What Is Myprotein Impact Whey Protein?

Myprotein Impact Whey Protein is a whey concentrate-based powder delivering ~21–23g of protein per 25g serving, with around 4.5g of BCAAs and 3.5g of glutamine per serve. It's produced from fresh British milk, cold-processed to preserve native whey fractions, and offered in over 50 flavours from classic Chocolate Brownie to Salted Caramel.

Unlike whey isolates (which are 90%+ protein by weight), Impact Whey Protein is a concentrate sitting at approximately 80% protein content. That distinction matters — and we'll unpack exactly when you should choose each.

Impact Whey Protein vs Impact Whey Isolate: Which Should You Choose?

This is the most common question we get at Ultimate Sup. Here's a concise breakdown:

Feature	Impact Whey Protein	Impact Whey Isolate
Protein per serving	~21g	~23g
Protein % by weight	~80%	~90%+
Lactose content	Moderate	Minimal
Fat content	~1.9g	<1g
Filtration process	Micro-filtered	Cross-flow ultrafiltered
Best for	Value, bulking, general use	Cutting, lactose-sensitive
Price (SG)	More affordable	Premium

Our recommendation: If you're lactose-tolerant and focused on volume/value, stick with Impact Whey Protein. If you experience bloating or are in a strict cut, upgrade to the Myprotein Impact Whey Isolate.

Impact Whey Protein Review: Taste & Mixability

Our team tested 6 flavours available at Ultimate Sup Singapore:

• Natural Chocolate — Rich, not overly sweet. Mixes clean with 250ml water.
• Vanilla — Creamy, excellent base for smoothies.
• Salted Caramel — Standout flavour; sweet-savoury balance.
• Strawberry Cream — Noticeably sweeter; pairs well with oat milk.
• Unflavoured — Neutral, slightly milky. Best for cooking.
• Banana — Authentic, not artificial-tasting.

Mixability across all flavours scores 9/10 — minimal clumping in a standard shaker. In Singapore's heat, we recommend mixing with cold water or ice to improve palatability post-workout.

Impact Whey Isolate: Singapore's Purest Whey Option

For athletes on an aggressive cut or those with dairy sensitivity, the Myprotein Impact Whey Isolate is a step up. At 23g protein per 25g serving, it's one of the purest whey sources available in Singapore today.

Key advantages of Impact Whey Isolate: - Lower lactose — Cross-flow microfiltration removes most lactose residue - Higher protein density — Ideal for IIFYM (If It Fits Your Macros) practitioners - Faster absorption — Slightly faster amino acid delivery than concentrate, though differences are marginal per the Journal of the International Society of Sports Nutrition (ISSN Position Stand, 2017)

Should You Stack Impact Whey With Creatine?

Yes — and here's why. Whey protein and creatine address completely different physiological pathways:

• Whey protein supplies amino acids (specifically leucine) that activate mTOR, the primary anabolic signalling pathway for muscle protein synthesis.
• Creatine replenishes phosphocreatine stores in muscles, directly enhancing high-intensity output capacity, force production, and cellular hydration.

Research from Examine.com's comprehensive creatine meta-analysis confirms that combining creatine with protein training produces greater lean mass gains than either supplement alone.

Recommended stack at Ultimate Sup: - Myprotein Impact Whey Protein 2.5kg — post-workout - MuscleTech Platinum 100% Creatine 400g — 3–5g daily, any time

This pairing is Ultimate Sup's most recommended muscle-building stack for Singaporean gym-goers.

How to Use Impact Whey Protein for Best Results in Singapore

Given Singapore's tropical climate (28–34°C year-round), protein timing and hydration strategy matter more than in temperate climates:

1. Post-workout window (0–60 min): Mix 1 scoop (25g) with 250–300ml cold water. Leucine threshold (~2.5–3g) is met in a single scoop to trigger MPS.
2. Morning meal amplifier: Blend with banana, oats, and 200ml oat milk for a complete breakfast with ~35g protein.
3. Pre-sleep (optional): Layer with a casein source or combine with Greek yoghurt for sustained amino acid delivery through Singapore's humid nights.
4. Total daily target: Consume 1.6–2.2g protein per kg body weight, as outlined in the ISSN's protein position stand.

Frequently Asked Questions

Is Myprotein Impact Whey Protein good for Singapore's climate?

Yes. Impact Whey mixes easily with cold water, making it practical for Singapore's heat. The powder is stable at room temperature and maintains potency throughout our tropical conditions. We recommend refrigerating open tubs to maintain freshness.

How much protein is in Myprotein Impact Whey per serving?

21g of protein per 25g serving (approximately 84% protein by weight). This puts it firmly in the "high-protein" category for a whey concentrate.

Is Impact Whey Protein suitable for lactose intolerant users in Singapore?

Impact Whey Protein contains moderate lactose (it's a concentrate). If you experience bloating, switch to Impact Whey Isolate which has undergone additional filtration to remove most lactose.

Can I use Impact Whey Protein for weight loss?

Yes. At ~100 kcal per serving with 21g protein, it supports satiety and muscle preservation during a calorie deficit. Pair with Impact Diet Whey if you want an even lower-calorie option.

What is the difference between Impact Whey Protein and creatine?

They work through entirely different mechanisms. Whey supplies protein/amino acids for muscle building. Creatine (like MuscleTech Platinum Creatine) replenishes energy stores for explosive performance. They're complementary, not alternatives.

How long does a 2.5kg bag of Impact Whey Protein last?

At 1 scoop (25g) per day, a 2.5kg bag provides approximately 100 servings — roughly 3 months of daily use. Optimal for regular gym-goers in Singapore.
