What Is Nutribullet Lean Boost?

Lean Boost is a weight loss shake created by a US-based company named Nutribullet. One 600g tub of Nutribullet Lean Boost contains approximately 30 servings and costs $24.99.

It is available from the official Nutribullet Lean Boost manufacturer website, as well as amazon, GNC, Walmart and several other third-party resellers.

The Lean Boost formula itself is essentially a blend of Pea Protein powder with added green tea extract, chili peppers and flax seeds (among other ingredients) – it’s intended to be used daily, blended up in a Nutribullet Blender.

Consumers are promised effects such as boosted metabolic rates and the optimized ability to burn fat.

Does Nutribullet Lean Boost Work?

Based on our research into this product, we do not believe it will work directly as described by Nutribullet.

This product does not contain any ingredients that will directly and independently boost user metabolic rates or cause the body to burn body fat at an accelerated rate.

On a more positive note, if you were to use this product as a meal replacement shake for all three of your daily meals, you’ll probably see some reasonable weight loss over a period of 3-4 months.

Are There Any Nutribullet Lean Boost Reviews From Customers?

We have found the following Nutribullet Lean Boost review testimonials via customers on Amazon:

Out of all the protein supplements I tried out, this has got to be the very best one. I love it! It has all I need and more in a protein powder, including thermogenic ingredients and pre-biotics. I also love the fact that the one I tried doesn’t have a flavor, so I can mix it with sweet and non-sweet stuff in my macroblasts.

Taste horrible no matter what

Our Final Verdict On Nutribullet Lean Boost

To conclude our Nutribullet Lean Boost review, it’s a bit of a mixed bag – there are things that we like about it and things that we aren’t too blown away by.

It is by no means a bad meal replacement shake, we just feel that this product should contain “fat burning” ingredients for the price point – we do not believe consumers will see fast weight loss results using just the Lean Boost product alone.
