I feel drained all the time...

We know the feeling. 

But it doesn’t have to be that way. In today’s increasingly busy world, it can sometimes feel like there are never enough hours in the day. Especially if you’re someone who wants to push themselves further and get the most out of life. 

Say goodbye to simply accepting the days of running on empty, and hello to a new lease of life. Formulated by leading nutritionists, The Fit Protein is the perfect post-workout recovery aid, or even just a great snack for any time of day to give you that extra push. It comes in a couple of different flavours all of which taste bloody amazing. Because you shouldn’t have to compromise on feeling your best.

Is this good for post-workout recovery?

All our protein blends are perfect to help for recovery and repair but The Fit Protein in particular contains a selection of ingredients including important electrolytes that are lost when you sweat. It’s the ideal protein blend for anyone who is working out hard, doing a lot of aerobic activity or needs help raising their energy levels.

How often should I take it?

At Innermost we believe in a food-first approach. For that reason, we recommend taking The Fit Protein as part of a balanced diet ideally post-workout or 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 Fit 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 Fit Protein provides a complete amino acid profile per serving as follows: Leucine (3.0g), Isoleucine (1.9g), Valine (1.9g), Alanine (1.5g), Arginine (0.7g), Aspartic Acid (3.4g), Cystine (0.7g), Glutamic Acid (5.4g), Glycine (0.4g), Histidine (0.5g), Lysine (2.9g), Methionine (0.6g), Phenylalanine (0.9g), Proline (1.6g), Serine (1.4g), Threonine (2.0g), Tryptophan (0.4g), Tyrosine (0.8g).

Will The Fit 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.

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.

Awarded Best Protein in the Men's Health Sport Nutrition Awards. Recovery is half the battle when it comes to working towards body goals. That's why Innermost's blend spoons out more than just protein - dried coconut water to replenish electrolytes, rhodiola root to combat stress, and magnesium, a nutrient that supports muscle function. It's a Men's Health office favourite.

Science over hype

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 boost energy and vitality, support muscle repair and speed up recovery, we're confident that you’ll thank us later.

Per Serving:


Vegan Protein (31g): The building block of bones, muscles, hair, skin, and nails, this blend of plant-based pea and brown rice protein contains all the essential amino acids your body needs for repair, recovery and development. References > 12.


Cocomineral (1g): Coconut water is an increasingly popular post-workout rehydration aid that is touted as being a better alternative than water. Cocomineral, which is powdered coconut water, contains high levels of potassium, a key electrolyte lost through sweating when exercising, to help combat tiredness and rebalance energy levels. References > 3, 4. 


Maca (1g): Reduces effects of physical and mental stress, and increases energy and libido. Grown for more than 2,000 years in the highest mountains of Peru, maca has recently found widespread popularity as an adaptogen. These are a select group of natural ingredients that support the body's ability to deal with stress. References > 5, 6.


Magnesium (250mg, 67%*): An important mineral that contributes to electrolyte balance and normal energy-yielding metabolism. It is required to regulate blood pressure, keep bones strong, and the heart rhythm steady. Adults who are deficient in magnesium are more likely to have elevated inflammation markers, which in turn, has been associated with serious health conditions. References > 7, 8.

Rhodiola Rosea

Rhodiola Root (250mg): A nootropic powerhouse, this flowering plant has mounting research to support its claims to reducing the effects of physical exhaustion that can result in fatigue, stress and 'burnout'. Increasingly used by people to help them cope with heavy workloads, headaches, and improve mood. References > 9, 10.

Pink Himalayan Sea Salt

Pink Himalayan Sea Salt (150mg): Rock salt from the Punjab region of India. Contains the same 84 trace minerals and elements found in the human body including calcium, potassium, and magnesium. Because of its unique cellular structure, the minerals it contains exist in colloidal form, which means that they are small enough for our cells to easily absorb. References > 11.

*%NRV (Nutrient Reference Values) are guidelines on daily amounts of vitamins and minerals to be consumed to maintain a healthy diet.

Why it's special


Protein is a macronutrient that’s necessary for healthy muscles, skin, nails and bones. A combination of brown rice protein and pea protein makes up the perfect amino acid profile, allowing your body to repair, recover and develop at an optimal level.


Maca and rhodiola root contain properties that reduce physical stress, increase endurance and decrease fatigue. They are a part of a select group of ingredients that also support focus and performance. Nootropics have many other helpful effects to improve your fitness, such as boosting motivation and energy.


Cocomineral, magnesium and pink Himalayan sea salt are ingredients that help hydrate your body and support energy production. They also balance electrolytes, which allows your muscles and blood pressure to function properly. Keeping these key nutrients in check not only optimises the body during exercise, but throughout recovery.

When should I use the product?

Anytime during the day as a healthy snack to meet your protein needs! However, you can also use it to make a quick nutritious shake or smoothie anytime of the day, or in your porridge or oatmeal to top up your daily protein intake. The protein blend is also versatile enough to bake into high-protein snacks.

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 or so. 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 either creamy vanilla or smooth chocolate. 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 and cocoa, 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.

Another great product!

Great taste as all the products I tried and easy to drink. They are helping me with the health protein to get the energy I need!

Best protein ever!

I used to get the health protein and I didn't think vegan protein could get any better but then I tried the new vegan fit protein. The texture is so smooth and the taste is so great, no chalkiness or weird aftertaste. It is the only protein I can drink and enjoy just mixed with water. I have both flavours but I love the vanilla one slightly more because of the vanilla bean, however both taste great. I could never be without it.

Amazing product and service

Love the fit protein, it gives me a boost of energy and helps me perform during my workout. I’m always so impressed with the service and delivery from innermost, ordered my protein at 4pm on a Friday and it was with me by 11am on Saturday morning! Always reliable and great products
