This product is vegetarian, cruelty free, gluten free, soy free, halal, suitable for kosher diets, non-GMO, and free from most major allergens. Furthermore, the product contains no artificial flavours, fillers, bulking agents or colours.

The protein in this product is sourced from whey (milk); a complete source of protein containing all the amino acids your body needs. We've added guar gum, which is a GMO-free, gluten-free, natural fibre that comes from the guar bean to give our shakes a creamy texture. We use sunflower lecithin instead of soy lecithin, which is the only kind of lecithin that can be obtained raw and chemical-free using a cold press system similar to that used with olive oil. We also add some sweetness to the product by adding a tiny bit of sucralose, which is the most widely tested low-calorie sweetener and approved by all food standard agencies in the world.

Need some help getting leaner?

 
We understand.

That's why we created The Lean Protein. Just like you, we were sick of being marketed products that told us to stop eating, or simply didn't work. The first thing to consider is why do you want to lose weight and will it benefit your health? Don’t fall into the trap of equating weight-loss to happiness.

That said, a recent survey found that almost half of adults have tried to lose weight in the last year, so we know this is one of the biggest concerns people had. If you’re in that camp, we understand. It’s ok to want to lose fat, albeit in a healthy, controlled way. No fad diets, no restrictions, no nonsense.

Formulated by leading nutritionists, The Lean Protein is a genuinely delicious protein powder that is the perfect partner to help you get lean, tone up, and lose body fat, alongside a sensible diet and workout routine. Because your goals are achievable.

Is this a meal replacement?

Our protein blends are not designed to be meal replacements, but instead as a healthy addition to a balanced diet. They’re great as a post-workout recovery aid, midday refuel - or just whenever you’re feeling peckish! If you’re looking for something filling that keeps you going until your next meal, consider blending up a protein smoothie with some healthy fruit and vegetables. Sign-up to our email newsletter and we’ll send over some recipes.

How often should I take it?

At Innermost we believe in a food-first approach. For that reason, we recommend taking The Lean Protein as part of a balanced diet any time during your day as a healthy snack to meet your protein needs. You should always aim to meet most of your nutrient needs through the food you eat but having a high-quality protein powder like The Lean Protein, which contains additional ingredients to support your goals can be an efficient way to help fill gaps in your diet.

Does it have a complete amino acid profile?

Yes! The Lean Protein provides a complete amino acid profile per serving as follows: Leucine (2.9g), Isoleucine (1.9g), Valine (1.8g), Alanine (1.6g), Arginine (0.7g), Aspartic Acid (3.4g), Cystine (0.7g), Glutamine (5.5g), Glycine (0.4g), Histidine (0.5g), Lysine (2.8g), Methionine (0.7g), Phenylalanine (0.9g), Proline (1.7g), Serine (1.5g), Threonine (2.0g), Tryptophan (0.4g), Tyrosine (0.7g). 

Will The Lean Protein make me bulky?

No! ‘Bulkiness’ is a result of continuous muscle training, usually employing heavy weights and a specific high-calorie diet, and can take a lot of effort and time. In reality, protein keeps you fuller for longer so it can actually help you get more toned and defined alongside a sensible diet and physical activity, should that be your goal.

Why should I believe this product will work?

All our products have been formulated by expert nutritionists using science-backed research supported by peer-reviewed clinical trials. You can read some of these clinical studies by clicking here. Our products work because we focus on the following things above all else - the ingredients we use, the quality of these ingredients, their concentrations and how well they're absorbed by your body. Our unwavering commitment to that approach means what you get are the highest quality, cleanest supplements in the world today - without any BS.

Nutrient heavy and evidence-based products, rather than pure fluff. The Lean Protein features inulin, a substance linked to lower levels of visceral fat (the killer kind...), along with high quality protein to aid muscle repair and recovery, yerba mate for energy, and pomegranate and bilberries for an antioxidant rush. Basically, a research based post-workout beverage of dreams.

