1. What is Iso Whey Zero Lactose Free Natural 908g Strawberry and what does it do?
Iso Whey Zero Lactose Free Natural 908g Strawberry is the variant for people with strict lactose intolerance — 100% lactose-free thanks to lactase enzyme added during production.
Per 25 g serving you get 22 g of protein (90% native whey isolate), 4.8 g BCAA and all 9 essential amino acids. The difference from the regular Iso Whey Zero (lactose-reduced 57–68%): here the lactase enzyme completely breaks down the residual lactose into glucose and galactose. Result: <0.1 g lactose per 25 g serving. Natural strawberry flavour — mild and not overly sweet. 36 servings per 908 g tub.
2. Who is Iso Whey Zero Lactose Free Natural 908g Strawberry suitable for?
For adults (18+) with strict lactose intolerance who still want to consume whey protein isolate.
Especially suitable for:
- Strict lactose intolerance (where regular Iso Whey Zero contains too much residual lactose)
- Sensitive digestion that reacts to even small amounts of lactose
- Athletes with IBS-like reactions to dairy
- Families where one person is strictly lactose-free and others are not — can be used by everyone
NOT suitable for: milk allergy (lactose-free is NOT milk-free — it still contains milk protein!), soy allergy (lecithin), strict vegan diet.
3. What does whey isolate do in my diet?
Protein contributes to a growth in muscle mass. Protein contributes to the maintenance of muscle mass. Protein contributes to the maintenance of normal bones
Per 25 g serving, Iso Whey Zero Lactose Free Natural 908g Strawberry provides 22 g of protein at ~88 kcal = 88% of energy from protein.
Combine with regular resistance training.
4. How do I take Iso Whey Zero Lactose Free Natural 908g Strawberry?
1 serving = 25 g powder (~1 scoop) mixed with 200 ml water or a plant-based milk alternative.
- Training days: 1 serving in the morning + 1 serving straight after training
- Rest days: 1 serving in the morning + 1 serving in the afternoon
- Maximum 2–3 servings per day for most users
- For a 'fluffy' texture: use a blender instead of a shaker
- Mixes best with room-temperature water — not above 80°C
5. When is the best time to take Iso Whey Zero Lactose Free Natural 908g Strawberry?
Post-workout within 30–60 minutes + between meals as a quick protein source.
Whey isolate has fast absorption kinetics — amino acids peak in the blood within 60–90 min. On rest days: spread over the day. Being lactose-free also makes it suitable for people who normally avoid post-workout shakes because of stomach complaints.
6. Should I take Iso Whey Zero Lactose Free Natural 908g Strawberry with or without food?
Both work — because it is lactose-free, the usual lactose-related precautions no longer apply.
On an empty stomach for the fastest absorption. There is no longer any difference in lactose tolerance because <0.1 g per serving is below any sensitivity threshold.
7. How long does it take before I notice results?
The main benefit for lactose-intolerant users: no more stomach complaints straight after drinking a shake. For many, that alone is a reason to switch.
8. Which form of whey does suppstore use and why?
Native whey isolate 90% (from Dutch pasture-grazed cows) via CFM (cross-flow microfiltration) + lactase enzyme for lactose breakdown during production.
- Native = extracted directly from fresh milk, not from a cheese-production by-product
- CFM = filtration process without heat or chemical solvents
- Lactase enzyme breaks down residual lactose into glucose + galactose during production
- Retains immunoglobulins and lactoferrin
- 'Natural' line — less sweet than the regular Iso Whey Zero, no artificial colourings
9. What is the difference from the regular Iso Whey Zero?
The key difference is lactose status.
- Regular Iso Whey Zero: lactose-reduced 57–68% (~1 g lactose per serving) — suitable for MILD intolerance
- Lactose Free Natural: 100% lactose-free thanks to lactase enzyme (<0.1 g per serving) — suitable for STRICT intolerance
- The Natural line also has a slightly different flavour profile — less sweet, closer to neutral
If you tolerate the regular Iso Whey Zero well: the price is usually comparable or slightly lower. If even 1 g of lactose gives you stomach complaints: this variant is the right choice.
10. How much protein is in each serving?
22 g of protein per 25 g serving (88% protein purity, ~88 kcal).
- 4.8 g BCAA (leucine + isoleucine + valine)
- 0.6 g added L-glutamine
- All 9 essential amino acids
- <0.1 g lactose
A 908 g tub contains 36 servings — a 36-day supply at 1 serving/day.
11. What does the scientific research say?
Whey isolate is one of the best-researched forms of protein in sports nutrition. Lactase enzyme has been extensively studied and has been used for decades in dairy products for lactose-intolerant consumers.
12. Are there any side effects?
Very well tolerated — specially designed to eliminate typical whey side effects in people sensitive to lactose.
In case of milk protein allergy: not suitable — it still contains traces of casein and β-lactoglobulin. In case of soy lecithin allergy: not suitable. For healthy users: a safety profile comparable to the regular Iso Whey Zero.
13. Who should preferably not use Iso Whey Zero Lactose Free Natural 908g Strawberry?
Do not use in case of:
- Milk protein allergy (casein, β-lactoglobulin) — lactose-free is NOT milk-free!
- Soy allergy (lecithin)
- Strict vegan diet (whey is animal-derived)
- Known kidney disease (consult a doctor first)
14. Is Iso Whey Zero Lactose Free Natural 908g Strawberry safe during pregnancy or breastfeeding?
In moderate doses (max 1 serving per day), whey isolate is generally safe as an additional protein source during pregnancy and breastfeeding.
Whole-food protein sources are preferable. Consult your midwife or GP for individual advice. For pregnant women with lactose sensitivity, lactose-free is a logical choice.
15. From what age can children use Iso Whey Zero Lactose Free Natural 908g Strawberry?
Not specifically formulated for children under 18. For adolescent athletes who need extra protein: use under the guidance of a sports dietitian or GP.
16. Can I combine Iso Whey Zero Lactose Free Natural 908g Strawberry with my medication?
Consult your doctor or pharmacist if you use medication.
- Levodopa — protein intake can affect absorption, take separately
- Tetracycline antibiotics — at least 2 hours apart from milk protein
- Fluoroquinolones — take separately
- Bisphosphonates — on an empty stomach, separate from protein meals
17. Can I combine Iso Whey Zero Lactose Free Natural 908g Strawberry with other supplements?
Combines well with: creatine monohydrate, vitamin D3, magnesium, pre-workout supplements, EAAs for intra-workout.
Avoid combining with other high-protein supplements so that you keep your total protein intake below 2 g per kg of body weight.
18. Which allergens does it contain, and what is it free from?
Contains:
- Milk protein (whey isolate — note: lactose-free is NOT milk-free)
- Soy (lecithin emulsifier)
Free from:
- Lactose (<0.1 g per serving, officially lactose-free)
- Gluten
- Nuts and peanuts
- Eggs
- Fish
- Crustaceans
- Sesame
- Sulphite
- Lupin
- Mustard
- Celery
- Molluscs
Contains natural strawberry flavourings. Important nuance: 100% lactose-free does NOT mean milk-free — it still contains milk protein (whey + traces of casein). In case of cow's milk allergy: this product is NOT suitable.
19. Is Iso Whey Zero Lactose Free Natural 908g Strawberry vegan or vegetarian?
Not vegan (whey comes from cow's milk). Vegetarian, however.
If you are looking for a strictly vegan option: take a look at the plant-based protein alternatives in the suppstore range.
