18 Aug Tongkat Ali (Eurycoma longifolia) Benefits, Dosage & Reviews
Tongkat Ali is a herbal supplement with alleged stimulant and testosterone-boosting effects. Men use it to enhance sexual health and performance, and some evidence backs them up. Historical research is also investigating the effects of the plant on osteoporosis, diabetes, and anxiety. Read more below to learn about the science behind Tongkat Ali, such as dosage, testimonials, and side effects.
What is Tongkat Ali?
Eurycoma longifolia, commonly called Tongkat Ali, long jack, or Malaysian ginseng, is a plant found in the Malaysian rainforest.
Men use it for erectile function and for enhancing libido, sexual performance, fertility, fertility, making it the nickname”Malaysia’s home-grown Viagra”.
Researchers are also investigating whether this plant influences:
- Bone formation
- Muscle strength and athletic performance
- Physical and mental energy levels and quality of life
- Anxiety and pressure
- Bacteria and yeast
- Antioxidant defense
- Blood sugar
However, clinical trials are lean. Only a couple of Tongkat Ali’s uses are supported by strong evidence.
Furthermore, Tongkat Ali supplements have not been accepted by the FDA for clinical usage. Supplements generally lack strong clinical study. Regulations set manufacturing standards for them but don’t guarantee that they’re effective or safe. Speak with your physician before supplementing.
Another serious concern is that some Tongkat Ali supplements out of Malaysia are found to contain toxic metals, drugs, or unknown plant chemicals. In case you choose to supplement, take careful steps to acquire a high-quality, pure herbal extract.
The stem and root extracts of Eurycoma longifolia contain:
- Quassinoids (e.g., eurycomaoside, eurycomanone, pasakbumin-B): The antiparasitic, and antiulcer effects of these chemicals are still an area of study.
- Alkaloids, the antibacterial qualities of that are being researched.
Mechanism of Action
The mechanism of action of Tongat Ali in humans is unknown. Scientists consider this plant could increase testosterone levels by stimulating the production of testosterone from pregnenolone and 17-OH-pregnenolone. Others hypothesize it blocks aromatase, the enzyme which converts testosterone to estrogen. These mechanisms remain unproven.
Possible Health Benefits of Tongkat Ali
Possibly Effective for:
1) Infertility in Men
Some clinical evidence suggests that Tongkat Ali may the grade of sperm in infertile men.
In a single 12-week analysis (DB-RCT) of 109 men (ages 30 to 55), Tongkat Ali increased sperm motility and semen volume compared to placebo.
In another 9-month study of 75 men with infertility, Tongkat Ali supplements improved semen volume, sperm concentration, sperm motility, and sperm quality, thus improving infertility.
Scientists think that Tongkat Ali might operate by reversing the inhibitory effects of estrogen on testosterone manufacturing, based on animal research. This mechanism hasn’t yet been confirmed in humans.
2) Sexual Desire
According to a trial, Tongkat Ali may increase sexual appetite in men that are healthy.
In a 12-week study (DB-RCT) of 109 men, Tongkat Ali increased libido and improved erectile function compared to placebo.
In another 12-week study (DB-RCT) of 26 men, a specific freeze-dried water extract of Tongkat Ali (Physta) enhanced sexual performance and increased the hardness and duration of erections.
Tongkat Ali additionally increased libido, sexual stimulation, and performance in healthy, impotent, castrated, and old male rats, and middle-aged mice.
Possibly Ineffective for:
Some clinical data suggest that Tongat Ali does not enhance physical performance in athletes.
In 1 trial of recreational male athletes, Tongat Ali (150 mg daily) 7 days earlier and one hour before endurance running did not enhance performance. In another trial of healthy men, a particular brand of Tongat Ali extract (Physta) 300 mg per day for 12 weeks did not improve physical fitness, compared to placebo.
Insufficient Evidence for:
The subsequent purported benefits are only supported by limited, low-quality clinical studies.
There is inadequate evidence to support the use of Tongkat Ali for some of the below-listed uses.
Remember to speak with a doctor prior to taking Tongkat Ali nutritional supplements. Tongkat Ali should never be used as a replacement for accepted medical therapies.
There is inadequate evidence to indicate that Tongkat Ali increases testosterone levels, though early studies show some promise.
A 5-week pilot study of 25 seniors found that Tongkat Ali improved testosterone levels and muscle strength in both men and women. Tongkat Ali supplementation also increased testosterone levels in a 4-week study of 76 men with hypogonadism (an impaired function of the testes).
Testosterone blood levels are used to track men with low testosterone levels. Urinary testosterone is mainly used in forensics to appraise testosterone doping.
At a 15-week analysis (DB-RCT) of 13 amateur athletes, Tongkat Ali did not increase testosterone levels in the urine. Based on these findings, the authors concluded that supplementation should not breach the International Olympic Committee’s doping policies.
