Without a doubt, you can add muscle simply by eating right and lifting weights. But to truly maximize your growth potential, supplements are a requirement. Hence, we’ve compiled a rundown of the 11 best mass-gain supplements on which to spend your hard-earned cash.
These supps are listed in order of priority, from the absolute most critical, can’t-do-without supplements to the less crucial, yet still highly effective ingredients for packing on size. The point is to help those on a tight budget decide which supplements to buy. If money is no object, then by all means knock yourself out and use them all as directed. Because after all, as far as we’re concerned, you can never have too much muscle.
Why it made the list: Whey tops the list of mass-gain supplements because it’s the most crucial for pushing protein synthesis. Whey is a milk protein that has a high level of branched-chain amino acids (BCAAs, No. 4 on our list). Bottom line: Whey takes the crown because it digests fast and gets to your muscles rapidly to start building muscle. Whey also contains peptides (small proteins) that increase blood flow to the muscles. This is why we always recommend consuming whey protein immediately after training.
How to maximize its effects: Take 20 grams of whey protein powder in the 30 minutes before working out, and take 40 grams within 60 minutes after training. Also consider taking 20-40 grams of whey immediately upon waking every morning to kick-start muscle growth. Your best bet is to choose a whey powder that contains whey protein hydrolysates (whey protein broken down into smaller fragments for faster digestion) or whey protein isolate
Why it made the list: The other milk protein, casein, squeaks in just under whey. Casein has always played second fiddle due to its very slow digestion rate, yet this makes it ideal as a pre-bedtime snack because it prevents catabolism while you sleep by emptying slowly and steadily. Casein also makes you feel less full, which makes it a great snack for those who want to pack on muscle mass. And new research finds that casein gives whey a run for its money – when it’s taken postworkout, casein boosts muscle protein synthesis much like whey does. It’s even suggested that a whey and casein protein shake taken after training increases muscle growth better than either protein taken alone.
How to maximize its effects: Choose a casein protein that contains micellar casein (the slowest-digesting casein you can buy) and take 20-40 grams right before going to bed. After workouts, add 10-20 grams of casein to your whey protein. Also, use 20-40 grams of casein in your protein shakes between meals.
Why it made the list: Creatine is made from three amino acids: arginine, glycine and methionine. Anecdotal reports and scientific studies alike find that guys who take creatine gain a good 10 pounds or more of bodyweight and increase strength dramatically. Creatine works in a number of ways. For one, it increases the amount of fast energy in your muscles needed to perform reps in the gym. The more of this fast energy that’s available, the more reps you can do with a given weight, allowing you to get bigger and stronger in the long run. Creatine also draws more water into your muscle cells, placing a stretch on the cell that increases long-term growth. Most recently, creatine has been found to increase levels of insulin like growth factor-1 (IGF-1) in muscles, which is critical for stimulating growth.
How to maximize its effects: Take 2-5 grams of creatine in the form of creatine monohydrate, creatine malate, creatine ethyl ester or creatine alpha-ketoglutarate with your protein shake immediately before workouts. This will help keep your muscles saturated with creatine, producing the rapid energy they need to perform more reps. Then consume another 2-5 grams with your postworkout shake (in addition to 40-100 grams of fast-digesting carbs), a time when creatine will be rapidly taken up by muscle cells and the boost in IGF-1 levels will help prompt further growth. On days when you don’t train, take 2-5 grams of creatine with a breakfast that contains carbohydrates.
Why they made the list: The term branched-chain amino acids refers to leucine, isoleucine and valine, the absolute most important amino acids for repairing and building muscle tissue. Leucine is the most critical of the three, as research shows that it can stimulate muscle protein synthesis on its own. Yet it’s still best to take all three together, since they work in synergy to provide a multitude of benefits, including muscle growth, increased energy during workouts, the blunting of cortisol (a catabolic hormone that inhibits testosterone and increases muscle breakdown) and decreased delayed-onset muscle soreness.
How to maximize their effects: Take 5-10 grams of BCAAs with breakfast, as well as in your pre- and post-workout shakes. Look for BCAA products that provide leucine at a ratio of 2:1 per dose of isoleucine and valine. For example, if you take a 5-gram dose of BCAAs, about 2.5 grams should be from leucine, 1.25 grams from isoleucine and 1.25 grams from valine.
