.

Some substances have limited evidence to suggest they actually increase metabolism. Vitamin C has been shown to increase fat-burning, but only amongst overweight individuals who were Vitamin C deficient.

Omega 3 fatty acids are essential. this means that the body needs them but cannot produce them by itself.
Scurvy is easily cured by increasing the intake of vitamin C, either by supplement or eating citrus fruits such as lemons, limes and oranges.
