If you’re a frequent reader here in AM, you already know that increased dietary fat intake is directly correlated with increased testosterone production. And not only that, but the types of fat that increase T seem to be saturated fats (SFAs) and monounsaturated fats (MUFAs), while polyunsaturated (PUFAs) actually tend to lower testosterone (more here).
Now you know I prefer studies conducted on human participants instead of rodents, but often there is no choice.  A Japanese study on rats that you can read here: http://jn.nutrition.org/content/131/8/2150.short has demonstrated pretty convincingly that garlic supplementation significantly increases testosterone.  I wish there were more tests on humans but it turns out garlic isn’t patentable (sorry Monsanto) which means there isn’t enough financial interest to warrant human studies.  Maybe I’ll conduct one.  Any volunteers?

Hypogonadism (as well as age-related low testosterone) is diagnosed with blood tests that measure the level of testosterone in the body. The Endocrine Society recommends testing for suspected low T with a total testosterone test. It may be performed in the morning when testosterone levels tend to be highest in young men, although this isn't necessarily the case in older men. The test may be repeated on another day if the results show a low T level. (5)


Testosterone is included in the World Health Organization's list of essential medicines, which are the most important medications needed in a basic health system.[107] It is available as a generic medication.[10] The price depends on the form of testosterone used.[108] It can be administered as a cream or transdermal patch that is applied to the skin, by injection into a muscle, as a tablet that is placed in the cheek, or by ingestion.[10]
Both men and women with Alzheimer’s Disease were found to have an increased concentration of SHBG and decreased free androgen index when compared with controls (Paoletti et al 2004). In a prospective study of 574 men whose baseline age span was 32–87 years and who were followed for a mean of 19.1 years (range, 4–37), the risk of developing Alzheimers’ Disease decreased 26 percent for each 10 unit increase in free testosterone index. The authors concluded that testosterone may be important for the prevention and treatment of AD (Moffat et al 2004).

These results have been echoed in clinical trials. A meta-analysis of 24 RCTs looked at weight loss caused by diet or bariatric surgery:[22] In the diet studies, the average 9.8% weight loss was linked to a testosterone increase of 2.9 nmol/L (84 ng/dL). In the bariatric-surgery studies, the average 32% weight loss was linked to a testosterone increase of 8.7 nmol/L (251 ng/dL).
The hormone also plays a role in sex drive, sperm production, fat distribution, red cell production, and maintenance of muscle strength and mass, according to the Mayo Clinic. For these reasons, testosterone is associated with overall health and well-being in men. One 2008 study published in the journal Frontiers of Hormone Research even linked testosterone to the prevention of osteoporosis in men.
Many endocrinologists are sounding the alarm about the damaging effects that come with exposure to common household chemicals. Called “endocrine disruptors,” these chemicals interfere with our body’s hormone system and cause problems like weight gain and learning disabilities. One type of endocrine disruptor is particularly bad news for our testosterone levels.
Finally, we looked at the proprietary blends of our remaining boosters, and dug into their ingredient lists. Supplements frequently include ingredients known for their “folk-lore” value; they’re believed to work, even when there isn’t any scientific background to prove it. Though we didn’t ding points if an ingredient wasn’t proven to be good (just so long as it wasn’t proven to be bad), we didn’t want to include any ingredient with evidence of causing harm.

We reviewed the ingredient lists of our supplements and cut three that prescribed us an overdose of magnesium. While it’s possible to stay under the 350mg daily limit of supplemental magnesium by taking fewer pills than the manufacturer recommends, we were concerned that any manufacturer would advise you to exceed the recommended safety limit for magnesium intake by almost a third.
4. Foods rich in vitamin A. Vitamin A is more commonly known for its association with eyesight improvement, but it is also a vitamin supplements the production of testosterone. The June 2004 issue of the Clinical Endocrinology journal published research conducted by Israel’s Kaplan Medical Center. This study involved Israeli boys that had delays in puberty. These boys were given Vitamin A supplements and foods rich in Vitamin A over the course of 6 months, and most of them showed an improvement with their testosterone levels. If you want to boost the level of testosterone in your body, food types that are rich in Vitamin A are carrots, sweet potatoes, squash, cantaloupe and eggs.

“This study establishes testosterone levels at which various physiological functions start to become impaired, which may help provide a rationale for determining which men should be treated with testosterone supplements,” Finkelstein says. “But the biggest surprise was that some of the symptoms routinely attributed to testosterone deficiency are actually partially or almost exclusively caused by the decline in estrogens that is an inseparable result of lower testosterone levels.”

