Proudly Made In The UK

So Body Co was the first British company to produce a multi-collagen supplement. Maintaining our ethos for innovation we now introduce another first; CollaSlim, a meal replacement shake combined with collagen.

We remain a small but dedicated team based in Maidstone, Kent.

QUESTIONS? Our covid safe working practices mean we are often working out of the office which means we can't always get to the phone. You can try calling us on 01622 946 370 but the best way is to reach us with any questions here.

Can I take CollaSlim along with your Peptigen multi-collagen product?

We recommend you take 10g of collagen per day. CollaSlim contains 5g per serving. So if you are replacing two meals per day then there's no need for any additional collagen. However, if you are taking one CollaSlim shake each day then yes you might want to top up with a half measure of Peptigen too.

Is CollaSlim suitable for type 2 diabetics?

Yes, one serving of CollaSlim is designed to replace a single meal, the NHS (and Diabetes UK) recommend an adult is limited to around 30g sugar per day. A serving of CollaSlim with almond milk includes 7.6 grams of sugar. So comfortably under one third of the daily suggestion.

In fact losing weight can reduce your risk of Type 2 Diabetes by half.

A major UK research study (DiRECT) investigated an intensive 850 calorie diet to see if weight loss could put Type 2 Diabetes into remission. This trial used liquid meal replacements for around 8 weeks. After 8 weeks, they gradually re-introduced food with the support of health professionals. At the end of the trial, the researchers found that weight loss can put Type 2 Diabetes into remission. After one year of the programme, almost half of the participants (45.6%) were in remission. Better still, people who kept their weight off for up to
two years were able to stay in remission.

But don't you just put the weight back on after?

CollaSlim makes it easy to create a calorie deficit to reach a healthy target. Once that has been achieved if one goes back to a diet that creates a calorie excess then yes of course you will gain weight again.
Instead the goal is to make some changes to ensure the bodies calorific intake is aligned with its needs.
The University of Oxford did some research on this and found that among the studies that assessed long term results it showed that people who followed a meal replacement program weighed less than when they started the programme up to four years later.

Is CollaSlim gluten free?

Yes, CollaSlim is gluten free

Does CollaSlim contain shellfish?

No, the marine collagen content is sourced from a freshwater fish and so there is no shellfish in CollaSlim.

Is CollaSlim suitable for a keto diet?

Yes, if you're aiming for a moderate carb target of 20-50 grams per day then this should sit comfortably within your regime. CollaSlim provides a complete meal for 10g of carbs.

† Meal replacement for weight control: Substituting one daily meal of an energy restricted diet with a meal replacement contributes to the maintenance of weight after weight loss. Meal replacement for weight control: Substituting two daily meals of an energy restricted diet with meal replacements contributes to weight loss.

Estimated 8lb weight loss based on a healthy loss of 2lb per week. This should be realistic for most people providing they follow the recommended plan however results may vary and depend on your levels activity, metabolic rates and any medications you may be taking.
