Yohimbe is an alkaloid extracted from the Yohimbe tree which supports healthy male sexual function and promotes weight loss.
Yohimbe Mode of Action
Yohimbe is an alkaloid of the Pausinystalia yohimbe tree and in the plants of the Rauwolfia family (1). It is also known as Corynanthe johimbi and Corynanthe yohimbe. The Yohimbe tree is native to central and western Africa, primarily the Congo, Cameroun, and Gabon. It has been used as an aphrodisiac in folklore (2).
The active indole alkaloid is found in the bark of the yohimbe tree. The bark can contain up to 0.6-1.38% of the yohimbe alkaloid, combined with other alkaloids chemicals that account for up to 6% of the content of the bark. Most supplements are standardized to the yohimbe content alone (2).
The aphrodisiac effects of yohimbe are due to the dilation of blood vessels in the genitals, increased reflex in the spinal cord, and the transmission of nerve impulses to genital tissue. The sexual enhancement effects are believed to be through increased blood flow to the genitals and central nervous system excitatory impulses for men. In women, the sexual enhancement effects are believed to be through increasing blood flow to the vagina and its blood vessels (2).
Yohimbine is one of Yohimbe’s constituents which works directly on the central nervous system by increasing sympathetic outflow and increasing the release of norepinephrine. Yohimbine also inhibits monoamine oxidase (MOA), peripheral serotonin receptors, calcium channels, and can deplete dopamine within the brain (2).
Yohimbine also promotes weight loss due to its ability to promote lipid metabolism, and it increases fat burning through inhibiting alpha-2 adrenoceptors on fat cells (2).
Pure Nootropics’ Yohimbe contains 2% bark plant extract (standardized to 2.2% Yohimbine HCL) and provides 5 mg per capsule. Suggested use for adults is 1 capsule by mouth daily.
