Why Isagenix makes this one
What it was built to do
A single foundational system replacing the practice of stacking separate gut products.
What actually makes it different
The only Isagenix lactoferrin or colostrum product: 200mg effera lactoferrin, 1g colostrum, 3g fibre, 8B CFU.
Who it suits
Ages 4+, one scoop daily, wanting gut barrier, immune and recovery support from one product.
The dividing line
FiberPro: less fibre, but adds postbiotics, colostrum and lactoferrin. Isagenix publishes no guidance on choosing.
Where the lactoferrin claim comes from
The 25-times-more-lactoferrin comparison is against standard bovine colostrum products, and the doubling figure comes from human immune-cell studies rather than from people taking the finished product. Both are specific, defined company comparisons. Neither is a clinical outcome in someone drinking it.
Where the brand does not explain itself
This product and FiberPro overlap enough that most buyers ask which one they need. Isagenix publishes no rationale for both existing and no guidance on choosing between them. We are not going to invent one. What we can tell you is what actually differs, which is the dividing line above — and that if the brand had a cleaner answer, it would be on their page and not only on ours.
Details the shop page leaves out
- Per scoop: 3g prebiotic fibre, 8 billion CFU at manufacture, 1g cold-processed grass-fed colostrum and 200mg effera lactoferrin. It contains dairy, because of the colostrum.
- Suitable from age 4, any time of day, with or without food, up to two servings daily.

What the label says
Mix one scoop with 8 fl oz of water once daily; up to two servings a day. The formula is built around effera lactoferrin, grass-fed bovine colostrum, prebiotics, probiotics and postbiotics.
How to read that
The product sheet makes specific comparison claims — 25 times more lactoferrin than standard bovine colostrum products, and up to double the effect in human immune-cell studies. Those are narrowly defined company comparison claims measured in cells, not evidence of a broad clinical outcome in people taking it.