Testosterone is a steroid from the androstane class containing a keto and hydroxyl groups at the three and seventeen positions respectively. It is biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites.[5] It exerts its action through binding to and activation of the androgen receptor.[5] In humans and most other vertebrates, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. On average, in adult males, levels of testosterone are about 7 to 8 times as great as in adult females.[6] As the metabolism of testosterone in males is more pronounced, the daily production is about 20 times greater in men.[7][8] Females are also more sensitive to the hormone.[9]


A 2010 study published in the journal Hormones and Behavior first suggested this when researchers evaluated the “dual-hormone hypothesis” clinically. (11) They discovered that when cortisol is elevated, testosterone responds by elevating as well but soon after bottoms out at a much lower level than before cortisol kicked in! That means you want to find ways to relieve stress to keep your testosterone levels up.
Why bother with such common micronutrients? Because it's not uncommon for athletes to suffer from zinc and magnesium deficiencies, partly due to inadequate replenishing of levels after intense bouts of exercise. Deficiencies in these key minerals can lead to a poor anabolic hormone profile, impaired immune function, and increased cortisol, ultimately leading to decreases in strength and performance.[6]
In males, the testosterone test can help find the reason for sexual problems, like reduced sex drive or erectile dysfunction. If you’re having a hard time getting your partner pregnant, the test can tell if your blood testosterone level is low. It can also screen for problems with the hypothalamus or pituitary gland. This controls how much testosterone your body makes.

Testosterone is necessary for normal sperm development. It activates genes in Sertoli cells, which promote differentiation of spermatogonia. It regulates acute HPA (hypothalamic–pituitary–adrenal axis) response under dominance challenge.[22] Androgen including testosterone enhances muscle growth. Testosterone also regulates the population of thromboxane A2 receptors on megakaryocytes and platelets and hence platelet aggregation in humans.[23][24]
Zinc deficiency also negatively affects testosterone levels, according a 2014 article in the Journal of Plant Biochemistry and Physiology. The authors of this review note that zinc supplementation can increase circulating testosterone in some populations. In fact, daily supplementation with typical doses may double testosterone within a few months.
Does zinc provide testosterone benefits? The answer is, yes. It is an essential mineral which is used in many processes within the body and has a similar role like vitamin D. Men who have a deficiency of zinc may suffer from low testosterone levels but taking zinc supplements can help them to improve the testosterone levels. Zinc deficiency is an essential factor in infertility because it also reduces the sperm count, but with supplements, the sperm count increases along with improvement in testosterone levels. It also helps to recover from high-intensity interval training because that also cause the decline in testosterone levels.
Cognitive abilities differ between males and females and these differences are present from childhood. In broad terms, girls have stronger verbal skills than boys who tend to have stronger skills related to spatial ability (Linn and Petersen 1985). It is thought that the actions of sex hormones have a role in these differences. Reviewing different cognitive strengths of male versus female humans is not within the scope of this article but the idea that cognition could be altered by testosterone deserves attention.
‘Testosterone boosting’ products  - found online, or in health food or body-building shops, these products claim to boost testosterone levels if you buy them. The majority of these products will not have the effect you want and are not worth spending money on. Any of these products that do have a real effect may have a form of prescription medication in which is both dangerous and illegal.

Beast Sports Nutrition - Super Test has all four of our dream ingredients: magnesium, fenugreek, longjack, and zinc. These ingredients have all been demonstrated to help increase natural testosterone levels, with plenty of scientific research to support them (done on humans too, and not just rats). By combining all four ingredients, Super Test has the best chance of helping to increase your testosterone levels, and thereby helping you gain muscle or have a more active sex life.
Few examples: In this 2014 study, a bunch of researchers tested multiple different diets with added Lactobacillus Reuteri on male rodents. In every single case, the addition of L.Reuterii to the feed increased testosterone levels, increased luteinizing hormone levels, increased testicular size & weight, prevented age-related testicular shrinkage, improved semen parameters, and even increased markers of social domination.
Testosterone is a sex hormone that plays important roles in the body. In men, it’s thought to regulate sex drive (libido), bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm. A small amount of circulating testosterone is converted to estradiol, a form of estrogen. As men age, they often make less testosterone, and so they produce less estradiol as well. Thus, changes often attributed to testosterone deficiency might be partly or entirely due to the accompanying decline in estradiol.
