"I struggled for months to pack on solid muscle size without gaining stubborn belly fat from mass gainers and cheap whey blends. Switching to NutraBio Whey Isolate was the turning point. Getting 25g of pure isolate with zero fillers or junk carbs allowed me to build visible chest and shoulder density while keeping my waistline lean. My recovery between heavy lifting sessions is faster than ever!!" - Jayden

hey that doesn’t upset my stomach

"Changed from a cheaper whey because it always left me bloated for hours. NutraBio mixes well with cold water and the Dutch Chocolate flavour is light, not too sweet. I’ve been taking it after the gym and it feels much easier to drink. Finished my 2lb tub and just got the 5lb one 😅"

Frequently Asked
Questions

Why does NutraBio cost slightly more than standard whey protein?

Most budget protein powders use Whey Concentrate (WPC80) or hide fillers and cheap free-form aminos (glycine, taurine) behind proprietary blends to artificially inflate protein numbers. NutraBio uses 100% cold-processed Whey Protein Isolate (WPI90) with zero fillers, zero creamers, and full label disclosure. You pay strictly for pure, active protein.

Will this cause stomach discomfort or bloating?

No. Because it undergoes cold cross-flow microfiltration, unwanted fats and carbs are filtered out, leaving pure, fast-digesting protein. It absorbs rapidly and sits light on the stomach without the heavy, sluggish feeling typical of lower-grade concentrates.

How do I verify this tub is 100% pure and not amino-spiked?

NutraBio tests every single batch through independent ISO-accredited labs (Eurofins). Just visit CheckMySupps.com, enter the lot number printed on the bottom of your tub, and you can view the exact third-party lab test verifying protein purity and heavy metals safety.

How does it mix, and what liquid works best?

Water is the simplest choice, but you can also use your preferred beverage. Mix one included scoop with 5–6 ounces of liquid, then adjust the amount to achieve your desired taste and consistency. Shake or stir well.

When is the best time to take NutraBio Whey Protein Isolate?

Use it whenever it helps you reach your daily protein target. Post-workout is convenient for recovery, but it can also be taken in the morning or between meals. Consistent daily protein intake matters more than one exact time.

Is this product authentic and stocked locally in Singapore?

Yes. All NutraBio inventory is shipped fresh directly to Ultimate Sup’s Singapore warehouse and stored under climate-controlled conditions. Orders dispatch locally within 24 hours for fast 1–2 day door delivery.