Why they made the list: In the body, the amino acid beta-alanine is combined with another amino, histidine, to form carnosine. Research shows that when muscles have higher levels of carnosine, they have more strength and endurance. Carnosine appears to increase the muscle fibers’ ability to contract with more force, and to do so longer without fatiguing. Several studies reported increases in muscle strength and power in athletes who took beta-alanine. One recent study found that subjects who took beta-alanine along with creatine gained more muscle mass and lost more bodyfat than subjects who took only creatine.
How to maximize their effects: Take 1-2 grams of beta-alanine or carnosine immediately before and after every workout in addition to your shakes and creatine. On non-workout days, take 2 grams with breakfast, along with creatine.
Why they made the list: Nitric oxide (NO) is a molecule found throughout the body that’s involved in multiple processes. The one that bodybuilders are most interested in is its ability to dilate blood vessels, which allows more blood flow to the muscles for enhanced delivery of oxygen, nutrients, anabolic hormones and water (blood is mostly water). This gives you more energy during your workout, an enhanced muscle pump, and better muscle recovery and growth after the workout. NO boosters don’t provide NO, but rather the amino acid arginine, which is readily converted to NO in the body. Research has found that subjects who were given arginine increased muscle strength and growth and lost bodyfat.
How to maximize their effects: Take an NO booster that provides 3-5 grams of arginine in the form of L-arginine, arginine alpha-ketoglutarate, arginine ethyl ester or arginine malate. Also, consider NO boosters that provide ingredients such as citrulline, pycnog-enol and American ginseng, which enhance arginine’s ability to increase NO. Take one dose at each of the following times: in the morning before breakfast, 30-60 minutes before training, immediately after training and 30-60 minutes before bedtime. When possible, take each dose without food and consider combining it with 500-1,000 mg of vitamin C, which can help maintain levels of NO for longer.
Why it made the list: This amino acid has been a favorite of bodybuilders for decades because it’s central to muscle function and is one of the most plentiful aminos found in the human body. Glutamine provides numerous bodybuilding benefits, such as aiding muscle growth by increasing levels of leucine in muscle fibers, helping decrease muscle breakdown and bolstering the immune system, which helps prevent you from getting sick and missing workouts. Glutamine taken before workouts can help decrease muscle fatigue and boost growth hormone levels. In addition, recent research shows that glutamine might also play a role in fat loss by increasing the amount of calories and fat burned at rest and during exercise.
How to maximize its effects: Take 5-10 grams of glutamine in the morning with breakfast, with your pre- and post-workout shakes, and with your nighttime snack.
Why it made the list: ZMA is a combination of zinc, magnesium aspartate and vitamin B6. It’s an important supplement because hard-training athletes such as bodybuilders are often deficient in these critical minerals, which are important for maintaining hormone levels and aiding sleep (essential for recovery). Intense training can compromise levels of testosterone and IGF-1. In fact, one study found that athletes who took ZMA significantly increased their levels of testosterone and IGF-1 during eight weeks of training, while those who took a placebo experienced a drop in both T and IGF-1. Naturally, boosting testosterone and IGF-1 can make huge impacts on muscle gains.
How to maximize its effects: Use a ZMA product that provides about 30 mg of zinc, 450 mg of magnesium and 10.5 mg of vitamin B6, and take it 30-60 minutes before bedtime without any food or calcium. Taking ZMA on an empty stomach will enhance its uptake and utilization and improve your sleep quality for optimal recovery.
Why it made the list: Besides being a popular fat-loss supplement, carnitine is now known to enhance muscle growth through a number of mechanisms, all of which are supported by clinical research. For one, carnitine can increase blood flow to muscles, which means it provides similar benefits to NO boosters. It also increases testosterone levels postworkout and the amount of T receptors inside muscle cells, which allows more testosterone to stimulate more growth. In addition, carnitine supplements have been found to increase levels of IGF-1. Add all these benefits together and you have the potential to gain enormous amounts of muscle.
How to maximize its effects: Take 1-3 grams of carnitine in the form of L-carnitine, acetyl-L-carnitine or L-carnitine-L-tartrate with breakfast, your pre- and post-workout shakes, and nighttime meals.
