Check interactions
Add your supplements, foods, meals — and any medications you take — to see how they interact. Findings are grouped by severity: what to avoid, what needs care or timing, and what actually works better together.

Avoid
1 · Don't combine without medical guidanceVitamin K2 counteracts warfarin and can reduce its anticoagulant effect.
Why: Vitamin K regenerates clotting factors warfarin suppresses.
→ Only under prescriber guidance with INR monitoring.
Caution
16 · Combine carefully — read the noteAlgal Oil (Vegan DHA): Same as fish oil
DHA (Docosahexaenoic Acid): Blood thinners - additive effect
EPA (Eicosapentaenoic Acid): anticoagulants (warfarin, dabigatran) — increased bleeding risk at high doses; monitor INR
EPA (Eicosapentaenoic Acid): antiplatelet agents (aspirin, clopidogrel) — additive antiplatelet effect at high doses
EPA (Eicosapentaenoic Acid): NSAIDs — may increase GI upset risk
Olive: Diabetes meds (additive blood sugar)
Selenium: May affect thyroid medication needs
Vitamin D: Glucocorticoids (reduced vitamin D effectiveness)
Vitamin D: Anticonvulsants like phenytoin (increased vitamin D metabolism)
Vitamin D: Orlistat (reduced fat-soluble vitamin absorption)
Vitamin K2: Warfarin and other coumarin anticoagulants—may reduce anticoagulant effect; consistency is key
Vitamin K2: Some antibiotics (broad-spectrum) may reduce K2 production by gut bacteria
Monitor / Timing
3 · Usually fine — mind timing or watch for effectsMagnesium can bind these drugs and reduce their absorption.
Why: Cation chelation in the gut.
→ Separate magnesium from these medications by 2–4 hours.
Vitamin D: Magnesium (needed for vitamin D metabolism)
Vitamin D: K2 (complementary for bone and cardiovascular health)
