Tongkat Ali

Studies commonly use 200 to 400 mg per day of a standardized water extract (often standardized to eurycomanone). Many products advertise a 100-to-1 or 200-to-1 extract ratio, but look for standardization rather than just a high ratio, and stick to the labeled dose.

Tongkat ali (Eurycoma longifolia) is most popular for supporting healthy testosterone, energy, libido, and exercise performance, and it is also studied for stress and cortisol balance. It is traditionally a Malaysian tonic herb.

Most people take it in the morning, with or without food. Because long-term safety data is limited, many users cycle it, for example a few weeks on with a break, or five days on and two off. Give it a few weeks to assess.

It is generally well tolerated at labeled doses; reported effects are mild, such as restlessness or trouble sleeping if taken late. Quality matters, since some imported products have been found contaminated with heavy metals, so choose tested brands. Check with your doctor if you have a hormone-sensitive condition.
