Testosterone Support: A Brief Review

I believe every man at some point has looked into ways to enhance their testosterone levels. Whether it be for athletic performance, libido, or just general well being, Testosterone boosting seems to be mentioned moreso now than ever before. There are a variety of herbals/ supplements that tout benefits in this area, whether it be in boosting production initially or acting to protect testosterone from being converted into other chemicals. The following is a brief list of a few more popular herbals/supplements divided by their basic action.

Potential Testosterone Boosters

• Tribulus Terresteris: Also know as puncturevine. Potential benefit of increased testosterone levels via the body’s natural production methods. Be sure if choosing tribulus to select a standardized product for the best effect.
• D-Aspartic Acid: Nonessential amino acid that has a myriad of benefits, including potential natural testosterone boosting benefits similar to tribulus.
• DHEA(Dehydroepiandrosterone): A precursor to testosterone in the body. It appears that after age 30 the body’s levels of DHEA start to decline at a steady rate, falling to half the normal levels by age 40. Recently the media has been giving DHEA extra attention due to potential anti aging effects. I would only suggest this supplement to individuals over 30, and by a physician’s direction.

Testosterone Support

• Eurycoma Longifolia(Longjack, Tongkat ali): From the research I have done this supplement can be categorized in both areas. Reports state multiple benefits for testosterone, both in production and in protection from the negative effects of estrogen on testosterone.
• Epimedium(Horny Goat Weed):Active phytochemical, Icariin. Potential benefit of binding to SHGB (Sex Hormone Binding Globulin), which usually binds to testosterone and inhibits its anabolic effects.
• DIM(Diindolylmethane): From cruciferous vegetables(cauliflower, broccoli, etc…). Potential action to reduce “bad” estrogens and increase “good” estrogens. There are varying debates on this supplement, and until more solid evidence can be provided I would consider another estrogen management supplement for the time being. I still wanted to mention this supplement since much of the research I have seen seems very promising.
• Chrysin: Aromatase (estrogen producing) inhibitor. Many circles consider this isoflavone the “king of estrogen blockers”.

This is just a very basic review, but I wanted to talk about a few of the more popular supplements marketed for testosterone support. If you research some of these supplements you will see how many differing opinions you will find. I chose to include the most consistent information I could find. If anyone would like to add any more herbals/supplements to the above categories, feel free to add by comments. Please no company blends, include specific herbals/supplements only. I hope this information helps in your future supplement choices.

The Mystery of Supplement Labeling

I think everyone at some point has taken an interest in the supplement market. Many of us have also compared labels of competing brands, and have been completely confused by each products way of describing its fine details. Even seasoned veterans of the supplement market can become mislead by the various descriptions. I myself have just recently become aware of a few practices that may have caused me to purchase one product under the assumption it was providing an amount I was interested in using. I hope these next few paragraphs will enable the consumer to be better informed.

Powder Supplements (Protein)

• Always look for “serving size”. Many companies advertise on the front of the container “40g whey protein”, but that may be in 2+ scoops of product while a higher quality competitor may provide the same amount in a single scoop.
• Be aware of how many grams each serving/scoop contains. Many companies use a traditional 31g scoop, but many others do not. Do some minor math and make sure you are getting the best product for the best price.
• Ingredient listings are your friend. Listings are designed from highest amount of product, to least amount per serving. You may see “Whey Protein” on the front label, and then notice it’s halfway down the list in the ingredient listing. Also, there are different degrees of quality for proteins. Whey isolate, Whey Concentrate, Hydrolyzed Whey protein… The list goes on and on. Be sure to do a little research before you make a decision, and please if you go to a retail chain don’t fall for sales mumbo jumbo. Be the informed consumer, or use sites like Bodybuilding.com, they provide valid information from professionals in the field along with customer reviews.
• Be aware of fat, cholesterol, sodium, etc… Some powders are great, but then are loaded with 60mg or more of cholesterol. This doesn’t sound like much, until you take 3-4 servings per day. Many protein powders contain zero fat/ cholesterol, just skim over what is offered and I’m sure you will find a few.

Other Deliveries (Tablets, Capsules, Caplets, etc…)

• This section was taken from ISSA’s sports nutrition certification manual, they did an excellent job at explaining the details so I will be pulling a majority of the following information from there.
• Ex. 1: Each Capsule Contains:              L-Arginine .........500mg                                                   

                                                                        L-Ornithine …………. 500mg

1. Pretty straightforward, each Capsule will provide 500mg of each compound.

• Ex. 2: Each Capsule Contains:            L-Arginine hydrochloride …… 500mg

                                                                        L-Ornithine hydrochloride …… 500mg

1. This is a little more deceiving, what is being stated is that there is 500mg of the entire compound L-arginine hydrochloride, not just the arginine. You may only receive 60% of the total being actual arginine.

• Ex. 3: Each Capsule Contains:        L-Arginine(HCL or Hydrochloride) … 500mg

                                                                     L-Ornithine(HCL or Hydrochloride) .. 500mg

1. Parentheses informs you that the capsule contains 500mg or arginine and ornithine in the form of hydrochloride, which means you are getting the full 500mg per capsule as in example 1.

As you can see the supplement market has many ways of describing their products. Hopefully the above information will allow you to be better informed on what to look for, and allow for more successful purchases. I hope this information helps, and as always if you have something to add please comment.
