Powder vs. Liquid Collagen

Despite the common belief that liquid collagen is more effective, the truth is that powdered collagen is presented in its purest form - all liquid collagen starts as powder!

Scientific studies back up the effectiveness of powdered collagen, highlighting its advantage in being minimally processed without any added ingredients. Ensuring that you get collagen in its purest form, making it easy to consume and digest.

What about Collagen tablets?

Our collagen delivers a whopping 10g per scoop, while most tablets offer only about 2-2.5g per tablet. This means you'd have to take 4 or 5 tablets a day just to match our collagen amount, which could end up costing you a lot!

Frequently Asked Questions


CollaSlim simplifies the process of reducing calories to reach your desired healthy weight. However, if you discontinue using the shakes and revert to consuming more calories than your body requires, you risk regaining the lost weight and possibly even more than before.

Instead, the aim is to adjust your intake to match your body's needs, making it easier to control your eating habits.

The University of Oxford conducted a clinical trial on this topic and found that among the individuals assessed long term results, those who followed a meal replacement program weighed less than when they started the program, up to four years later.


A single serving of CollaSlim is designed to replace one meal, and it contains 7.6 grams of sugar when mixed with almond milk, comfortably below the daily suggestion of 30g recommended by the NHS (and Diabetes UK). Furthermore, losing weight can reduce the risk of Type 2 Diabetes by half.

A significant UK research study, DiRECT, explored the effectiveness of an intensive 850 calorie diet in achieving Type 2 Diabetes remission. The trial involved liquid meal replacements for approximately 8 weeks, followed by a gradual reintroduction of food under the guidance of health professionals. At the end of the trial, researchers found that weight loss could indeed lead to Type 2 Diabetes remission. After one year, nearly half of the participants (45.6%) achieved remission. Remarkably, those who maintained their weight loss for up to two years remained in remission.


Extensive clinical trials on collagen effectiveness have shaped our supplements. As the first UK brand to introduce a multi-collagen in 2019, we're well-versed in our field.

Our supplements undergo independent lab testing and are supported by research. Trusted and embraced by thousands of customers the life changing benefits of our products speak for themselves.
