Workout Supplements You Should Pack In Your Gym Bag

What you put into your body is just as important as how much or how often you exercise. Unfortunately, what you put into your body can also deter you from reaching your ultimate workout goal. When it comes to supplements, theres the good, the bad, and the useless. Before considering which supplements are best for you, remember this: You do not NEED any workout supplement. All essential muscle-building and weight loss ingredients can be found at the grocery store. However, for people without a large appetite or an appetite for unhealthy food, certain workout supplements can make up for the vitamins and nutrients they are not getting from food. Lets take a look at what supplements we should and shouldnt use:

Ways To Reduce Side Effects

Caffeine dosing is very individualized, as some people tolerate it better than others.

The best way to reduce side effects is to start with a small dose of a caffeinated pre-workout supplement, slowly increasing your dosage to see what you can tolerate.

Remember that its best to avoid caffeine for at least 6 hours before bed to help prevent sleeplessness .

Of course, you can also choose pre-workout supplements without any caffeine.

Summary Youll find caffeine in most pre-workout supplements, but this stimulant can cause jitteriness, anxiety, and an increased heart rate. If you experience side effects, try a smaller dose to see how your body reacts.

Creatine And Fear Mongering

Damage From High Blood Pressure Stock Vector

While a great rule of thumb, If its too good to be true, it usually is sometimes gets misused by people trying to take down whatever appears to be great just to appear controversial.

Personally, I feel there are many valid reasons to say that creatine isnt perfect. Creatine non-response, or how some people simply do not get the claimed benefits of creatine due to how their body is, is a great example.

Varying response rates explain why some people gain easily over five or more pounds of muscle while using creatine while others are lucky to gain one pound over a year. Reliability in beneficial effects yet unreliability in magnitude isnt the best feeling to us nonresponders.

However, rather than this valid example creatine was linked to kidney damage seemingly because it had to have something wrong with it and kidney concerns are an easy go-to among worrywarts.

But claims stated without evidence can be dismissed without evidence, which makes it a bit of a predicament when a good chunk of this fear mongering came out of a misinterpretation of actual evidence.

Expert: Take Alarm Bells With Grain Of Salt

Sports nutrition pioneer Susan Kleiner, PhD, did some of her early research on bodybuilders. She has decades of experience guiding strength and endurance athletes as a clinical nutritionist and principal in the firm High Performance Nutrition LLC. She said the new review paper provides a good overview of practices followed by some, but by no means all bodybuilders. And she said the authors conclusions shouldnt be taken to cast aspersions on the use of supplements in general.

Fro one thing, the data set is not very large, Kleiner noted. And she said that the authors acknowledged that most of the studies did not measure kidney function in a way that gives the best picture of renal health individuals with far more muscle mass than the average individual, something that practitioners should take note of.

And, she said while the high protein intakes look eye-popping to some, theyre not inherently dangerous.

High protein diets, and creatine supplementation according to dosing recommendations do not cause disruption to kidney health, Kleiner said.

People with compromised kidney function should generally not eat a high protein diet, but dialysis may reduce intrinsic creatine production and creatine supplementation may be indicated, she added.

Tingly Or Prickly Sensations

A common side effect of many pre-workout supplements is a tingly or prickly sensation throughout your body. Everyone is different and it depends on your sensitivity to certain ingredients found in the pre-workout supplements. While a side effect it really isnt anything to be worried about.

If the pre-workout supplements contain ingredients such as niacin, beta-alanine, or vitamin B3, youre more than likely going to get this sensation.

Many pre-workout supplements include niacin in a higher dose just for that very reason. They want you to feel something after taking their pre-workout supplements. It comes back to people equate something working if they can feel them. High dosages of niacin can also cause a flushing effect on the skin where it can become red, blotchy, and even itchy as if you have hives .

Alternatives And Ways To Reduce Side Effects

People can reduce the potential side effects of pre-workouts by following the recommended dosage on the product label or packaging.

Research into consumer habits around pre-workout supplements found that 14% of people reported consuming two or more doses, while 18% of individuals consumed them more than once a day. To reduce some side effects, people can either lower the dose or split the dose into several smaller amounts.

