Essential Amino Acids: A Practical Guide for Adults 45+
An accessible introduction to amino acids, dietary protein and the questions worth asking before considering a supplement.
Amino acids are the building blocks that make up proteins. Some are called essential because the body cannot make enough of them and they need to come from food. This guide introduces the topic without turning it into a sales pitch.
Start with dietary protein
Many foods provide amino acids, and a varied diet can include a mix of plant and animal sources. A supplement is not automatically better than food, and more is not always more useful.
Questions to ask about a product
Consider the ingredient list, serving size, independent quality information, cost and whether the product fits your existing diet. Be cautious with broad promises that are not supported by clear evidence.
Who should ask for advice first?
Anyone managing a health condition, taking medication, pregnant or nursing, or preparing for surgery should discuss supplements with an appropriate healthcare professional.
