The Best And Worst Workout Supplements
From supplements that help pack on the muscle to options that help avoid "muscle wasting" and provide energy for longer workouts, these are some of the most popular options on the market. Some supplements have been vetted through clinical studies while others are simply favorites of many weight lifters, aerobic fanatics, and other workout regulars.
Whenever possible, we included research studies compiled by the National Institue of Health and information provided directly from the NIH. As always, we suggest consulting with your doctor or a dietician before you start taking any type of potentially performance-enhancing product.
TRY: Whey Protein Offers Numerous Benefits
One of the most popular choices among people who love hitting the gym is whey protein. It's easy to see why this supplement is important for many people looking to pack on the muscle. Whey protein helps build muscle and aids in muscle recovery after an especially hard workout.
Whey protein also helps with amino acid development which starts to deplete with age and some illnesses. Whey protein helps deliver oxygen and nutrients to your muscles and it can help curb hunger. The National Institute of Health says protein "optimizes muscle training response during exercise and subsequent recovery period."
TRY: Glutamine
If you're eating beef, chicken, eggs, veggies, and other foods that are part of a balanced diet you're already receiving a good dose of glutamine. However, if you're pushing hard in the gym, especially with weightlifting, you could benefit from some extra help.
Glutamine helps with muscle recovery, allowing you to get back to work faster as you increase weights. If you're at the gym every day, glutamine may be an easy choice for your routine. The National Institute of Health notes that several studies have shown it "may help with recovery of muscle strength and reduce muscle soreness after exercise."
AVOID: HMB Supplements Can Help With Lean Muscle
HMB, also known as beta-hydroxy beta-methylbutyrate, is a molecule that is found naturally in our bodies. When you have enough HMB you will notice gains in lean body mass. HMB works by improving the effects of protein and leucine in your diet.
Lean muscle mass ensures your body works to burn off calories and it aids in future muscle gains by providing you with a stronger base to work from. Leucine is the main ingredient in BCAA, the next supplement on our list. We would avoid this product and go with BCAA supplements.
TRY: BCAA Is An Amino-Acid Powerhouse
BCAA or "Branch-Chain Amino Acid" is taken before or after a workout. BCAA's three main active amino-acids include leucine, isoleucine, and valine. BCAA helps avoid "muscle wasting" by increasing muscle growth and reducing lean mass losses. The BCAA's in our body accounts for 35% of the essential amino acids in muscle proteins and 40% of all our amino acids.
BCAA's are believed to reduce and even stop muscle wasting. This supplement has also been shown to reduce exercise fatigue. The NIH notes that several studies have found the "possibility of greater gains in muscle mass and strength during training."
TOSS-UP: Nitric Oxide Boosters Supplements
Nitric Oxide booster supplements can provide more energy during a workout and also aid in muscle recovery following the end of your routine. As the name suggests, these supplements deliver more oxygen to your muscles by improving blood flow. With a better delivery system, your muscles receive more nutrients, anabolic hormones, and water.
This supplement is actually a compound found naturally in our bodies. The product causes blood vessels to widen and stimulates the release of certain hormones including insulin and human growth hormone. The National Institute Of Health notes that "while some reported that dietary supplementation with NO donors induced benefits in exercise performance, others did not find any positive effect."
TRY: Creatine For Maxed Out Repititions
Creatine is found naturally in muscle cells. It is partially responsible for allowing muscles to produce energy, especially if you're workout regime includes heavy lifting and high-intensity exercises. Creatine is actually produced from the amino acids glycine and arginine.
You gain additional creatine from meat intake and exercise along with muscle mass and hormone levels such as testosterone. 95% of creatine is stored in muscles as phosphocreatine. When we increase these levels we develop more energy in our cells in the form of ATP, the body's high-energy molecule. The National Institute of Health notes that creatine may "increase strength, power, and work from maximal effort muscle contractions."
TOSS-UP: ZMA Could Help With Certain Deficiencies
ZMA is a combination of ingredients: zinc, magnesium, and vitamin B6. All three of these ingredients are essential for people who push their bodies in the gym. Be aware that the jury is still out on this supplement in terms of improving energy in the gym, a claim made by some manufacturers.
With that said, if you're low on zinc, magnesium and vitamin B6 on your diet, this supplement may help improve your blood sugar control and mood. The active ingredients are also believed to help improve immunity. Honestly, improving your diet may be a better option. Studies are still lacking but many popular fitness publications swear by the product.
