AMA Citation Format: The Student’s Guide to American Medical Association Style

If you’re writing a paper in the medical or health sciences field, chances are you’ve been told to use AMA style—but no one really told you how. Sound familiar?

Whether you’re working on a nursing paper, public health assignment, or biology research project, this guide will help you understand the AMA citation format in plain language—without the confusion.

📘 What Is AMA Style?

AMA stands for the American Medical Association, which developed this citation style to standardize medical and scientific writing. It’s widely used in:

• Medicine

• Nursing

• Pharmacy

• Public health

• Biomedical sciences

• Life sciences

The AMA Manual of Style is currently in its 11th edition, and while it can seem technical at first, once you get the hang of it, it’s very practical.

🧠 AMA Style Basics at a Glance

Here’s what sets AMA apart:

✅ Numbers in superscript for in-text citations
✅ References listed in the order they appear (not alphabetical)
✅ No author-date format like APA or MLA
✅ Abbreviated journal names
✅ Consistent punctuation and format rules

🔹 AMA In-Text Citation Format

Instead of putting the author’s name or date in parentheses, AMA uses superscript numbers that refer to the full reference at the end of the paper.

✅ In-Text Example:

The study shows a strong correlation between diet and cholesterol.¹

If you cite the same source again, just use the same superscript number. No need to repeat it in the reference list.

✅ Multiple Sources:

Recent studies have examined these effects.²⁻⁴

Use hyphens for ranges and commas for separate citations.

📋 AMA Reference List Format

At the end of your paper, create a References page. Number your sources in the order you used them, and match them to the in-text citation numbers.
