Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place.

HelloPharmacist Scorecard of Natural Immune Support Concentrate by Oxygen Nutrition TriGuard Plus
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
Low disclosure
This liquid concentrate has 3 active ingredients. Olive leaf extract is the one ingredient we hold complete data on — it's a concentrated form of compounds from the olive plant.
The product also contains an OLE-100 Complex (a proprietary blend), plus silver water and European black elderberry fruit extract; we don't have monograph data for the last two, so we can't say what they do or what's in them. The inactive ingredients are glycerin and purified water.
Does it work?
Not established
For olive leaf extract, the evidence we hold shows insufficient reliable evidence to rate its use for osteoporosis, indigestion (dyspepsia), exercise-induced respiratory infections, shingles, flu, or osteoarthritis. We have no effectiveness data on file for the OLE-100 Complex, silver water, or European black elderberry fruit extract.
How safe is it?
Well-documented data
Olive leaf extract appears well tolerated when used orally. In trials, a small number of people reported headache or stomach discomfort, and one person reported skin problems and acne.
That said, while olives and olive oil as foods are very safe, concentrated supplements like the one in this product are less well studied — the safety data is incomplete. Olive tree pollen can trigger seasonal respiratory allergy in some people.
We don't have safety data on file for silver water or European black elderberry fruit extract.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That doesn't mean none exist — we simply have no monograph data for silver water or European black elderberry fruit extract, so we can't comment on them.
Before you start, run your exact medications through the interaction checker on this page, and let your doctor or pharmacist know you're thinking about adding this.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.
If you're looking to explore immune support, this product has olive leaf extract and elderberry fruit, both familiar to many people, though the evidence for their use here isn't well established. The biggest question is the concentrated olive leaf extract — it's not like eating olives at dinner, and the safety picture isn't clear.
Talk with your doctor or pharmacist before starting, especially if you have allergies or take other supplements.
