Shakes
Six proteins sit here and they are not interchangeable. One replaces a meal, one is a booster you add to a shake, one is built around training, one is a clear juice-style drink. Start with the job you need done.
How these differ from each other
This is the question the category actually raises, and the one the official shop does not answer on a listing page. One line each:
- IsaLean Protein Shake — Plant-Based IsaLean differs by protein source only; Performance Protein by dose only, 24g vs 36g.
- IsaLean Protein Shake, Plant-Based — Plant-Based IsaLean differs by protein source only; Performance Protein by dose only, 24g vs 36g.
- IsaLean Performance Protein — Tri-Release: the brand calls this a full meal replacement and Tri-Release a multistage protein supplement.
- Tri-Release Protein — 1ct — IsaPro: release profile and Velositol. Performance Protein: supplement versus complete meal.
- Tri-Release Protein — 2ct — IsaPro: release profile and Velositol. Performance Protein: supplement versus complete meal.
- IsaPro Whey Protein — Performance Protein: one IsaPro scoop plus 1.5 IsaLean scoops approximates it with fewer carbs.
- Clear Protein — IsaPro: Isagenix publishes no rationale for both. The real difference is clear versus creamy, isolate, and electrolytes.
The numbers behind a Shake Day
A typical Shake Day of two shakes and two snacks contributes under 1,000mg of sodium from Isagenix products, against a general adult guideline of under 2,300mg a day.
A 20-40g protein meal raises muscle protein synthesis roughly two to three fold, and protein feeding can inhibit muscle protein breakdown by about half in young healthy muscle. Roughly 20-30% of protein calories are spent on digestion — the highest thermic effect of the three macronutrients.
The stated target is a 500-1,000 calorie daily deficit for about one to two pounds a week, paired with at least 0.75g of high-quality protein per pound of ideal body weight.
