Quick answers
Is this right for you?
Who is it for?
The Health Project Ultimate Casein Protein is designed for people who want sustained protein release, especially overnight. Casein digests slowly, making it ideal as a bedtime shake or for anyone who goes long stretches between meals and wants to keep muscle protein synthesis ticking over.
What can you expect?
A thick, slow-digesting shake that keeps you feeling full for longer. Casein forms a gel in the stomach, releasing amino acids steadily over several hours. This makes it less ideal immediately post-workout but excellent for sustained recovery windows. With 77.67g of protein per 100g (around 23g per 30g serving), The Health Project Ultimate Casein Protein sits in a solid mid-range for a casein product.
What else do you need to know?
The Health Project Ultimate Casein Protein is a casein protein powder made by The Health Project. It comes in 2kg sizes. Every price on WheyWise is read from the retailer’s own page and re-checked daily and sorted by cost per 100g, so you can see both the cheapest option and how current it is. All links to Amazon and retailer sites are affiliate links - this is how WheyWise stays free.
