As a rule of thumb, we suggest only four types of supplements: protein powder, creatine, nitric oxide boosters, and weight gainers. This article will be detailing the best supplements for muscle growth in each category.

Protein Powder

Whey protein has been scientifically proven to have the highest rate of absorption among all proteins, including soy and egg whites. It’s also incredibly high in leucine, which can increase muscle mass by stimulating the release of hormones that build muscle. Whey isolate is the purest form of whey protein and will be the first ingredient you look for. If it’s not, move on to a different brand. Whey concentrate contains less protein per serving than isolate, but it also has less lactose and carbs. While some people can digest it just fine, those who have trouble with whey may prefer concentrate.

Creatine

Creatine is the single most scientifically backed supplement on the market. It’s been proven beyond a shadow of a doubt to increase strength and power, which will enable you to lift heavier and train harder. There are tons of different types of creatine on the market today, but they’re all made from three basic compounds: monohydrate, citrate, and nitrate. Choose monohydrate for the best bang for your buck, especially if you’re on a budget. This tried-and-true form of creatine has been used successfully by athletes all over the world.

Nitric Oxide Boosters

Nitric oxide boosters are some of the most popular products on the market today. They tend to be a bit pricey, but they deliver rapid results in the gym because they’re stimulant-based. These products contain L-arginine, which is converted into nitric oxide within your body. By increasing your NO production, you’ll feel an intense sensation of blood flow that will immediately translate into bigger lifts in the gym. Choose any NO product that contains L-citrulline, which is actually better for your body to use than L-arginine. The additional benefit of purchasing a product like this is that it tastes like candy and has very few side effects (it’s not as stimulating as other types of NO boosters).

Weight Gainers

Though they aren’t as popular as they used to be, weight gainers can be a very useful tool for those who have difficulty packing on size. Since they contain tons of protein and carbs per serving, they’re the most efficient way to get big without resorting to frequent meals throughout the day.

Casein

Casein is another popular type of protein that makes a good compliment to whey. It absorbs more slowly than whey, allowing for a steady release of amino acids over several hours.

Egg Albumen

This is actually the complete egg white, but it’s filtered and dried to remove the fat and cholesterol so that all you’re left with is pure protein. It contains high amounts of cysteine, an amino acid needed for producing glutathione, which helps eliminate free radicals.

Milk Protein Isolate

This type of protein is similar to whey in that it’s a byproduct of the cheese-making process, but it isn’t as well studied and doesn’t have quite as much research backing its effectiveness. Still, it does perform relatively well in most studies and is very popular among bodybuilders for its low lactose content.

Branched-Chain Amino Acids (BCAAs)

BCAAs are the amino acids leucine, isoleucine, and valine. They’re critical for muscle growth because they stimulate your body to produce more human growth hormone (HGH), which helps you build lean mass when combined with resistance training. BCAAs also reduce post-workout fatigue by fighting off cortisol — the stress hormone that breaks down muscle tissue. They can be found in protein powders, of course, but you’ll also find them sold as single supplements. Pure BCAA powder is considered to be the best value because it’s much cheaper than buying BCAAs in pill form.

Testosterone Boosters

Testosterone boosters come in several forms, but all of them work similarly. They contain a variety of herbs and extracts that stimulate your body to make more testosterone, such as tribulus terrestris and longjack (a type of tongkat ali). Though they won’t boost your testosterone production if it’s already normal or low, they can help you increase your T levels by as much as 50% if they’re deficient. The best boosters contain a 100:1 extract of longjack, which is the most potent form available .

Carnitine

This amino acid-like compound helps shuttle fatty acids into your mitochondria so that they can be used for energy. It’s especially useful for burning off the fat that covers your abs and obliques, which can make getting lean easier.

Best Supplements for Muscle Growth

Many people feel whey protein is the best way to go, especially for those who are lactose intolerant or have a hard time digesting large quantities of proteins. However, feel free to experiment with different forms of protein and find which one works best for you. Creatine is another popular supplement that will almost certainly elicit a positive result. There’s no such thing as “too much” creatine, so feel free to experiment with different forms and dosages until you find the perfect one for you. Nitric oxide boosters are third on our list of muscle-building supplements, but they’re still very popular among bodybuilders because they work. They’ll increase your energy in the gym and enable you to lift heavier weights than ever before. Just remember that NO boosters are casual supplements, not necessities. You can definitely get big without them if you’re willing to put forth the effort. If you have trouble gaining weight, then a quality weight gainer is probably your best bet. They’re very dense in calories (700 to 800 per serving) and contain 50 grams of protein, which is more than most people eat in an entire day. Plus, they taste like dessert. Remember, however, that not all weight gainers are created equal. Oftentimes they’ll contain cheap protein sources like maltodextrin and sodium caseinate (a slow-acting form of casein). If possible, stick with a product that uses whey concentrate instead. Vitamin D is essential for everyone — men and women alike. It enables your body to absorb calcium, which is essential for strong bones and teeth. Vitamin D supplements are also very useful for preventing the flu during cold weather months. Taking supplements to help with your overall health, including muscle growth is a simple way to keep your body functioning as it should.