If a person is experiencing digestive issues when starting a pre-workout, they may wish to find a product that does not include potential triggers, such as caffeine and sodium bicarbonate. They could also try lowering the dosage.

To avoid potential sleep problems, a person can take pre-workouts, including caffeine earlier in the day, to ensure the stimulant has worn off before going to bed.

If an individual wants to avoid pre-workouts altogether, they can find common ingredients, including creatine and beta-alanine, in foods such as red meat, fish, and poultry. A person may also improve their workout without pre-workout supplements by focusing on their diet before and after exercising. Health experts suggest:

  • eating a meal within 2 hours of a workout
  • eating snacks beforehand that include complex carbohydrates and protein
  • staying hydrated before and throughout a workout
  • eating a balanced meal after a workout, preferably including protein

What Causes Rhabdomyolysis

How do your kidneys work? – Emma Bryce

Rhabdomyolysis can happen for many reasons. Garay experienced exertional rhabdomyolysis, meaning he pushed himself extremely hardto a point of muscle exhaustion and damage. The condition can also develop from trauma cocaine, amphetamine, antipsychotic, statin, or cholesterol medicine use or electric shock, says Dr. Wang.

Dehydration and high temps while you work out can increase your risk, says D. Alan Nelson, Ph.D., MPAS, who studies the condition at Stanford University School of Medicine.

Obesity, tobacco use, muscle enzyme deficiency and, a recent study found, sickle cell trait, can all increase your chances of developing rhabdomyolysis. Men are also more likely to get the condition than women.

For exertional rhabdomyolysis, think of activities that engage the large muscle groups to an extreme degree, like long, hard and fast runs, Crossfit, rucksack marching, football practice, triathlons, marathons, says Nelson. Its really strenuous acts, for a duration you wouldnt normally do.

And take note if youre into indoor cycling: Researchers recently reported an uptick in rhabdomyolysis after spinning workouts, and the risk may be especially high after your very first spin class.

Interestingly, Nelson says, fitness level does not impact the chances of someone getting rhabdomyolysis. So, whether youre new to a workout or youve done it hundreds of times, its about the level of exertion.

Can I Use Coffee As A Pre

As we’ve mentioned, coffee and pre-workout share a common primary ingredient caffeine. Found to have an effect on improving athletic performance, coffee also doesn’t contain the additives and additional ingredients that other pre-workout supplements may have. Studies have shown that caffeine concentration peaks at about 45 minutes after ingestion, with effects lessening thereafter.

Simply put yes, you can use coffee as a pre-workout.

Protein Including Whey Protein

The most widely used pre-workout supplement used is protein, in the form of powders, bars and other mediums. Proteins are one of the main components in muscle building, and at first glance, one would think that isolated proteins, such as whey, are a healthy way to increase muscle mass.

Taken correctly and in small doses, this does hold true but if too much protein isolate is ingested, it can be harmful for your kidneys in the long run.

Whey protein is safe when taken as a single dose of up to 50 grams, or when 30 grams is taken daily for six months. Its recommended to take regular breaks from consuming whey protein, and to not take it daily for more than six months at a time. Indeed, you should only be consuming whey protein on weightlifting days, immediately after your workout, to see results and minimize negative health risks.

According to Mayo Clinic, whey protein may cause also abnormal heart rhythms, changes in cholesterol levels, headache, increased diabetes risk, increased fracture or osteoporosis risk, kidney dysfunction, liver damage, stomach or intestine symptoms , and thirst. Eep.

In addition, whey protein may lower blood sugar levels, and is not advisable for people with diabetes. A healthier alternative to protein powders and whey protein are protein-rich eggs. Adding them to your pre-workout supplement milkshake will give you great results, without all the harmful side effects.

Preventing The Side Effect

What you might do to counter the effects of taking a pre-workout supplement late at night

Everyone metabolise caffeine at different rates, so in this instance, you might be able to get away with using your pre-workout supplements as late as 8 pm. However, if you metabolise it extremely slowly, you might still be feeling the effects of the stimulant from a lunchtime workout. You could also lower the dose/serving size of your pre-workout supplements so the effects arent as drastic as a full serving, which could allow it to exit your system faster.

