Criteria Used for Evaluation
A brand is crucial when making a purchasing decision. This is due to the overall impact it will make on a company. Branding changes how individuals perceive a product, as it can also encourage new business and increase awareness.
Branding Gets Recognition
Branding is important to a business because it is how companies get recognition and become well-known to consumers. The logo is an important component of company branding, as it represents the face of the company. A professional logo should be easily memorable and powerful - with the sole purpose of making an impression at first glance.
It Increases Business Value
An established brand increases value in a business by giving a company leverage in the industry. This makes it an appealing factor when trying to generate future business.
It Generates New Customers
A strong brand represents a reputable impression of the company among consumers. They are more likely to conduct business with a brand they are most familiar with. If a brand is well-established and trustworthy, people will be more apt to spread the word.
Creates Trust With Consumers
A well-strategized branding helps a company build trust with existing customers and potential ones. The public will most likely do business with a company that gives the impression of being experts in a particular industry.
Ease of Use
Glutamine supplements can come in many forms. The one you decide to take depends on how well they absorb in your body, and your personal preference. For example, some glutamine supplements are sold in a pill or capsule. Other supplements absorb faster in liquid form.
Certain supplements are sold in pills because liquids may be ineffective for some people. Others need to take a liquid when it becomes difficult for the body to absorb a pill, or when it is difficult for them to swallow tablets or capsules.
And not all forms of glutamine are the same. For example, there are different strengths to choose from. When in doubt, consult a physician about which particular supplement suits your needs.
Take notice that supplements are not endorsed by the FDA in the same manner that drugs are. They do not review supplements for efficacy or safety before they are sold to the public. Always research when choosing new supplements. Other ways to be safe:
If your diet consist of vegetables, fruits, and whole grains, speak with a physician to see if glutamine will enhance the results you are looking for.
Glutamine can be unsafe if taken in high doses. It can also affect people diagnosed with certain diseases.
Breastfeeding or pregnant women should avoid glutamine as it can be harmful to the baby. A prenatal vitamin is sufficient until delivery.
Heart medications such as aspirin, blood thinners, diuretics and steroids may not mix well with a glutamine supplement; and may cause a medical condition to get worse.
People going for surgery should avoid glutamine, as it may cause a negative reaction.
People with certain types of cancer or who are being treated for it should avoid glutamine.
Select studies that used preparations of glutamine were linked with a few side effects. This can include but not limited to gastrointestinal symptoms, swelling of the extremities, infections, headaches, and fever.
As far as drug interactions, a few reports suggested that glutamine may reduce the ammonia-lowering effect of lactulose. For people with hepatic encephalopathy or liver cirrhosis, glutamine may not be the best choice of supplement to take.
Check for evidence from scientific studies. Search for credible publications on how well the product works. You can contact the manufacturer to ask for studies to back up their claims. Find out how they ensure their ingredient label. Make sure the same ingredients are actually in the bottle.
If a product claims to cure a disease, or is listed as “all-natural”, or has a refund guarantee, take precaution. If it sounds too good to be true, then most likely it is.
It is ideal to choose brands that are labeled with the US Pharmacopeia, Underwriters Laboratory, NSF International, or Consumer Lab seal. These companies provide a verification process that ensures that labels contain the ingredients that the label claims. They also check for purity in the ingredients.
Many supplements manufactured outside the U.S. are not regulated and may contain toxic ingredients.
Supplements do not last forever, and may need a little care to ensure their potency. Keep glutamine supplements in a cool and dry place. Avoid damp spots such as bathrooms. Keep supplements on in a locked cabinet or on a high shelf, away from the reach of children.
Some supplements lose their potency when they sit out on the shelf for too long. Do a routine check and throw out any supplements that are past their expiration date.
