Supplement Interaction Audits

No specific zinc-probiotic interaction is established. Check the NIH 40 mg adult zinc UL, strain uncertainty, timing, and when to ask a clinician.

Usually yes — no major ashwagandha-zinc clash is listed. Watch the zinc 40 mg/day UL and review ashwagandha with a clinician if pregnant or…

Ashwagandha and vitamin D3 do not have a major direct interaction in our current rules. The smarter audit is dose size, pregnancy context, and whether…

CoQ10 and magnesium are often used in cardiovascular or energy-support routines. The main audit is medication context, total magnesium load, and whether…

L-arginine and L-citrulline are commonly stacked in circulation or pre-workout routines. Review blood-pressure context, total dose, and stomach tolerance…

Calcium may interfere with iron absorption. Learn why taking them at different times of day may help, and ask a doctor or pharmacist for advice tailored…

Zinc and biotin do not have a major direct interaction in NutriAudit. Review dose, timing, and whether the combo is actually needed before stacking.

Usually fine together. Watch ginkgo with blood thinners (bleeding risk) and vitamin C's 2,000 mg/day NIH UL across powders and multis.

Vitamin D3 and K2 are usually paired for bone support. Check total dose, calcium context, and regional limits before long-term stacking.

Vitamin C can improve iron absorption. The pairing is often helpful, but total iron dose still matters more than the interaction headline.

Iron and zinc can compete when doses are high. If both matter in your plan, spacing them is usually the cleaner strategy.

Calcium and magnesium are often paired, but very unbalanced doses can make the stack harder to tolerate and less efficient.

Usually yes, with timing care — Calcium and Zinc may compete at higher doses. See how to space them and audit your full stack free.

Omega-3 and vitamin E are often paired. The main audit question is whether the total stack pushes bleeding-related caution too far for you.

Usually yes — no major interaction is listed for Magnesium and Melatonin. Check total dose, upper limits, and your full stack free.

Usually yes — no major interaction is listed for Beta Alanine and Creatine. Check total dose, upper limits, and your full stack free.

Usually yes — no major interaction is listed for Magnesium and Ashwagandha. Check total dose, upper limits, and your full stack free.

Yes — Caffeine and L-theanine work well as a pair. See timing, total-dose limits, and a free way to check this combination inside your full stack.

Usually yes — no major interaction is listed for Vitamin D3 and Probiotics. Check total dose, upper limits, and your full stack free.

Usually yes — no major interaction is listed for Collagen and Biotin. Check total dose, upper limits, and your full stack free.

Usually yes — no major interaction is listed for Iron and Magnesium. Check total dose, upper limits, and your full stack free.

Calcium and vitamin D3 are commonly paired, but stacking high doses can still push total calcium exposure too far for some users.

Usually yes — no major interaction is listed for Calcium and Vitamin C. Check total dose, upper limits, and your full stack free.

Usually yes — no major interaction is listed for Iron and Vitamin D3. Check total dose, upper limits, and your full stack free.
