The No BS Truth About RSP Amino Lean

Amino Lean is an amino acid supplement which is geared toward weight-loss.  It’s kind of like a BCAA or intra-workout supplement that is supposed to subtly promote weight loss.

Of course the question is:

Does Amino Lean Work?

Well, to answer that questions, there’s only one thing we can really do.  Look at:

  • The Ingredients
  • The Doses Of Those Ingredients
  • Determine Whether They Can Really Promote Weight-Loss

You see, supplements aren’t so complicated when you consider the fact that

the effectiveness of a supplement boils down to the ingredients and the doses of those ingredients.  If the ingredients have been proven to work, and the doses are in-line with what research has determined to be a clinical dose, then you’e got yourself a good supplement.

So, how does RSP Amino Lean stack up?  Let’s get into it…

Amino Lean Ingredients

RSP has opted to use a proprietary blend, which makes it nearly impossible to accurately estimate the doses of each ingredient.  The good news is that RSP breaks it up into groups of ingredients:

  • Amino Acid Blend
  • Fat-Loss Blend
  • Natural Energy And Focus Blend

Although it would be nice to know precise doses of each ingredient, this makes it at least possible for us to make educated guesses about how effective each blend really is.

Amino Acid Blend

Amino Lean’s Amino Acid Blend is comprised of

And also the following amino acids:

  • Arginine
  • Lysine
  • Phenylalanine
  • Threanonine
  • Methionine

With the exception of Citrulline, Beta-Alanine, the BCAAs, and maybe Taurine, these amino acids are all pretty useless.  The truth is, you probably get plenty of them for your diet or even a post-workout protein shake.

They’re just amino acids.  Any protein-containing food supplies everything you need.

While many of the amino acids found in this blend would be effective performance enhancers, almost all of them are undeniably severely under-dosed.

Citrulline alone should be dosed at 6-8g in order to achieve the performance enhancement benefits.  That’s more than the entire Amino Acid Blend.  Doesn’t take a genius to do the math there.

Fat Loss Blend

RSP lists the combine amounts of

at 1500mg per serving, again leaving a lot of guess work determining whether each ingredient is dosed sufficiently.  While not as under-dosed as the Amino Acid Blend, there are certainly some issues here.

First off, as discussed in this article, CLA is not a particularly effective weight-loss agent.

Neither is L-Carnitine L-Tartrate.

Green Tea Extract and Green Coffee Extract can be effective at high enough doses but given that the entire blend is only 1500mg and those two ingredients are listed last, it’s unlikely that the Amino Lean formula does not  contains clinical doses of either.

To be perfectly candid here…

None of the the ingredients will help much (or at all) with losing fat unless combined with some mind of stimulant fat-burner.

Natural Energy Blend

The Amino Lean Natural Energy Level Blend consists of:

  • Caffeine
  • Theobromine
  • Pterostilbene

We’d estimate the total amount of Caffeine at about 100mg, not a particularly high dose but still potentially effective for individuals who don’t regularly consume Caffeine.

Caffeine can help facilitate fat-loss by triggering the release of Catecholamines, a group of fat-burning molecules (hormones) which are also responsible for the feelings of increased alertness and focus.

Theobromine is a chemical relative of Caffeine (they’re both considered Xanthines), but there’s no evidence that it can help facilitate fat-loss.

What To Expect With Amino Lean

Assuming you take enough, Amino Lean may promote exercise recovery and improve performance, but the fat-loss aspect of the formula is pretty weak.  The truth is the fat-loss ingredients just aren’t very effective.

It’s a nice thought…

An amino acid supplement that you can sip on all day knowing that it’s burning extra fat, but keep dreaming.

If you want a supplement that increases the amount of fat you burn, check out our Best Fat Burners list.

The Bottom Line

Amino Lean is pretty disappointing.  Nearly all of the ingredients are under-dosed, in some cases quite severely, and two out of the four weight-loss ingredients just don’t work well to begin with.

It seems RSP is continuing to capitalize off the uneducated supplement consumer by using proprietary blends, a tactic that we really hope to see the end of in the next couple years.

If you’re interested in a BCAA/Amino supplement that actually works, check out our number one rated Amino Beyond (created by Matt Theis) or check out our Best BCAA Supplements List!

This article was written by me, Matt Theis, Founder of SuppWithThat.com and Founder of Momentum Nutrition.  This isn’t a review.  It’s simply a breakdown and assessment of the Amino Lean formula.

My opinions are my own (of course), but the scientific facts I laid out are just that; scientific facts.

Take it with a grain of salt if you want, but I’ve spent the last 5 years of my life trying to help people become more educated with supplements.

My goal is never to talk badly about another brand.  By all means, give RSP’s Amino Lean a chance!

But if you’re looking for an amino acid supplement that actually contains clinical doses of scientifically proven ingredients which will:

  • Enhance Performance
  • Promote Recovery
  • Support Muscle Growth

You can check it out Amino Beyond here or on Amazon.  If weight-loss is your goal, considering stacking it with Rauwolscine or check out our best fat burner list for some clinically dosed, effective fat-burning supplements.

I hate to see people waste their hard earned cash on supplements that just aren’t what they claim to be.
