What’s the Difference in Vitamins?

Americans love vitamins. Almost on every commercial break or in every magazine advertisement, a brand of vitamins is being pushed to the American people. If it is true that your health is your wealth, than determining a quality brand multivitamin is as important and requires as much investigation as does investing thousands in a particular stock in the stock market.

While more than half of adults take a daily multivitamin, even less are careful in taking a vitamin that is accomplishing the benefits the consumer desires. Consumers need to understand that they cannot just take any multivitamin and expect it to provide their bodies with the nutrition it needs, but instead consumers need to find the appropriate high-quality vitamin to support their unique health needs.

Why is it important to take a quality vitamin? Not only does a poor quality vitamin provide no benefit at all, but it may harm the consumer. Low-quality vitamins typically include preservatives and other chemical agents that can wreak havoc on one’s health.

The American College of Healthcare Sciences published an article in late 2014 listing some of the dangerous ingredients included in poor-quality vitamins warning consumers that these ingredients have been linked to increased risks for cancer and other common diseases. Consumers are largely unaware of these dangerous additives allowing these large companies to continue to profit from consumer-ignorance.

The solution to finding quality multivitamins is simple. Consumers should do their research. Reading and researching ingredients from reputable sites, like pubmed.com, will help consumers to avoid buying poor-quality vitamins. Furthermore, buyers should look for vitamins that are non-gmo and made in the USA. Vitamins made in the USA undergo stricter regulation than those made overseas in countries like China. Therefore, buyers can have more confidence that they are receiving quality with American-made supplements.

There are a few vitamin makers that have raised the bar for what constitutes for quality supplements. NOD Supplements, an American-based company, has gained increased notoriety for the high-quality supplements it offers. It has a multivitamin for men and women. Power Core Advanced Multivitamin is their most widely known product.  It provides complete nutrition.  This multivitamin is great for both professional body builders and the average person interested in improving overall health.

Overall, the vitamin consumer interested in supplementing their diets with multivitamin intake should beware that not all vitamins are created equal.  Choosing a high-quality multivitamin is important in protecting the health of its consumer. Consumers should do their research and avoid supplements that are going to do more harm than good.

Recently, the health benefits of taking Omega 3 supplements have been embraced by the American consumer. Several brands like MegaRed Krill Oil have gained popularity while promising its consumers a plethora of health benefits.   After using MegaRed for years and not seeing the results I desired, I tried a new product made by an American-based company, NOD Supplements. It’s Mega Omega 1000MG proved to be a competitive choice for Omega 3 supplements.

First, NOD Supplements is not your average supplement-maker. The company has gone above and beyond to ensure quality products. In addition to having its products manufactured locally in an FDA registered facility, NOD supplements’ products are also certified by NSF international. This certification ensures that the product has the quality and strength that appears on its label, unlike other popular brands. Therefore, when trying Mega Omega, I had peace of mind that the product I was consuming had the quality and strength that was listed on the label.

Like most products from NOD supplements, the Mega Omega is made with non-GMO ingredients.  Instead of just providing fish oil it is uniquely made with a combination of EPA and DHA that is proven to provide protection and support healthy brain and heart functions.  While on the supplement, I experienced a reduction in my total cholesterol levels and lower blood pressure after a few months of taking the supplements.

MegaOmega’s purity and quality is among the best on the market today and has been shown to provide exceptional results. It is an excellent choice for consumers that are conscience about the quality of the supplements that they take as part of a complete nutrition plan.

A Complete Primer on the Benefits of BCAAs

A Complete Primer on the Benefits of BCAAs

Amber Larsen

When I first began to explore supplementation, someone told me I needed to take branched-chain amino acids. I remember thinking, “What the hell are branched-chain amino acids good for?”

My initial concern was ingesting something I didn’t need, followed quickly by wasting money on it. Clearly, extra research was needed on my part. And come to find out, branched-chained amino acids (BCAAs) are pretty important!

So, in order to help you out and pass along what I’ve learned, this article will cover what exactly BCAAs are and why you should consider supplementing with them.

The Science of Amino Acids

We will start at the beginning with the amino acids. Amino acids are the building blocks of proteins. They get their name because they are organic acids that contain an amine group, written chemically as –NH2. Each amino acid contains a carboxyl group, a hydrogen atom, and a side chain designated by the symbol R attached to the same carbon atom. There are twenty different types of amino acids.

Bonding is important to amino acids as the side chain can consist of various chemical structures, and the differences in those side chains make each amino acid unique. There are four types of bonds:

Peptide bond – a covalent bond (sharing of electron pairs by atoms) that binds two amino acids together.

Dipeptide bond – the prefix “di” means two, so this indicates two amino acids bound together by a peptide bond.

