More T With Tongkat Ali

Here’s why Eurycoma longifolia (aka Tongkat ali) is one of the “alpha” ingredients in both JYM testosterone-optimizing products.

More T With Tongkat Ali

One of the main ingredients in both Alpha JYM and Alpha X is Eurycoma longifolia, more commonly known as Tongkat ali. When it comes to supporting both total and free testosterone levels, this is one ingredient you definitely want in your supplement arsenal.

Here’s what you need to know about Tongkat ali and why I’m such a big fan of it.

The Science Behind Tongkat Ali

Originating from the lush rainforests of Indochina and Indonesia, Eurycoma longifolia is a shrub that's been traditionally used for its medicinal properties. Recent scientific scrutiny has revealed its potential as a natural testosterone enhancer. The mechanism behind its effects is fascinating: It stimulates the Leydig cells in the testes, which are responsible for converting cholesterol into testosterone, thus ramping up testosterone production. Additionally, it seems to thwart the conversion of testosterone into estrogen, which not only elevates testosterone levels but also lowers estrogen levels.

A comprehensive review and meta-analysis of studies involving healthy men, both those with low and normal levels of testosterone, has provided compelling evidence of Tongkat ali's efficacy. The findings suggest that Eurycoma longifolia can significantly and safely promote higher testosterone levels in men across the board.

The Evidence Speaks

When we look at the research on this ingredient, the numbers speak volumes. Healthy men with already normal testosterone levels experienced an approximate 15% increase in their testosterone after supplementing with Tongkat ali in doses ranging from 100 to 600 milligrams per day. Even more impressive, men grappling with low testosterone levels saw about a 50% surge in their levels after taking 200 milligrams per day.

The Takeaway on Tongkat Ali

For anyone looking to elevate their testosterone — whether you're aiming to enhance your performance, bolster your fitness gains, or address low testosterone levels — Tongkat ali presents a promising natural solution. It's noteworthy that, despite its testosterone benefits, Tongkat ali does not skew the urinary testosterone-to-epitestosterone ratio, a critical factor in sports doping analysis. This makes it a safe option for competitive athletes subject to drug testing.

How to Incorporate Tongkat Ali into Your Regimen

If you're considering giving Tongkat ali a try, I recommend a daily intake of 100 to 300 milligrams, split into two servings at different times of day. To make it easy, you can just get it through Alpha X or Alpha JYM; Alpha X provides 300 mg of Eurycoma longifolia, and Alpha JYM 100 mg.

As men continuously seek natural methods to enhance our health and performance, Tongkat ali stands out as a valuable supplement. Its ability to naturally and safely support testosterone levels is a potential game-changer for many.
