Find the available answers about tetracycline and supplements. Each guide explains its evidence and the forms it covers.
8 published guides. Coverage is limited to the combinations listed.
Oral tetracycline hydrochloride and oral Angelica sinensis root preparations. Skin contact with a mixed decoction is a separate exposure; other Angelica species are not merged.
Read the interaction guide →Oral tetracycline hydrochloride and oral iron; ferrous sulfate is the directly studied form. Intravenous iron is not assessed by this digestive-tract interaction.
Read the interaction guide →Oral tetracycline hydrochloride and oral Hypericum perforatum extracts. LI 160 studies are ingredient-only evidence, not a direct combination trial; pure hypericin and topical products are distinct.
Read the interaction guide →Oral tetracycline hydrochloride and potassium citrate, including prescription extended-release potassium citrate. Calcium citrate, sodium bicarbonate and other antibiotics remain separate exposures.
Read the interaction guide →Oral calcium citrate and tetracycline hydrochloride capsules. Application of general calcium-supplement guidance to citrate is explicit; no citrate-specific human absorption result is claimed.
Read the interaction guide →Oral tetracycline hydrochloride with magnesium-containing antacids or laxatives. The direct experiment used a combined magnesium/aluminum hydroxide gel; other nutritional salts have limited exact evidence.
Read the interaction guide →Oral tetracycline hydrochloride and zinc products; the direct trial tested zinc sulfate providing 45 mg zinc. Doxycycline is distinct and showed a different result in the same paper.
Read the interaction guide →Oral tetracycline hydrochloride capsules with calcium-containing antacids or supplements. Calcium salt and dose are retained; the effect of every formulation is not quantified.
Read the interaction guide →A supplement missing from this list has not been cleared for use with the medication. These pages do not assess every product, formulation, or combination.
Publication status, clinical review and change history are shown in each interaction guide.
