Product Info

Nutritech Casein Slow Release is a slow digesting protein shake supplying muscle building amino acids for up to 8 hours.

Lean Muscle Gains

Fitness athletes and lifters need protein for muscle gains.

They get protein mostly from meat and supplement with a shake at important times.

Each serving provides 26 grams of slow digesting protein.

Time Released Protein

When mixed Casein has a much thicker texture than Whey protein.

Casein becomes a ‘gel’ in the stomach which slows down the digestion and absorption of the protein.

The digestion process lasts between 6 – 8 hours.

Prevent Muscle Breakdown

Drinking a slow-releasing shake is beneficial to preventing muscle breakdown as it supplies the body vital amino acids during digestion.

Whey vs Casein

A whey protein shake is fast-absorbing and best used before or directly after your workouts. Casein is ideal just before bed or traveling without access to quality food.

Product Testing

To maintain the high quality standards of their products the manufacturers routinely use independent SANAS accredited laboratories for testing.

Versatile Shake

Casein is truly a versatile shake. It can be used as an almost zero-carb / fat meal replacement drink or a sugar-free protein dessert.

Nutritech Casein Slow Release offers athletes and lifters an excellent protein source when they go for an extended time without eating any food.

Not best taste - but versatile for mixes
Review by Justin  (12 February 2024)
Ok, its taste is average and a little powdery. Isn’t sweet which I think is great … here’s how I use it. I mix it with other better flavor shakes - and this Nutritech makes it double thick milkshake vibe.

My fav is mixing a 1/4 scoop of the casein to the Evolve Double Dutch Choc whey - man, it’s such a treat.

I add a 1/4 scoop to my wife’s TrueWhey Vanilla shake - which keeps her full till lunch.

I’ve tried the Nutritech as a thick pudding - didn’t have a flavor or consistency I like.
Taste Matters
Review by Chantz (14 March 2022)
For me, nutrition should be enjoyable, especially when your whey or casein might be the only treat you can look forward to. This product tastes horrible. I’ve tried adding cocoa and peanut butter and it’s still awful ????

Review by Dr. Nafario (27 May 2021)

It tastes horrible!
Decent value-for-money
Review by PD (1 November 2020)
This product was decent for its price, however, I wasn’t a fan of the taste or the terribly thick cement-like texture . I would strongly recommend putting 1.5-2 times the recommended amount of water .
Review by TC (9 October 2020)
I can't fault this...

I used,two tubs of the Strawberry flavour was really nice.

Kept me full before bed and I was not that hungry in the morning.

Really Nice

Review by Rox  (11 November 2019)
It’s awful, the taste and texture is absolutely disgusting. I’m really not impressed. Whey protein choc mint flavour is the best that this was really disappointing including the cookies and crème whey protein also has a awful taste

Best product on the market, hands down. Gotta love Nutritech!
Review by Jaco (7 August 2017)
So happy SW stocks Nutritech, now I can finally use them as my regular supplement shop again. Great Casein. Best local. Mixes easily, not too think, taste is good as well. Just not a fan of the Cookies and Cream, but the Cream Soda is great.