Tripeptide bond – since “tri” means three, this is three amino acids bound together by a peptide bond.

Polypeptide bond – the prefix “poly” means many, so this is many amino acids bound together by peptide bonds.

Branched-Chain Amino Acids

BCAAs are classified separately from other amino acids. The three amino acids in this category are leucine, isoleucine, and valine. They are the major amino acids that are oxidized or broken down in skeletal tissue during ATP production.

“BCAA levels can increase the availability of carbohydrates and help protect the muscles from exercise-induced protein breakdown.”

These amino acids can then be converted into glucose (gluconeogenesis), pyruvate, or even various intermediates to produce more ATP. Even though the output of ATP is not high in regard to energy production in the muscles (3-18%), it is another avenue for energy production that can be capitalized on.

BCAAs are unique partially because of their composition, but also because these amino acids are highly prominent in muscle tissue, and can account for around fourteen to eighteen percent of its amino acid make-up. For this reason, BCAAs are important for muscle protein synthesis.

BCAAs are metabolized differently than other amino acids, and can be oxidized in the muscles during exercise for energy. BCAA levels can increase the availability of carbohydrates and help protect the muscles from exercise-induced protein breakdown. Having BCAAs in your diet may help support optimal muscle size, strength, and performance.

BCAAs and Sustained Performance

The European Journal of Applied Physiology and Occupational Physiology studied the effects of BCAAs on marathon runners. A mixture of three BCAAs was given to subjects during a marathon and the effects on mental and physical performances were measured.

Mental performance was measured by the Stroop Color and Word Test (CWT). This type of testing is used to examine the impact of interferences on reading ability. The Stroop contains three parts:

Word page – name of colors printed in black ink

Color page – rows of Xs printed in color ink

Word-color page – words from the first page printed in the colors of the second page, but the word meanings and ink colors are mismatched

The subject is asked to look at each sheet and move down the columns, reading the words or naming the ink colors as fast as possible within a given time limit.

“The results showed that both mental and physical performance were improved by an intake of BCAAs during the event.”

The results of this study showed that mental performance was improved after the marathon as compared to before the race when a BCAA supplement was consumed during the race. In the placebo group, the CWT scores were similar before and after.

The running performance in the marathon was improved for the slower runners when BCAAs were taken during the race, but there was no significant effect on the performance of the faster runners (this may have to do with adaptation). The results showed that both mental and physical performance were improved by an intake of BCAAs during the event.

BCAAs and Exercise-Induced Muscle Damage Reduction

The Journal of International Society of Sports Nutrition aimed to examine the effects of BCAA supplementation on markers of muscle damage elicited via a sport-specific bout of damaging exercise in trained volunteers.

“It seems likely that BCAAs improve protein synthesis, and thereby improve the extent of secondary muscle damage associated with strenuous resistance exercise.”

Twelve males (mean age 23 ± two years) were randomly assigned to a supplement or placebo. The damaging exercise consisted of 100 consecutive drop-jumps. Creatine kinase (CK), maximal voluntary contraction (MVC), muscle soreness (DOMS), vertical jump (VJ), thigh circumference (TC), and calf circumference (CC) were measured as markers of muscle damage. All variables were measured immediately before the damaging exercise and at 24, 48, 72, and 96 hours post exercise. The results showed:

There were significant group effects showing a reduction in creatine kinase flowing out of the muscles. Elevated CK levels are a sign of inflammation and skeletal muscle breakdown.

There was also a reduction in muscle soreness in the BCAA group compared to the placebo group.

The recovery of maximal voluntary contraction (the greatest amount of tension a muscle can generate and hold in muscle testing) was greater in the BCAA group.

The vertical jump, thigh circumference, and calf circumference were not different between the two groups.

It can be inferred from the study that BCAAs administered before and after damaging resistance exercise reduce indicators of muscle damage and accelerate recovery in resistance-trained males. It seems likely that BCAAs improve protein synthesis, and thereby improve the extent of secondary muscle damage associated with strenuous resistance exercise. BCAAs decreased reductions in muscle function, reduced soreness, and decreased the plasma levels of intramuscular enzymes, such as creatine kinase.

Conclusion on BCAAs

BCAAs are important to muscle function in more ways than one. Most people ingest BCAAs as recovery aid, but taking them before you exercise can slow down the rate at which your muscles fatigue. They can also help prevent muscle damage as well as muscle soreness. All those are plenty enough reasons to ingest BCAAs for me.

In the wide world of supplementation, I believe that BCAAs are a smart buy, either by themselves or incorporated into a broader supplement. Plain, unflavored BCAAs usually have a nasty taste to them, so I recommend purchasing a flavored version that appeals to you.
