When you get tested, your doctor will see if you require supplementation. I try and have clients maintain a serum blood level between 50 and 80 ng/mL. Studies have shown that men with lower levels of vitamin D had lower levels of testosterone. If a man tests below my preferred range, I typically recommend 5,000 IUs a day until the levels improve. Vitamin D3 supplements are widely available (best is to get one that contains vitamin K as well, as that allows for greater absorption), and you can also bump up your sunlight exposure. I find, and studies confirm this, that many men are deficient in vitamin D and it is a huge issue relating to testosterone levels.
Before the ready availability of non-injectible testosterone preparations, and because of their ease of administration by the oral route, 17-alkylated steroids were popular surrogate agents for testosterone. These substances, however, were capable of inducing several risk factors for coronary artery disease (Kopera 1993; Hall and Hall 2005) and as a consequence, particularly after the revelations of extensive 17-alkylated anabolic steroid abuse by athletes, testosterone, became unjustly incriminated. The evidence, however, tends to suggest just the opposite; testosterone may even be cardioprotective. Dunajska and colleagues have demonstrated that when compared to controls, men with coronary artery disease tend to have: lower total testosterone levels and free androgen indices, more abdominal fat, higher blood sugar and insulin levels (Dunajska et al 2004).
The normal development of the prostate gland is dependent on the action of testosterone via the androgen receptor, and abnormal biosynthesis of the hormone or inactivating mutations of the androgen receptor are associated with a rudimentary prostate gland. Testosterone also requires conversion to dihydrotestosterone in the prostate gland for full activity. In view of this link between testosterone and prostate development, it is important to consider the impact that testosterone replacement may have on the prevalence and morbidity associated with benign prostatic hypertrophy (BPH) and prostate cancer, which are the common conditions related to pathological growth of the prostate gland.
Magnesium deficiency is another widespread problem in our country. While this makes you prone to stress and muscle cramps, it also starves your body’s endocrine system of a vital mineral it needs for testosterone production. We wrote another article on how magnesium alone can send your testosterone levels through the roof. You have to check it out.
ZMA (unnecessary). So when I researched how to increase testosterone, a supplement called ZMA kept popping up. It’s a blend of zinc, magnesium, and vitamin B6. The purported benefits of ZMA include better and deeper sleep which indirectly is supposed to increase testosterone. Zinc and magnesium are necessary minerals in testosterone production, so a mega-dose should be useful, right? Well, no. I bought some and took it during the duration of experiment. I should have done some more research before I made the purchase. While one study in 1998 showed increased strength among athletes taking ZMA, two recent studies (study 1, study 2) have shown that it has absolutely no effect on total or free testosterone levels. Crap. My advice, unless you have a zinc and magnesium deficiency, no need to waste your money on this.
Take 250 mg of Forskolin, standardized to 10 percent, twice a day. Take one serving before training and the other with a meal. According to "Natural Anabolics," Forskolin decreased body fat and increased free testosterone levels in training individuals as compared to a placebo. Forskolin comes from the herb coleus forskohlii and is also known as Forslean.
Ashwagandha is sometimes included in testosterone supplements because of the hypothesis that it improves fertility. However, we couldn’t find sufficient evidence to support this claim (at best, one study found that ashwagandha might improve cardiorespiratory endurance). WebMD advocates caution when taking this herb, as it may interact with immunosuppressants, sedative medications, and thyroid hormone medications.
Heavy metal, fluoride, chlorine, pesticides, dioxins and other dangerous chemicals that are in our food, products and even the air we breath are wreaking absolute havoc on our endocrine systems (responsible for testosterone production). It’s hard to avoid these (especially if you’re a smoker) but they are major contributors to man’s decline in testosterone.
It doesn’t get more natural than getting a good night’s sleep. Research published in the Journal of the American Medical Association showed that lack of sleep can greatly reduce a healthy young man’s testosterone levels. That effect is clear after only one week of reduced sleep. Testosterone levels were particularly low between 2 and 10 p.m. on sleep-restricted days. Study participants also reported a decreased sense of wellbeing as their blood testosterone levels dropped.
The brain is also affected by this sexual differentiation;[13] the enzyme aromatase converts testosterone into estradiol that is responsible for masculinization of the brain in male mice. In humans, masculinization of the fetal brain appears, by observation of gender preference in patients with congenital diseases of androgen formation or androgen receptor function, to be associated with functional androgen receptors.[95]
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.
The unsexy truth is that increasing T naturally simply comes down to making some long-term changes in your diet and lifestyle. As you’ll see, what I did to increase T largely boils down to eating better, exercising smarter, and getting more sleep. That’s pretty much it. But as with most things in life, the devil is in the details, so I’ll share with you exactly what I did and provide research that explains why the things I did helped boost my testosterone.
On the average, you need to sleep at least 8 hours per night to stay healthy. If you want a night sleep to contribute to the maximum testosterone production, it’s important to make your sleep comfortable. Thus, the bedroom temperature shouldn’t exceed 21°C. In addition, you should ventilate your bedroom thoroughly before sleeping. Furthermore, before going to bed, don’t overload your stomach with fatty foods, as well as don’t drink alcohol and caffeinated beverages. Finally, you have to avoid intense physical activity before bedtime.6

