Why choose Emrald Labs Iso Zero whey protein isolate

Iso Zero is a premium whey protein isolate, built for anyone chasing maximum protein with the least possible fat, carbs and sugar. Emrald Labs uses high-quality whey protein isolate as the base, so you get fast-absorbing protein that supports muscle recovery, lean muscle growth and daily performance, with no unnecessary fillers or extra calories.

That clean nutrition profile makes Iso Zero ideal if you are in a calorie deficit, holding a lean physique, or just want a high-quality protein to back your training and recovery. Iso Zero digests fast and mixes smoothly, so a shake works after training, between meals, or any time you need more protein in your day.

What Iso Zero helps with

• Recovery after training: fast-absorbing whey isolate to support muscle repair.
• Lean muscle growth: over 2 g of leucine per serve, the amino acid most linked to building muscle.
• Cutting and calorie control: 110 calories with less than 1 g of fat and 1.4 g of sugar per serve.
• Hitting your protein target: an easy extra 22 g or so of protein, any time of day.

Ingredients

Whey protein isolate (contains milk), flavours, cookie crumbs (gluten-free flours from tapioca and chickpea, sugar, rice bran oil, cocoa butter, cocoa powder, raising agent, salt), L-glutamine, medium chain triglyceride (MCT) oil powder, thickeners (xanthan gum, guar gum), flavour enhancer (sodium chloride), anticaking agent (silicon dioxide), branched chain amino acids (L-leucine, L-isoleucine, L-valine) and sweetener (sucralose). This list is for Cookie Caramel. Other flavours swap the cookie crumbs for cocoa, cinnamon or other flavours.

What is whey protein isolate?

Whey protein isolate (WPI) is whey that has been filtered more than regular whey concentrate. The extra filtering removes most of the fat, carbs and lactose, so more of each scoop is protein. Iso Zero uses an instant WPI that is 90% protein, which helps the powder mix smoothly without clumps.

Iso Zero vs regular whey

• Fat and carbs: Iso Zero has less than 1 g of fat and about 2.4 g of carbs per serve. A whey concentrate usually has more of both.
• Lactose: isolate is filtered to remove most lactose, so isolate often sits better if regular whey makes you bloated. Iso Zero still contains milk.
• Price: isolate costs a little more than concentrate. If you don't mind a few more carbs, Emrald Labs 100% Whey Protein is the lower-cost option.

7 flavours

Banana, Chocolate, Churro, Cookie Caramel, Strawberry, Vanilla and White Choc Macadamia. Churro and Cookie Caramel are the dessert-style picks, and Churro is a favourite for baking. Chocolate, Strawberry and Vanilla also come in the 2 kg tub. Not sure which to choose? Iso Zero is covered by our Love the Taste Guarantee. Try up to 5 serves within 30 days.

Sizes and value

• 810 g (27 serves): $119.95, about $4.44 a serve.

How to take Iso Zero

Mix 1 serve (30 g) with 250 to 350 ml of cold water and shake well. Have one serve after training. For enhanced recovery, have another serve between meals. You can also mix Iso Zero with milk for a creamier shake, or add a scoop to smoothies, oats, pancakes or baking.

Who should take Iso Zero?

Iso Zero is a good fit for people on a cut or watching their calories, lifters who want a lean protein after training, anyone who finds regular whey heavy on the stomach, and people who like dessert-style flavours without the extra sugar.

Allergens and side effects

Iso Zero contains milk. Check each flavour's label for other allergens, such as soy lecithin in some flavours. If you are new to protein shakes, start with one serve a day and drink plenty of water. People with a milk allergy should not use Iso Zero.
