Keep Moving
Choose activities that suit your abilities, such as walking, swimming, cycling or appropriate strength exercises. Regular movement can help maintain muscle strength and joint function.
Understanding Your Body
Hyaluronan & the science of joint health.
Healthy joints help us move through everyday life. Learn how hyaluronan contributes to joint lubrication, why synovial fluid matters, and which everyday habits can help support mobility and overall joint health.
Movement matters
Everyday activity can help maintain strength, mobility and function.
01 / The Basics
What helps joints move smoothly?
Many freely movable joints contain a small amount of synovial fluid. This fluid helps lubricate joint surfaces and supports the environment in which articular cartilage functions.
One of its important components is hyaluronan, also called hyaluronic acid. This naturally occurring molecule binds water and contributes to the thickness and elastic properties of synovial fluid.
These properties help joints cope with movement and loading. Healthy joint function, however, depends on several structures, including cartilage, bone, muscles, tendons and ligaments.
Did you know?
Hyaluronan occurs naturally in several tissues throughout the body, including the skin, eyes and joints.
02 / Why It Matters
One molecule, part of a larger system.
Hyaluronan contributes to the viscosity and lubrication properties of synovial fluid. The fluid's composition and performance can change with age and certain joint conditions.
These changes are only one part of joint health. Cartilage, surrounding muscles, connective tissues and the joint lining all play important roles in movement and function.
No single molecule determines whether a joint will remain comfortable or develop a condition such as osteoarthritis. Joint symptoms and treatment options vary from person to person.
Understand the whole joint
Cartilage: Covers the ends of bones and provides a smooth surface for movement.
Synovial fluid: Helps lubricate movable joints and supports the cartilage environment.
Muscles and connective tissues: Help support joints and contribute to stability and movement.
03 / Everyday Movement
Habits that help support joint health.
There is no single food or routine that guarantees healthy joints. Regular activity, balanced nutrition and appropriate recovery can all contribute to overall well-being.
Eat a Balanced Diet
Include a variety of vegetables, fruits, whole grains, protein sources and unsaturated fats. A balanced eating pattern helps supply nutrients needed for general health and normal body functions.
Allow Time to Recover
Increase exercise gradually, adapt activities when needed and allow time for recovery. Persistent or worsening pain deserves attention rather than being ignored.
04 / Nutrition & Evidence
Sweet potatoes and other plant foods.
Satsumaimo is a Japanese name for sweet potato. Depending on the variety and preparation, sweet potatoes provide carbohydrates, dietary fiber and nutrients such as beta-carotene.
They can be part of a varied, balanced diet, alongside other vegetables, fruits, whole grains and suitable protein sources. No individual food needs to carry the responsibility for maintaining joint health.
Researchers continue to investigate relationships between dietary patterns, inflammation and joint conditions. However, eating sweet potatoes has not been established as a way to replenish hyaluronan in synovial fluid or reverse joint damage.
Keep the evidence in perspective
A nutritious eating pattern supports general health, but no single food has been proven to restore joint hyaluronan or guarantee prevention of osteoarthritis.
05 / Listen to Your Body
When should you seek professional advice?
Joint discomfort and stiffness can have many causes. If pain, swelling, stiffness or reduced movement persists, keeps returning or interferes with daily activities, a qualified healthcare professional can help assess the cause.
A joint that becomes suddenly very painful, hot or swollen needs urgent medical assessment, especially if you also have a fever or feel generally unwell.
Learning how joints work can help you ask informed questions and make thoughtful decisions about movement, nutrition and appropriate care.
Understand before choosing
Be cautious of claims that a particular food, supplement or routine can rebuild cartilage, replace joint fluid or guarantee relief. Products and treatments can differ in their evidence, risks and suitability.
