Proper citation is one of the most important parts of academic and scientific writing. Whether you’re writing a research paper, journal article, medical report, thesis, or assignment, citing sources correctly helps maintain credibility and prevents plagiarism.
One citation style that is widely used in medicine, healthcare, nursing, biology, and scientific research is the American Medical Association (AMA) citation style. Among its key features is the use of numbered references within the text, known as AMA in text citations.
If you’re new to AMA formatting or need a refresher, this guide will explain everything you need to know about AMA in text citation, including formatting rules, examples, common mistakes, and best practices.
What Is AMA In Text Citation?
An AMA in text citation is a numbered reference that appears within the body of a paper and directs readers to a corresponding source in the reference list.
Unlike citation styles such as APA or MLA that use author names and publication years within the text, AMA uses numbers to identify sources.
Example
Recent studies show that regular exercise improves cardiovascular health.¹
In this example, the number “1” refers to the first source listed in the reference section.
What Does AMA Stand For?
AMA stands for the American Medical Association.
The organization developed a citation style primarily used in:
- Medicine
- Healthcare
- Nursing
- Public Health
- Biology
- Pharmacology
- Scientific Research
- Medical Journals
- Clinical Studies
- Health Sciences
Today, AMA style is widely accepted across medical and scientific disciplines.
Why Is AMA In Text Citation Important?

Using AMA citations correctly offers several benefits.
Gives Credit To Original Authors
Citations acknowledge the work of researchers whose ideas and findings you use.
Prevents Plagiarism
Proper citations help avoid academic misconduct by showing where information originated.
Improves Credibility
Well-cited papers appear more trustworthy and professional.
Helps Readers Verify Sources
Readers can easily locate the original materials referenced in your work.
Meets Academic Requirements
Many universities, journals, and research institutions require AMA formatting.
How AMA In Text Citations Work
AMA style assigns a number to each source when it first appears in the text.
The same number is used every time that source is cited again.
Example
Researchers found that sleep quality affects cognitive performance.¹
Later in the paper:
Poor sleep habits may also increase health risks.¹
Notice that the same source continues to use the same citation number.
AMA In Text Citation Format
AMA citations generally appear as superscript numbers.
Standard Format
Research suggests that hydration improves physical performance.¹
Alternative Format
Some instructors or publications allow numbers in parentheses.
Research suggests that hydration improves physical performance.(1)
However, superscript formatting remains the most common AMA standard.
How To Cite A Single Source In AMA Style
When citing a source for the first time, assign the next available number.
Example
Exercise has been linked to lower blood pressure.²
The source corresponding to number 2 will appear in the reference list.
How To Cite Multiple Sources
When several sources support the same statement, include multiple citation numbers.
Example
Several studies support this conclusion.¹,³,⁵
This tells readers that multiple references support the information.
How To Cite Consecutive Sources
When citing a sequence of references, use a hyphen to indicate a range.
Example
Numerous studies have investigated this topic.²-⁶
This citation includes references 2 through 6.
How To Reuse A Citation Number
One of the most important AMA rules is that citation numbers never change.
Example
First citation:
The study showed significant improvement in outcomes.⁴
Later citation:
Similar findings were reported in follow-up research.⁴
The original number remains the same throughout the document.
Where To Place AMA In Text Citations
AMA citations are typically placed immediately after the information being referenced.
Citation After A Sentence
Physical activity reduces the risk of heart disease.⁵
Citation After A Quote
The researchers described the results as “highly significant.”⁶
Citation With Multiple Statements
Several factors contribute to chronic disease development.⁷
Proper placement helps readers identify the exact source of information.
AMA Citation Examples
Journal Article Example
Recent research has demonstrated improved patient outcomes following treatment.¹
Book Example
Nutritional factors play a significant role in disease prevention.²
Website Example
Health guidelines continue to evolve as new evidence emerges.³
Each source receives a unique citation number.
AMA Meaning In Text — Quick Reference Table

AMA In Text Citation For Multiple Authors
AMA in-text citations do not change based on the number of authors.
Whether a source has one author or ten authors, the citation format remains the same.
Example

The author information appears only in the reference list.
