XL Nutrition XTRA Diet Whey, 20g Protein With CLA, Green Tea and L-Carnitine for Cutting

XL Nutrition XTRA Diet Whey is a protein powder specifically formulated for calorie-controlled diets and cutting phases. Each 30g serving delivers 20.3g of protein at 112 calories with 1.7g of fat, 3.3g of carbohydrates and just 2.5g of sugar. The 2kg tub provides 67 servings across 3 flavour options.

The protein blend uses five sources: whey protein concentrate, micellar casein, milk protein concentrate, whey protein isolate and soy protein isolate. This combination provides both fast-absorbing (whey isolate) and slow-releasing (casein) protein fractions, which helps with satiety between meals during a calorie deficit. Glutamine peptides are also included for recovery support.

What separates XTRA Diet Whey from standard whey is the added weight loss formula containing CLA (conjugated linoleic acid), green tea extract and L-carnitine L-tartrate. CLA is researched for supporting lean body composition. Green tea provides EGCG for thermogenic support. L-carnitine supports fatty acid transport into mitochondria. Inulin fibre adds a prebiotic component that supports gut health and contributes to feeling full.

This product suits anyone in a cutting or dieting phase who wants their protein shake to do more than just deliver macros. It provides diet-support ingredients in every serving so you do not need separate CLA or L-carnitine supplements. For a standard daily whey without diet-specific additions, XL XTRA Whey provides 21g protein at 122 calories. Contains milk, soy and gluten.

Frequently Asked Questions

What makes XTRA Diet Whey different from regular XTRA Whey?

XTRA Diet Whey uses a 5-protein slow-and-fast release blend (including micellar casein for sustained release) while XTRA Whey uses a 3-source blend focused on immediate protein delivery. Diet Whey also adds CLA, green tea extract, L-carnitine, inulin fibre and vitamin C specifically for weight management support. XTRA Whey delivers 21g protein at 122 calories. Diet Whey delivers 20.3g at 112 calories with diet-specific extras.

Does XTRA Diet Whey help with weight loss?

XTRA Diet Whey supports a weight loss plan but does not replace a calorie deficit. The added CLA, green tea and L-carnitine have research behind them for supporting fat metabolism and body composition when combined with a structured diet and exercise programme. The slower-releasing casein protein also helps with satiety, meaning you feel fuller between meals.

Is XTRA Diet Whey suitable for people with lactose issues?

XTRA Diet Whey contains multiple milk-derived proteins including whey concentrate and micellar casein. It is not lactose-free and is not suitable for people with dairy allergies. If you have mild lactose sensitivity, the whey isolate component is lower in lactose than concentrate, but the formula as a whole is not designed for lactose-free diets.