Japanese Knotweed (a.k.a Hu Zhang or Polygonum cuspidatum) is highlighted by WebMD as needing more evidence to rate its effectiveness in a number of different areas: like treating constipation and liver or heart disease. They also warn that it can interact poorly with medications that are changed and broken down by the liver, and those that slow blood clotting (anticoagulants and antiplatelets).
Magnesium deficiency is another widespread problem in our country.

Stick to protocols that stress large degrees of muscle mass and are moderate- to high-intensity. Additionally, more seasoned gym-goers may want to incorporate forced repetitions periodically into their programs, as testosterone increases have been observed with this type of training.14 Incorporating other post-failure training techniques such as dropsets or partials may similarly be associated with higher T production.

There is also solid research indicating that if you take astaxanthin in combination with saw palmetto, you may experience significant synergistic benefits. A 2009 study published in the Journal of the International Society of Sports Nutrition found that an optimal dose of saw palmetto and astaxanthin decreased both DHT and estrogen while simultaneously increasing testosterone.6 Also, in order to block the synthesis of excess estrogen (estradiol) from testosterone there are excellent foods and plant extracts that may help to block the enzyme known as aromatase which is responsible producing estrogen. Some of these include white button mushrooms, grape seed extract and nettles.7
The final two studies looked directly at soy vs testosterone levels. The first looked at introducing consumption of soya flour on testosterone levels. They found that those who ate the Soy flour lowered their T levels during the study (43). And the second study looked at the consumption of soy protein isolates (powder) in healthy men. They found that testosterone levels decreased upon consumption of soy powder (45).
When you're under a lot of stress, your body releases high levels of the stress hormone cortisol. This hormone actually blocks the effects of testosterone,6 presumably because, from a biological standpoint, testosterone-associated behaviors (mating, competing, aggression) may have lowered your chances of survival in an emergency (hence, the "fight or flight" response is dominant, courtesy of cortisol).
There are several supplements on the market claiming to be natural testosterone boosters. I get these sorts of things in the mail all time. The companies that produce these products claim that the herbs (typically stinging nettle and tribulus) in their pills increase free testosterone by reducing SHBG. They also throw in some B vitamins for “increased energy and vitality.”
For people who are worried about low or high testosterone, a doctor may perform a blood test to measure the amount of the hormone in the patient's blood. When doctors find low-T, they may prescribe testosterone therapy, in which the patient takes an artificial version of the hormone. This is available in the following forms: a gel to be applied to the upper arms, shoulders or abdomen daily; a skin patch put on the body or scrotum twice a day; a solution applied to the armpit; injections every two or three weeks; a patch put on the gums twice a day; or implants that last four to six months.

It's an old secret of the adolescents of Kerala (Land of Coconuts), India, that if you want to grow mustache and beard faster, then you have to consume more coconuts. They didn't know however that it was due to the ability of coconuts to increase testosterone. Coconut is mainly saturated fats which are considered to be the best type of fat for increased testosterone production.
When we face stress, our adrenal glands secrete cortisol to prepare our bodies and minds to handle the stressful situation — the primal fight-or-flight response. In small dosages, cortisol is fine and even useful, but elevated cortisol levels for prolonged periods can do some serious damage to our bodies and minds. One area that seems to take a hit when cortisol is high is our testosterone levels. Several studies have shown a link between cortisol and testosterone. When cortisol levels are high, testosterone levels are low; and when testosterone levels are high, cortisol levels are low.

Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than testosterone, so that its androgenic potency is about 5 times that of T.[114] The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.
Prolactin is suppressed by dopamine activity. Since supplementing L-DOPA suppresses prolactin (by increasing dopamine activity), supplementing L-DOPA would increase testosterone if prolactin was abnormally high. The average, healthy male does not have elevated prolactin (unless he’s on steroids), so supplementing with L-DOPA will not increase your testosterone levels.
Dr. Anthony’s Notes: Vitamin D has about 100 other beneficial body functions outside of it's impact on testosterone. Make sure you take the active Vitamin D3 (not D2 – from plant sources!) It’s also advisable to get 20 minutes of sunshine daily (weather permitting) – without sunscreen. Verdict: this is one of the natural testosterone supplements that work. Best Food Sources of Vitamin D3: Wild Alaskan Salmon (#1), Sardines, Eggs How To Take Vitamin D3: Using 3000-5000IU of Vitamin D3 per day is a good safe, research supported dose. Your physician can also test your blood for D3 levels for more precise monitoring.
Vitamin D, a steroid hormone, is essential for the healthy development of the nucleus of the sperm cell, and helps maintain semen quality and sperm count. Vitamin D also increases levels of testosterone, which may boost libido. In one study, overweight men who were given vitamin D supplements had a significant increase in testosterone levels after one year.5
Your diet is the best source of zinc; along with protein-rich foods like meats and fish, other good dietary sources of zinc include raw milk, raw cheese, beans, and yogurt or kefir made from raw milk. It can be difficult to obtain enough dietary zinc if you're a vegetarian, and also for meat-eaters as well, largely because of conventional farming methods that rely heavily on chemical fertilizers and pesticides. These chemicals deplete the soil of nutrients ... nutrients like zinc that must be absorbed by plants in order to be passed on to you.
There are the testosterone deficiency signs, such as loss of sexual desire, erectile dysfunction, impaired fertility, chronic fatigue, etc. But it’s not always possible to understand which medical condition caused the decrease in testosterone levels. For example, if you always feel exhausted and have no sexual desire, it may provide evidence of depression.
Vitamin D supplementation may potentially boost testosterone levels, but further research is needed to determine if it really has an effect on the testosterone levels of young people and athletes. The truth is likely similar to zinc and magnesium — being in a deficient state causes your testosterone levels to drop below baseline, and supplementing it just takes you right back to baseline (but not any higher).
Your first step should be to see your doctor. If you think you have low testosterone, we cannot stress enough that you should proceed with caution and talk to a medical professional — taking a booster can definitely do more harm than good. Low testosterone can be a symptom of more serious problems, like a pituitary disorder or a side-effect of medication, and a booster can mask the root cause. A doctor will be able to evaluate your testosterone levels with a simple blood test, and if you both decide a booster is the way to go, give the ingredients of any supplement a once-over to make sure that they’re not at risk of making your personal health situation worse.
This supplement contains herbal remedies to enhance the male hormone and increase a man's sexual desire. Ingredients found in the product include horney goat weed, milk thistle, tribulis terristris, wild yam, saw palmetto and maca. The manufacturer of the supplement claims that it is endorsed by a doctor for male enhancement. Recommended dosage is one capsule taken before engaging in sexual activity. Women should not take a testosterone supplement unless otherwise advised by a physician.
“Before taking Andro400, my husband weighed 290 lbs. He's a diabetic and his blood pressure was through the roof. I purchased Andro based on the reviews, and he's lost 60 - 70 lbs! ​It's enhanced him health-wise in a lot of aspects too. He used to be depressed because of his weight. The fact that he was losing weight like crazy gave him a lot of relief. He's not depressed now, he's really happy. He's more loving. And it's so exciting for me as a wife to see him happier -- it made me happier​! ​ So I'm really grateful. Andro400 gave him a lot of ​energy ​ too because of the testosterone boost.​ The 3 main things everybody's noticing are: no more​ depression, a lot more energy and ​the huge weight loss. He went from size 42 to 38, so it's like, oh my God it's WORKING!! Trust me, we've tried a lot of other things that didn't work. And that's why I'm so excited because it's actually, literally changing our lives!”

As crazy as it seems, it has lately been proven that there is a no relation between cholesterol intake and heart attack as doctors once thought (and many still do). This is slowly becoming common knowledge, regardless of pharmaceutical companies wishes. (Trust me, this billion dollar industry does not want you to know this. You don;t have to be a conspiracy theorist to see this.)

Popular through the centuries in Ayurvedic healing (a traditional practice of medicine in India) ashwagandha is what is known as an "adaptogen." This means the body may be able to use it to help adapt to stressors. While many people supplement with it for reducing cortisol, anxiety, and fatigue levels, ashwagandha also holds relevance for us here with potential testosterone boosting benefits.[8]

A recent study conducted on trained subjects showed that squats stimulated a greater testosterone response than leg presses.10 Stick with multijoint exercises like squats, bench presses, and deadlifts—the kinds of compound lifts that'll help jack up your testosterone levels. Since machines isolate a muscle you're working (less stabilizer activity), they're not as good a choice compared to free weights.

