Amino Acids Defined


What are Amino Acids?

Amino acids are organic compounds composed of one or more amino groups, and one or more acidic carboxyl groups, and are the basic building blocks of protein. There have been more than 100 amino acids found in living organisms. Only 20 amino acids are commonly found in animals, the others exist in other biological systems, primarily plants.

Amino Acids are used for growth, maintenance, and repair of cells in the body. Of the 20 amino acids found in animals, 12 of them can be synthesized by the body as needed, and these are referred to as nonessential amino acids. The remaining 8 amino acids, cannot be synthesized by the body, and therefore must be acquired from food or supplement, and these are referred to as essential amino acids.

The 20 amino acids are;

Essential: Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, and Valine.

Nonessential: Alanine, Arginine, Asparagine, Aspartate, Cysteine, Glutamate, Glutamine, Glycine, Histidine, Proline, Serine, and Tyrosine.

Why Supplement Amino Acids?

Arginine
Arginine is a nonessential amino acid, and it is responsible for the normal function of the pituitary glands. Arginine is used to compose the compound nitric oxide, which has many beneficial effects. Nitric oxide reduces blood vessel stiffness and increases blood flow, improving blood vessel function. Arginine supplementation is effective for lowering cholesterol, regulating blood pressure, erectile dysfunction, enhancing sexual feeling in both men and women, improving long term memory, and fighting infections.

BCAA's
Branched chain amino acids or BCAA's are the essential aminos leucine, isoleucine, and valine. BCAA's are considered to be among the most beneficial and effective supplements in any sports nutrition program. They are needed for the maintenance of muscle tissue and appear to preserve muscle glycogen stores, and help prevent muscle protein breakdown during exercise. BCAA supplements may be used to prevent muscle loss at high altitudes, prolong endurance performance, and to provide the needed amino acids not provided by a vegetarian diet.

Carnitine
Carnitine is made in the body from essential amino acids, Lysine and Methionine, and is needed to release energy from fat. Carnitine is commonly used to promote growth and development, fat-burning, increasing energy, and improved resistance to muscle fatigue. Individuals, who supplement Carnitine while engaging in strenuous exercise routines, are less likely to experience muscle soreness.

Creatine
Creatine is made up of three amino acids - Arginine, Glycine and Methionine. Our liver combines these three amino acids to make creatine. 95% of the creatine in our bodies is stored in the muscles. Creatine provides instant additional energy to the muscles. Unlike the energy provided by carbohydrates or fats, which take some time to convert to useable energy, the energy for creatine can be converted almost instantaneously. Creatine also increases muscle volume, by pulling water into the muscle cells, and decreases muscle burn during exercise. Creatine also increases protein synthesis, meaning greater muscle gain.

GABA
GABA or gamma-amino butyric acid is a synthetic compound designed to lower fat levels and increase lean muscle tissues by stimulating the brain to secrete more human growth hormone. Studies have shown GABA to be effective stimulating the secretion of HGH, and has been clinically proven to help the pituitary gland secret HGH.

Glutamine
Glutamine is a nonessential amino acid. The body relies on glutamine as cellular fuel for the immune system. After intense work outs, glutamine levels in the body are reduced by as much as 50%. Glutamine supplementation can minimize the breakdown of muscle tissue and improve protein metabolism. Studies have shown that with as little as 2 grams of free-form L-glutamine supplement, growth-hormone levels can increase up to a 400%.

Lysine
Lysine is an essential amino acid. Lysine is important for proper growth and the production of carnitine, a nutrient responsible for converting fatty acids into energy and helping to lower cholesterol. Lysine helps the body absorb and conserve calcium and maintaining the correct nitrogen balance in the body and maintaining lean body mass. Lysine is useful for patients recovering from injuries and recovery after operations, and to help maintain healthy blood vessels. It also assists in fighting herpes and cold sores.

NAC
NAC or n-acetyl cysteine is an altered form of the amino acid cysteine. NAC may assist to break down mucus and used in the treatment of bronchitis - for this reason it is used as an inhalant in hospitals in the treatment of bronchitis. It assists the body in synthesizing glutathione and helps to protect the body from acetaminophen (the ingredient in Tylenol).

SAM-e
SAM-E is a derivative of the amino acid Methionine, and is used in the treatment of many conditions including depression, liver disease, osteoarthritis, fibromyalgia, schizophrenia, and migraine headaches. SAM-E is also commonly referred to as S-Adensyl Methionine, L-Methionine, Adomet, and Ademethionine. The liver produces as much as 8 grams of SAM-e a day. Liver disease, osteoarthritis, and extensive use of prescription, and over the counter medications, can inhibit the body's production of SAM-e.

