I believe Amino Lean can be a missing link to help you have better workouts and get more results, so let’s start by looking at the Amino Lean formula so you can feel as informed and confident in this supplement as I am.
Amino Lean Benefits & Ingredients
RSP Nutrition Amino Lean is one of my favorite supplements because of its versatility and wide-ranging benefits.
Each of its ingredients plays an important role, and AminoLean combines amino acids, micronutrients, and metabolism-boosting ingredients to help you get leaner, stronger, and healthier.
Amino Acids
Each serving of AminoLean provides 5g of Essential Amino Acids (EAAs).
Energy Support
Amino Lean contains a combination of natural caffeine sources to provide strong, sustainable energy support.
Weight Management Support
One reason Amino Lean is an exceptional supplement is its four evidence-backed, natural fat burners.
Dosage
The recommended dosage of Amino Lean is one scoop mixed with 8-10 ounces of water, taken once or twice daily.
Each dosage contains 5 grams of EAAs and 120mg of caffeine.
Timing
Due to its caffeine, taking Amino Lean pre workout is common.
You can also consume AminoLean Intra workout or post-workout, depending on your goals and needs.
Taste
RSP Amino Lean offers a variety of delicious flavors. My favorite flavors are the Vegan Amino Lean Pineapple Coconut and Acai.
Pros
Cons
As I mentioned previously, AminoLean combines amino acids, micronutrients, and metabolism-boosting ingredients to help you get leaner, stronger, and healthier.
Each of its ingredients plays an important role, and its unique combination of ingredients is one of the primary reasons I believe it is the best amino acid supplement.
Amino Acids
RSP Nutrition Amino Lean is an Essential Amino Acid supplement (EAA), so each serving contains all of the essential amino acids needed to repair your muscles after training sessions because
AminoLean provides 5g of total amino acids per serving, and unlike BCAA supplements, it contains all nine essential amino acids that make a complete protein.
Although the label does not state exactly how much of each amino acid it contains, AminoLean contains these amino acids:
- L-Glutamine
- L-Arginine
- L-Leucine
- L-Isoleucine
- L-Valine
- L-Citrulline
- L-Histidine
- L-Lysine
- L-Threonine
- L-Methionine
- L-Tyrosine
These amino acids stimulate protein synthesis and mitigate muscle breakdown during physical activity, enabling users to efficiently build and sustain lean muscle mass.
Furthermore, EAAs and BCAAs can help reduce exercise-induced fatigue and muscle soreness, thereby shortening recovery time between workouts.
As a result, AminoLean empowers athletes and fitness enthusiasts to experience accelerated recovery, increased muscle growth, and, ultimately, an elevated overall performance level.
Along with these amino acids, RSP Amino Lean also contains Beta-Alanine and Taurine.
Beta-Alanine is especially useful as it has consistently been proven as an effective supplement for improving athletic performance, increasing exercise capacity, and reducing muscle fatigue.
Energy Support
One of the standout features of AminoLean is its natural caffeine and energy blend, which provides a steady and sustained energy source throughout the day.
Amino Lean contains a combination of natural sources of caffeine, such as green tea extract and green coffee bean extract, to provide sustained energy, mental alertness, and additional metabolism-boosting effects.
This energy boost enables users to maintain focus and mental alertness during workouts, translating to more effective and productive training sessions.
But the benefits don’t stop at physical performance, its unique formulation may also offer cognitive advantages.
By combining natural caffeine, amino acids, and other ingredients, AminoLean helps improve focus, mental alertness, and overall cognitive function, resulting in better workouts and increased productivity in daily life.
Weight Management Complex
One of the primary reasons I consider Amino Lean an exceptional supplement is its inclusion of four evidence-backed, natural fat burners that can potentially enhance weight loss efforts.
- CLA
- L-Carnitine
- Green Tea Extract
- Green Coffee Bean Extract
Amino Lean’s distinct weight management and appetite control blend facilitates the breakdown of stored fat and assists in curbing hunger.
Consequently, users can more easily attain a calorie deficit, resulting in optimized fat-burning and weight loss.
Incorporating Amino Lean into your routine provides the nutritional support to build lean muscle and efficiently shed excess weight, ultimately making it easier to achieve the body composition you desire.