I bought most of the ingredients for my Testosterone Salad at Whole Foods. For those curious, I added up all the ingredients and divided by six (I typically ate six of these salads in a week). The cost per salad was roughly $5. That’s about the price many folks pay every day for a crappy fast food meal. If you’re on a budget, I’m sure you could get the ingredients at Walmart and bring the cost per salad down even more.


We should probably start with the elephant in the room: do these supplements increase testosterone? The answer is probably yes. There are some ingredients that help convince your body to produce more testosterone, but there’s a catch. Testosterone boosters aren’t actually great at boosting; that is, at pushing your testosterone levels above your healthy, normal balance. Boosters typically act more like restorers — helping bring low testosterone levels back to that healthy equilibrium rather than boosting you above normal testosterone levels. Just like how if you have anemia, taking a vitamin B12 supplement can help restore your energy and reduce fatigue, but if your B12 levels are good, a supplement won’t give you super energy levels to stay awake for three days — your body will likely just process (read: pee) out the extra.
Looking for ingredients that work in the realm of supplements can be like finding a needle in a haystack. Testosterone boosters, like all dietary supplements, are not approved by the Food and Drug Administration prior to marketing. This lack of oversight dates back to the 1994 Dietary Supplement Health and Education Act (DSHEA), which stipulated that purveyors of supplements weren’t required to prove the safety of their products or the veracity of what’s on the labels to the FDA before listing them for sale. Often, there isn’t a lot of scientific backing behind an ingredient, or research has been done solely on animals, not humans.
Tribulus terrestris is an ingredient commonly presented as improving testosterone levels, but has not been found to be more effective than a placebo or possess any testosterone increasing properties. WebMD cautions that it interferes with Lithium and diabetes medications, and in general, not enough is known about tribulus terrestris to recommend a dosage for anyone.
The first of the natural testosterone boosters is intermittent fasting. One of the biggest intermittent fasting benefits? It’s been shown to increase testosterone by nearly 200 percent or even up to 400 percent. (4) In addition, a study by the University of Virginia Medical School noted that growth hormone levels increased 2,000 percent over the baseline in men who ate no calories for 24 hours, and growth hormone levels are correlated with testosterone. (5)
Sergeant Steel ran into trouble here because it contains Shilajit — a type of plant-based resin. Shilajit is banned in Canada because the Canadian government found heavy metal levels when investigating the ingredient. Shilajit is hard to find, and sensitive to water and variations in temperature, so most manufacturers mix it with additives to make it more stable. Research at Boston University School of Medicine found that “nearly 21 percent of 193 ayurvedic herbal supplements [...] contained lead, mercury or arsenic,” and included shilajit on the list of contaminated ingredients. Even though Sergeant Steel lists its shilajit is “purified,” it doesn’t offer any third-party testing to confirm whether or not their shilajit contains heavy metals, and so we cut it.

Testosterone is nothing short of a must-need supermundane hormone for men. If you are suffering from any deficit or even complete lack of any of the attributes mentioned above, then you are probably in short of proper testosterone or has the menacing amount of estrogen. Estrogen is the female sex hormone. Just like how a few amounts of testosterone is formed in women, men are also vulnerable to host some estrogen. Estrogen could cause the most undesirable things for men. Therefore its count should be checked. Nevertheless, an increase in testosterone will hinder the effects of estrogen and its supply.

Christopher Walker is a co-founder of UMZU and creator of the Thermo Diet. He is the first person to get a Duke Neuroscience degree in 3 years. After naturally solving his own health complications with a brain tumor as a teenager, he has devoted his life to creating all-natural products and education to help men, women, children and pets to improve their own health naturally using science-backed research.
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.
Lose some weight – It goes without saying that being overweight is unhealthy for more than one reason. As your weight increases, your testosterone levels decrease inevitably. The good news is that as soon as you start losing weight, you can reverse this process and your testosterone levels will begin rising again. Could you think of a better reason to exercise regularly?
Why do we need magnesium? Magnesium is an essential nutrient in the body that can help decrease the risk of developing osteoporosis, improve insulin sensitivity, and lower the risk of hypertension. This article looks at other health benefits of magnesium, what happens if a person has a deficiency, supplements, and how to include it in the diet. Read now
Consume organic dairy products, like high-quality cheeses and whey protein, to boost your branch chain amino acids (BCAA). According to research, BCAAs were found to raise testosterone levels, particularly when taken with strength training.12 While there are supplements that provide BCAAs, I believe that leucine, found in dairy products, carries the highest concentrations of this beneficial amino acid.
