HelloPharmacist Scorecard of Nutricillin by Ecological Formulas
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Partial disclosure
Nutricillin contains four active ingredients. Olive leaf extract is included for its potential benefit in various conditions, though evidence is limited.
Lactoferrin is a naturally occurring protein believed to play a role in immune and digestive health. Colostrum and lysozyme hydrochloride round out the formula — both are components found in milk and egg white, respectively, and are thought to support immune function.
The product also contains inactive ingredients (gelatin, microcrystalline cellulose, and magnesium stearate) that serve as capsule material and binding agents.
Does it work?
Moderate evidence
The evidence for what this product can actually do is thin. Olive leaf extract has been studied for osteoporosis, upset stomach, exercise-related respiratory infections, shingles, flu, and osteoarthritis, but in each case the evidence is insufficient to rate it.
Lactoferrin shows some promise in sepsis and pregnancy-related iron deficiency (rated possibly effective), but has not proven helpful for reducing fetal or premature infant death or necrotizing enterocolitis (a serious intestinal condition in newborns). For colostrum and lysozyme hydrochloride, the evidence on file does not establish effectiveness.
How safe is it?
Well-documented data
Olive leaf extract and lactoferrin are both generally well tolerated at typical doses. Olive leaf extract most commonly causes headache or stomach discomfort; one person reported acne in a trial.
Lactoferrin at normal doses is well tolerated, though diarrhea and constipation can occur; at very high doses (7.2 grams daily), fatigue, chills, loss of appetite, and constipation become more likely. Olive leaf extract is less studied in concentrated supplement form than as food, so caution is warranted — talk with your doctor before using it if you have concerns.
Long-term safety data for lactoferrin are limited. For pregnancy, lactoferrin appears likely safe based on limited studies, but safety is not fully established — use only under medical supervision.
Lactoferrin is likely safe while breastfeeding, though supplement safety during lactation is not well studied. We hold no safety data on file for colostrum or lysozyme hydrochloride.

The bottom line
Scorecard at a glancePartially disclosed formula with some supporting evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.
This product is a blend of immune-support ingredients with minimal evidence that any of them deliver measurable benefit. Olive leaf extract and lactoferrin are generally well tolerated, but long-term safety data are limited.
