Best Natural Testosterone Boosters For Muscle Growth
I'm sure you've noticed those muscular guys in the gym who seem to progress faster than you.
No matter how you hard you train these guys are streets ahead in packing on the muscle. Its as if they just have to look at a barbell and they build muscle.
Of course, it's normal to feel jealous of these guys because you want what they have - the ability to pack on muscle as fast as possible.
So what separates this elite group apart from the rest of the pack?
Its simple, because nine times out of ten, these guys will have a higher than normal testosterone levels.
And its the levels of the male sex hormone that separate the super elite athletes from the rest.
Because testosterone is the hormonal driver for muscle growth, strength, and performance in and out of the bed.
If you're T levels are flagging no amount of training is going to enable you to compete with guy's who have more T flowing through their veins.
Fortunately, there are testosterone boosters that help support the body to maximize optimal T-levels.
These test boosting ingredients are sold either individually or blended into a single product.
What Are Natural Testosterone Boosters
A natural testosterone booster is a safe, legal alternative to the synthetic testosterone commonly used in HRT, bodybuilding, and athletics.
T-Booster supplements contain clinically tested ingredients that stimulate the body to produce healthy levels of free testosterone, which is the most active and anabolic form of the male sex hormone.
Certain test booster pills contain ingredients that increase low T levels in men by blocking or inhibiting estrogen.
Estrogen is the female sex hormone responsible for giving women their feminine characteristics.
In fact, men need small amounts of estrogen to balance out their testosterone.
However, when estrogen increases, testosterone levels drop.
That's a problem because when estrogen levels rise above normal men can develop feminine emotional and physical characteristics.
We're talking man boobs, belly fat, mood swings, emotional swings and much more.
How Do Natural T-Boosters Work?
There's a big difference in the way steroids and natural testosterone hormone boosters affect the body.
Unlike, anabolic steroids natural test boosters support the body to increase natural production of testosterone.
And they do this in 4 specific ways:
- 1Inhibiting Alpha 5 Reductase Enzyme
- 2Inhibits Testosterone Suppressors
- 3Improves Regulation
- 4Optimizes Nutrition
Inhibiting Alpha 5 Reductase Enzyme
Alpha-5-Reductase is an enzyme that converts free testosterone into DHT(Dihydrotestosterone).
By inhibiting the Alpha 5 Reductase enzyme, more active testosterone can be used to build muscle.
On a side note, high levels of DHT are closely linked to enlarged prostate symptoms in older men with low T-levels.
Inhibiting Testosterone Suppressors
Estrogen and cortisol are effective testosterone suppressors, so it's important to keep them under control.
However, environmental pollution, poor diet, sleep deprivation is causing the levels of these testosterone killing hormones to skyrocket.
The impact of high cortisol or estrogen can be seen in men who have difficulty building muscle and losing fat.
A top quality T-booster helps the body achieve a healthy hormonal balance by signaling DNA inside the cells that command the pituitary gland to regulate the release of testosterone more efficiently.
Unfortunately, vitamin and mineral deficiencies can lower testosterone levels.
By feeding your body with T-boosting nutrients, you ensure the testosterone production is fully optimized.
Benefits of Natural Testosterone Enhancement Pills
There's no doubt, anabolic testosterone steroids will increase muscle growth, in the short term.
natural T-boosters have several advantages over synthetic testosterone steroids, especially with your health.
For example, injecting synthetic testosterone shuts down your body's ability to produce natural testosterone.
Over time, the body becomes dependent on synthetic hormones that natural production permanently shuts down altogether.
That's why HRT should only be a last resort because once you're on it, you're on it for life.
And remember, HRT is very expensive.
Its the same with bodybuilders on the juice. After finishing a testosterone steroid cycle, their natural T-levels are severely suppressed.
They need to run a PCT (Post Cycle Therapy) to get their natural T-levels back to normal.
Eventually, long-term steroid use robs the body's own ability to reproduce testosterone.
It's not a problem with natural T Boosters because they assist the body in producing its own.
Best T-Boosting Ingredients To Look For In A Quality Supplement
Several natural ingredients are clinically proven to help increase testosterone levels.
There's also a growing number of natural ingredients with indirect benefit by either blocking or inhibiting the production of estrogen or cortisol.
These natural ingredients help block and inhibit the body's major testosterone suppressors.
When choosing a testosterone boosting supplement make sure it contains at least five ingredients from the following list.
Each year it seems a new T-boosting ingredient is introduced as the best thing to anabolic steroids.
