Why undenatured whey protein?

Undenatured whey protein is less processed than standard whey protein, which means it retains more of the essential vitamins and minerals your body needs, as well as more amino acids, the building blocks of protein and muscle.

Isagenix pride themselves on providing only the best-quality products, free from chemicals and anything artificial. That’s why the protein in IsaLean Pro comes from dairy cows that are not injected with hormones, so you know exactly what you’re putting into your body.

protein building blocksHow does protein work?

Proteins are the building blocks of life, and essential to building and maintaining lean muscle, and. everyone needs protein, not just professional athletes. Whether you’re trying to lose weight, or pack on additional lean muscle, protein should be a staple part of your diet.

You’ll find protein in foods like meat and fish, as well as dairy and beans, but often, they come attached to lots of unwanted calories. That’s where IsaLean Pro comes in.

IsaLean Pro is protein, carbohydrates, good fats, fiber, vitamins and minerals, without the excess calories. In fact, each meal replacement shake contains 280 calories – the ideal amount to deliver the nutrition you need, without the weight gain.

Kind to allergy sufferers

IsaLean Pro is gluten and soy-free, meaning you can get plenty of daily nutrition, without having to worry about unwanted side-effects.

  • Gluten-free
  • Soy-free

Isagenix shakes also have a low glycemic index rating, which means they won’t play havoc with your blood sugar levels. If you’re diabetic, it’s still always best to check with your doctor before trying anything new like this.

Break through weight loss plateaus

Stumbling blocks in your weight loss journey can pop up for a variety of reasons, including cravings and boredom with the current selection of foods on offer. If you’re following a weight loss plan, but still finding that you’re hungry, it could be that you’re not getting enough protein.

Protein, unlike the refined carbohydrates which are often to blame for weight gain, is very filling. It’s harder to overeat protein, and even a small amount keeps you feeling satisfied for longer.

Break through weight loss plateaus by keeping your protein intake high, and reducing the likelihood of overeating.

Protect against age-related muscle loss

Getting older can mean that muscles don’t repair or build as easily as they used to on their own. With IsaLean Pro, muscles get a powerful protein and nutrient boost, to help them stay in tip top condition.

Protein isn’t just the savior of bodybuilders and gym rats, it’s for everyone. Take back control of your health and help yourself to feel better than ever.