Whole Food Alternatives To Pre

Regardless of whether you choose to use a pre-workout supplement, fueling for exercise is incredibly important and can make a big difference in how you feel and perform in your training session .

The International Society of Sports Nutrition has found that consuming carbs and protein before and after exercise can improve both strength and body composition .

Think ahead to your workout so that you can plan a balanced meal containing carbs, protein, and fat about 23 hours beforehand. For example, try a veggie omelet and whole wheat toast with avocado spread, plus a side of fresh fruit.

If time gets away from you, try an easily digestible source of carbs like a piece of fruit about 3060 minutes before your workout.

If you skip the pre-workout supplement but still want the performance-boosting effects found in caffeine, drink a cup of coffee alongside a pre-workout snack.


Pre-workout supplements cant replace a balanced diet, good quality sleep, and adequate hydration. If you prefer to use one anyway, be conscientious about its ingredients and your total intake.

Pre-workout supplements are primarily used to enhance physical performance and energy levels, but research doesnt back many of their supposed benefits.

Most pre-workouts are considered safe for healthy adults, but they arent essential for health or performance (

Artificial Sweeteners And Sugar Alcohols

Pre-workout supplements frequently contain artificial sweeteners or sugar alcohols.

While these ingredients enhance flavor without adding calories, some sweeteners may cause intestinal distress and discomfort.

In particular, a high intake of sugar alcohols may trigger uncomfortable symptoms like gas, bloating, and diarrhea all of which can disrupt your workout .

Some people report a similar digestive response from eating certain artificial sweeteners like sucralose. However, such symptoms havent been scientifically proven .

You may want to avoid pre-workout formulas that contain large quantities of these sweeteners. Otherwise, try a small amount first to see how you tolerate it.

Amino Acids And Vitamins

Energy Drinks & Pre-Workouts WATCH OUT Kidney Stones!

There are a number of common amino acids and vitamins that have found their way into pre-workout regimens. The amino acid beta alanine can help reduce that painful burn in your muscles during exercise. Studies suggest it reduces fatigue and improves performance. Its main side effect is a tingling sensation in your hands and feet. Niacin, also known as Vitamin B3, is popular for its metabolizing effects. Since most people get enough through their diet, its generally unnecessary. Once a popular pre-workout supplement, branched-chain amino acids are fairly safe but damaging to your wallettheres little evidence they work. On the other hand, the amino acid taurine improves metabolism.

Some athletes enjoy a protein-laden, pre-workout smoothie. While most nutritionists insist that even the physically fit get enough protein in their diet, fitness fanatics insist on that protein shake. The truth is, too much of just about anything can have negative consequences. The best way to know what you are putting into your body is to read the labels. If you are uncertain, dont buy it.

This can cause problems in the kidneys, as this molecule is large and difficult to pass through the bodys filtration system, says Gordon Wang, M.D., a family medicine physician in Punta Gorda, Florida. This muscle damage and tissue breakdown can lead to kidney damage or failure if left untreated.

Creatine And Kidney Biomarkers

Diabetic Nephropathy

The biomarker issue, which is more relevant, pertains to creatinine as a metabolite. Note the extra -ine at the end of that word, its important.

Creatine, when metabolized in the body, will turn into creatinine.

Creatinine is whats eliminated from the body. As creatine is a vital molecule that always exists in the body then its metabolite, creatinine, will always be present in your blood as well.

Creatinine, in particular, is fairly sensitive to kidney issuesinsofar that when the kidneys are damaged then a lot more creatinine is reabsorbed into the body than rightfully eliminated. When they kidneys are damaged, blood creatinine levels tend to be increased.

This is why you have creatinine measured when you visit the doctorsits a biomarker for kidney health. Biomarkers are cheap, efficient, and seemingly reliable ways to determine problems that dont require more expensive and invasive investigation.

Each biomarker differs and has its own upsides and downsides. Creatinine is pretty reliable under most conditions for indicating kidney damage, with only one exception.

If you consume more creatine than normally expected, more of its metabolite will be produced. This causes a small elevation of blood creatinine levels that, without context, looks indicative of kidney damage at first glance.

Alas, it is a false positive.

However, rest assured, that scientifically speaking all the above are non issues.
