Challenger Casein

What is Challenger Casein?

• Challenger Casein is a milk‑derived slow‑digesting protein powder (milk‑casein blend / micellar casein) rather than a fast whey protein. 

• It’s marketed as a supplement that delivers a sustained release of amino acids — useful between meals or before bedtime — to support muscle repair/maintenance during long periods without eating (e.g. overnight). 

• The product is often sold in smaller tubs (for example 900 g for 30 servings) in available listings. 

Typical Nutrition & Serving Info:

From a commercial listing of Challenger Casein: 

• Protein per serving: ~ 24 g (or close, depending on serving size). 

• The casein is described as “milk‑casein blend” — coming from milk protein isolate and micellar casein. 

• The powder is mixed with water or skimmed milk. Recommended mixing: 1 scoop with 120–170 ml; or 2 scoops with 250–350 ml depending on preference. 

• Use timings often recommended: between main meals, or at times when you won’t eat for a while (e.g. before sleep) for sustained amino‑acid delivery.

What It’s Supposed to Do / Typical Uses:

Challenger Casein claims to provide the following benefits:

• Slow, steady release of amino acids — helpful when you go long periods between meals or overnight. 

• Support muscle recovery, maintenance and growth — especially beneficial in periods without immediate nutrient intake (e.g. sleep, long breaks). 

• Help prevent muscle breakdown (catabolism) when you’re not eating, by supplying a steady “protein stream.” 

• Provide a convenient, easy‑to‑use protein source, which can complement dietary protein intake especially if whole‑food protein is insufficient. 

Things to Keep in Mind / What to Verify!

• Casein digests slowly — that’s the point. But if you need fast protein delivery (e.g. immediately post‑workout), whey‑based supplements are usually more effective. 

• Because protein supplements (whey or casein) are optional complements — their benefit depends heavily on overall diet, training, and total daily protein intake. 

• Make sure to buy from reliable vendors — check packaging, expiry date, and batch code (as many listings for Challenger products state) to ensure authenticity. 

• If you’re lactose‑intolerant or dairy-sensitive, even casein (milk‑derived) may cause digestive discomfort — something to review before regular use. (This is general for dairy‑based proteins.)

What Versions Are Available / Typical Packaging:

• A common available version is Challenger Casein 900 g (≈ 30 servings). 

• Flavor typically Chocolate (and maybe other flavors depending on seller).
