Tongkat Ali

Tongkat Ali contains a clinically trialed and standardized root extract of the revered Southeast Asian herb, Eurycoma longifolia, also called ‘Malaysian ginseng’ or ‘Long Jack’. This specific Tongkat Ali extract has been studied extensively in clinical trials.

Long used throughout Southeast Asian countries as a traditional tonic to promote healthy sexual interest and vitality, Tongkat Ali uses are also now supported by scientific evidence. Many of the benefits of Tongkat Ali are thought to be due to its positive effects on testosterone synthesis and free testosterone levels.*

How Tongkat Ali Supports Men’s Health*

The amount of testosterone in a man’s body naturally decreases with age. Levels tend to peak between the age of 25 and 30, but then decline gradually over time. At age 60, testosterone levels may have fallen by more than 50% with everyday stress, diet, exercise and sleep also affecting normal levels. Testosterone levels strongly determine levels of sexual interest, mental and physical energy, and general well-being.^1,2

A special, standardized proprietary root extract of Tongkat Ali has been investigated in a number of research studies in men of Asian and American descent aged 40 years and over.³ These studies clearly demonstrate beneficial effects in various areas of men’s health that include sexual interest,^3-5 healthy testosterone levels,^1,3,6,7 free testosterone levels,^1,3,6,8,9 overall well-being and vitality.^1,3,4,7,10*

Benefits of Tongkat Ali

Tongkat Ali is designed for men wanting to maintain normal levels of sexual interest. It may benefit men experiencing a normal age-related decline in testosterone levels and those looking to support normal healthy blood levels of free testosterone. Older men wanting to maintain their normal vitality levels and general wellbeing may consider Tongkat Ali.*