But as you look past the hype you often find no proof or clinical study to support the claims.
Fortunately, we can't lump D-aspartic acid (D-AA) amongst this motley crew of souped-up testosterone boosters.
Most leading male testosterone booster supplements contain D-AA for a good reason.
If you don't already know, D-Aspartic Acid is a non-essential amino acid, which means its produced by the body.
Latest research reveals the amino acid plays a role in enhancing the Luteinizing hormone and the regulation of testosterone production via the pituitary gland (1).
The link between D-AA and the Luteinizing Hormone (LH) is significant because LH is responsible for stimulating the Leydig cells inside the testicles to produce testosterone.
D-AA may help reverse low sperm counts, a worrying trend affecting more men than ever before.
For example, an Italian study revealed that men with low sperm counts saw a significant increase in sperm quality and numbers after taking D-AA supplements over a 2 to 3 month period (2).
The scientists concluded that the positive effects on sperm might have been linked to the D-AA inducing the elevation of testosterone in the testes, which is required for sperm production.
Study 1: Role and molecular mechanism of D-aspartic acid in the release and synthesis of LH and testosterone in humans and rats.
Study 2: D-Aspartate, a Key Element for the Improvement of Sperm Quality Study.
One mineral you don't want to be deficient in is zinc.
Its an essential vitamin with several biological functions.
Zinc is a component of DNA and is necessary for growth, healing, and recovery.
Zinc promotes a healthy nervous system and brain function as well as help the body cope with the effects of stress hormones such as cortisol.
But what about testosterone?
There's also a close link between a zinc deficiency and low T levels in men.
Well, zinc helps the body regulate and control the production of testosterone.
For example, a study (3) by Wayne State University School of Medicine, Michigan, USA, found that restricting the dietary intake of zinc lowered testosterone serum levels.
In contrast, men with zinc deficiencies nearly doubled their testosterone levels after completing a six-month program of zinc supplementation.
In summary, zinc is vital not only for testosterone, but you're overall health and well-being.
A study (3) by Wayne State University School of Medicine, Michigan, USA, found that restricting the dietary intake of zinc lowered testosterone serum levels.
In contrast, men with zinc deficiencies nearly doubled their testosterone levels after completing a six-month program of zinc supplementation.
In summary, zinc is vital not only for testosterone, but you're overall health and well-being.
Oysters contain an abundant amount of zinc.
For example, one average sized oyster can provide 8 to 9 milligrams of zinc, which is nearly the RDA of 11 mg.
Of course, oysters are not to everyone's taste. Personally, I can't eat them raw.
Instead, I chop the oysters and add them to an omelet. Then, a splash of Tabasco sauce on top.
When human skin is exposed to the UVA rays of the sun, the body begins to produce vitamin D. That's why vitamin D is known as the sunshine vitamin.
It turns out; vitamin D3 isn't technically a vitamin.
It's structure is more like a steroid, and it behaves similarly to a hormone as it is synthesized by the body, whereas vitamins are derived from food.
Vitamin D is also one of the most widely studied nutrients, and there are plenty of clinical studies that support its role is promoting healthy testosterone levels.
A deficiency of vitamin D3 is linked with hypogonadism in men (4).
In fact, seasonal patterns have an impact as revealed in this study (5), when testosterone levels dip during the winter months and rise again during the sunnier summer months.
It's easy to become deficient in vitamin D because food sources are limited to mostly fish and shellfish.
And if you live in the northern hemisphere, where there's a lack of sun you're even at a higher risk of vitamin D deficiency.
Boron is a chemical element found in the solar system and the earth's crust. To look at it, you'd think it came from the planet Krypton.
Unlike Kryptonite which is fatal to Superman, boron is known to have a near superhuman effect on men's T-levels.
That may be a slight exaggeration. However, the latest research on Boron is very promising.
For example, in 2011 the University of Medical Sciences in Iran conducted a clinical study (6) investigating the effects of Boron supplementation on testosterone levels and inflammation in the body.
The study involved eight subjects that were given 10mg of Boron per day over a seven day period.
Each of the participant's blood test results revealed a decrease in sex hormone binding globulin (SHBG).
SHBG is a protein that binds to testosterone, making the male hormone inactive. Higher levels of SHBG means less free testosterone is available for the body to use.
What was interesting is the speed in which Boron affected SHBG.
Only eight hours after ingestion SHBG levels decreased and continued to do so throughout and even after the trial finished free testosterone levels increased by 28%.
And that's not, as the participants experienced a significant drop in estrogen.