Green Tea Extract
Green tea extract is rich in antioxidants, particularly catechins, which have been shown to positively impact weight loss and management.
Green tea can promote weight loss for multiple reasons, and green tea extract is a particularly powerful way to use green tea for weight loss.
The most well-known catechin is EGCG (Epigallocatechin gallate), which has been found to increase fat oxidation and improve thermogenesis (the process by which the body generates heat and burns calories).
Green Coffee Bean Extract
Green coffee bean extract is derived from unroasted coffee beans and contains a high concentration of chlorogenic acid.
Chlorogenic acid has been shown to influence glucose and fat metabolism, which can help reduce carbohydrate absorption and support fat breakdown.
Conjugated Linoleic Acid
Conjugated Linoleic Acid (CLA) is a naturally occurring fatty acid found in meat and dairy products.
Research suggests that CLA may help promote weight loss by influencing energy metabolism, reducing body fat storage, and increasing fat breakdown.
Some studies also indicate that CLA can help preserve lean muscle mass while promoting fat loss, which is essential for maintaining a healthy body composition.
L-Carnitine
L-Carnitine is an amino acid vital in transporting long-chain fatty acids into the mitochondria, where they can be burned for energy.
By facilitating the use of stored fat as fuel, L-Carnitine can help increase fat oxidation, thereby supporting weight loss and weight management efforts.
Additionally, L-Carnitine has been shown to reduce fatigue and improve exercise performance, leading to more effective workouts and increased calorie burning.
New Formulas
RSP Nutrition has expanded the AminoLean line in recent years with unique formulas to fit certain health and fitness needs.

Vegan AminoLean Review
Although the original RSP Nutrition Amino Lean formula is great, RSP Nutrition also makes Vegan AminoLean, a 100% vegan amino acid supplement that I believe is even better!
The main difference between RSP Vegan Amino Lean and regular Amino Lean is the source of protein.
The classic AminoLean formula is made with amino acids taken from animal sources, while RSP Vegan Amino Lean is made with plant-based amino acids.
This means that RSP Vegan AminoLean is suitable for vegans and vegetarians, while regular AminoLean is not.
Both supplements contain Green Tea Extract, Caffeine, and CLA.
However, Vegan Amino Lean is free of animal products, artificial sweeteners, gluten, and soy, making it suitable for people with specific dietary restrictions.
Additionally, the vegan formula contains better caffeine sources (guarana and organic matcha).
I prefer Vegan Amino Lean because it is all-natural and does not contain anything artificial!
It is slightly more expensive but also a more natural product.

AminoLean Max Review
RSP AminoLean Max is RSP Nutrition’s newest pre workout supplement, with the highest caffeine content of any of their supplements.
I bought one bottle of RSP AminoLean Max as soon as it was released, and I have had a fantastic time using it so far!
Like Vegan Amino Lean, Amino Lean Max is vegan and contains no artificial flavors or dyes.
AminoLean Max contains a beneficial amount of BCAAs (1.5 grams in a 2:1:1 ratio) and a small quantity of other EAAs.
The amino acid content of AminoLean Max is lower than other AminoLean products, but it is still beneficial.
A key difference in RSP Amino Lean Max is that it contains 1.6 grams of Beta-Alanine, a well-researched supplement for assisting with various goals.
Additionally, AminoLean Max contains 250mg of natural caffeine, 250mg of L-Tyrosine, and additional ingredients to help you “get a pump” in the gym and have energy for longer workouts.

Potential Side Effects
While RSP Amino Lean offers numerous benefits, it’s essential to be aware of the potential side effects of Amino Lean and how to minimize risks.
As with all dietary supplements, some individuals may experience unintended or undesirable effects.
Although Amino Lean is not a medication and does not have “side effects” in the traditional sense, there are still potential risks.
To minimize the potential side effects of Amino Lean, it’s crucial to read and follow the instructions on the label carefully.
If you’re unsure whether Amino Lean suits your needs, consult a healthcare provider before incorporating it into your fitness routine.
Insomnia: Amino Lean contains caffeine, which can interfere with sleep if consumed too close to bedtime.
To avoid this issue, avoid taking it before or during a nighttime workout or within a few hours of your intended sleep time.
