How does Tongkat Ali work?

Tongkat Ali work through several mechanisms through hormonal activation via the endocrine system. The primary endocrine system controls the release of hormones such as testosterone, testosterone, norepinephrine, progresterone, estrogen, Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), Growth Hormone (GH), renin and angiotensin, cortisol and dopamine via Pituitary Glands and Adrenal Glands.

Here is how Tongkat Ali work and the science behind it.

  1. Tongkat Ali contains ingredients such as eurycomanone,  a family of quassinoids and alkaloids that work by activating hormone-inducing actions in our body.
  2. Tongkat Ali activates Luteinzing Hormones (LH) that stimulates the Leydig cells in your testicles to produce testosterone. In women, the Luteinizing Hormones (LH) triggers the creation of steroid hormones from the ovaries and that helps with menstrual cycle and ovulation.
  3. Tongkat Ali decreases the sex hormone binding globulin (SHBG) which in turn, delivers higher production of testosterone. SHBG rises when your testosterone level is low.
  4. At the same time, Tongkat Ali reduces cortisol, the stress hormone that lowers the testosterone in our body.
  5. The mechanism of actions collaboratively increase production of “free testosterone” in our body.
  6. Therefore, increased free testosterone from Tongkat Ali provides more energy, improved mood, improved sexual libido, more sperm motility, stronger muscle growth, reduced body fat, increased immune system and reduction of stress.

How long does it take for Tongkat Ali to take effect?

Depending on your age and health conditions, past scientific studies showed that Tongkat Ali will take into effect between several hours to several days. However, in most cases, you can feel the difference in energy levels after 12 to 24 hours.

Despite initial findings, it had attracted more research specialists to investigate whether Tongkat Ali can improve erectile dysfunction.

A study published in the Journal of Evidence-Based Complementary and Alternative Medicine showed improvement in erection hardness and time, sperm motility and concentration amongst others.

Tests on daily consumption of 300mg of Tongkat Ali on 26 test subjects (with Placebo group) aged 40-64 years of age showed sufficient evidence that Tongkat Ali can be used safely as a natural viagra.

Tongkat Ali offers a wide range of scientifically-proven benefits beyond its single-use as natural viagra.

What is the highest testosterone increase from consuming Tongkat Ali?

The highest testosterone increase that was ever recorded in a clinical trial was in 2019 using Physta Tongkat Ali extract on a randomized placebo-controlled group of 93 participants (both male and female) between 20 – 60 years.

Test results showed a jump in free testosterone of 582% in men and 600% in women after 24 weeks.

What is the long term impact of taking Tongkat Ali?

Long-term consumption (i.e six months) of Tongkat Ali conducted by a group of scientists at the University of Santarina Brazil in 2020, showed a significant increase in testosterone amongst middle-aged men after consuming 200mg of Tongkat Ali daily with 3-day exercise per week.

There are no reported cases of side effects from long-term consumption of Tongkat Ali. A person taking Tongkat Ali for six weeks (42 days) reported more stamina, better sleep, weight loss, and an increase in muscle mass.

What is the recommended Tongkat Ali dosage?

Typical dosage recommendations are between 50 mg to 100 mg a day, and 100 mg to 200 mg if you are seeking noticeable improvement in sexual function, healthy aging and sports performance. Most clinical trials and studies were conducted using a daily intake of 200 mg – 400mg daily for a prolonged period between 4 to 12 weeks. 

What is the toxicity limit of Tongkat Ali?

The toxicity limit (defined as the Lethal Dose 50, or LD50) of Tongkat Ali was observed to be 3,000 mg / kg of body weight which is based the acute toxicity study using on a water-based Tongkat Ali extract. Therefore, the Human Equivalent Dose (HED)toxicity limit for Tongkat Ali is therefore estimated to be 14,500 mg / kg. The LD50 of 5,000mg – 15,000mg/kg is classified as “practically non-toxic” based on toxicity classification of food and pharmaceutical ingredients.

What is the maximum limit and how much Tongkat Ali can I take per day?

Most of the studies and clinical trials on various health benefits were based on daily consumption of 200mg to 400mg Tongkat Ali daily and this is regarded as safe. The maximum limit is approximately 1,000mg to 1,500mg in a single dose.

However, if you are an active sportsperson that works out daily, participating in competitive sports or an amateur athlete, higher consumption of Tongkat Ali (eg: 600mg) is recommended to gain better performance output.
