As we discussed in an earlier blog post, chronic inflammation can play an important role in many health conditions associated with aging. One common group of conditions influenced by inflammation, metabolic health, body weight, immune function, genetics, and lifestyle is arthritis.
Arthritis can significantly affect mobility, sleep, independence, and overall quality of life. But arthritis is not one single disease—it is a broad term that includes many different joint conditions.
From an integrative perspective, it is important not only to identify the type of arthritis, but also to look at the whole person—including nutrition, metabolic health, body composition, movement, sleep, stress, and other factors that may influence inflammation and healing.
What Is Arthritis?
Arthritis literally means joint inflammation. It can affect the knees, hips, shoulders, elbows, hands, feet, spine, and other joints.
Three common forms are osteoarthritis, rheumatoid arthritis, and gout.
Osteoarthritis
Osteoarthritis (OA) is the most common form of arthritis. It involves gradual changes in the cartilage, bone, and surrounding tissues of a joint.
Symptoms may include pain with movement, stiffness after resting, swelling, and decreased range of motion. Aging increases risk, but previous injuries, excess body weight, repetitive stress, muscle weakness, genetics, and joint structure may also contribute.
Osteoarthritis should not be confused with osteoporosis. Osteoarthritis affects joints, while osteoporosis involves loss of bone density and increased fracture risk.
Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory condition in which the immune system attacks tissues within the joints.
It can cause pain, swelling, warmth, stiffness, fatigue, and loss of joint function. Because rheumatoid arthritis is systemic, it may also affect other parts of the body.
Early diagnosis is important because uncontrolled RA can lead to permanent joint damage. Nutrition, exercise, sleep, stress management, healthy body composition, and other lifestyle strategies can be valuable parts of a comprehensive plan along with appropriate medical care.
Gout
Gout is an inflammatory form of arthritis caused by the buildup of uric acid and the formation of urate crystals around a joint.
It may cause sudden, intense pain, redness, warmth, and swelling—often beginning in the big toe.
Genetics and kidney function are important, but gout is also strongly connected with metabolic health. Obesity, insulin resistance, alcohol, sugar-sweetened beverages, certain foods, medications, and other factors may influence risk.
What About Lupus?
Lupus is not a form of arthritis, although arthritis and joint pain are common symptoms.
Lupus is an autoimmune condition that may affect the joints as well as the skin, kidneys, lungs, heart, nervous system, and other tissues.
Looking Beyond the Joint
A painful joint does not exist separately from the rest of the body.
Joint health can be influenced by muscle strength, body composition, circulation, nutrient status, glucose and insulin regulation, sleep, oxidative stress, immune function, previous injuries, and overall inflammatory burden.
This does not mean every case of arthritis has one hidden “root cause.” Rather, there may be modifiable contributors that can be addressed to help create a healthier internal environment.
Metabolic Fitness and Inflammation
We frequently use the term metabolic fitness to describe how effectively the body manages energy, blood glucose, insulin, lipids, and other aspects of metabolism.
Poor glucose regulation, excess visceral fat, lack of activity, insufficient sleep, and highly processed diets can all contribute to an unfavorable metabolic environment.
This is particularly relevant for osteoarthritis. Excess weight increases mechanical stress on weight-bearing joints, but fat tissue is also metabolically active and can influence inflammatory signaling throughout the body.
Improving metabolic health can therefore benefit much more than the number on the scale.
Nutrition and Joint Health
Nutrition is one of the most powerful lifestyle tools available to us.
A good starting point is a diet centered around whole or minimally processed foods, including vegetables, quality proteins, healthy fats, nuts, seeds, legumes, fish, herbs, spices, and other nutrient-dense foods.
For many people, reducing added sugar, refined carbohydrates, sugar-sweetened beverages, and heavily processed foods is an important first step toward improving metabolic health.
Mediterranean-style eating patterns are also well studied and emphasize vegetables, fruits, olive oil, fish, nuts, seeds, legumes, and minimally processed foods.
For gout, nutrition becomes more specific. Reducing excessive alcohol and sugar-sweetened beverages and moderating certain high-purine foods may help.
There is no perfect “arthritis diet” for everyone. Nutrition should be individualized based on metabolic health, food tolerance, medical conditions, medications, and how the individual responds.
Movement Is Medicine
Movement is one of the most important tools we have for supporting joint health.
Exercise strengthens the muscles surrounding joints, supports bone health, improves balance and mobility, and benefits metabolic and cardiovascular health.
A combination of aerobic exercise, resistance training, mobility work, and balance training can be especially valuable when adapted to the individual.
Yoga, Tai Chi, aquatic exercise, and physical therapy may also be useful.
The goal is not to push through significant pain, but rather to find the right type and amount of movement and gradually build strength and capacity.
