Should You be Taking Supplements?

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.


​Probably the most confusing aspect of the health and fitness industry is the world of supplements. There are thousands of different nutritional supplements out there, and your mom, dad, sister, neighbor and friend are probably all taking various types.

The topic of supplements is incredibly controversial: you’ll have one person that has a bunch of packets, pills and oils lined up on their counter, arguing that they are absolutely necessary to feel completely healthy and thriving. On the flipside, you’ll have someone who won’t ever touch a single supplement because they think they’re all a sham and a money-making scheme.

Where do you fall? If I had to guess, probably in the confused but willing to dabble category.

In this article, I will teach you the difference between essential nutrients and non-essential nutrients, common supplements that have been researched thoroughly and have very well-known effects, and the benefits of taking or not taking certain supplements. You should be able to determine whether or not you NEED to be taking a supplement.

​So, the next time your neighbor brings over her catalog of pill bottles, you’ll know whether or not to say “thanks, but no thanks”.

Essential vs. Non-essential nutrients

Nutrients are what our body uses for various physiological functions. Many nutrients are necessary for normal functioning and without them we would cease to function properly. Some of these nutrients our body can make itself, while others we have to get from food. Essential nutrients are those nutrients found in food that our body MUST have. They’re essential (duh!). Essential nutrients include proteins, essential fatty acids, vitamins and minerals. Some plant based nutrients (called phytochemicals or phytonutrients) may also be considered essential as they play a host of important functions.

Because we can eat our essential nutrients, supplementing with these is not necessarily needed. However, someone may have a hard time meeting their protein requirements or omega-3 fatty acid requirements, so they may need to increase their intake of these nutrients through supplements. Likewise, a large part of the population is malnourished when it comes to vitamins and minerals, so taking a multivitamin/multimineral supplement may be important for many individuals. Even still, the emphasis should always be on trying to meet your nutrient needs through real, whole foods. God did not design our bodies to always need a vitamin supplement!

The non-essential nutrient category is much broader. Non-essential nutrients are nutrients that we can either make ourselves or we don’t necessarily NEED for normal functioning. Nutrients that fall into this category are caffeine, green tea extract, tyrosine and glutamine (different amino acids), creatine, some so called “fat burners”, and many other nutrients. Some of these supplements produce well-documented benefits (like caffeine and creatine), while others are less known.

What you need to know is that supplements are NOT regulated by the FDA (Food and Drug Administration), which means they do not analyze supplements for their safety, purity or effectiveness. Supplement companies are on their own and can say whatever they want about their product. In fact, they can legally package sugar in capsules and sell it as a fancy supplement, with the consumer never the wiser. With supplements, especially non-essential nutrients, you should ask yourself if the risk is worth the reward.

Common Supplements

If you’re considering taking a supplement, you need to first ask yourself if you actually need it. Do you already eat a very well-balanced diet like this yet still have some nutritional deficiencies? Do you have specific performance and body composition goals that are difficult to achieve with your ordinary diet? Do you have a dietary restriction that prevents you from eating adequate nutrients? Do you have a medical condition that would necessitate the need to supplement? Remember, supplements are just that…a supplement to your ordinary diet. Make sure your eating habits are top-notch and then supplement if absolutely necessary.

Essential Nutrient Supplements

​There are some common “essential nutrient” supplements that may be beneficial to take, especially if you feel there may be some small holes in your diet.

Protein powder is helpful as a meal replacement in smoothies when whole food protein is inaccessible.

Fish oil. Most people do not consume enough omega-3 fatty acids so taking fish oil (or other omega-3) supplements is very important. Look for one that contains at least 30% EPA and DHA and take at least 3g per day.

Greens supplement. Likewise, many fall short when it comes to eating enough produce so a greens supplement (powdered green food blend) can fill the gaps. This should be used very infrequently as it is much better to strive for eating high amounts of fruits and vegetables.

Multivitamins & multiminerals should be taken every day, unless you are extremely conscientious about eating a varied diet.

BCAAs. A branched chain amino acid drink (BCAAs) is helpful during very high intensity exercise sessions when you’re working hard to lose fat but still need enough energy to perform.

Protein-carb workout drinks are also beneficial during very high intensity workout sessions where muscle strength and size is the desired outcome.

Non-Essential Nutrient Supplements

Here are a couple common, and well-researched, “non-essential” supplements. Remember, you probably don’t NEED these if you’re eating very well and your essential nutrients are taken care of. Be very judicial about whether or not you really should be taking these.

Caffeine. Even though we don’t think of it as such, caffeine is a widely used supplement that stimulates your central nervous system. It can be beneficial to improve your focus and readiness prior to competition. Many cannot tolerate caffeine so be careful with it. Most average trainees should not need caffeine for performance.

Creatine is another very well-known supplement that can help replenish energy stores during very high intensity training. It allows you to train harder with a much greater intensity. Unless you’re training at incredibly high intensities for extended periods of time, you probably won’t benefit from creatine.

Tyrosine and phosphatidylcholine help reduce nervous system fatigue and/or symptoms of nervous system stress during periods of heavy training.

Green tea extract stimulates the metabolism during weight loss phases. Make sure the extract is high in EGCG, which is the most active component. If you’re nutrition and training is perfect, yet you’re having a hard time with fat loss, this may be helpful for you.

Similarly, CLA (conjugated linoleic acid) is a fatty acid that stimulates metabolism and can be helpful during periods of fat loss.

The list of non-essential nutrient supplements could go on and on, but those listed above are the most common and widely used. Creatine, for example, has been thoroughly researched for its safety and efficacy, however many other supplements have not. There are some supplements that may promise certain benefits, but the research done on that particular nutrient could be very limited and the true effects are unknown.

When considering whether or not to take a supplement, ask yourself if your nutrition is up to par. Could you be eating better? If the answer is yes, start there. Fix your diet and then see if you still could benefit from a supplement. I generally suggest to my clientele to just take a multivitamin/mineral and fish oil supplement. For the average person looking to workout hard, shed some body fat, get healthier and feel better in general, these two supplements combined with a good nutritional plan will do the trick.

Try not to get too bogged down with this and especially don’t spend your whole paycheck on supplements! Eat well, train hard, and then fill in the gaps if you need to.
