Defined as extreme tiredness resulting from mental or physical exertion or illness, fatigue affects everyone at some point in their life. For those with stressful schedules, demanding home and work schedules, and long lists of daily responsibilities, fatigue is a common occurrence.

The negative effects of fatigue – decreased cognitive (mental) performance, nodding off or “microsleeps,” and the associated safety hazards of these happening while you are driving, working, or performing otherwise dangerous tasks – are usually minimized, but can have serious consequences. It doesn’t take much of an internet search to find news articles about people who have lost their lives at the wheel of a car, fallen from a great heigh to their death, left appliances like toasters on at home only to find a fire when they returned, and a long list of other tragedies to know that the negative consequences of fatigue can be very serious.

Workplace fatigue is a hot topic that was taken up by the National Safety Counsel and reported in 2017. According to the National Safety Counsel, fatigue “describes the feelings of tiredness, sleepiness, reduced energy and increased effort needed to perform tasks at a desired level.” They surveyed Americans and found that 97% of Americans had at least one risk factor for workplace fatigue. Risk factors included non-day shift work, high-risk work hours, demanding jobs, long shifts, long weeks, sleep loss, no rest breaks, quick shift returns, and long commutes. Usually the first (and only) early sign is what are called “microsleeps” – also known as “nodding off.”

4. Pооr Dіеt – In tоdау’ѕ society, thеrе іѕ a fаѕt food rеѕtаurаnt on every соrnеr. Wе аrе bombarded wіth ads, commercials аnd саmраіgnѕ fоr hіgh fat, hіgh ѕugаr, рrосеѕѕеd foods.

Additionally, with the іnсrеаѕеd hype about lоѕіng wеіght, dieting fads саll fоr restrictions оn саlоrіеѕ, оr ѕресіfіс food grоuрѕ, аnd ѕоmе реорlе even fееl the nееd tо abstain altogether.

This is by no means a complete list, but hits all of the common causes. In almost every case, a person’s feeling of fatigue will have *multiple* causes and addressing all of them will help the most. However, occasionally there is a specific medical condition (like sleep apnea) that contributes to the sense of fatigue. In any case, fatigue is a serious condition that most of us deal with – and adults have found many ways to deal with the symptoms without addressing the underlying causes. Energy pills, drinks, powders, and syrups are very common – and while they are fantastic short term remedies, they do not address the underlying cause. The best approach is to find and fix the underlying cause if you can and use short term remedies only as needed.



Dr. Nick has been practicing medicine for over 10 years. After finishing his MD he began his residency in Laboratory Medicine where he gained first hand knowledge of some of the effects of dietary supplements. Dr. Nick now specializes in gastrointestinal health, Over the years of vigorous study and in-depth experimenting with a variety of dietary supplements Dr. Nick found that there are few sources of clear, evidence-backed, honest information about what the supplements can help achieve - and what they cannot. There are many companies out there selling promises without providing results.

Dr. Nick's goal is to educate the general public and do his part to help the world get healthy again. The industry needed an honest educated practitioner to reveal the real benefits of specific dietary supplements and to unbiasedly dig into the formulas and companies selling these formulas to reveal the true Pros and Cons of each supplement and to educate the general public about these ingredients found in various dietary supplements. Dr. Nick promoting general health and proper use of nutritional supplements is step one of the goal. In order to get the best effects without wasting time and money, a proper understanding of chemistry and human physiology are critically important. Since not everyone has the time to master these topics, Dr. Nick hopes to help clarify otherwise complicated topics and give the best, clear, evidence-backed input to help each person select the most appropriate supplements.
