How do I check if two supplements interact?

Add each supplement to the SupStack Interaction Checker. The tool analyzes shared biological pathways, absorption competition, and CYP-enzyme interactions across hundreds of curated supplement pairs, then shows synergies (green), conflicts (red), and neutral pairs (gray) in a matrix view.

What does "synergy" mean for supplements?

A synergy is a pair of supplements whose effects compound when taken together — for example, vitamin D and K2 work together in calcium metabolism. SupStack flags synergies based on shared biological pathways and clinical evidence.

What should I do if I find a conflict?

The "Time them apart" recommendation typically means taking the two supplements at least 2–4 hours apart to avoid absorption competition. For severe conflicts, consider whether both are needed or consult a healthcare provider.

Does SupStack check supplement-drug interactions?

Yes — the Interaction Checker references a curated supplement-drug interaction catalog covering CYP-enzyme effects and common pharmacokinetic conflicts. For a full medication review, the tool surfaces source PMIDs you can take to a pharmacist or physician.
