Quick Overview of Muscle Building Supplements

What Are Muscle Building Supplements?

Muscle building supplements are those that help you build muscle, recover and get nutrition. They should be used in addition to a healthy diet and should not be used to replace whole foods.

These products can be in a change of forms including:

• Protein powders
• Creatine
• Amino acid supplements
• Pre-workout formulas
• Recovery drinks
• Meal replacement shakes
• Weight gain powders

The use of vitamin and mineral supplements. Use of vitamin and mineral supplements.

Not all supplements are required for all people. The best options vary based on your diet, training regimen, health and objectives.

How Muscle Growth Happens

Muscle growth is known as muscle hypertrophy and occurs when there is a little stress placed on muscle fibres during resistance exercise. When the body is improving, it repairs and strengthens these fibres, so they produce in size and strength with time.

There are three factors that lead to muscle growth:

Progressive Overload

Progressively overloading muscles with weight, reps or sets will strength them to adapt to the new demand placed on them.

It helps to repair and rebuild muscle tissue after workout.

Recovery

Muscles build during recovery, NOT during exercise. A good night’s sleep, water, and nourishment are all essential.

Nutrition vs Supplements

Supplements are often thought to be the source for building muscle. In fact, they’re just a fraction of the story.

Muscle-building supplements are generally not as effective in promoting muscle building as a regular training program and healthy diet regimen.

Do Muscle Building Supplements Really Work?

There is strong scientific support for the use of some supplements and less or inconsistent research for others.

Factors that determine the effectiveness of a supplement are:

• The ingredient
• The dosage
• Training consistency
• Overall nutrition
• Individual response

There are supplements available to help, but they are not a substitute for hard work and should be used properly to reap measurable benefits.

Supplements with Strong Evidence

Whey Protein

It is a complete protein with all essential amino acids, including leucine. Which is essential for stimulating muscle protein synthesis.

Potential benefits:

• Provides a source for proteins for daily requirement
• Supports muscle recovery
• Convenient after workouts
• Easily digested by many people

Creatine Monohydrate

It has been studied more than any other sports supplement.

There is some research that indicates it can help:

• Increase strength
• Enhance performance in brief and intense activity.
• When paired with resistance training, support the development of lean muscle mass.

Creatine increases the amount of phosphocreatine in the muscles, which can then convert ATP into muscle energy for explosive movements.

Caffeine

Preworkout supplements often contain caffeine.

It could aid to enhance:

• Alertness
• Exercise performance
• Focus during workouts
• Perceived energy

As with anything, moderation is key because there is a difference of tolerance among individuals.

Supplements with Moderate Evidence

There are some supplements which can help some people, but research results are inconsistent.

Examples include:

• The indispensable amino acids (EAA).
• Beta-alanine
• Citrulline malate
• Sodium and potassium replacement

Supplements with Limited Evidence

There is limited high-quality evidence for some products to be marketed for promoting muscle growth.

Examples may include:

• Many commercial “testosterone boosters” supplements contain a mix of proprietary ingredients.
• Some herbal muscle construction supplements
• Muscle gain products that state they contain a certain amount of a specific ingredient but don’t disclose exactly how much.
• Be sure to read them thoroughly and search for products that have ingredient labels and proof that they are effective.

How Muscle Protein Synthesis Works

Muscle protein synthesis (MPS) is the mechanism that the body uses to repair and rebuild muscle proteins following exercise.

Increased protein needs: The body builds up more of a demand for protein when performing resistance training, so dietary intake becomes important.

To support muscle protein synthesis, you should focus on the following factors:The following factors promote muscle protein synthesis:

Regular strength training

• Having enough protein on your plate.Eating enough protein a day.
• As the protein is spread throughout the day, it is distributed evenly.

Adequate sleep

Overall energy intake

How to Choose the Right Supplements

Picking the top muscle building supplements is a tough task. Particularly when you are unsure about the chemicals that go into the supplement.

It’s overwhelming to go into a supplement store or visit a health website, see all the opportunities and selections, and not know what to pick. There are hundreds of products that potential to make you gain muscle fast, bulk up, or make you stronger. The truth is that only a few supplements have scientific evidence that backs them up.

When looking to purchase a supplement, ask yourself the following questions:

• What is my fitness goal?
• Do I have a sufficient amount of protein in my diet?
• Is my training program regular?
• Am I recovering properly?
• Does this supplement really need to be taken?

Supplements are to complement a good nutrition and exercise program, not to replace it.

Step 1: Identify Your Goal

Various supplements are designed for various purposes.

Step 2: Read the Ingredient Label

The following is a list of things that the quality supplement should include:

• Active ingredients
• Amount per serving
• Serving size
• Nutrition facts
• Manufacturer information

Watch out for products that contain:

• Blend that does not reveal the amount of ingredients, also known as proprietary blends
• Unrealistic statements like “Gain 20 pounds of muscle in one month”
• All stimulants are extremely high.

Step 3: Look for Third-Party Testing

Independent testing can safeguard a supplement has the ingredients it claims on the label and is free from some contaminants?

Some of the known third party certification programs are:

• NSF Certified for Sport
• Informed Sport
• Genuine OEM grade supplements, USP Verified (where applicable)

The certifications cannot guarantee that a supplement will enhance performance, but can offer extra confidence on product quality.

Step 4: Compare Cost Per Serving

The lowest-priced container is not necessarily the most cost effective.

Making cost comparisons helps you make a better choice of purchase.

How to Take Muscle Building Supplements

It’s more important to take supplements regularly and properly, than to take big amounts. Most supplements that the scientific evidence supports are better used in conjunction with regular resistance training, sufficient protein intake, sufficient calories and recovery.

Keep in mind that supplements can help supplement a well balanced diet, but not to make up for a balanced meal.

If you don’t consume enough protein in your daily meals, protein powder can be a good solution to help you get the necessary amount of protein.

When to Take It

• After resistance training
• If protein levels are low, between meals
• With breakfast
• As part of a smoothie

Many active adults want to consume protein throughout the day to build muscle protein but they can’t.Many active adults want to eat protein throughout the day to build muscle protein and are unable to do so.

Creatine Monohydrate

The effectiveness of creatine does not depend on when you take it, it’s a product of regular use over time.

General Tips

• Follow a regular daily routine.
• Add water or other fluid to it.
• Stay well hydrated.

There are a couple of options for this, such as beginning with a loading phase, or taking a consistent daily dose. Both can work to boost muscle creatine levels with time, but a loading phase could facilitate this process faster.

Pre-Workout Supplements

Ingredients found in pre-workout products can include beta-alanine, citrulline or caffeine.

General considerations:

• Serve according to the label instructions.
• Don’t use stimulants near bedtime.
• If sensitive to caffeine, use a smaller size of the product first.

Electrolytes

Electrolyte drinks can be beneficial for prolonged exercise, intense training sessions or when exercising in hot temperatures when sweat losses are increased.

For shorter workouts, water is often sufficient.

Sample Daily Supplement Schedule

This is an example only. Individual needs vary based on diet, training schedule, and health status.