Magnesium is an essential mineral for strengthening bones, teeth, and promoting healthy lean muscle growth.
And this vital mineral is a co-factor for many enzymes in the body and is necessary for energy production.
But can magnesium increase testosterone?
A number studies (7,8,9) showing magnesium's beneficial effects on T-levels.
You don't need to supplement with magnesium if you've already got adequate levels.
However, if you're like most adults in the US, you're current diet is probably not giving you enough magnesium.
Did you know that you lose a lot of magnesium through sweating?
If you work out regularly or live in a hot environment, your magnesium levels could be below the recommended levels.

Fenugreek is a popular testosterone booster ingredient because of its estrogen blocking properties.
In a randomized controlled trial (10), 30 resistance-trained men were split into a placebo and fenugreek (AI) group.
The AI group were given 500mg of a fenugreek herbal extract containing Grecunin which may inhibit aromatase and 5-a-reductase activity.
The study concluded both groups did experience increases in strength and lean muscle mass due to the resistance training.
However, the AI group saw a 26% increase in bio-available testosterone.
The same dosage of fenugreek extract also had a positive impact (11) on body strength and body composition.
BTW, in India and Asia fenugreek is considered a potent libido enhancer.
There's no real scientific evidence to support this claim apart from this study (12).
However, as India's population is predicted to surpass China as the world's most populated country by 2024, there must be some truth in these claims.

Several top quality test boosters contain Luteolin and for good reason.
Luteolin is a flavone, a type of flavonoid found in the bark and leaves of the Black Myrobalan (Terminalia Chebula) a species of tree native to India and South Asia.
There's no need to fly to India and start chopping down their Black Myrobalan trees because there are foods closer to home that contain Luteolin.
The Following are great examples:
Studies on Luteolin reveal potent antioxidant qualities that help regulate metabolism, treat type II diabetes, strengthen the immune system and even help treat cancer.
However, it is Luteolin's critical aromatase-inhibiting properties that interest us.
It inhibits the aromatase enzyme converting testosterone into estrogen.
As you know, hormones are a balancing act and with less estrogen the more testosterone you're going to have.
Researchers at the University of Minnesota (13) found that Luteolin, among other flavonoids were effective at decreasing aromatase enzyme activity.
And a joint American Chinese study (14) found Luteolin to have estrogen-regulating, anti-inflammatory and cancer fighting properties.
Study 13: Lignans and flavonoids inhibit aromatase enzyme in human preadipocytes.

Study 14: Luteolin, a flavonoid with potentials for cancer prevention and therapy.
Ginseng is another popular ingredient added to many of the leading T-boosters on the market.
And it's easy to see why.
Several clinical studies show ginseng to be an effective libido booster by increasing oxide levels in the blood.
This has the effect of keeping blood vessels soft and supple enabling blood to flow freely.
BTW, Nitric oxide is essential for producing hard erections and testosterone production.
It may be better known as an nitro oxide and erection booster, but more evidence is coming to light that it can enhance testosterone is multiple ways.
Ginseng's ability to help regulate blood sugar levels can be highly beneficial to your testosterone.
For example, Ginseng helps regulate blood glucose levels and this is important because high insulin levels inhibit testosterone production.
Also, high blood glucose is strongly linked to Type II Diabetes.
Interestingly, a clinical study (15), by the University of Rome, La Sapienza Italy, discovered the steroidal saponins found in Panax Ginseng caused an increase in the levels of sperm production and free testosterone.
Furthermore, luteinizing hormone and follicle-stimulating hormone (FSH) levels increased.
BTW, low levels of FSH could indicate problems with the pituitary gland.
Getting the optimal amount of vitamins from your diet is essential for overall health and well-being.
However, there's only a handful of vitamins that directly affect testosterone, and vitamin B6 is one of them.
Its essential functions are:
As you can see, vitamin B6 has a direct effect on hormone regulation and production.
B6 is an essential vitamin, meaning the body doesn't produce it. Instead, we rely on food to get it.
Our body's are not good at storing vitamin B6, so it's vital to replenish it regularly.
As these studies (16) show a B6 deficiency may lower testosterone levels.
In this study (17), vitamin B6 is shown to help reduce estrogen conversion by as much as 30%.
Furthermore, B vitamins regulate tryptophan a vital amino acid for inducing sleep.
This is essential because the body produces and replenishes testosterone while you're asleep.
That's why better quality sleep can mean higher testosterone levels.

Even though helps increase bone strength and reduce the risk of coronary heart disease, most people haven't heard of vitamin K2.
