by Klaire Labs
What is this page for?
First and foremost: checking Sibb-Zymes against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
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. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Sibb-Zymes by Klaire Labs
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
Sibb-Zymes contains five active digestive enzymes. Lactase breaks down lactose (milk sugar); glucoamylase and maltase break down starches and their intermediates; sucrase breaks down table sugar; and a protease/peptidase complex breaks down proteins.
The capsule itself is made from hydroxypropyl methylcellulose, with water and microcrystalline cellulose as inactive ingredients.
Does it work?
Strong evidence
Lactase is effective for lactose intolerance — the inability to digest milk sugar. The data we have isn't sufficient to rate lactase for prematurity or colic.
We don't hold effectiveness ratings for the other four enzymes in this product.
How safe is it?
Well-documented data
Lactase is generally well tolerated when used as directed. A rare case of contact dermatitis and allergic rhinoconjunctivitis has been reported in a worker exposed to powdered lactase; if you have a known lactase allergy, this product isn't for you.
For pregnancy, the data suggests lactase is likely safe, but check with your doctor first. We don't have pregnancy or breastfeeding safety data on file for the other enzymes — talk with your doctor or pharmacist before regular use in pregnancy if you're concerned.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. Still, run your medications through the search tool on this page — we don't hold data for several of the enzymes in this blend.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
Sibb-Zymes is a good fit if you have trouble digesting lactose or want broader enzyme support with meals. If you're pregnant or breastfeeding, or if you have a known enzyme allergy, check with your pharmacist first.
No drug interactions are documented for the one ingredient we could fully review.
