Many men, myself included, are looking for a safe and effective way to boost their natural testosterone. Increased testosterone levels have many benefits, especially for men who are over 35. It will make you not only look better, but feel better as well.

So, what are the safe, legal and effective ways that we men have to boost our natural testosterone levels?

I want to take a look now at 8 popular testosterone enhancing sports supplements. You may or may not have heard about all 8, but do you know if they actually work? This article will answer that question for you.

Here are the 8 testosterone boosters we will be looking at:

1. ZMA
2. Tribulus Terrestris
3. Fenugreek
4. Activate by Designer Supplements
5. 6-OXO
6. Avena Sativa
7. Tongkat Ali
8. Yohimbe

ZMA – ZMA is a designed mineral formula comprised of zinc monomethionine aspartate, magnesium aspartate and vitamin B-6. They are combined in specific ratios to supposedly maximize the effectiveness of ZMA. A 1999 study showed increases of up to 30% in free and total testosterone during an 8 week study of NCAA football players. However, this study was conducted by one of the owners of the company that holds the patent on ZMA. Not completely unbiased.

ZMA may have helped testosterone levels because the mineral zinc and magnesium play important roles in the production of anabolic hormones, especially testosterone. The study participants were shown to have borderline deficient levels of both minerals at the beginning of the study, so raising their levels to normal could have accounted for the rise in testosterone.

I wouldn’t rule out ZMA completely, most people in the U.S. are deficient in both zinc and magnesium. If you are slghtly deficient in zinc and/or magnesium ZMA could increase your testosterone production by bringing your levels back to normal. 8 out of 10 stars!

Tribulus Terrestris – This is a weed that grows in temperature and tropical climates and has been used for centuries to increase libido in males. Does it also increase testosterone levels as many supplement companies would have you believe? That depends on who is taking it.

Tribulus terrestris HAS been shown to increase testosterone levels by as much as 30%, but only in individuals who have low testosterone levels to begin with. It will raise your levels to normal, but it will not raise them if you already have normal testosterone levels.

So, tribulus terrestris is partially useful as a testosterone booster. If you are overtrained, if you are on a low calorie ‘cutting’ diet or if you are recovering from steroid or prohormone use (as part of PCT) tribulus terrestris can be useful n raising your testosterone levels. Don’t expect that it will give you super high test levels or significantly increased libido. 6 out of 10 stars!

Fenugreek – Fenugreek is an herb found primarily in Indian food. It has historically been used by nursing mothers to increase milk production. Studies on fenugreek are scant, but it has been shown to decrease blood sugar levels of type II diabetics.

Fenugreek has become popular recently as a testosterone booster in bodybuilding supplements. There is no proof at all that this is true. Because of it’s effect on blood sugar levels it could be useful as a cutting supplement used to lower blood sugar and insulin spikes. 2 out of 10 stars!

Activate – Activate is a fairly new product from Designer Supplements that claims to increase free testosterone levels in the body. The active ingredient has been trademarked under the name Divanil and is an extract of the stinging nettle plant.

Your body has both free testosterone and bound testosterone. Only the free testosterone is of use to you in building muscle. So, you may have high testosterone levels, but if all of it is bound it is useless to you for muscle building.

Your body controls the amount of free testosterone through a protein called Sex Hormone Binding Globulin (SHBG). The SHBG binds to your free testosterone making it unavailable for muscle building. Activate works by inhibiting (decreasing) the SHBG in your body. This means more of your testosterone is free to help with your muscle building.

There are no studies confirming the rise in free testosterone levels, but there are studies showing that lignans from stinging nettle extract inhibit SHBG and user feedback is almost unanimously positive. I myself have used Activate several times and find that it increases focus in the gym, hardens my muscles and also increased libido. 10 out of 10 stars!

6-OXO – This is a product developed and trademarked by Ergopharm. The active ingredient is 4-etioallocholen-3,6, 17-trione. There have been several studies to date that validate 6-OXO as a testosterone booster. These studies while small have shown average free testosterone increases of 126%. Longer term studies are still underway, but initial reports are positive. 9 out of 10 stars!

Avena Sativa – Please don’t believe the hype behind avena sativa. Avena sativa is the scientific name for wild oats. While I enjoy oatmeal as a good source of carbohydrates it is not a testosterone booster? No way! There are no studies or historical evidence that avena sativa does anything to increase testosterone levels. 0 out of 10 stars!

Tongkat Ali – Tongkat ali is an extract from the root of the Eurycoma shrub found mainly in Malaysia and Indonesia. It is also called Longjack and Eurycoma Longfolia.

It has been used for centuries in southeast Asia to boost libido and as an aphrodesiac. Studies confirm that it works very well, increasing both sexual function and endurance as well as libido.

