Are you feeding your muscles with the right aminos?

1. Your muscles need a carefully crafted balance of the right aminos

A ‘throw everything at the wall’ approach doesn’t work for building lean muscle. Lean & tone aminos+ delivers nine carefully selected essential amino acids (including the three BCAAs) in their bioavailable forms (minimal digestion required). That means your muscles can start using them immediately to help fuel muscle growth, preserve lean muscle, and support strength.*

It’s a powerful complement to a high-protein diet or whey protein powder, especially around workouts or when you need a quick recovery boost.*

2. The leucine threshold isn’t a ‘nice to have,’ it’s critical

2.5 grams of leucine per single serving is a clinically-proven necessity for triggering muscle protein synthesis, full stop. Many aminos fall short, and when they do, you (and your muscles) miss out.

lean & tone aminos+ delivers the full clinically effective dose of leucine, plus the other two BCAAs and six additional EAAs, all in a balanced ratio inspired by high-quality protein.* You deserve to get exactly what you’re paying for: an effective, science-driven supplement shownproven to build lean muscle.*

3. Transparency matters

Tired of ‘proprietary formulas’? So were we. That’s why there are no blends and no guesswork with lean & tone aminos+. We list all 9 essential amino acids in their exact, science backed doses right on the label. Most amino supplements don’t, which means you never really know what (or how much) you’re getting—especially when it comes to critical ingredients like leucine.

lean & tone aminos+ is formulated for transparency and real results. Because you deserve to know what you're putting in your body—and that it’s actually working.*

No blends. No guessing. Just pure amino acids.

Branched-chain amino acids (BCAAs)

The leucine threshold isn’t a ‘nice to have,’ it’s critical

Without 2.5 g of leucine, muscle protein synthesis fails to kickstart. Unlike leading competitors, lean & tone aminos+ properly doses the clinically-proven amount of leucine to ensure effective muscle building, paired with 9 essential amino acids. In short, the full toolkit to support your body’s lean muscle. This is all blended into a delicious mixed berry formula with no artificial sweeteners or fillers. We only include what’s needed to get the best out of your body’s performance:*

  • Fuel muscle building & repair
  • Preserve lean muscle mass, even during hormonal shifts
  • Bounce back faster after workouts
Additional EAAs

Complete spectrum of essential amino acids

Your body needs all 9 essential amino acids to fully support muscle health and overall wellness, the BCAAs only account for three. That’s why we round out this formula with the 6 additional essential amino acids (in balanced amounts inspired by high-quality proteins). Together, these amino acids help to:*

  • Build lean muscle and strength
  • Support total-body energy and recovery
  • Help keep joints and muscles strong

What’s the leucine threshold?

Your body needs about 2.5 grams of leucine in one go to fully flip that muscle-building switch. Anything less and your body won’t get the full benefits. That’s why our formula delivers a clinically effective dose in each serving, so you can exactly see results from your routine.*

So what exactly is Leucine? Meet leucine

Leucine is one of three BCAAs, and it’s the on switch of muscle protein synthesis, the process muscles use to build and repair themselves. The kicker is that you can't just have a little bit of leucine here and a little bit there and call it a day.*

Why you need more with age

As we age, our muscles naturally need a bigger push to grow and repair. Muscle protein synthesis slows down and reaching that leucine “threshold” matters even more. Even if you eat plenty of protein, you still have to get enough leucine at each meal, and diet alone doesn’t always cut it. That’s where lean & tone aminos+ come in.*

How It Works

Mix 1 stick in 8 fluid ounces of your preferred beverage or meal daily to start seeing benefits of lean & tone aminos+ over time.*

Week 1+: Promote muscle protein synthesis & muscle recovery*†

6-8 weeks+: Enhance physical performance & lean body mass*†

3 months+: Support lean muscle mass & strength*†

6 months+: Continues to promote muscle & performance benefits with consistent use*†

    Aminos supplement

    This formula tastes very sweet. I don’t enjoy drinking it. I also wish the powder would come in a container with a scoop to save on all the packaging. This would be great for on the go but I feel wasteful using it at home

    Awful sweet taste.

    Wish this supplement came in an unflavored option. This is so sweet and not-so-good flavor. Can I get my money back? Guess I won’t know if it makes a difference or not because I can’t stomach it.

    Worst Tasting Supplement

    This by far has been one of the worst tasting supplements I’ve ever forced myself to drink. It tastes like horrible cold medicine. Do not recommend.