Our ingredients

 
With so many “miracle” ingredients being touted out there, it can be hard to know what really works. We believe evidence-based ingredients are the best way to better health. With decades of clinical studies behind these active ingredients showing how they can help reduce cravings, encourage sustainable fat-loss, and speed up recovery, we're confident that you’ll thank us later.

Inulin

Inulin (1g): Advanced research in weight management emphasises recognising the importance of our gut as a metabolic organ. Inulin is a prebiotic fibre that encourages growth of good gut bacteria linked to lower levels of fat. References > 34.

 

Acetyl L-Carnitine

Acetyl L-Carnitine (750mg): A non-essential amino acid necessary for transporting fat to the body’s power-generating mitochondria. Without it, we wouldn’t be able to use fat effectively as a source of energy, which could result in the body having to break down muscle instead. References > 56.

Pomegranates (500mg): This fruit has sparked interest in recent years largely due to its punicalagin and ellagic acid content. These compounds are retained in the gut where they encourage the growth of good gut bacteria linked to lower levels of fat. References > 78.

 

Yerba Mate

Yerba Mate (500mg): Dried leaves of an evergreen holly tree native to South America. An incredibly high antioxidant content and has been shown to have possible effects in the area of weight management, which could be due to it helping delay intestinal absorption of dietary fat. References > 910.

Why it's special

Protein

Protein is a macronutrient that’s necessary for healthy muscles, skin, nails and bones. Whey protein concentrate and isolate are loaded with the essential amino acids that your body needs to function efficiently. As a high-quality source of protein, whey also lowers blood pressure, decreases inflammation and reduces cravings.

Bioactives

Pomegranates, yerba mate, bilberries and inulin are active ingredients that provide wide-reaching health benefits. Inulin and pomegranates have properties that encourage the growth of good bacteria, while bilberries and yerba mate are rich in antioxidants. These bioactives have been shown to positively affect weight management through their different properties.

Functional Ingredients

Acetyl l-carnitine is functional for both your physical and mental health. By transporting fatty acids to the mitochondria, the supplement is effective when it comes to improving memory, increasing endurance and reducing fatigue. It allows your body to burn fat for energy, so that your workouts are optimised for muscle health and development.

When should I use the product?

Our protein blends are the perfect choice for a post-workout recovery drink or anytime during the day as a healthy snack to meet your protein needs! They can be used to make a quick nutritious shake or smoothie any time of the day, or mixed into your morning porridge or oatmeal to top up your daily protein intake. This protein blend is also versatile enough to bake into high-protein snacks, and can be consumed daily or as desired.

How long will the product last?

This depends on how often you use the product. Typically a pouch of our protein blends will last around a month. If you're using it every day and also adding it to porridge and smoothies, you may run out sooner. We have a subscription option, which saves you money and ensures you'll never run out.

What does it taste like?

All our protein blends come in creamy vanilla, smooth chocolate or summer strawberry flavours. We spent months perfecting the flavour systems to create our own completely custom flavours that you won't get anywhere else. The flavours are characterised by complex layers of vanilla, cocoa and strawberry, with subtle notes of caramel and biscuit. We only use natural flavours and you can adjust the sweetness down or up by using more or less liquid.

What sort of testing do you do?

We go over and above to ensure you get the best quality and safest products possible. We only use ingredients that have a visible supply chain, and our manufacturing facilities are approved to the highest regulatory standards. Once we receive ingredients, we batch test every single one before it gets approval to go into the manufacturing process. That isn’t technically an official requirement but it’s something that we think should be.

Changing me

I am a typical guy who loves to eat bad and drink too much and hates exercising. Then I have a health scare, got to get fit and cut the bad stuff out. I have been doing ok but needed a good protein not easy to find. I have tried them all and I have quite a collection of them and then I discovered innermost this stuff is the bomb love it. No sticky horrible mess and horrible taste it’s smooth, tasty and makes me feel great. It also arrives so quickly even during lockdown. I am using the lean protein and have noticed changes to my body In a good way. Definitely give innermost a go and this is coming from a guy who said none of that stuff works. Thanks.
