Which Is Better Tongkat Ali or Ashwagandha?

You should take Ashwagandha if you want to reduce anxiety or lower your blood sugar levels. But you should take Tongkat Ali if you want to reduce stress or improve fertility.

What is Ashwagandha?

ashwagandha plant

Ashwagandha (Withania Sommnifera) is a herb native to India that’s been used for many health conditions for over 4,000 years. It’s a member of the Solanaceae family of plants which includes popular vegetables like potatoes and eggplants.

It’s known for its ability to promote feelings of calmness, wellbeing, and strength in people.

In the Sanskrit language, Ashwagandha loosely translates to the smell of a horse, suggesting it can give you the strength of a stallion.

(Ashwagandha root allegedly smells like horse sweat. A fair trade-off for giving you the strength of a stallion in my view!)

What is Tongkat Ali?


Tongkat Ali (Eurycoma Longifolia) is a shrubby tree native to Indonesia, Malaysia, and Southeast Asia.

Seen as a national treasure in Malaysia, Tongkat Ali has been used for its health promoting properties for many centuries.

Like Ashwagandha, it works as an adaptogen meaning it helps your body adapt to stress.


Benefits of Ashwagandha

Ashwagandha may help lower blood sugar levels

High blood sugar levels can give you an energy crash, leading to fatigue, mood swings, and brain fog.

This low energy state will steal your will power, meaning you’re more likely to gorge on sugary foods which will restart this cycle.

(This is how you become addicted to junk food.)

But not to worry – recent research shows that Ashwagandha may help lower blood sugar levels.

For example, a study of 12 subjects looked at how Ashwagandha powder changed their blood sugar levels.

After using Ashwagandha for a month, their blood sugar levels were lowered by amounts comparable to a blood sugar lowering drug.

Ashwagandha may help increase muscle size and strength

Although Ashwagandha is rarely discussed in the weightlifting community, research shows it’s useful for those wanting to get bigger and stronger.

A study of 57 people investigated the effects of Ashwagandha on muscle size and strength.

Each day of the study, some participants took 600mg of Ashwagandha and the others took a placebo.

The results showed that the Ashwagandha users had bigger increases in muscle size, strength, fat loss, and testosterone levels than the others.

Ashwagandha may help increase testosterone levels

Lots of people have lower than ideal T levels nowadays.

There are a few reasons for this including low-fat diets, poor sleep hygiene, and lower meat consumption.

But low T levels are nothing to scoff at – they may even contribute to depression in aging men. (Source)

And this is where Ashwagandha proves to be useful.

A study of 75 infertile males found that Ashwagandha supplementation increased Seminal testosterone levels.

Ashwagandha may help relieve anxiety

Here’s a shocking fact for you.

Over 40 million US adults suffer from anxiety disorders.

This makes anxiety the most common mental illness in America.

Well according to research, Ashwagandha may be effective at relieving anxiety.

In one study, the subjects took either 600mg of daily Ashwagandha or a placebo for 2 months.

The results showed that the Ashwagandha group had a bigger reduction in scores on the stress test than the placebo group.

Another study compared the anxiety levels of subjects taking either Ashwagandha or a placebo each day for 6 weeks.

By the end of the study, 88% of the Ashwagandha takers had less anxiety.

Benefits of Tongkat Ali

Tongkat Ali may help reduce stress

Research suggests that Tongkat Ali may be useful for those under stress.

In one study, 63 people under stress took either 200mg of daily Tongkat Ali or a placebo for 4 weeks.

By the end of the study, the Tongkat Ali takers reported less stress, anger, and tension.

They also had lower levels of cortisol in their saliva.

(Cortisol is often referred to as the stress hormone.)

Tongkat Ali may help increase T levels

Like Ashwagandha, Tongkat Ali may help boost your T levels.

In one study, 76 subjects with low T levels took 200mg of daily Tongkat Ali for a month.

The results showed that 90% of the subjects had healthy testosterone levels after taking Tongkat Ali.

Tongkat Ali may help boost male fertility

According to research, Tongkat Ali may help improve male fertility.

For example in one study, 109 subjects took either 300mg of daily Tongkat Ali or a placebo for 12 weeks.

The results showed that the Tongkat Ali takers had an 18% increase in seminal fluid volume and a 44% increase in sperm motility.

In another study, 75 sub-fertile males took 200mg of daily Tongkat Ali for 3 months.

According to the results, the Tongkat Ali significantly improve their sperm quality.

Tongkat Ali may help increase muscle size and strength

Like Ashwagndha, Tongkat Ali may help boost muscle gains and strength.

For example in one study, 25 people took 400mg of daily Tongkat Ali for 5 weeks.

According to the results, the subjects had significantly increased strength after taking Tongkat Ali.

In another study, 14 people took either 100mg of daily Tongkat Ali or a placebo for 5 weeks.

The results showed that the Tongkat Ali takers had bigger increases in lean mass than the placebo takers.

  • Sleepiness
  • Headaches
  • Upset stomach

Also, since Ashwagandha can affect your blood sugar levels, those taking medications that affect your blood sugar levels should speak to a doctor before supplementing with Ashwagandha.

The following people should avoid Ashwagandha:

  • Pregnant women
  • People with stomach ulcers
  • People with low/high blood pressure
  • People who are allergic to Solanaceae plants, i.e. Potatoes, Eggplants, etc.

But until further research is done, pregnant/nursing women and children should avoid supplementing with Tongkat Ali.

You can’t go wrong with NaturaLife Labs Ashwagandha.

What I like about it

I love that this Ashwagandha contains only organic, natural ingredients meaning it’s free from any nasty herbicides or pesticides.

Another good feature is the addition of black pepper extract.


Well, it’s believed that Ashwagandha is more bioavailable when taken with black pepper extract, which means your body utilizes it better.

Potential Drawbacks

Assuming you follow the recommended serving size and take it every day, a bottle will only last a month or so which is a bit of a pain.
