As long as you’re doing the right things, supplements can give a boost to the benefits you receive. But how do you differentiate between the useful and the useless?

 

I’m going to be reviewing the following popular supplements based on evidence that they do what they say they do:

  • Protein
  • Creatine
  • Fish Oils
  • Pre-workouts
  • BCAA’s
  • Caffeine
  • Fat burners

Protein

Protein

This is the big one, and one of the most popular. Protein, to me, is more of a meal replacement than an actual supplement. It just simply provides more protein if you’re having trouble reaching your goals.

The most successful strength and power athletes consume at least 1 gram of protein per pound of bodyweight. It is difficult to reach this level through food sources alone, which is where supplementation makes the most sense.

 

Protein supplementation has been shown to increase muscle growth and performance if done in accordance with training. (5) Research has also shown that it is most effective when consumed immediately before or after training. (5)

 

Bottom Line:

Take it if you’re having trouble reaching your protein goals consistently with food alone. It can help you build muscle more effectively if done with training. Just don’t have the powder instead of whole-food sources. Think of it as a supplement to what you already have.

Creatine

Creatine

The creatine-phosphate system is the first energy system to ramp up when we do an activity. It’s important for powerful bursts of energy for up to 15 seconds.

 

Creatine occurs naturally in the body and we get more from protein-rich foods. Supplementation has been shown to increase the levels of creatine in the body and thereby increase the potential for high-intensity performance. (4)

 

Creatine doesn’t lead to increased muscle growth and strength on its own. Rather, it allows one to train harder, thereby resulting in bigger gains. There are also studies that show creatine supplementation plays a role in injury prevention, enhancing rehabilitation, and tolerating heavy loads. (4)

 

However, some people don’t respond as well to creatine as others. These people are referred to as “non-responders”. It’s best just to give it a shot and see what it can do for you.

 

It is also typical to have a loading phase in which you take large amounts up front to store large amounts in your body. This is largely unnecessary and can cause gastrointestinal discomfort. (4) It’s just as effective to take 1 scoop per day shortly after or before training.

 

Bottom Line:

It can help you train harder at higher intensities, thereby receiving bigger gains. Some respond better to it than others. If you’re not taxing the creatine-phosphate system (by training at high-intensities), then it’s not worth it for you. Creatine-monohydrate seems to be the form in which it’s best absorbed.

Fish Oil

Fish Oil

Fish oils contain some of the healthiest fats around, Omega-3s. But eating fish often doesn’t provide enough to meet your needs.

 

These omega-3s help prevent arthritis, psychological disorders, gastrointestinal problems, and cardiovascular disease. (8)

 

Thus many recommend taking fish oil supplements in order to get roughly 3000 milligrams daily.

 

Bottom Line:

This is the closest you’ll get to a slam-dunk in terms of benefits. Nearly anyone can benefit from supplementation, but like anything, check your current levels of intake and adjust appropriately.

Pre-workouts

Pre-workout

There seems to be a million different pre-workouts out in the market, each with a different blend of ingredients. They all aim to get you pumped up for your workout in order to train harder and reap bigger benefits. (In a similar way that creatine does)

 

Pre-workouts tend to contain blends of caffeine, creatine, beta-alanine, and nitric oxide, all of which augment performance at least initially. (3) Long-term results are not clear, as certain substances give a dulled effect when taken consistently, such as caffeine. (3)

 

They do appear to be safe although there have been many inaccuracies found with the exact amounts of ingredients in certain blends. Athletes are often wary of taking them for fear of ingesting banned substances not labeled.

 

Bottom Line:

It generally can help in the short term, mostly by augmenting your ability to workout harder. Choose trusted brands that accurately disclose what’s in them.

BCAA’s

BCAA

Branched Chain Amino Acids (BCAAs) refers to three amino acids: leucine, isoleucine, and valine.

BCAA’s promote protein synthesis and muscle growth over time. (6) They are important to have on a daily basis, but we generally already get enough of them from protein-rich foods. Supplementation is therefore unnecessary for people that ingest enough protein.

 

There is insufficient evidence to support the notion that it’s worth taking before, during, or after a workout to assist in decreasing muscle breakdown and increasing muscle growth. (6) (which is often what it’s taken for)

 

Some report a stimulatory effect with BCAA’s but without research, a placebo effect is a likely cause. (6)

 

Bottom Line:

If you eat complete protein sources, you don’t need BCAA’s in any way. Even if you are deficient, you’re better off just eating more whole-food protein.

Caffeine

Coffee

Caffeine is a stimulant, thereby increasing metabolism and energy output. It has been shown to increase maximal strength, power, and endurance during exercise. (1) It also increases mental alertness and wakefulness. (1)

 

As a stimulant, it increases blood pressure, so those with high blood pressure should stay away. (1)

In many studies, the caffeine was taken in the form of a pill or capsule, but drinking it in coffee has been shown to have similar effects, depending on the dosage. (1)

 

However, habitual caffeine consumption increases tolerance to it, thereby decreasing its effects. (7) Breaks from caffeine can bring your tolerance back down again.

 

Bottom Line:

 

It can definitely increase performance in many ways. Having it too often will make it less effective and those with high blood pressure should be wary of taking it.

Fat Burners

Fat burners

Weight loss pills and “fat burners” tend to work by doing one of a few things (2):

  1. Reduce appetite
  2. Reduce absorption of fat
  3. Increase fat burning

I’m going to review the top 3 ingredients that claim to do just this.

 

Garcinia Cambogia

 

Originally popularized on the Dr. Oz show, this ingredient supposedly inhibits a fat producing enzyme, thereby decreasing fat storage.

But there is insufficient evidence to show that it actually does anything. Some studies have shown modest weight loss, but most effects are so small that you wouldn’t even notice. (2)

 

Hydroxycut

 

It contains a handful of ingredients aimed at weight-loss including caffeine and plant extracts, but there are barely any studies on Hydroxycut's effectiveness. (2) So as of now, until more research is done, no conclusions can be made.

 

Caffeine

 

Here it is again. Caffeine is one of the most popular fat burners out there because of its stimulating properties discussed prior. While it can boost metabolism in the short term, you can develop a tolerance where it loses its effectiveness. (2)

 

Bottom Line:

 

Nobody has found a pill that can do what exercise and healthy eating can. If fat loss is your goal, stick to the tried and true methods.

 

To sum up:

  • Protein and creatine can support healthy muscle and strength development
  • Fish oil is beneficial for nearly everyone
  • Pre-workouts and caffeine can give you a little boost in your workouts
  • BCAA’s and fat burners are largely unproven so far

One important point to finish on is that a healthy lifestyle consisting of exercise and proper eating is the number 1 priority. Supplements can give you a boost here and there, but they are by no means necessary, especially for the average person.

 

To your good health,
