It’s essential to fill any gaps in your diet by using muscle gain supplements to continue building muscle mass effectively. One of the best ways to maximize the benefits of sports nutrition is to use them synergistically. This guide will help beginners understand which supplements are best for muscle gain.
The basis of our muscle tissue is protein; therefore, without a sufficient amount of it, muscle development is impossible. It happens because the protein itself consists of significant compounds – amino acids, which are necessary for nutrition and the growth of fibers.
✔️ Protein
Among different kinds of sporting nutrition products, protein is almost a key element, as people engaged in weight training, especially, need protein and amino acids. Lacking this element will prevent you from gaining desired muscle mass and, therefore, from achieving your set goals.
Due to the amino acids that proteins consist of, they can perform several functions: gain muscle mass, reduce fat, maintain physical form, etc. That is why, before using it, it is necessary to know what kinds of protein there are, and what the effects of their use are.
According to a [Phillips, Journal of Nutrition, 2011] meta-analysis, “Protein supplementation during resistance exercise training promotes gains in muscle mass and strength, especially in untrained or older adults.” Whey protein, rich in essential amino acids like leucine, is specifically noted to stimulate muscle protein synthesis more than plant or other animal sources.
Here are 8 types of proteins:
- Whey Protein Concentrate
- Casein
- Protein hydrolyzate
- Whey Protein Isolate
- Soy protein
- Egg protein
- Milk protein isolate
- Collagen hydrolysate
✔️ Nitric Oxide Boosters
Nitric Oxide Supplements are becoming increasingly popular these days for building muscle. However, nitric oxide also offers several remarkable health benefits, making it a popular choice for anyone seeking to enhance their well-being.
Nitric Oxide is a gas that is produced naturally within our bodies. It helps to increase the flow of blood to our muscles during intense exercise and can be beneficial to anyone over 40 who wishes to improve their circulatory health.
Nitric Oxide supplements do not contain NO directly; instead, they contain ingredients, particularly l-arginine, which increase the production of NO within your body. Many also contain antioxidants to keep the NO from being destroyed too quickly. NO can be extreme – anyone having lower blood pressure should avoid taking it. It is highly beneficial to those who need it.
It was named “Molecule of the year” in 1992 when many of its beneficial effects were discovered. It’s more helpful to cardiovascular health than just lowering your cholesterol level.
After transformation, L-arginine is converted into NO, which increases blood circulation by enlarging blood vessels. It helps to fill your muscles with blood when you are using them intensely. It is essential to carry a larger amount of nutritional components to the muscles when you exercise.
This process occurs whenever you work out, and new capillaries form within the muscles to help facilitate this process. Intense exercise depletes the body’s supply of NO, which is why many athletes and bodybuilders seek to replenish it with supplements.
As highlighted by the [ISSA, 2023], “L-arginine supplementation can enhance nitric oxide production, leading to greater vasodilation, increased blood flow, and improved nutrient delivery to muscles during exercise.” Peer-reviewed trials show moderate increases in exercise performance and muscle pump in resistance-trained subjects.
✔️ HGH Releasers and Bodybuilding Peptides
The key controllers of HGH secretion are hypothalamic peptide hormones, known as somatostatin and somatoliberin. These are secreted by the hypothalamus with the help of neurosecretory cells.
However, several physical aspects influence the stability of the hormones and the release of somatotropin. Experts have proved that HGH release can be improved three or four times, with no hormonal mediators.
HGH release stimulants:
Bodybuilding peptides are the most potent stimulants of HGH. The price of a similar course is much lower:
GHRP-6, GRF (1-29), Ipamorelin, CJC-1295, HGH Frag (176-191) – fragment, GHRP-2
According to a [Innerbody, 2025] review, “CJC-1295 and Ipamorelin have shown in multiple clinical studies to increase growth hormone output, improve recovery, and enhance lean mass.” These peptides stimulate pituitary secretion of endogenous HGH, which in turn supports fat loss, cellular repair, and muscle gain.
