Tongkat Ali (Eurycoma longifolia)

Tongkat Ali is a traditional Southeast Asian herb that has been studied for its potential to support healthy testosterone levels, stress management, and male fertility. Research suggests it may help with mood regulation and energy levels, though most studies are small and short-term. Dietary supplements are not FDA-approved to diagnose, treat, cure, or prevent any disease. Consult your doctor before starting any supplement.

Key Takeaways

  • Tongkat Ali may help support healthy testosterone levels and stress management, with most research showing benefits at 200-400mg daily of standardized extract
  • Clinical studies suggest potential improvements in mood, energy, and male fertility, though research is still limited and primarily involves short-term studies
  • The supplement works by potentially supporting the body's natural hormone production rather than directly supplying hormones
  • Quality varies significantly between products due to extraction methods and potential contamination with heavy metals or adulterants
  • Benefits may take 4-12 weeks to become apparent, making it more suitable for long-term rather than immediate use

How to Take

Typical Dosage

200-400mg daily of standardized extract, based on clinical research. Most studies used 200mg daily for up to 8 weeks. Higher-quality standardized extracts may require lower doses.

When to Take

Can be taken with or without food. Some users prefer taking in the morning to avoid potential sleep disruption.

Why It Matters for Ages 50+

Men over 50 often experience natural declines in testosterone levels, and Tongkat Ali has been studied for supporting healthy hormone balance in this age group. Additionally, the stress-management properties may be beneficial for adults dealing with age-related life changes and health concerns. However, this demographic is also more likely to take multiple medications, making careful medical supervision essential.

What to Look For

  • Look for standardized water extract (like Physta or LJ100) rather than raw root powder for better bioavailability and consistency
  • Choose products with third-party testing certificates for purity, potency, and heavy metal contamination
  • Verify the extract ratio (typically 100:1 or 200:1) and eurycomanone content, which should be clearly labeled
  • Select products stored in dark, sealed containers and check expiration dates as potency can degrade over time
  • Avoid products making unrealistic claims or those that don't clearly identify the extraction method used

Potential Interactions

Be aware of these potential interactions:

  • Diabetes medications (metformin, glipizide, miglitol): May enhance blood sugar-lowering effects, requiring monitoring
  • Beta-blockers (propranolol): May decrease bioavailability of the blood pressure medication
  • Immunosuppressants (leflunomide): May interact with immune system effects - avoid combination
  • Hormone medications: May interact with treatments affecting testosterone or estrogen levels
  • Blood pressure medications: Potential interactions due to cardiovascular effects - monitor closely
  • Consult your pharmacist if you take any prescription medications, as interactions are not fully documented

Who Should Avoid This Supplement

  • Individuals with hormone-sensitive conditions such as prostate cancer, breast cancer, or other hormone-dependent cancers
  • People with liver disease or elevated liver enzymes, as isolated cases of liver injury have been reported
  • Those with autoimmune conditions or taking immunosuppressive medications due to potential immune system effects
  • Pregnant and breastfeeding women, as safety data is insufficient for these populations
