Red Rex Iso Big: A Whey Isolate for Daily Protein

Red Rex Iso Big is a whey protein isolate with 26g of protein per scoop of about 30g. Isolate is whey that has been filtered further to leave more protein and less lactose, fat and carbohydrate than a standard concentrate, and it is a fast-digesting protein. The 4.63lbs tub gives about 70 servings and is available at Nutritional World. Check the listing for the flavours in stock.

Who It’s For

  • Athletes and gym-goers who want a protein source to support recovery after training

For more detail see the best time to take whey protein and how much whey protein per day.

Who should be cautious: Contains milk. Do not use it if you have a dairy or milk protein allergy. Isolate has much less lactose than concentrate, but it is not lactose-free, so very sensitive people may still react. People with kidney or liver conditions, and anyone on a medically supervised diet, should speak to a doctor before raising protein intake. If you are pregnant or nursing, or have any medical condition or take medication, consult a healthcare professional before use. Not intended for children. Protein powder is a supplement, not a replacement for a varied, balanced diet. Do not exceed the recommended serving. Keep out of reach of children.

Storage

Store in a cool, dry place away from direct sunlight and keep the tub tightly closed after use.

RESEARCH & PUBLICATIONS

Whey Protein and Muscle Recovery

Whey is a complete protein that provides all the essential amino acids, including leucine, and it is digested quickly. Research links adequate protein intake, spread through the day and combined with resistance training, with better muscle recovery and strength gains. Total daily protein and consistent training matter more than any single shake. See how much whey protein per day.

What Isolate Means

Whey isolate is filtered further than concentrate, so it is usually higher in protein per scoop and lower in lactose, fat and carbohydrate. The protein itself is the same type. For many people the main difference is the lower lactose and the price. See whey protein isolate vs concentrate.

This section describes whey protein in general. It is ingredient-level information, not clinical evidence on this finished product, and no study of Red Rex Iso Big itself is cited.
