Hydroxyl Methylbutyrate (HMB) for strength and getting lean

HMB has been widely publicized and has been one of the more popular supplements for over a decade. HMB is a metabolite of the branch chained amino acid leucine. With claims like increased strength, muscle size, recovery and fat oxidation, it sounds too good to be true. In fact, a publisher of a very successful magazine referred to using HMB akin to using the anabolic steroid deca durabolin. Unfortunately, the claims made about HMB don’t seem to hold up in the research.

A study published in the Journal of Strength and Conditioning, performed a met-analysis of 9 studies. The analysis was comprised of 394 subjects between the ages of 21 and 25. Some of the subjects had training experience and some didn’t.

The major findings of this meta-analysis are that HMB supplementation results in a small, beneficial increase to overall strength in untrained lifters but has a negligible effect on trained lifters. Furthermore, in untrained lifters, HMB results in a small to possibly moderate increase in lower-body strength, but it has only a negligible effect on upper-body strength. In contrast, all strength outcomes are insignificant in trained lifters. In both trained and untrained lifters, the effect of HMB supplementation on body composition is negligible.

In my view HMB is a waste of money. The only gains made were small strength gains in untrained individuals? Why would any researchers analyzing a supplement, looking for strength or lean body mass gains, use untrained individuals? They are going to make gains, especially in the first few months, just by working out. I’m amazed at how so many studies are poorly performed and yet, are still published.

Testosterone’s time sensitive side effects

Low testosterone (T) symptoms may include low sex drive, erectile dysfunction, fewer sexual thoughts, mood problems, fatigue, loss of muscle, poor concentration, sleep disturbances, and fewer morning erections. Low T is also associated with several chronic medical conditions, including obesity, diabetes, osteoporosis, depression, and cardiovascular disease.

Men who get treated for low T have a very positive experience. The changes in appearance and mental state can be very profound. Interestingly, these positive changes associated with T therapy, have been found to occur at different times. A study from the University of Koln in Germany analyzed the relationship of time following administration vs. the effects on sexual functioning and mood on forty subjects. Researchers found sexual thoughts and fantasies occurred within weeks of initiating T therapy. Total number of erections rose steadily and peaked at 9 weeks. Ejaculations per week steadily rose and plateaued over 12 weeks. Depression decreased gradually and leveled off at 6 weeks. Mental concentration improved within the first 3 weeks, but overall mood did not improve until weeks 6 – 9.

Glutathione, the antiaging secret

Have you ever heard of glutathione (pronounced; gloota-thigh-own)? Neither has almost anyone else. Many researchers say it’s probably the most important substance we require to stay healthy. Many go as far to say it’s the secret to prevent aging. So where’s Oprah, and the rest of the media? A quick search of the term “glutathione” on PubMed.gov reveals 94,117 scholarly articles, reviews and abstracts.

Present in every cell of our body, glutathione levels just might be one of the best biochemical markers there is; the higher your glutathione levels are the healthier you will be. Glutathione deficiency is found in almost all patients with extreme illnesses, e.g., cancer, heart disease, Parkinson’s disease, Alzheimer’s, arthritis, liver disease, diabetes and more. In fact, researchers are concluding glutathione deficiency may play a role in patients with schizophrenia. In cerebrospinal fluid of drug-free schizophrenic patients, a significant decrease in the level of total glutathione was observed as compared to controls. EJN

Glutathione’s importance to a properly functioning immune system has been shown in many studies. According to Dr. Gustavo Bounous, “The limiting factor for the proper activity and multiplication of our lymphocytes (white blood cells) is the availability of glutathione”.

Every day our bodies are exposed to stress, pollution, infection, drugs (illicit or licit) and alcohol, poor diet, infections and injury, which drain our bodies of glutathione; this depletion leaves our bodies susceptible to high levels of oxidative stress, which leads to aging, disease and eventual death. I predict that concern about glutathione levels will eventually be on par with other preventative health issues.

Health Benefits of Acai Berry Supplements

Acai (pronounced AH-sigh-EE) is a palm tree that can be found in South American and Central America. Countries such as Brazil and Belize are rich in acai. Other names for acai include acai extract, assai, assai palm, acai fruit, acai palm, cabbage palm, Euterpe oleracea, Amazon acai, Amazon acai berry, and of course, acai berry.

According to the National Institutes of Health (NIH), acai contains chemicals that are antioxidants. Antioxidants are thought to protect body cells from the damaging effects of chemical reactions with oxygen (oxidation). According to some research, acai has more antioxidant content than cranberry, raspberry, blackberry, strawberry, or blueberry. Because the berries of the tree have such a high level of antioxidants, they are used to make medicine, supplements, powders, and drinks. The berries can be used in foods and they are also eaten whole.