TOSS-UP: Vitamin C
Studies into the effects of Vitamin C on the body during workouts have pointed to better muscle recovery and growth. Researchers have also found that this supplement helps with overall energy levels which could improve your time spent in the gym.
Many bodybuilders swear by Vitamin C because it helps with protein metabolism and blocks the synthesis of vital proteins that can lead to infection and inflammation. It is also believed to help lower the ratio of cortisol to testosterone, allowing for better gym performance in males. The National Institute of Health notes that studies have yet to find a direct increase in performance in people who take vitamin C supplements as part of their workout routine.
TRY: Casein Is Often Used As A Bedtime Supplement
Casein is a dairy protein that is found in milk. It is often taken before bed because it's a slow-digesting product. Casein releases amino acids at a slow rate, allowing for muscle recovering both throughout the day or during our sleeping hours.
Several studies have shown the benefits of taking Casein. It is often taken right before bed because that's when much of our actual muscle growth cycle occurs. If you're looking for big gains with round-the-clock assistance you might want to look into taking Casein as part of your daily routine. The National Institute of Health posted several studies that seemed to show both Casein and standard Whey Protein working towards the same gains and fat-loss.
Toss-Up: Fish Oil For Inflammation
Fish oil is an amazing product even without weightlifting. The supplement helps promote heart, brain, eye, and joint health. Bodybuilders and intermediate gymgoers love it for what they believe is the product's anti-inflammatory benefits. While not as highly researched for bodybuilding, athletes swear it helps promote muscle growth while also providing a better range of motion.
The U.S. Department of Agriculture (USDA) says we should eat 8 ounces of fish per week and if you're not doing that this might be a smart supplement to consider with your doctor's approval. Also, eat more fish!
AVOID: Greens Supplements
If you're not eating enough veggies, algae-based foods, grasses, and fruits, you might want to consider a "greens" supplement. This product takes various nutrient-rich foods like wheatgrass, alfalfa, herbs, vegetables, legumes, and fruits, and compacts and distills them into powdered form.
We always recommend eating a balanced diet that includes healthy food options but this is a good stepping stone to realizing what a nutrient-rich diet can do for your energy levels and your ability to spend more time in the gym. We marked this supplement as "avoid" because it's incredibly easy to achieve proper levels with whole foods.
TOSS-UP: Vitamin D Has Many Positive Effects On Your Body
Vitamin D, while not exactly a "workout supplement" has many positive effects that may help in the gym. This is especially true if you live in an area where the winter months steal too much of your typical exposure to sunlight.
Vitamin D helps with testosterone output, improves bone density, and has been shown to increase energy levels, all good things for the gym. Several health bodies in the UK have recently suggested this supplement in areas where the sun is lacking for much of the year. The National Institute of Health notes that Vitamin D can help people who have "difficulty exercising" but the comment doesn't point specifically to studies focused on Vitamin D and exercise performance.
TOSS-UP: Iron Could Be Beneficial In Certain People
The National Institute of Health notes that Iron is a supplement that might help exercise performance specifically in people with anemia. In these individuals increasing iron to an acceptable level has been shown to improve exercise performance in some groups.
Iron helps increase oxygen updates and reduces heart rate. Iron also helps decrease lactate concentrations during exercise. If your iron levels are within a normal range we suggest skipping this supplement altogether.
TRY: Sodium Bicorbonate May Provide Short-Term Help
Sodium bicarbonate is known to enhance our body's disposable of hydrogen ions which are created with intense muscle activity. In completing its task, the product reduces metabolic acidosis and the muscle fatigue that results from that process.
Several studies have shown minor to moderate improvement in performance for both short-term and intermittent high-intensity activity. If you're reaching athlete-type levels this product is probably more beneficial than users who only casually workout. The National Institute of Health notes that this supplement "Might provide minor to moderate performance benefit for short-term and intermittent high-intensity activity, especially in trained athletes."
TOSS-UP: Tart Or Sour Cherry
Tart or sour cherry features phytochemicals that are believed to "facilitate exercise recovery by reducing pain and inflammation," according to the National Institute of Health. However, there have only been several studies conducted and the results have been mixed.
It's believed this product can aide in muscle strength recovery while reducing soreness after a workout. It may also reduce inflammatory effects on our lungs, although the jury is still out on the product's ability to improve aerobic performance.
