Synephrine is a naturally occurring alkaloid found in certain plants, particularly in the peel of bitter oranges (Citrus aurantium). It belongs to a class of compounds known as protoalkaloids. The substance is chemically similar to ephedrine, another alkaloid found in some plants, but it has a slightly different structure.

Here is some information about the origin, nature, and introduction of synephrine:


Synephrine is primarily found in the peel of bitter oranges. Bitter oranges are a type of citrus fruit that is native to Southeast Asia but is now cultivated in various parts of the world.

Synephrine gained attention in the context of dietary supplements and weight loss products. It is often included in formulations marketed as thermogenic or fat-burning supplements.

These products claim to boost metabolism and promote weight loss. Synephrine is believed to have thermogenic properties, meaning it may increase the body’s heat production and energy expenditure.

Use and Controversies:

Synephrine has been used as an alternative to ephedrine in dietary supplements, especially after ephedrine-containing products were banned or restricted in some regions due to safety concerns.

However, the safety and efficacy of synephrine-containing supplements have also been a subject of debate and scrutiny. Some studies suggest potential risks, particularly when combined with other stimulants.

Regulatory Status:

The regulatory status of synephrine-containing supplements varies across countries. In some places, there are regulations in place to monitor and control the use of these compounds in dietary supplements.

It’s important to note that while synephrine occurs naturally in bitter oranges, its concentrated form in supplements may have different effects, and caution is advised when considering its use, especially in combination with other substances. As with any supplement, individuals should consult with healthcare professionals before incorporating it into their regimen, especially those with pre-existing health conditions.