What's more surprising is that vitamin K2 is found in many common foods such as egg yolks, butter, cheese, and liver.
The Western diet contains more K1 than K2.
There are different forms of Vitamin K, but K1 and K2 are the best known.
The Western diet is more abundant in K1 than K2 however, once consumed the body converts K1 into K2.
You may be thinking, "Whats the point in supplementing K2 when our bodies are doing the job for us".
And you would be right but, the conversion seems to be more effective in animals than in humans.
In fact, a study (18) by the Erasmus Medical Center Rotterdam in The Netherlands(1) suggests we should be consuming more K2 in our diets.
But what about vitamin K's effect on testosterone?
Two interesting studies show vitamin K2 has a direct effect on boosting testosterone levels.
The Japanese study (19) by Tohoku University, Sendai, Japan, fed rats a diet enriched with vitamin K2 (Menaquinone-4) over a five-week period.
Testosterone levels in the rat's testes and blood were monitored throughout the five weeks.
The results revealed VK2 supplementation caused a whopping increase in plasma testosterone levels by 70% and an even more significant increase of 90% increase in T-levels within the rat's testes.
What's surprising is that Luteinizing Hormone (LH) levels hardly moved at all, which could suggest K2 is increasing testosterone production inside the testes rather than the brain.
They must love K2 in Japan because, another Japanese study (20) , found a strong association between VK2 and testosterone levels.
Scientists discovered that a VK2 deficiency in rats resulted in much lower testosterone levels compared to rats with no deficiency.
The studies conclusion stated vitamin K2 disrupted the genes involved in the process of converting cholesterol to testosterone.
Although current research is reliant on animal-based studies, the findings do prove a strong link between vitamin K2 and healthy testosterone levels.

Mucana Pruriens is a legume or bean that grows in the tropical forests of Asia and Africa.
The West is only beginning to discover the tropical beans health benefits. However, the East has understood and applied this knowledge for centuries through Ayurveda medicine.
Recent clinical trials on the benefits Mucana Pruriens have caught the attention from many within the scientific community.
So far, Mucana Pruriens scientifically proven properties include:
It's easy to dismiss Mucana Pruriens as a souped-up miracle herb.
However, a growing stack of scientific evidence supports these claims.
Mucana Pruriens biggest draw is its high levels of L-DOPO an amino acid that is a direct precursor to dopamine.
Now, dopamine is a neurotransmitter that's linked to the brain's pleasure and reward receptors and closely associated with sexual arousal.
Furthermore, dopamine is known to help the body boost testosterone by inhibiting prolactin.
Prolactin is a hormone produced by the pituitary gland and is responsible for promoting female milk production.
Men also have prolactin and its released after having sex to counter the effects of dopamine.
Interestingly, after sex most men want to sleep, and that's because of prolactin.
The thyrotropin-releasing hormone (TRH) regulates the release of prolactin and when there's too much, testosterone levels drop.
Dopamine has an inhibiting effect on prolactin. So, more dopamine means less prolactin, and less prolactin, means more testosterone.
And this all starts with Mucuna Pruriens high concentrations of L-DOPA, which make it a potent testosterone boosting ingredient.
But what studies are there to back up these claims?
Several animal studies have uncovered the Mucana Pruriens testosterone boosting benefits in rats.
For example, in this Japanese study (21), the Luteinizing Hormone in rats significantly increased after getting high doses of L-DOPA (1000mg/per day) over a 7/14 day period.
Great news if you're a rat, but what about us humans.
Glad you asked because, this study (22) by the University of Lucknow, India found Mucuna Pruriens improves fertility in men by its effect on the hypothalamus-pituitary-gonadal axis.
The study involved two male groups, one infertile and the other fertile.
Both groups were supplemented with a daily dose of 5gms of Mucana Prurien seed powder for 90 days.
The results showed the infertile group's testosterone levels increased by as much as 38%, as well as a 41% boost in their LH levels.
Although less, the fertile group also experienced a 27% increase in testosterone and 23% increase in LH levels.
One study discovered that Mucana Pruriens cortisol suppressing properties helped infertile men improve the quality of their semen.
The same study (23) also found Mucana Pruriens improved the quality of semen in infertile men by reducing the stress hormone, Cortisol.
As you can see, Mucana Pruriens can undoubtedly help boost T-levels and increase the quantity and quality of sperm in both infertile and fertile men.
Based on these studies its well worth choosing a testosterone booster that includes Mucana Pruriens in its formula.
