Product Overview

Micelle XL™ is a protein manufactured using a unique ultrafiltration process, resulting in the formation of extra-large micelles. The outcome of this is a prolonged release of amino acids. This makes Micelle XL™ the perfect protein companion for use as a night time supplement. With 21g of protein per serving and just 0.5g of fat, Micelle XL™ is suitable for a range of training plans and goals. With 4.5g of BCAAs and 4.5g of glutamine per serving, Micelle XL™ provides a plentiful supply of the key amino acids.

Micelle XL™ has been designed to provide a tapered release of amino acids to the muscle tissue, at a rate never seen before. Offering a constant stream of protein to the system, whether it be at night or between meals, choose Micelle XL™ as the premium casein.

Micelle XL™ is ideal for anyone engaged in a physically exerting training plan where getting the right dietary balance is absolutely essential. It's also an excellent supplement to help increase daily protein intake. As a dietary supplement we recommend consuming before bed or between meals, 2-3 times per day.

Please note that the labelling on this product is provided in English as a minimum. French, Italian, German, Spanish, Danish, Swedish and Finnish may also be present on a product by product basis.

Popping the Cherry on the XL!









Thought i'd pop the cherry on this product...the price premium at first puts you off, but i've used pretty much every protein powder going, and sometimes there's a trade off with quality, benefits, absorption; so wanted to see what you got for your money. I was always a big whey user, but in recent years i've tended to favor more slow release proteins, your body can only absorb so much at once, your body gets stronger at rest, and most successful bodybuilders/athletes use intermittent protein fasting, so the tapered release of Micellar Caesin supports this, without having to carry around a tin of John Wests finest, or looking like there's a gun in your pocket! They estimate traditional Micellar Caesin releases 7-8hrs; my first thoughts with the XL version is that it definitely absorbs slower, it's hard to tell how much, but I think it probably extends the release by about 2hrs, and with that your body should theoretically be absorbing more of the protein as well. Protein is 7 times less likely to be converted to fat than carbs/fat; in most cases the body will expel it as urine unless it needs the glycogen; but basically with this type of anti catabolic product, it is definitely a winner for those trying to diet / maintain muscle or recover from long training sessions. The mixability is really clean, no foam like with the standard caesin, my only quibble was the Strawberry Cream flavor was a bit mild/neutral; I ended up sticking some flav drops on top; but apart from that i'd recommend; if you can afford the extra I think it's worth it.
