No nasties

Forget aggressive laxatives and toxic meal replacements. Our approach to weight-loss is natural in the sense that it employs ingredients found in nature that are proven by science to aid healthy weight-loss.

A holistic approach

At Innermost, we know that weight-loss is a whole lot more than diet. Our products span the whole spectrum of wellness whilst helping you to achieve your goals, so you can expect better sleep, more energy and exercise recovery too.

Science backed, results driven

Every ingredient we choose to add is grounded in scientific evidence that it does what we want the product to do. And we're constantly striving to make improvements based on any new studies.

Great tasting

Say goodbye to depressing, tasteless diets. Our products are the best tasting around. You'll probably be coming back for seconds. Check out our blog for ways to enjoy.

All of our products are designed to be consumed as part of a healthy, balanced diet and are absolutely not a quick fix for bad habits! To get the most effective results, we recommend keeping a consistent exercise routine and prioritising healthy, nutritious foods alongside your Innermost weight-loss products. From there, you should be able to start seeing results in as little as a couple of weeks.

We have a free health consultation here which can help you work it out! It will take less than 5 minutes, and offers tailored product recommendations based on your goals.

As with all nutritional supplements, it’s always best to speak with your doctor first if you're pregnant or breastfeeding as they’ll have more knowledge on your individual circumstances.

Not unless you want it to! ‘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.

Typically most people consume a protein shake post-workout but you can definitely have more than one shake a day. For instance, in the morning before your workout or as a healthy nutritious afternoon snack to keep you going before your next meal.

Our protein blends are packed with functional superfoods so it's not just about the benefits of the protein that you're getting. Depending on the Innermost blend you choose, you could replenish your body with important nutrients lost during your day, reduce inflammation, provide energy for your workout, strengthen your immune system or help encourage fat-loss.

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.