Nausea and Upset Stomach: Some users may experience mild nausea or stomach upset when first taking Amino Lean.
To minimize this risk, consider starting with a lower dose and gradually increasing it as your body adjusts to the supplement.
Additionally, taking Amino Lean with a small meal or snack may help reduce gastrointestinal discomfort.
Headache: In rare cases, users may experience headaches when taking Amino Lean.
This side effect may be attributed to the caffeine content or individual sensitivity to specific ingredients.
If headaches persist or worsen, consider reducing the dosage or discontinuing use.
Dizziness: A small number of users may experience dizziness after taking Amino Lean.
This side effect is generally temporary and may be due to individual sensitivity to certain ingredients. If dizziness continues or becomes bothersome, consult a healthcare provider before continuing the supplement.
Recommended Dosage and Timing
To get the most out of Amino Lean, it’s essential to follow best practices for timing and dosage.
Dosage
The recommended dosage of Amino Lean is one scoop mixed with 8-10 ounces of water, taken once or twice daily.
Each dosage contains 5 grams of EAAs and 120mg of caffeine, and one dosage of this supplement is two “scoops.”
For starters,I recommend mixing one scoop of Amino Lean with 8-10 ounces of water and shake well to make the drink.
You can adjust the water amount to achieve your desired taste and consistency, and try taking the supplement with a small meal or snack if you experience gastrointestinal discomfort when taking it on an empty stomach.
However, I often take Vegan AminoLean on an empty stomach and haven’t noticed any negative stomach effects.
Timing
Due to its caffeine content, taking Amino Lean pre workout is common.
However, this supplement can also be consumed during your workout, as the amino acids in the formula help fuel your body throughout longer training sessions.
This, in turn, can help reduce muscle breakdown, initiate recovery, and minimize muscle soreness.
Beyond its workout applications, you can also consider using it as an alternative to your daily cup of coffee, whether as a morning pick-me-up or a mid-day energy boost.
However, you should avoid consuming it too close to bedtime, as the caffeine content may interfere with sleep.
Is AminoLean a Good Pre Workout?
I take two doses or four “scoops” of Amino Lean pre workout or one dosage (two scoops) as an afternoon pick-me-up as needed.
You can use this supplement in multiple ways, but using Amino Lean as a pre workout supplement is an excellent way to maximize its benefits.
In fact, taking AminoLean pre workout is one of my favorite ways to get more out of my workouts.
For optimal results, I recommend consuming Amino Lean pre workout 15-30 minutes before your training session.
This timing ensures you receive a boost in energy and support for positive body composition changes during your workout.
Drinking Amino Lean pre workout has advantages over many other pre workout supplements because it has a moderate amount of natural caffeine per serving that won’t make you jittery.
Taste
RSP Amino Lean offers a variety of delicious flavors that cater to different taste preferences, ensuring that there’s something for everyone to enjoy.
My favorite flavors are the Vegan Amino Lean Pineapple Coconut and Acai.
I’ve never had any issues with the flavor or mixing of Amino Lean, as the supplement dissolves quickly in water, providing a smooth and enjoyable drinking experience without clumps or residue.
The Vegan Amino Lean has a more natural taste than the original formula, which I truly appreciate.
To get the best taste and texture, I recommend mixing one scoop of Amino Lean with 8-10 ounces of water and shaking well.
You can adjust the water amount according to your desired taste and consistency.
Consider adding ice or chilled water for a colder, more refreshing beverage.

Concluding Thoughts – Should You Buy Amino Lean?
I have been using RSP Nutrition Amino Lean for years, and I believe it is a very beneficial supplement.
However, you should decide for yourself if you want to buy it.
When you spend your hard-earned money on a product that is supposed to improve your health, it better work! I have wasted (way) too much money in my life on useless supplements and products that I wish I could have back.
RSP Nutrition Amino Lean is well-formulated and has worked for me. It is one of my favorite supplements, and I believe it is the best EAA supplement and one of the best pre workout supplements.
In my experience, this supplement can provide energy for workouts and help improve your body composition.
If those are your primary goals, this would be a good supplement.
I hope my RSP Nutrition Amino Lean Review has helped you. Please let me know if you have any additional questions.
