How Many Grams of Amino Acids Do You Need Per Day? (2023)

When it comes to how many grams of amino acids you need in a day, the dose is generally given in grams. How the body responds to essential amino acids depends on how many grams it consumes. A dose as little as 3 grams can significantly stimulate muscle protein synthesis.

However, the ideal daily intake of amino acids varies based on factors such as your height, body weight, lean body mass, activity level, and so on. Before we examine how these factors affect how many grams of amino acids you need in a day, let's review why you need amino acids in the first place.

Why you need amino acids

It is common to think of amino acids as the building blocks of proteins. In fact, all dietary protein sources (both animal and plant proteins) contain the same 20 amino acids. However, the proportion of amino acids varies from protein to protein.

Throughout the day, your body uses and recycles far more protein than most people consume in a day. Amino acids can be reused to some extent, but it's still important to ensure your body is getting a good and constant supply of these vital compounds. Regardless of your age, according to theSubcommittee of the United States National Research Councilon recommended dietary amounts: "A steady supply of dietary amino acids is required to make up for these losses even after growth has stopped."

Humans cannot synthesize 9 of the 20 amino acids. This means that the many vital jobs amino acids are responsible for are available only to those you get from your dietary protein intake. For this reason, these nine — histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine — are referred to as theessential amino acids.

Three of the essential amino acids, isoleucine, leucine and valine belong to a subgroup called amino acidsbranched chain amino acids. They are often secreted from other amino acids and are particularly popular with athletes because they have been shown to improve exercise performance, reduce muscle soreness and improve recovery, improve body composition and activate muscle protein synthesis.

The 11 remaining amino acids are consideredimmaterial, not because the body doesn't need them for muscle building and other vital functions in the same way as essential amino acids, but because the body can synthesize them itself.

A further seven of these may become indispensable under certain circumstances, for example in the event of liver damage. They are known asConditionally essential amino acids.

While different amino acids have their own unique properties and responsibilities, for optimal health and wellness you must provide all 20 amino acids your body needs - and provide them in the appropriate concentrations.

How Many Grams of Amino Acids Do You Need in a Day?

When determining how much of a nutrient you need on a daily basis, it's common to consider macronutrients in the diet (protein, carbohydrates, and fats) as onepercentthe total calorie intake. But when it comes to how many grams of amino acids you need in a day, what is generally referred to is the doseGrammamounts. For example, the number of calories in an pure essential amino acid (EAA) supplement is insignificant in the context of total caloric intake, and for this reason supplements are generally sold in units of grams (g).

The Standard: A 3-gram dose of amino acids

How the body reacts to EAAs depends on how many grams it gets. A dose of just 3 grams can stimulatemuscle protein synthesissignificant. Taking a 3 gram EAA supplement can produce almost 6 grams of muscle protein - the perfect balance of EAAs allows the muscle to incorporate each and every one of the EAAs into protein. The body also recycles readily available non-essential amino acids to contribute to the total amount of protein produced.

While a 3 gram dose can be effective over time, the amount of muscle protein made from this small dose is limited to the amount of EAAs consumed relative to the size of the muscle mass. While the production of 6 grams of muscle protein from 3 grams of EAAs is impressive, it's not a huge amount of new muscle protein compared to total muscle mass.

Muscle mass can range from 25 to 80 pounds depending on gender, height and body type. Certain EAA benefits,like the anti-inflammatory effect, activate immediately at a dosage of 3 grams, but it will take some patience before you see the benefits in terms of muscle size and strength - at least a month of regular consumption, preferably twice a day, to achieve noticeable gains in muscle mass and Function.

The maximum: A 15-gram dose of amino acids

The amount of muscle protein produced in response to EAA ingestion increases linearly up to a dose of 15 grams. Quite simply, a larger dose will give you a stronger response, but more than 15 grams is unnecessary. As long as you wait at least 1 hour after a dose before taking another dose, you will get the same response to each of the multiple doses in a day.

So there is a wide range of possible doses of EAAs. The appropriate dose depends on your desired results and how quickly you want to achieve them.

If you're on the smaller side and looking to support muscle health, a base dose of 3 grams is appropriate. For example, a petite woman of about 105 pounds with about 30 pounds of muscle will have a robust response and see positive effects over time with a 3 gram dose of EAAs.

A young healthy male who weighs 200 pounds and has a muscle mass of about 80 pounds would be better off with a 6 gram dose of EAAs. (A 3 gram dose would only account for 0.008% of muscle mass, so 6 grams would be more appropriate to account for the larger muscle mass.)

Two doses per day, between meals, is optimal, but you will still get positive effects if you only take one dose per day.

In addition to your protein needs based on your body fat and muscle percentage, your preferred activities and goals affect both the amount of amino acids you need in a day and the optimal time to take those amino acids. If your main goal is to facilitate weight loss, and especially if you are restricting your calorie intake, consider taking 15 grams of amino acids five times a day. But those focused on healthy aging should consume 3-6 grams of amino acids once or twice a day between meals.

The important point to keep in mind is that EAAs are necessary nutrients that serve many functions in the body beyond just being components of muscle protein. A small dose of 3 grams can have many positive effects in addition to muscle building, such as: B. promoting fat loss, so even a large muscular man will benefit from a small dose. The activities one engages in and the desired results from EAA supplementation are likely more important than a person's size or physical condition.

How to take essential amino acid supplements

EAAs can be consumed either as a powder dissolved in water, as a capsule, as a drink, or as a combination of all three.

EAA supplements usually contain amino acids and some flavor. It is common for around 20-25% of a dietary supplement's weight to be flavorings. When determining the right EAA dose for you, make sure you use the weight of the active component of the blend (i.e., the EAAs) and don't include the weight of the flavor. If you are using a supplement that contains a mixture of free EAAs and protein, add the EAA component of the protein to the amount of free EAAs to determine the dose you are consuming. For example if you are using a supplement that contains 3 grams of free EAAs and 1.5 gramsWhey proteinYou consume about 4.5 grams of EAAs since whey protein contains about 50% EAAs.

If you are taking EAA supplements because your regular diet does not meet recommended intakes of quality protein, then in addition to snacking, I recommend taking supplements with your meals to increase the physiological effectiveness of taking EAA from the incomplete protein sources in your Nutrition. Meal dosing to compensate for deficiencies depends on how far your diet falls short of the goal of providing quality protein. in case of anvegan diet, which can be up to 15 grams of EAAs at each meal for optimal results.

Optimal EAA supplementation helps maintain an adequate supply of amino acids in the blood throughout the day to support various physiological functions without the disruptions that typically occur when food is not being consumed. Therefore, for best results, take an EAA supplement twice a day between meals or before bed.

If you're still unsure how many grams of amino acids you personally need in a day, don't worry. The beauty of essential amino acids is that there are no known side effects to a balanced formulation of EAAs, so you don't have to worry about taking too much. A very small dose has been shown to have benefits for stimulating muscle protein synthesis, so you also don't have to worry about under-dosing to see positive results. The recommended dosages are to be understood as guidelines; If you see successful results with a different dose, stick with it.
