Based on FDA | Does eating spinach interfere with the effectiveness or absorption of sertraline?

There is no evidence that eating spinach interferes with the absorption or effectiveness of sertraline (an SSRI). Most official guidance states you can continue your normal diet while taking sertraline, and there are no specific warnings about spinach or leafy greens affecting sertraline’s action. ^[1] Sertraline may be taken with or without food, and food does not meaningfully reduce its benefit. ^[1]

What the guidelines say

• Medications information for sertraline advises that, unless your clinician says otherwise, you should continue your normal diet. There is no requirement to avoid vegetables like spinach. ^[1]
• Common cautions with sertraline focus on certain drugs and supplements (for example, St. John’s wort, tryptophan, some migraine medicines), not foods. Dietary restrictions are not generally listed for sertraline. ^[2]

How sertraline is absorbed

• Sertraline is absorbed slowly after you swallow it, with peak blood levels around 6–8 hours, and it is typically taken once daily. This absorption pattern is not known to be negatively affected by routine foods. ^[3]
• In practice, many people take sertraline with food to reduce stomach upset, and this is considered acceptable. Taking sertraline with meals generally does not reduce its clinical effectiveness. ^[1]

Spinach-specific considerations

• Spinach contains vitamin K, oxalate, calcium, iron, and natural nitrates, but these do not have known clinically relevant interactions with sertraline’s metabolism or its transporter pathways at typical dietary amounts. Official sertraline guidance does not list spinach, leafy greens, or dietary nitrates as interactions of concern. ^[1]
• Broader SSRI overviews emphasize interactions with other medicines and some herbal supplements, not vegetables. Food-related advice is usually limited to taking SSRIs with food if you have stomach upset. ^[4]

Common food and drink interactions to actually consider

• Grapefruit juice is a well-known food–drug interaction for some medicines due to effects on intestinal enzymes; however, grapefruit is not routinely listed as a concern for sertraline in standard patient instructions. If you consume large amounts of grapefruit juice and have questions, discussing with a clinician is reasonable, but spinach is not implicated. ^[4]

Bottom line

Based on standard medication guidance and pharmacology, spinach does not interfere with sertraline’s absorption or its effectiveness when eaten in normal amounts. ^[1] If you notice new symptoms after changing your diet or have concerns about specific supplements alongside sertraline, it’s a good idea to review them with your clinician or pharmacist. But you do not need to avoid spinach while taking sertraline. ^[1]
