Why Whey Protein?

Now that you have learned about the company that makes good quality whey protein, you must also be clear on what exactly whey protein is and how it can help you. Let’s start with all the benefits:

  • Whey Protein is one of the richest sources of branched chain amino acids or BCAAwhich the body requires urgently during and after heavy exercise. An active lifestyle without sufficient BCAA supplements can lead to fatigue and wear and tear across the body. Whey protein is a great way to avoid these issues in a dependable and delicious manner.
  • But it’s not good just for exercising individuals. In 2009, a study done at McMaster University in Ontario, Canada observed that whey protein, when consumed by individuals at rest, helped in the repair and growth of muscles almost 9 times greater than casein and soy – other popular types of protein.
  • Whey protein is also a great way to lose weight. It is used by dieters across the world to aid their weight loss program. This is mainly because it has little fat and carbohydrates and can help increase the metabolic rate of the body when combined with exercise.
  • In some preclinical studies performed on rodents, it was observed that whey protein also has anti-inflammatory properties similar to certain prescription medicines. Some other studies have also indicated that whey protein may possess anti-cancer properties but further research is necessary to establish it as a fact.
  • The British Journal of Nutrition published a study that observed a significant decrease in the total cholesterol and LDL cholesterol levels after about 12 weeks of using whey protein. The same was not observed with casein.

Possible Side Effects

Even though the lactose content in whey protein is not very high, it can still cause lactose intolerance in some highly sensitive people. Otherwise, it usually only causes side effects if consumed in excess quantity.

Some of the side effects it can cause include stomach pains, cramps, a reduced appetite, nausea, headache and fatigue. If you are experiencing any of these symptoms, reduce your intake and observe for a couple of days. If it still doesn’t help, consult a doctor or medical professional before resuming use.

Some Facts about Whey Protein

Lastly, before heading on to decide the best of all Optimum Nutrition flavors available today, let’s take a look at some interesting facts about whey protein that any health enthusiast must know.

  • It is mainly composed of Alpha-lactoglobulin, beta-lactoglobulin, bovine serum albumin and immunoglobins (IgG1, IgG2 and IgM).
  • It is also a rich source of glutamine which helps increase the absorption rate in intestines.
  • Unflavored whey protein has a taste that is commonly described using words such as brothy, sour and bitter. This is why manufacturers around the world, including Optimum Nutrition, offer various innovative flavors to consumers.
  • Whey protein is also popular for reducing hunger, especially amongst people wanting to lose weight. It reduced hunger by reducing levels of the ghrelin hormone that is responsible for telling your brain that you are hungry.

One Last Tip

Introducing whey protein in your diet is a major step in terms of the benefits it has to offer. However, as with any other nutritional supplement, it only makes sense to first consult a doctor or medical professional before starting full-fledged use.

Remember to mention any allergies you may have, especially if you suffer from lactose intolerance. Once you get the go ahead from your doctor, you can choose from 21 flavors offered by Optimum Nutrition to begin your whey protein regimen.
