A MAK-Honest Review of M-Casein

Supplement Type: Protein

Improve your overnight recovery with this amazing blend of naturally occurring muscle sparing amino acids. M-Casein is the perfect blend of slow release protein to ensure you're utilising the right amount of protein at the right time whilst you sleep.

When to take M-Casein?

Mix 40g (1¬Ĺ SCOOPS) with 350ml ‚Äď 400ml of cold water, low fat milk, full cream milk or soymilk in a shaker or blender.

Take 1-2 times daily when a sustained protein release is required. Best times for use are before bed or between meals. Not recommended for use immediately after training.

How does M-Casein work? Pros?

Natural Muscle Protection:¬†High levels of threonine, glutamine and arginine, the ‚Äėglucogenic‚Äô amino acids which lend themselves to glucose production during exercise and may prevent muscle breakdown.

Slowly Digested: Quality M-Casein proteins for sustained and efficient digestion for up to 7 hours, making it perfect for use before sleep or between infrequent meals.

Increased Amino Acid Absorption: The slow digestion rate provided by M-Casein helps improve the absorption rate of casein’s unique amino acids, including muscle sparing glutamine, threonine and arginine.

Prolonged Positive Nitrogen Balance: M-Casein’s unique gelling properties during digestion help slow the release of amino acids prolonging the body’s state of Positive Nitrogen Balance (PNB) for maximal muscle growth & recovery.

Naturally High in L-Glutamine: 20% of the amino acids in M-Casein are Glutamine to help spare muscle during training.

Naturally High in Calcium & Phosphorus: Two synergistic minerals that are key to athletic performance.

Calcium: Is essential for efficient muscle contractions.

Phosphorus: Can help decrease lactic acid levels during training. Phosphorus also produces high energy molecules such as ATP and Creatine Phosphate. These molecules power muscle contractions during weight training.

No Aspartame: Sweetened with sucralose for a pleasant taste and no unwanted compounds.

No Fillers or Stabilisers: Just 30g of high quality sustained release protein in each serve.

No Gluten: No cheap glutamine peptides derived from hydrolysed wheat or low quality wheat proteins making it suitable for coeliacs and people with wheat allergies.

Rich Dessert Texture:¬†M-Casein¬†is naturally thicker than WPI and mixes into a thicker, more dessert-like consistency. It can be used to make protein ‚Äėpudding‚Äô by adding half the recommended amount of liquid, or into a full bodied shake by using the recommended amount.

M-Casein: Is designed to promote muscle growth and recovery by keeping the body in a positive nitrogen balance between meals and especially overnight.