Tyrosine
Tyrosine is a nonessential amino acid. Tyrosine is needed to make epinephrine, norepinephrine, serotonin, and dopamine, all of which work to regulate mood. Deficiencies in tyrosine, therefore, have been associated with depression. Taken ahead of time, tyrosine may suppress typical bodily reactions and feelings from stressful situations like surgery, emotional upset, and sleep deprivation.

8 Ways to Boost Your Testosterone


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. The additional zinc and magnesium could bring your levels up to normal and thus help your natural testosterone production. 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.

Recently, fenugreek has found its way into bodybuilding supplements as as testosterone enhancer. 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. Tasty and a good source of carbohydrates to be sure, but 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.

Traditionally it has been used as an aphrodisiac as well as a libido booster in SE Asia. 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!

Joint Pain Relief


If your joints are constantly killing you, here are three suggestions:

1. Traumeel is a product that has been used for years in Germany to relieve pain. I have not been overly impressed with the ointment; however, my colleagues claim that injecting it is the way to go. Dave Tate at Elite Fitness sells both forms. Let me just add the mandatory precaution here: make sure to have a qualified medical practitioner administer the injection if you go that route.

2. There's a product called Nu Joint Matrix that you spray on topically ... and guess what, this stuff seems to work! To test it for yourself, perform multiple sets of heavy eccentrics to induce muscular soreness and then apply the spray to only one side. You will notice the difference in no time. In fact, the company claims that it kicks in within 10 minutes of application. It smells like Pledge on your body but works more like Windex does in the movie My Big Fat Greek Wedding!

3. Dr. D's Joint Support is by far the best joint supplement on the market. It attacks through several mechanisms - believe me, Dr. Di Pasquale makes sure that no stone is unturned! I recommend that you start with 5 tablets three times a day with meals. You can eventually wean down to twice daily (with breakast and dinner), and finally once a day (with breakfast) - the duration of each phase depends upon the severity of your pain as well as your financial status!

Now, imagine taking all three (injectable, topical and oral) applications at once! It should go without saying that regular consumption of Omega-3 fats (i.e. fish oil and flax seed oil) will help keep those joints well-lubed. Also, forget Tylenol (Acetiminaphen) and NSAIDs such as Advil (Ibuprofen) or Aspirin (ASA.) Research shows that on top of the havoc they pose on the gut's inner lining, they hinder protein synthesis.

The Best Protein Powder


What is the best protein powder to buy? I get this question all the time, and really, there is no best protein - many are very good for different reasons! In my opinion, it is futile and possibly detrimental to stick to only one brand for the following reasons:

a) I always recommend that you cycle your supplements so that your body does not get used to them thereby decreasing their effect,

b) for variety sakes alone, it breaks the monotony and allows you to try different brands,

c) to take advantage of the unique qualities offered by various brands, and

d) it is a good idea to switch the powders you use on a frequent basis to not develop any food intolerances or even worse allergies (I have an article coming out on this subject in the near future.) A blend that combines various protein sources (i.e. casein, egg, whey, and even beef if you can find it) is your best bet. I highly recommend the following: MD+ Myosin Protein Complex, Beverly International Muscle Provider, Biotest Low-Carb GROW!, and Dorian Yates Approved ProPeptide.

High-quality whey protein powders are excellent choices for post-workout nutrition since they get into your system fast to feed those depleted muscles. Casein, on the other hand, is a slow releasing protein as it recurdles into a solid in your gut prolonging digestion - this would be an ideal choice prior to your workouts or before going to bed.

Anyhow, as far as whey powders are concerned, amino acid complex profile determines quality. I have in my possession a list of protein powders that were analyzed for quality by an independent laboratory, but since I don't want any of these companies breathing down my neck, I will only divulge that information to my clients. Remember one thing, you get what you pay for! Keep that in mind. Also, some people are quite sensitive to aspartame and lactose so you will have to find free versions of those. Taste will ultimately determine whether you purchase that powder again. Write in with some of your feedback on these products - I'd love to hear your comments.

One more thing, you could even mix protein powder into other foods to up the protein content and improve the flavor. Mixing protein powder in (slow-cooked) oatmeal is one option, but here's another. I call it my "bedtime concoction." Add a scoop of Xtreme Formulations Ultra Peptide
(vanilla) to a mixture of ricotta (whey) and cottage (casein) cheese. Not only does this provide both an anabolic and anticatabolic effect during sleep, it also tastes amazing - it's like eating the cream filling of a cannoli without the pastry shell! Try it.