Many people use acai berry supplements to improve arthritis, lower cholesterol, and improve general health. They are also used to promote weight-loss and they are used in anti-aging creams, shampoos, and conditioners. There are few studies to support the benefits of acai berry, but studies do demonstrate the protective properties of antioxidants.

So far, there are no studies to suggest that acai berry is dangerous. At the same time, there are no studies to support how it might interact with other supplements, herbs, or prescription medications. It is also unknown if acai berry supplements are safe for pregnant women. The issue is not acai berry, it’s the way it may be processed, the amount contained per capsule, if the supplements are made from pure acai, or if the supplements contain other substances or chemicals. Because of this, doctors recommend getting the antioxidants you need from food.

If you prefer acai, it’s best to eat the berries raw or make your own homemade juice as most store bought juices contain loads of sugar or additives. The problem is, finding raw acai outside of South or Central America can be tricky. Use your favorite search engine to seek out importers. It might be expensive, but if you want to enjoy the benefits of raw acai berries, this is your best bet.

Other Foods that Contain Antioxidants

Antioxidant substances include beta-carotene, lutein, lycopene, selenium, vitamin A, vitamin C, and vitamin E. Antioxidants can be found in fruits and vegetables, nuts, grains, poultry, and fish. Some of the most antioxidant rich foods include:

-Red Beans
-Kidney Beans
-Russet Potatoes
-Black Beans
-Artichoke Hearts
-Pecans
-Black Plums
-Dried Prunes
-Pinto Beans
-Sweet Cherries
-Cereal (oats, barley)
-Cabbage
-Hazelnuts
-Spices (cinnamon, cloves, oregano, cayenne pepper)
-Apples

Antioxidants can also be found in some meats, such as beef. For more information about acai and other antioxidants, visit Medline Plus, a service of the U.S. National Library of Medicine National Institutes of Health.

Is Taking Fiber Supplements Risky?

If you’re healthy, taking a daily fiber supplement isn’t risky. Fiber supplements are only dangerous if you are on medication or if you have intestinal problems. Some doctors also believe that fiber supplements can be harmful if you have diabetes. Fiber supplements can aggravate intestinal conditions, they can decrease the absorption of medications, and according to some doctors, they can reduce blood sugar levels. For healthy individuals, however, a daily fiber supplement has a number of benefits.

It is estimated that only 5 percent of Americans get enough fiber in their diets. Although fresh fruits, vegetables, grains, beans, and legumes are the best sources of fiber, in some cases, access to these foods is limited. Food deserts are a reality and thanks a shaky economy, many families just can’t afford to buy fresh fruits and vegetables on a regular basis. In these cases, an inexpensive alternative such as fiber supplements may be the only option.

According to the Mayo Clinic, a daily fiber supplement can help normalize bowel function, maintain bowel integrity and health, lower blood cholesterol levels, help control blood sugar levels, and aid in weight loss. Some studies show that fiber may also help prevent colorectal cancer.

If you don’t think you’re getting enough fiber through healthy foods, consider taking a supplement. Before you choose a supplement, it is important to understand the different types of fiber.

Fiber is commonly classified into two categories: those that don’t dissolve in water (insoluble fiber) and those that do (soluble fiber).

Insoluble fiber. This type of fiber promotes the movement of material through your digestive system and increases stool bulk, so it can be of benefit to those who struggle with constipation or irregular stools. Whole-wheat flour, wheat bran, nuts, and many vegetables are good sources of insoluble fiber.

Soluble fiber. This type of fiber dissolves in water to form a gel-like material. It can help lower blood cholesterol and glucose levels. Soluble fiber is found in oats, peas, beans, apples, citrus fruits, carrots, barley and psyllium.

When purchasing a fiber supplement, be sure to read the labels to make sure you’re taking the right kind for your individual needs. The three types of supplements are psyllium, methylcellulose, and polycarbophil.

Psyllium bulks up the stool by breaking down in the gut. Here, it becomes a food source for the bodies beneficial “good bacteria.” This process makes the stool easier to pass. Psyllium can be taken every day. Brand names include Metamucil, Fiberall, Hydrocil, Konsyl, Perdiem, and Serutan.

Methylcellulose is made from plants and it is non-fermentable. This type of fiber creates a softer stool. Brand names include Citrucel, Citrucel Clear Mix, Citrucel Food Pack, Citrucel Lax, and Citrucel SF. This type of fiber can be taken every day.

Polycarbophil is also plant-based and it absorbs water in the intestinal tract. This helps create a bulkier and softer stool. Brand names include Equalactin, Fiber Lax, FiberCon, Fiberlax, Fibernorm, Konsyl Fiber, Perdiem Fiber Caplet, Mitrolan, Fiber Laxative, Fibertab, Polycarb, and Fiberall Tablets. This type of fiber is usually used to treat IBS, constipation, and diverticulosis. If used long-term, it may cause bloating.
