Frequently Asked Questions
What makes The Func. Lab’s whey protein isolate different?
›
Our whey isolate is single-sourced, grass-fed, and ultra-clean — no blends, no fillers, no cheap milk powders. With over 85% protein content and added digestive enzymes, it delivers maximum protein per scoop while being easy on the gut.
How much protein is there per scoop?
›
Each 35g scoop provides 30g of high-quality protein, with >89% of calories coming from protein — one of the highest protein-to-calorie ratios on the market.
Is your whey protein isolate gut-friendly?
›
Yes. We’ve added bromelain and papain, two natural digestive enzymes, to support easier digestion and reduce bloating. Many customers report feeling light even after regular use.
Is this suitable for people with lactose intolerance?
›
Yes. Whey protein isolate contains minimal lactose and is typically well-tolerated by individuals with lactose sensitivity. However, we always recommend consulting a doctor if you’re unsure.
Is it third-party tested?
›
Yes, all our protein batches are third-party lab tested for purity, heavy metals, and protein content, ensuring safety and trust.
Can I take this protein every day?
›
Absolutely. It’s designed for daily use — whether you’re working out, trying to build muscle, recover faster, or just increase daily protein intake.
Is this protein safe during pregnancy?
›
It contains clean ingredients and no artificial additives, but please consult your doctor before use during pregnancy or breastfeeding.
Is it safe for kids?
›
Yes, in moderate quantities and as advised by a pediatrician. It’s a clean protein option with no added sugars, gums, or fillers.
Can I use this if I’m not working out?
›
Yes. Protein is an essential macronutrient — your body needs it for muscle repair, immunity, hormones, and overall health, even if you’re not exercising.
How is whey isolate different from concentrate?
›
Whey isolate is more refined — it contains more protein (90%+), less lactose, and minimal fat and carbs compared to concentrate. It’s ideal for people looking for a cleaner, faster-digesting protein source.
When should I take whey isolate?
›
Post-workout is ideal for muscle recovery. But it can be taken anytime — morning, between meals, or even before bed — depending on your protein goals.
Do you use any added sugar or artificial sweeteners?
›
No. We only use monk fruit and stevia in flavored variants — both are plant-based and natural. Our unflavored version has no sweeteners at all.
What’s the amino acid profile like?
›
Each serving provides 14–15g of EAAs, including 6.3–6.9g of BCAAs, essential for muscle repair, strength, and recovery.
What’s the protein-to-calorie ratio?
›
- Vanilla: 30g protein / 129.6 kcal → 89.7%
- Chocolate: 29g protein / 130.9 kcal → 88.2%
- Coffee: 30g protein / 130 kcal → 89.2%
- Unflavored: 30g protein / 131 kcal → 87.9%
Do you use gums, thickeners, or emulsifiers?

Never. No gums, no maltodextrin as filler, no emulsifiers. Just protein, flavor, and function — nothing extra.
