Don't Just Read the Front Label. Here Is What 5g of Leucine Looks Like.

Don't just read the front label. Look at what is in the scoop: 5 grams of leucine, essential amino acids alongside it, and every number on the panel in plain view.

Every amino label has a front and a back. The front is where a brand puts what it wants you to notice. The Supplement Facts panel is where the scoop actually gets counted, and it is where a formula either holds up or does not.

So here is how to read one: four checks, in order. Then Aminotaur Essential, run through all four. 5 grams of L-leucine per scoop, a 5:1:1 BCAA ratio, 3.5 grams of EAAs alongside it, an electrolyte blend and 1 gram of L-carnitine tartrate.

The method

Four checks for any amino label

  1. The lead amino, in milligrams. Find leucine and read the number printed next to it, not a blend total with leucine somewhere inside.
  2. The ratio. BCAAs are written as a ratio: leucine first, then isoleucine, then valine. The first number tells you who is leading.
  3. What sits alongside, and how much. Essential amino acids, electrolytes, anything else on the panel: each blend with its total.
  4. What is not there. Sugar. Stimulants. Anything you did not choose to take.

Four checks, thirty seconds. A label that passes them has earned a place in your bag.

The expensive one

Leucine costs more. We did not cut it.

Leucine is the expensive amino. We made it the lead anyway: 5 grams per scoop, two and a half times the isoleucine and valine combined.

Aminotaur Essential sits in our Performance line, from a brand that started out formulating for pro bodybuilders. A verified buyer spotted the dose.

★★★★★

"Great new flavor! Only BCAA/EAA with this kind of dosing and taste. Every other company is underdosed and flavors are medicinal."

Then the taste

A good label still has to taste good

The panel gets it into the bag. The flavor keeps it there. Orange Mango Guava, The Grape Escape, Fresh Squeezed Lemonade and Sour Apple, all on the same formula. Use is simple: one level scoop in water before and/or during training, sipped through the session.

★★★★★

"Great quality BCAA and EAA."

Before you decide

Which line do I check first on an amino label?

The lead amino. On Aminotaur Essential that is 5,000 mg of L-leucine per level scoop, printed as its own line rather than folded into a blend total.

What does 5:1:1 mean?

It is the BCAA ratio: leucine, isoleucine and valine in the proportion 5 to 1 to 1. In one scoop that is 5,000 mg of leucine and 1,000 mg each of the other two, 7 grams of BCAAs in all.

Is it 5 grams of leucine in every flavor?

Yes. Orange Mango Guava, The Grape Escape, Fresh Squeezed Lemonade and Sour Apple share one formula, so the numbers on the panel are the same in each.

What else is in the scoop?

A 3,500 mg EAA blend, 1,000 mg of L-carnitine tartrate and a 2,325 mg Electro-Hydration blend with 1,500 mg of L-taurine, magnesium, potassium, Himalayan salt and coconut water powder.

Where do I see the full Supplement Facts?