Researchers are unsure how Tongkat ali works, but they believe that it both increases testosterone production and increases free testosterone. Like a 1-2 punch. Common effects from Tongkat ali are increased well being, better body composition, increased libido and increased focus and aggression.

Tongkat ali does take some time to start working so it may take up to 2 weeks before you start to see its effects. You also need to make sure you are getting an extract of the root powder and not just root powder. The extract is more expensive, but necessary. 8 out of 10 stars!

Yohimbe – Yohimbe has been used as a testosterone booster as well as a fat loss aid. While it does aid in fat loss through several mechanisms, there is no proof that it boosts testosterone levels.

It is likely that people believe it increases testosterone because it does increase libido, however the libido increase is not due to a testosterone increase. Yohimbe works partially as a vasodialator which means it opens up blood vessels, especially those in the lower extremeties such as the genetalia.

Yohimbe has also been shown to have several negative and possibly dangerous side effects and many physicians advise their patients not to take yohimbe because of these side effects. 3 out of 10 stars!

Protein is, by far, the most important nutrient in a bodybuilder’s diet. Red meat, fish and dairy products are the primary sources of this protein. Most, if not all, bodybuilders also consume a large quantity of protein powder supplements in order to meet their daily requirement of protein.

The popularity of supplemental protein has grown for many reasons. Let’s look at a typical 200 pound bodybuilder. Our bodybuilder must consume 1 to 1.5 g of high quality protein per pound of body weight each day. That works out to 250-300 grams of protein every day. This protein intake should be divided into 5 or 6 meals to be consumed throughout the day. Six meals per day, our bodybuilder needs to consume an average of about 40 g of protein at each meal.

Let’s look at the protein content of some common bodybuilding foods:

8 ounces of various steaks: 45g protein, 10g fat

6 ounces chicken breast: 40g protein, 2g fat

6 ounces Turkey breast: 30g protein, 1g fat

8 ounces pork chop: 30g protein, 6g fat

4 ounces hamburger (90%): 15g protein, 10g fat

1 can chunk light tuna (6.25 oz): 40g protein, 1g fat

1/2 cup cottage cheese: 12g protein, 2g fat

1 large egg: 6g protein, 3g fat

Using a combination of these excellent foods, you can easily meet your requirements for 3 or 4 of your 6 meals each day. Preparing six meals every day utilizing these foods, however, would cost a lot of time and money!

This is why supplemental protein comes into play. Protein “shakes” are an extremely convenient, fast and cheap meal to help you get two or three more servings of protein a day. As an added bonus, the better quality protein powders taste excellent! Protein powder supplements come in many different types, formulations, and flavors.

Protein consists of amino acids, which are the very building blocks of muscle tissue. There are 22 amino acids, some of which the body can make on it’s own, and some that must be provided in the diet. The combination of the different amino acids in a protein source is called the amino acid profile. Each type of protein has a different amino acid profile. This is why it is best to eat a variety of proteins sources as well as use a variety of protein powder supplements. The most popular types of protein powders are whey, casein, egg, and soy.

Whey protein is by far the most popular and most heavily used protein supplement. Whey protein is cheaper per gram of protein than most other types of protein. Whey protein is absorbed very quickly by the digestive system and reaches the muscles quickly. Whey protein is best used as the first meal of the day because your body has not had any protein for many hours during the night and you want to get it in your bloodstream right away. Use whey protein immediately following a workout because this is the most important time to take in a large quantity of protein and you want to get to your muscles as soon as possible.

Casein protein is a bit more expensive than whey protein, but is absorbed at a much slower rate. This fact makes casein protein the supplement of choice right before bedtime. A generous serving of casein protein can provide your muscles with a steady supply of protein for 5 to 6 hours as opposed to 1 or 2 hours for whey protein. Casein protein is also an excellent choice if you think it may be a long time before your next protein serving.

Egg protein is not nearly as popular as whey or casein mostly because of its cost. It is, however an excellent supplement with a high BV (Biological Value is used to indicate how much of the protein is actually used by the body) and excellent amino acid profile. I like to add egg protein to my whey and casein shakes for variety or occasionally as a substitute.

Soy Protein, which comes from the soy bean, while popular with vegetarians, is slightly inferior to whey, egg and casein protein. While this may be true based upon its incomplete amino acid profile, it is still an excellent way to add variety to your protein intake, and is recommended as an addition to your overall supplement diet.

Protein supplements are by far the most popular supplement in the bodybuilding world. I suggest purchasing from a name brand to be sure you are getting a quality product. If you are new to bodybuilding and supplements, some of the top selling quality brands are BSN, MuscleTech, Optimum Nutrition, Twinlab, Cytosport, EAS, and the list goes on. I recommend trying several different brands and flavors until you find one you really like. I will occasionally switch brands just for variety and possibly if I come across a good sale!
