THP Ultimate Casein Protein, 23.3g Slow-Release Protein for an Evening Shake

The Health Project Ultimate Casein Protein is a slow-release pre-bed protein built for trainees who want sustained amino acid delivery overnight. Each 30g serving delivers 23.3g of protein at 106 calories, with 0.3g of fat, 2.3g of carbohydrates and 2.3g of sugars. The 2kg tub provides 67 servings.

The protein source is 100% micellar casein - the slower-digesting fraction of milk protein that forms a gel in the stomach and releases amino acids over a 4-6 hour window. This makes it suited to an evening shake before bed. The 23.3g protein dose sits in the standard daily protein-shake range, and the 106 calorie macro keeps the pre-bed shake from being a meal-replacement load.

What separates casein from whey is the digestion speed. Whey digests quickly, so it suits daytime use better than overnight. Casein releases amino acids steadily for several hours, making it the textbook pre-bed protein for trainees who can't or don't want to wake for a middle-of-the-night protein meal. Most people only need one daily protein shake, and casein is an option for those who want a slower-digesting one in the evening.

Ultimate Casein suits anyone who wants a slow-digesting evening shake and anyone who finds whey shakes don't keep them full through to morning. Not the right pick as a quick daytime shake (whey digests faster) or as your only daily protein. Contains milk.

Frequently Asked Questions

What is the difference between casein and whey protein?

Both come from milk, but they digest at different speeds. Whey is fast-digesting, which suits daytime shakes. Casein forms a gel in the stomach and releases amino acids slowly over several hours. THP Casein provides 23.3g protein per serving, similar to the 21.3g in THP Ultimate Whey, but the sustained delivery makes casein better for overnight use or long fasting gaps.

Can I use THP Casein as my only protein powder?

You can, but most people benefit from having both whey and casein. Whey is the quicker-digesting option for daytime shakes. Casein is better before bed or during long gaps between meals. If you can only buy one, whey is generally more versatile. If you are adding a second protein to your routine, casein before bed is the most valuable addition.

How do I mix THP Casein into a thicker pudding texture?

Use less liquid than you would for a whey shake. Mix one scoop with 150 to 200ml of water or milk rather than the usual 250 to 300ml. Stir with a spoon rather than shaking, and let it sit in the fridge for 10 to 15 minutes. The micellar casein thickens naturally as it absorbs liquid. Some people add a small amount of Greek yoghurt or peanut butter to make it even more like a dessert.