Weight, Body Composition, and Metabolic Health
When excess weight is present, improving body composition can reduce stress on weight-bearing joints such as the knees and hips.
Preserving and building muscle mass while improving insulin sensitivity and reducing excess visceral fat is an important part of healthy aging.
Semaglutide and Tirzepatide
Semaglutide and tirzepatide have changed the approach to medical weight management.
These medications influence appetite, satiety, glucose regulation, and metabolism and can produce significant weight loss in appropriately selected individuals.
This may be particularly important for people with osteoarthritis because reducing excess weight decreases stress on weight-bearing joints.
Emerging research is also interesting. A 2024 clinical trial involving people with obesity and moderate-to-severe knee osteoarthritis found that participants receiving semaglutide experienced greater weight loss and greater improvement in knee pain than those receiving placebo.
These medications are not arthritis treatments themselves, but the findings highlight the important relationship between metabolic health, body composition, inflammation, and joint health.
NAD+, Mitochondrial Health, and Inflammation
One of the rapidly developing areas of healthy-aging research involves NAD+, or nicotinamide adenine dinucleotide.
NAD+ is naturally present in our cells and plays important roles in:
- Cellular energy production
- Mitochondrial function
- DNA repair
- Redox balance
- Cellular stress responses
- Immune regulation
Research increasingly suggests a connection between NAD+ metabolism and immune cells involved in inflammatory signaling.
Most human research has focused on NAD+-supporting compounds such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). These compounds can increase NAD-related metabolites, although their effects on inflammation, metabolism, and physical performance have varied between studies.
Injectable NAD+ is also used in some integrative and healthy-aging practices with the goal of supporting cellular metabolism and recovery.
Glutathione and Oxidative Stress
Glutathione (GSH) is one of the body’s most important natural antioxidant and redox-regulating compounds.
It helps protect cells from oxidative stress, supports immune function, recycles other antioxidants, and participates in the body’s normal detoxification pathways.
Oxidative stress and inflammation are closely connected. When the production of reactive oxygen species exceeds the body’s ability to regulate them, cellular damage and inflammatory signaling may increase.
Injectable glutathione is used in integrative medicine as a supportive therapy aimed at antioxidant and cellular support.
Sleep, Stress, and Recovery
Sleep and recovery are often overlooked.
Poor sleep can affect glucose regulation, pain perception, appetite hormones, immune function, and inflammatory signaling.
Chronic stress can also affect sleep, food choices, muscle tension, pain perception, and immune function.
Meditation, breathing exercises, yoga, Tai Chi, time outdoors, and other stress-management practices may all be useful parts of a broader wellness plan.
Heat, Cold, and Supportive Therapies
Heat can help relax muscles, reduce stiffness, and improve comfort, while cold therapy may temporarily reduce pain and swelling.
Some individuals also incorporate sauna, cold exposure, massage, acupuncture, and other recovery strategies into their wellness programs.
Nutrients and Emerging Therapies
Nutrition should remain the foundation, but targeted supplementation may also be useful.
Depending on the individual, vitamin D, magnesium, calcium, omega-3 fatty acids, antioxidants, and other nutrients may be appropriate based on diet, laboratory findings, medications, bone health, and overall health goals.
Peptide-based and other emerging therapies are also becoming increasingly interesting areas of integrative and healthy-aging medicine. The research is developing quickly, and there is still much to learn about which therapies may be useful, for whom, and under what circumstances.
When Should You Seek an Evaluation?
Occasional aches and stiffness can occur for many reasons, but persistent or recurring joint pain, swelling, stiffness, or loss of mobility deserves attention.
A joint that suddenly becomes extremely painful, red, hot, or swollen—especially when accompanied by fever or feeling ill—should be evaluated promptly.
A comprehensive assessment may include your health history, physical examination, blood work, imaging, and other testing depending on your symptoms.
Identifying what type of arthritis is present is important because the best approach can differ significantly from one person to another.
The Bottom Line
Arthritis becomes more common as we age, but joint pain should not simply be dismissed as “getting older.”
Understanding which type of arthritis is present is the first step. From there, it is important to look at the whole person.
Nutrition, movement, muscle mass, body composition, metabolic fitness, sleep, stress management, and antioxidant support can all play important roles in supporting healthier joints and overall health.
Emerging approaches involving NAD+, glutathione, metabolic therapies, peptides, and other integrative strategies are also expanding our understanding of the relationship between cellular health, metabolism, inflammation, and aging.
The goal is not to rely on one medication, supplement, injection, or diet as the answer. It is to identify modifiable contributors and develop an individualized strategy that supports better movement, healthier aging, and improved quality of life.
If you are experiencing persistent joint pain, swelling, stiffness, or loss of mobility, speak with your healthcare practitioner about a comprehensive evaluation and individualized plan.
