What are the benefits of Tongkat Ali and Fadogia Agrestis?

Tongkat Ali and Fadogia Agrestis are popular supplements, whether they are stacked or consumed separately. The benefits of Tongkat Ali and Fadogia Agrestis include:

  • Improved Libido.
  • Stress reduction.
  • Improved Immune System.
  • Improved Athletic Performance.

Improved Libido.

Various scientific studies have linked the consumption of both Tongkat Ali and Fadogia Agrestis to improved libido. There are many potential reasons for this. Firstly, both supplements can boost free testosterone levels in men and women, which can result in an increased sex drive.

One study published in the Journal of the International Society of Sports Nutrition

found that Tongkat Ali consumption can help “individuals adapt to the reduced energy, mood, and libido that often comes with age,” linking this to a reduction in cortisol (the stress hormone) and improved energy levels.

A study in Pharmacognosy Review noted similar results relating to the consumption of Fadogia Agrestis, noting that it increases the concentration of testosterone within the bloodstream of male rats.

Stress reduction.

Tongkat Ali and Fadogia Agrestis supplements are also used by those looking to better their mental health – especially when it comes to stress and anxiety.

For example, studies suggest that both supplements are useful when it comes to lowering cortisol levels within the body. As cortisol is the hormone that is primarily responsible for mediating the body’s stress response, consuming Tongkat Ali and Fadogia Agrestis could be particularly beneficial for those routinely dealing with high levels of stress and anxiety.

Some studies suggest that the supplements can also increase the consumer’s production of dopamine, otherwise known as the “happiness” hormone, to a similar effect.

Improved Immune System Function.

Each year, more and more studies are conducted into both Tongkat Ali and Fadogia Agrestis as their usage within the global healthcare industry becomes more widespread. Recent developments have found that both supplements could also help to improve immune system function.

For example, Tongkat Ali contains compounds such as Quassinoids, which have anti-viral and anti-inflammatory properties, which can help strengthen an individual’s immune system and fight off or prevent infection.

Improved Athletic Performance.

While they are typically favored for their aphrodisiac qualities, Tongkat Ali and Fadogia Agrestis are also linked to improved athletic performance. They can also help with muscle growth and development. This could likely be attributed to the fact that they reduce fatigue quite considerably, making it easier for individuals to find their stride when working out.

What are the potential side effects of Tongkat Ali and Fadogia Agrestis?

As with any supplement, there are potential side effects that users may encounter when taking Tongkat Ali or Fadogia Agrestis.

However, the majority of consumers do not experience any negative side effects, especially when they consume the recommended dosage of each supplement. If you are concerned, speak with your healthcare provider before incorporating either supplement into your diet or routine.

However, as their benefits often overlap, many people are unsure which supplement they should take or which is better.

Unfortunately, there have been no specific studies that outline the benefits (or potential side-effects) of each supplement side-by-side in order to draw a concrete conclusion. This means it often comes down to personal preference.

However, there are some occasions on which you may prefer to take one supplement over the other. For example, if you are taking specific medications, you should check ahead of time to ensure that the supplements will not interfere with this.

Furthermore, many people find supplement stacking and taking both Tongkat Ali and Fadogia Agrestis at the same time to be useful. After all, this means that they are able to enjoy the benefits of both supplements, often allowing for more immediate results, especially when it comes to athleticism.

Either way, whether you are taking the supplements together or separately, it is important that you purchase these products from a trusted retailer or manufacturer. You should also ensure that you follow the recommended dosage. Those with specific healthcare issues should contact their physician or healthcare provider ahead of time to ensure that they’re able to take Tongkat Ali and Fadogia Agrestis without issue.

Tongkat Ali and Fadogia Agrestis are available in the form of capsules, liquids (teas), and powders. There are currently no studies to suggest one method of consumption is better than the other, as they serve the same core purpose. As such, this often comes down to personal preference.
