Branched-Chain Amino Acids- Not Just For Building Muscle

Amino acids are the building blocks of protein. The words “branched chain” simply refers to their chemical structure. They are amino acids that have one carbon atom bound to more than two other carbon atoms.

A study was published in the journal Cell Metabolism which concluded that branched chain’ amino acids (BCAAs) may increase life span by inducing mitochondrial biogenesis, which is the spontaneous generation of new mitochondria.[1] Mitochondria are known for supplying cellular energy. The study also concluded that BCAAs upregulate (make more of) the expression of a pro-longevity gene.[2,3,4]

The BCAAs are leucine, isoleucine and valine. These are essential amino acids. Each of these three benefit many biological processes in our body. But they are best known for their ability to build our muscle mass.[5]

Isoleucine is needed for the formation of hemoglobin and to regulate blood sugar and energy levels. It plays an important role in muscle strength and endurance and is a source of energy for muscle tissues. Isoleucine also promotes muscle recovery after an intense workout.[6]

Leucine facilitates healing by modulating the release of natural pain-reducers called enkephalins. Leucine is a precursor of cholesterol and also increases the synthesis of muscle tissue.[7]

Valine is essential in muscle growth and development, muscle metabolism, and the maintenance of nitrogen balance in the body. It can be used as an energy source in place of glucose. Valine has also been used as a treatment for brain damage caused by alcohol.[8]

The BCAAs are formed during photosynthesis when sunlight shines on a green plant. Since BCAAs originate from plants, and eating low on the food chain is the least polluted source of nutrition, I look towards plants to get mine. Beans and peas are a good source for all of the BCAAs. And if you’re interested in protein powder, pea protein powder happens to be high in BCAAs. My favorite source of the BCAAs is Warrior Blend, from SUNWARRIOR.

Acid Reflux, Treat the Cause, Not the Symptoms

Stomach acid is essential for good digestion and absorption of nutrients from your diet. Suppressing stomach acid only treats the symptoms, it does not treat the cause of the disease. In fact, it can actually make things worse. Taking acid blocking drugs long enough will cause numerous nutrient deficiencies, including vitamin, mineral, and especially vitamin B12 and amino acid deficiencies.

Studies have shown that people who take acid blocking drugs long term, may end up with a variety of illnesses including osteoporosis, hip fracture, IBS, fatigue, nerve damage and eventually dementia. Long term use can also lead to an overgrowth of clostridia in the small intestine that can be life threatening.

Stomach acid, also called hydrochloric acid (HCL) is needed for both, separating vitamin B12 from food to make it absorbable and also for breaking down protein rich food so that the amino acids can be absorbed. Not enough amino acids can lead to depression, insomnia, brain fog, anxiety, trouble building and maintaining muscles and more. Amino acids are precursors for essential neurotransmitters which are needed for proper brain function.

Stomach acid is essential for killing bacteria and other pathogenic organisms that might be ingested while eating or drinking. If the stomach acid is too low, these pathogens can colonize in your intestines and cause many health problems.

When pathogenic organisms take up residence in your digestive tract, they can create gas and bloating while feeding on the food you have eaten. The pressure from the gas and bloating can push up through the stomach and then through the upper stomach valve (esophageal sphincter) causing acid reflux.

A urine test or breath test for small bowel bacterial overgrowth can diagnose the presence of certain strains of bacteria.

Hiatal hernia can also cause acid reflux. This can be diagnosed with an x-ray. Extra fat around the midline can also contribute. Stress is another contributing factor.

Food allergies to gluten and dairy products may also contribute to acid reflux. I suggest completely eliminating these two foods for a month or so and see if it makes a difference. Other food allergies may also be a factor.

Nutritional deficiencies can also lead to acid reflux. If you are on a low sodium diet you might become deficient in the minerals sodium and chloride. Zinc, magnesium, vitamin C and B vitamins are also needed to have a properly functioning stomach.

