ON Whey Protein Isolate Chocolate Powder 907g is a fast-absorbing whey protein supplement crafted to support lean muscle growth, recovery, and daily protein intake. Made exclusively with 100% whey protein isolate, each serving delivers 25g of high-quality protein along with naturally occurring BCAAs and EAAs to help fuel muscle repair after workouts. Its advanced filtration process helps reduce fat, sugars, and lactose while maintaining a clean nutritional profile. The rich chocolate flavour offers a smooth and satisfying taste, and the instantized formula mixes effortlessly in water or milk without clumps. With Informed-Choice certification and a gluten-free formulation, this protein powder is ideal for athletes, gym-goers, and fitness-conscious individuals seeking a premium-quality protein supplement.
Follow these step-by-step instructions to maximise protein absorption and muscle recovery:
Optimal Timing: For best results, consume within 30 to 45 minutes post-workout (the "anabolic window"). It can also be consumed first thing in the morning or between meals to meet daily protein targets.
Pro Tip: For a slower-digesting nighttime shake, mix this whey isolate with a casein-rich base like milk or Greek yoghurt to provide a sustained amino acid release while sleeping.
While generally recognised as safe for healthy adults, please observe the following clinical and safety precautions:

ON Whey Protein Isolate Chocolate 907g undergoes advanced cross-flow microfiltration. This process removes almost all the fat, carbohydrates, and lactose found in standard whey concentrate, resulting in a product that is over 80% pure protein by weight, faster digesting, and much easier on the stomach.
Yes, largely. Because it is a highly purified isolate, the lactose content is significantly reduced to trace amounts. Most individuals with mild to moderate lactose intolerance can consume this without gastrointestinal discomfort, though severely sensitive users should consult a physician.
No. Optimum Nutrition products are strictly manufactured in GMP-compliant facilities and are Informed-Choice certified. This means the product is regularly tested by independent laboratories to guarantee it is entirely free from steroids and athletic banned substances.
The 907g tub provides approximately 29 standard servings, assuming you strictly use the provided 31g measuring scoop.
Absolutely. Whey protein is a macro-nutrient, not a hormone. It safely supports lean muscle maintenance, recovery, and overall dietary protein requirements for both men and women.
From a clinical and athletic standpoint, the optimal time is within 30 to 45 minutes immediately following resistance or endurance training. Its rapid absorption profile quickly supplies muscles with necessary amino acids to halt breakdown and begin repair.
Whey protein can aid in weight management by increasing satiety (feeling full) and supporting lean muscle mass. More muscle mass increases your resting metabolic rate. However, it must be paired with a caloric deficit and regular exercise for weight loss.
Soy lecithin is used in minute quantities (less than 1%) as an emulsifier. It is an "instantizing" agent that allows the whey powder to mix smoothly and quickly in water without clumping.
It is not recommended to mix whey isolate directly into boiling liquids, as high heat can denature the protein structures and cause the powder to clump aggressively. If you wish to make a hot chocolate protein drink, mix the powder with a little cold water first to form a paste, then slowly stir in warm (not boiling) liquid.
All authentic Optimum Nutrition products sold through authorised platforms like Apollo come with a unique verification scratch code on the tub. You can enter this code on the official TrueON website to confirm your product's authenticity.