There is insufficient evidence to rate the effectiveness of Tongkat Ali for enhancing muscle strength.
Tongkat Ali supplements increased muscle strength in both women and men in a 5-week pilot study of 25 seniors.
In the same way, at a 5-week pilot study of 14 healthy guys, Tongkat Ali increased muscle size and strength and improved athletic performance.
Large-scale studies are necessary.
Tension and Stress
Insufficient evidence exists to determine the effects of Tongkat Ali on tension and anxiety.
4-week research on 63 moderately stressed individuals showed that Tongkat Ali root extract reduced stress hormone (cortisol) amounts, tension, anger, and confusion.
Tongkat Ali also reduced the frequency of battling episodes and increased exploratory behavior in mice, which leads to anxiety in animals. We can’t extrapolate these findings to humans and appropriate clinical trials are lacking.
Immune System Response
There is insufficient evidence concerning the effects of Tongkat Ali on the immune system.
Within a 4-week study (DB-RCT) of 83 areas, Tongkat Ali supplements improved T cells, CD4+ T cells, and naïve T cell amounts, which enhanced overall immune function.
Insufficient evidence is to ascertain whether Tongkat Ali impacts weight loss. Suitable, large scale clinical trials are needed.
In a single 12-week study of 109 healthy men, Tongkat Ali reduced fat mass, waist circumference, and hip size compared to placebo. But, weight loss wasn’t the primary focus of this study.
In another (pilot) study of 14 healthy, Tongkat Ali supplements increased muscle strength and size while reducing body fat after 5 weeks. No conclusions could be drawn from the research, because it lacked a placebo group and also contained such a small sample. Some additional studies have replicated its findings.
Some scientists are also investigating whether Tongkat Ali influences body weight and belly fat in mice, but research is still in the early stages.
Lacking Evidence (Animal Research)
No clinical evidence supports the use of Tongkat Ali for any of the conditions listed in this part.
Below is a summary of the present creature and cell-based research, which should guide additional investigational efforts. On the other hand, the research listed below should not be interpreted as encouraging of any health benefit.
In cell culture, researchers are investigating whether Tongkat Ali activates the creation of bone-building proteins (such as BMP-2, RUNX-2, and OCN) that increase bone formation.
One research group indicated that Tongkat Ali prevents calcium reduction in the bones of castrated male rats . However, in a different study, Tongkat Ali failed to restore testosterone levels and bone mass in the castrated rats with osteoporosis. Far more studies are needed.
Researchers are looking at how Tongkat Ali can affect These parasites and bacteria in the lab:
- Salmonella, E. coli, staph, and typhoid-causing bacteria).
- Blastocystis sp, a parasite that causes intestinal problems.
- Toxoplasma gondii, a parasite causing toxoplasmosis.
They guess its quassinoids may have microbe-fighting properties.
However, the effects of Tongkat Ali on infections in humans are unknown.
Other Areas of Research
Other aspects of Tongkat Ali mobile and animal research include its potential effects on:
- Blood sugar management
- Blood pressure
- Antioxidant (free radical scavenging) defense
- Alcohol-induced stomach injuries
These effects remain unexplored in people.
Last, Tongkat Ali is said to reduce fever, but there are no clinical or animal studies to support this.
Supplementing with Tongkat Ali
Safety & Toxin Contamination Concerns
Cosmetic Tongkat Ali nutritional supplements are possibly safe when used in the appropriate dosage for as much as 9 months.
But you should be extremely cautious when buying Tongkat Ali supplements.
Some supplements from Malaysia are found to contain toxic metals like mercury, cadmium, and lead.
Some were also adulterated with sildenafil (Viagra). Others don’t contain Tongkat Ali whatsoever but loosely-related species. Adulteration with certain poisonous chemicals can be fatal.
Make sure you buy supplements just from trusted manufacturers and do not hesitate to require an excellent certification.
Studies suggest Tongkat Ali can cause:
Tongkat Ali herbal java was correlated with higher blood pressure in pregnant women and fetal discomfort.
Pregnant and breastfeeding women should avoid Tongkat Ali due to a lack of security data.
Supplement-drug interactions can be dangerous and, in rare cases, even life-threatening. Always ask your doctor before supplementing and let them know about all drugs and supplements you are using or considering.
Tongkat Ali may decrease the absorption of beta-blockers (such as propranolol).
Tongkat Ali inhibits the metabolic actions of CYP1A2, CYP2A6, and CYP2C19 enzymes. These enzymes are a part of the CYP540 family, that are responsible for breaking down or triggering drugs. Inhibition of these enzymes may create interactions with particular drugs (e.g., some antidepressants, beta-blockers, statins, warfarin, and antiepileptics).
Forms of Supplementation
Tongkat Ali is an herbal supplement available in the form of pills, water-soluble powder, and coffee.
Most clinical trials used 200mg to 400mg of a Malaysian Tongkat Ali water extract daily.