Helicobacter pylori, is another common cause of acid reflux. However, unless you go to a holistic or functional medicine doctor, you most likely will not get tested for it unless you have an ulcer. H-pylori can be diagnosed with a simple stool test.

Numerous holistic and functional medicine doctors have been testing their clients who have acid reflux and finding that most of them have low stomach acid levels. Not high levels!

The following is an example of how low stomach acid can lead to acid reflux.

When the acid level in the stomach is too low, the upper stomach valve might not stay closed and the acid from the stomach can leak up into the throat. Our body needs to sense enough HCL in the stomach in order for the upper valve to stay closed properly. Note that in this case, acid reflux is caused by low stomach acid and not by high stomach acid. It is very often the case that people identify acid reflux as having too much stomach acid while most of the time it is caused by not enough stomach acid.

 

Traditional medical doctors are trained to prescribe acid blocking drugs to treat the symptoms and seem to overlook the dangers of using these drugs. Instead they should be testing the person’s stomach acid level, testing for microbial overgrowth or looking for other causes.

The gastric analysis by radio telemetry test is the most accurate way to measure stomach acid. One just needs to swallow a small capsule with a radio transmitter that measures the pH of the stomach. The result of this test provides you with a graph showing your pH levels at regular intervals over time. If the test shows the HCL level to be low, a betaine HCL supplement can be taken with meals to raise the acid which may keep the upper valve closed when food is present.

There are also two other tests. These can be done at home but are not very accurate. The baking soda test is performed by drinking ¼ teaspoon of baking soda mixed into 5 ounces of water first thing in the morning after waking up. Because the baking soda is very alkaline and your stomach should be very acidic, it will produce carbon dioxide gas that causes burping. You need to measure the exact amount of time that passes from the time you drink the solution until the time that the burping starts. The result gives you an idea of the amount of HCL in the stomach. If it takes more than five minutes to start burping, in may mean that you have low stomach acid. Please note that this test is not always accurate because there are many variables that can give false results.

The betaine HCL test for low stomach acid is the most reliable at home test you can perform. The test is done by taking a betaine HCL pill in the middle of a protein rich meal. If there is no burning sensation after the meal, then do the same thing at your next protein rich meal. If you do this several times and there is no burning sensation, most likely you have low stomach acid.

You may then take 2 pills in the middle of your next protein rich meal and wait to see if there is a burning sensation. Again, if there is no sensation, do the same thing at your next protein rich meal. You can raise the amount of pills by one after every few protein rich meals and see how many pills it takes to feel the burning sensation. When you finally get to the point that you feel the burning, you should then take one less pill during the next meal.

Now that you have determined how many pills your body needs, continue to supplement the HCL with protein rich meals. Over time, your body should need less and less of the HCL supplements as your stomach acid levels normalize. Eventually, you should be able to go off the supplement and not have reflux if the reflux was caused by low stomach acid.

If you have acid reflux, no matter what the cause, it is important to avoid overeating. You will also need to avoid acidic food items such as tomato sauce, fried food, soda, coffee, alcoholic beverages, spicy food and citrus. It is also very important to not eat for a few hours before lying down.

I suggest working with a qualified practitioner who can help you find the cause of the reflux and then slowly wean you off acid blocking drugs. Quitting acid blocking drugs can be dangerous if not supervised by an experienced doctor.

And last thing I would like to share is that there are nutritional supplements that can help. Probiotics are essential to colonize the intestines with good bacteria. DGL (deglycerized licorice) can help with the symptoms. Magnesium is an important nutrient for the proper function of the valves at the top and bottom of the stomach. These valves are actually muscles and muscles need magnesium. And a high quality multivitamin and protein supplement will help replenish nutritional deficiencies that were caused by the acid blocking drugs.

The ‘What’, ‘Where’ and ‘Why’ of Carnitine

Carnitine is found in the bodies of all mammals and many other living organisms. Carnitine’s most well-known function is transporting fatty acids into each cell’s mitochondria (the energy center of the cell) for breakdown into energy.