Other important things:
- Enough sleep
- Physical exercises (aerobic exercise is almost 2 times more pronounced than weight training)
- GABA
- Protein intake
- Taking L-arginine
- L-glutamine intake
- Hunger – an inappropriate option for bodybuilding
- Creatine – recently, it has been proven that creatine can boost the production of IGF-1
✔️ BCAA (Branched Chain Amino Acids)
BCAA supplements are known for being a group of essential and significant amino acids for muscle building. They are mostly good for damage prevention and muscle recovery, especially after extreme workouts.
BCAAs supplements are not as popular as protein or creatine, but they are gaining popularity. Among the essential amino acids are valine, leucine, and isoleucine. 1/3 of the whole muscles of our bodies consist of them.
How do BCAA Supplements work?
Usually, after a person has an intense workout, his body is in a state known as catabolic. It refers to the wasting of muscles. You must always avoid it!
By consuming BCAA supplements, the problem can be solved. It may become a part of, before, during, and after an intense workout. The muscles, in this case, will be supplied with a massive quantity of nutrients that will surely aid in their rapid rebuilding.
BCAA supplements are great for post-workout. Thus, your body will have the chance to produce a significant number of proteins later on. It’s crucial for athletes, bodybuilders, and not only.
Clinical trials and comprehensive reviews such as [Nutrition Research Reviews, 2024] confirm: “BCAA supplementation helps reduce muscle damage, accelerate recovery, and may stimulate muscle protein synthesis, particularly when dietary intake or timing around exercise is suboptimal.”
✔️ Gainers
Gainer can be the best “build muscles fast supplement” since it consists of carbohydrates and protein. Manufacturers also add creatine, minerals, amino acids, vitamins, and fats to the gainers. Athletes take gainers to increase muscle mass and as an additional energy source.
How does the protein-carbohydrate mix work?
The secret of its effectiveness is in combining the effects of carbohydrates and protein. Independent medical research has long confirmed the efficacy of this combination; the gainer was among the first supplements designed specifically for athletes. It’s true that previously, such products were prepared from the cheapest proteins, sugars, and fats, losing in product quality but gaining in their caloric value.
The primary goal of using gainer supplements in bodybuilding and other weightlifting training is to achieve a rapid increase in muscle mass. Gainers are also great for ectomorphs, individuals with asthenic (lean) physiques who lack excess fat. If you’ve ever wondered how to gain weight for skinny guys with a high metabolism, a gainer is the answer.
A high rate of metabolic reactions distinguishes people of this morphological type, and it may not be sufficient for them to rely on other sports nutrition for systematic training to gain muscle mass and increase strength. Gainers address the issue of insufficient energy and materials for anabolic processes.
A 2023 [Bulking Research Review] summary highlights, “Research confirms that combining fast-digesting carbs and protein post-workout is highly effective at raising insulin, stimulating anabolic hormone release, and maximizing muscle protein accretion in lean individuals.”
✔️ L-Glutamine
L-Glutamine is a conditionally indispensable amino acid. This amino acid is a part of the protein. It is essential for effective muscle growth and immune system support. Glutamine is very common in nature. It is a conditionally essential amino acid for humans.
L-glutamine circulates in large quantities in the bloodstream and mainly accumulates in muscle tissue. It’s the most abundant amino acid in the body, and the muscles consist of 60% of it.
A clinical trial reported in [Nutrients, 2021] found, “L-glutamine supplementation in athletes improved muscle recovery, reduced post-exercise muscle soreness, and supported immune function, especially during periods of intense training.”
✔️ Vitamins and Minerals
Why are vitamins and minerals so significant for athletes?
After extreme physical activity, you are exhausted, and a vast quantity of vitamins and minerals leaves your body. Not maintaining an essential level of vitamins and minerals will interfere with regular workouts in the gym. It can easily slow your muscle growth. In some cases, it can even lead to serious health problems.
What vitamins do athletes need first of all for muscle growth and recovery after exercise?
