Yohimbe Extract
Also known as: Yohimbe, Johimbe, Yohimbine
Overview
Yohimbine is an alkaloid derived from the bark of the *Pausinystalia johimbe* tree, native to West Africa. It is commonly used as a dietary supplement for various purposes, most notably for treating erectile dysfunction and as a potential aid for weight loss. Yohimbine functions primarily as an alpha-2 adrenergic receptor antagonist, which can increase blood flow and enhance sexual function. It is available in various forms, including capsules and tablets, and is often marketed for its potential to improve sexual performance and support weight management. Research on yohimbine is moderate, with several clinical trials and meta-analyses available, providing a solid foundation for understanding its efficacy and safety. However, it should be used with caution and under medical supervision due to potential side effects.
Benefits
Yohimbine has demonstrated effectiveness in treating erectile dysfunction. A meta-analysis showed an odds ratio of 3.85 (95% CI: 2.22 to 6.67) compared to placebo, indicating a significant improvement in sexual function. Some studies suggest potential benefits for weight loss, although the evidence is less robust. It may be particularly beneficial for individuals with erectile dysfunction, including those with diabetes. The onset of benefits for erectile dysfunction is generally observed within a few weeks of consistent use. Overall, the benefits for erectile dysfunction appear to outweigh the risks when used appropriately.
How it works
Yohimbine primarily works by blocking alpha-2 adrenergic receptors in the body. This action increases the levels of norepinephrine, a neurotransmitter that plays a role in various physiological processes, including blood flow and sexual arousal. By blocking these receptors, yohimbine can increase blood flow to the penis, which helps improve erectile function. It primarily affects the cardiovascular and nervous systems, influencing blood pressure and heart rate. Yohimbine's interaction with these systems contributes to its effects on sexual function and potential weight loss.
Side effects
Yohimbine is generally considered safe when used appropriately, but it can cause several side effects. Common side effects (occurring in more than 5% of users) include anxiety, insomnia, and increased heart rate. Less common side effects (1-5%) include nausea and dizziness. Rare side effects (less than 1%) may include severe allergic reactions. Yohimbine may interact with certain medications, such as blood thinners and antidepressants. It is contraindicated in individuals with certain medical conditions, such as high blood pressure or heart disease. Pregnant or breastfeeding women should avoid yohimbine due to a lack of safety data. It's crucial to use yohimbine under medical supervision to monitor for and manage potential adverse effects.
Dosage
The minimum effective dose of yohimbine is typically around 5-10 mg per day. Optimal dosage ranges are 10-20 mg per day for erectile dysfunction. It is generally not recommended to exceed 20 mg per day. Yohimbine is best taken on an empty stomach to enhance absorption. It is available in capsules or tablets. Food intake may affect its absorption. Due to the potential for side effects, it is important to start with a low dose and gradually increase as needed, under the guidance of a healthcare professional.