The word carnitine is composed of the root word carne, meaning flesh. Red meat is a good source of carnitine but according to the National Institutes of Health (NIH), eating red meat can shorten your life span.[1]

Fortunately carnitine can be found in commonly consumed plants. There are a variety of sources including nuts and seeds. The following list has been compiled using radioisotopic technology to determine the carnitine content in common foods.[2] This list is by no means complete.

Listing higher sources first:

  • Tempeh 100 g contain 19.5 mg
  • Cod fish 100 g contain 5.6 mg
  • Chicken breast 100 g contain 3.9 mg
  • Whole milk 100 ml contain 3.3 mg
  • Potatoes 100 g contain 2.4 mg
  • Lentils 100 g contain 2.1 mg
  • Avocado one medium sized contains 2 mg
  • Sweet Potatoes 100 g contain 1.1 mg
  • Cottage cheese 100 g contain 1.1 mg
  • Raisins 100 g contain 0.8 mg
  • Whole wheat bread 100 g contain 0.36 mg
  • Carrots 100 g contain 0.3 mg
  • Bananas 100 g contain 0.2 mg
  • Apples (without skin) 100 g contain 0.2 mg
  • Asparagus 100 g contain 0.195 mg
  • White bread 100 g contain 0.147 mg
  • Peanut butter 100 g contain 0.083 mg
  • Rice 100 g contain 0.0449 mg
  • Egg 100 g contain 0.0121 mg
  • Orange juice 100 ml contain 0.0019 mg

When carnitine occurs in animal tissue, it is synthesized from the amino acids lysine and methionine. Humans synthesize carnitine in their bodies from these amino acids in the same manner that animals do.[3]

According to the National Institutes of Health, healthy children and adults do not need to consume carnitine from food or supplements because the liver and the kidneys produce sufficient amounts to meet daily needs.[4,5,6]

In 1989 The Food and Nutrition Board of the National Academies (formerly National Academy of Sciences) declared that carnitine was not an essential nutrient.[6]

Carnitine deficiencies are rare. Even strict vegetarians and vegans show no signs of carnitine deficiency.[7] The only time I have personally encountered a person deficient in carnitine was when they had been taking CoQ10 in doses of 200 mg a day for extended periods of time. This condition was easily corrected by taking a carnitine supplement and cutting back on CoQ10.

Studies that have been done using carnitine supplements to improve exercise performance show conflicting results. Some studies conclude no significant effect on exercise performance.[8][9] Other studies conclude a beneficial effect on training, competition and recovery from strenuous exercise.[10]

There are two main forms of carnitine supplements, L-carnitine and acetyl L-carnitine (also sometimes spelled acetylcarnitine or ALCAR).

The supplemental form called L-carnitine is usually taken by people trying to lose weight by converting their fat into energy. However, published studies showing the efficacy of using L-carnitine for weight loss are limited.

The form called acetyl L-carnitine is known to be more easily absorbed by the small intestine and is also known for its ability to pass through the blood brain barrier. Studies conclude that senior citizens with age related mental decline taking acetyl L-carnitine improved their mental functioning, especially in those with Alzheimer’s disease.[11][12]

In January of 2016 a meta-analysis of randomized controlled trials was published that showed a significant reduction of lipoprotein(a) levels following carnitine supplementation.[13] This is great news for those with genetically high Lp(a) levels because an elevated level of Lp(a) is a risk factor for heart disease and stroke.

One study found benefit for people with pancreatic cancer.[14]  Another study found benefit for people with diabetic peripheral neuropathy.[15]  Studies are ongoing about the use of carnitine supplements to treat various disease conditions.

Rare side effects of supplementing with carnitine include fishy body odor and rash. Taking large doses could result in nausea, diarrhea and cramps. People on prescription medication or those with heart disease, excessive, fatigue or a thyroid condition should talk to a doctor before taking carnitine.

For people who choose to supplement with carnitine I suggest using the product as directed on the label. No advantage appears to exist in taking an oral dose of carnitine greater than two grams at a time because absorption studies indicate saturation at this dose.[16]
