These Foods/Herbs Enhance the Function of Testosterone

 
Grains

Oats are claimed to stimulate the release of Testosterone from its “bound” state (with Sex Hormone Binding Globulin (SHBG)) to its “free” state.  

Herbs

  • Fenugreek Seeds may increase Testosterone levels (Steroid Saponins in Fenugreek Seeds stimulate the release of Luteinizing Hormone which in turn stimulates the production of Testosterone). 
  • Horny Goat Weed is claimed to increase Testosterone levels. 
  • Korean Ginseng increases the body’s endogenous production of Testosterone.  research
  • Maca is claimed to increase Testosterone levels. 
  • Nettle inhibits the binding of Testosterone to Sex Hormone Binding Globulin (SHBG), resulting in lower levels of “bound” Testosterone and higher levels of “free” Testosterone (this occurs from Nettle binding to SHBG in place of Testosterone). 
  • Saw Palmetto inhibits the conversion of Testosterone to Dihydrotestosterone (DHT).
  • Tribulus terrestris is speculated to enhance the conversion of Androstenedione to Testosterone (although Androstenedione is the immediate precursor of Testosterone, it is speculated that this conversion occurs under the influence of Luteinizing Hormone (which Tribulus terrestris is claimed to increase production of)):  Some studies have claimed that daily intake of 750 mg of Tribulus terrestris results in an increase in free Testosterone levels of 30%

Legumes

  • Velvet Beans increase Testosterone levels.


Vegetables

  • Garlic increases Testosterone levels (due to the Diallyl Disulfide content of Garlic increasing Luteinizing Hormone (LH) levels. 


Diet

  • Persons using the Anabolic Burst Cycling method (of dieting) have exhibited significant increases in Testosterone levels.


Sleep

  • Testosterone production and release occurs during Sleep and Sleep deprivation leads to lower serum levels of Testosterone. 


These Substances Interfere with Testosterone

  • Alkaloids
  • Caffeine decreases free Testosterone levels (in postmenopausal women).
  • Enzymes
    Aromatase catalyzes the conversion of Testosterone to Estradiol (although some conversion of Testosterone to Estradiol is beneficial, excessive conversion of Testosterone to Estradiol is undesirable).
    Testosterone is converted to Dihydrotestosterone (DHT) by the 5-Alpha Reductase enzyme:
  • Hormones
    Elevated Cortisol levels inhibit the production of Testosterone.
    Supplemental Melatonin inhibits the production of Testosterone - although low dosage levels of Melatonin (up to 3 mg per day) do not appear to interfere with Testosterone production. 
  • Lipids
    Trans-Fatty Acids decrease Testosterone levels
  • Pharmaceutical Drugs
    Aspirin interferes with the body's production of Testosterone. 
    Cimetidine decreases circulating levels of “free” Testosterone and decreases the biological effectiveness of Testosterone (via a presently unknown mechanism).
    Some types of Major Tranquilizers (e.g. Phenothiazines such as Chlorpromazine) cause depletion of the body's Testosterone reserves (by rapidly metabolizing Testosterone). 
  • Recreational Drugs
    Alcohol (ethanol) decreases the production of Testosterone and lowers the body’s Testosterone levels. 
    Cocaine lowers serum Testosterone levels. 
    Marijuana reduces serum Testosterone levels. 
    Tobacco smoking inhibits the production of Testosterone (by causing the destruction of Leydig Cells that normally produce Testosterone). 

These Foods Interfere with Testosterone

Vegetables
Vegetarians have approximately 18% lower Testosterone levels compared to meat eaters (this occurs because vegetarians have a lower intake of Dietary Fats which are precursors for Testosterone production; also the Fiber Polysaccharides in Vegetables bind to Testosterone and other Steroid Hormones). 


These Ailments Interfere with Testosterone

  • Aging Process


Testosterone production declines in tandem with the Aging Process. 

Age    % of Free Testosterone Compared to Free Testosteroneat Age 18

18    100%
40:    80%
50:    60%
 

Nervous System

  • Excessive Stress reduces the body's levels of Testosterone. 
  • Physical Therapies
    Excessive Exercise (i.e. overtraining) suppresses the body's Testosterone production: 
    Endurance Exercise reduces (both bound and free) Testosterone levels.
    Excessive Isotonic Exercise (i.e. overtraining) can cause (temporary) depletion of endogenous Testosterone during the 24 - 48 hour recovery period between workouts in people who engage in Isotonic Exercise.
