7 Best Supplements For Building Lean Muscle And Strength Gain.


Our body is what we feed it. Packing some serious muscle mass doesn’t depend on the amount of weight you lift at the gym, instead, it depends on the quality of nutrition you provide to your body. 

Gaining lean muscle mass is fairly difficult than packing up muscle mass. Although many people gain a fair amount of muscle mass, but not all of them have a lean mass. Most of the gym rats are still struggling to get abs because of the absence of the right guidance. 

Before we move to the best supplements for building lean muscle its important to know some basics about gaining lean muscle mass. 

Here are the tips that every pro athlete use to stay lean and muscular. 

  • More protein = more muscle building. Are you eating a gram of protein for a per pound of bodyweight? If not then its time to introduce yourself to a new diet pattern. 
  • Cutting down carbs can help in packing up some lean muscle mass. Carbs are the main bulking agent and you cant develop lean muscle mass in abundance of carbs.
  • A combination of compound movements and lean muscle building supplements can deliver some phenomenal results. 
  • Persistence is the key to develop your dream body, workout 5 days a week with a systematic workout plan. 
  • Most of the people are not so intentional about the quality of sleep. Sleep plays a very important role in regulating metabolism and faster recovery.

Creatine monohydrate is one of the most extensively researched supplements that has been used by many professional athletes to improve performance and maintain lean muscle mass

Creatine is made from three amino acids: arginine, glycine, and methionine. According to the international society of sports nutrition “Creatine monohydrate is the most effective ergogenic nutritional supplement currently available to athletes in terms of increasing high-intensity exercise capacity and lean body mass during training”.

Creatine basically increases the amount of ATP in muscle cells that delivers that extra push to your workout. That extra boost in energy allows you to grow stronger and bigger. Not just that, creatine also leads to accumulation of water in your muscle cells which stretches the cell walls for better anaerobic performance, strength, pump, and growth

Overall, creatine is a clean supplement that helps in improving athletic performance by improving the production of ATP molecules.  An increase in energy production helps in achieving better workout performance and calorie burning which ultimately leads to the development of lean muscle mass.

No matter what, you can’t really ignore the body’s daily protein needs. Whey protein has always been the most reliable protein source to develop some serious muscle mass. 

Whey is a milk protein that is derived after an extensive filtration process. 

But not all the whey protein supplements are created equal, they all differ in the carb content and purity. 

If you are looking for a lean muscle development then you should not choose anything less than 100% Isolate whey, these whey contains almost zero carbs and has high dissolvability. 

If you are looking for the purest form then you can opt for Hydrolyzed whey protein, these are the predigested whey protein that is very high absorption rate. 

A 10-week study conducted on the effects of whey protein on lean muscle gaining found some impressive development in overall body composition and lean muscle mass. 

Whey provides all the essential amino acids that are required for fast recovery and strength development after an intense training session. 

If you are looking to improve your workout gains then it’s recommended taking 20-40 grams of whey isolates for fast recovery

Another important benefit that you need to look up to is its ability to strengthen the immune system and gut health (11, 12, 13). Improved gut health leads to better absorption of nutrients.

Although Carnitine doesn’t have any direct muscle-building effects but it plays an important role in the lean muscle building process. 

Main mechanism of carnitine is to push stored body fats into cell mitochondria for the production of energy. This process helps in the utilization of stored fats for energy, it works really well when combined with clean food and right diet pattern. How does it help in lean muscle development? Here is the reason:

  • It helps in fueling the body with extended energy which results in the improved workout. 
  • It pushes stored fat into cell mitochondria that leads to an overall reduction in body fat.
  • Improves blood circulation which results in a better supply of nutrients and faster recovery (20, 22). 
  • It may decrease muscle soreness(21). 

Other Frequently Asked Questions:

There are some most common questions related to muscle gaining that are being constantly asked by most of our readers, here is an answer to

Best protein powder for weight loss and muscle gain?

There are many types of protein powder available in the market, some of the common protein powder are: 

  • Whey protein
  • Casein protein
  • Pea protein
  • Egg protein 
  • Soy protein
  • Hemp protein 

People might have different preferences, I personally love Whey Protein more than any other type. 

Always opt for Hydrolyzed whey protein or 100% whey Isolate proteins, those protein contains no fillers, just pure muscle-building fuel. 

Best combination of supplements for weight loss and muscle gain? 

See, I have already specified the supplements that are helpful in building some serious muscle mass while cutting down excess fat. 

Although I prefer to keep all 6 supplements in my muscle building stack, let me tell you my best dose and time. 

  • Whey protein: 3 scoops of 100% whey isolates in the morning, evening post-workout and Before bed (with some almond milk). 
  • BCAA: 2 scoops of 7g each. I take a half scoop before a workout, 1 scoop intra-workout and another half scoop after workout. 
  • Glutamine: I add up 2 scoops of glutamine in the morning and evening with my whey protein shakes. 
  • Creatine with my Preworkout which contains Beta-Alanine as well. 
  • 1.5g of L-carnitine 2 times a day. 1.5 grams with my pre-workout meal and another 1.5 grams with my post-workout meal. 

How to build muscle fast?

My friend, consistency is the key, there is no magic wand. Pro bodybuilders have been working out for decades for that muscle mass.

You need to be consistent with your diet, workout, and supplementation. 

If you are only concerned about building muscle fast then you should pay more emphasis on strength development, compound movements, and recovery.
