Where is psoriatic arthritis hitting you hardest right now?

Painful, swollen, or stiff joints that slow me down

Exercise
Centuries of traditional use across more than one tradition· Limited human trials so far (Evidence grade C · Traditional use classical)Classical use across multiple traditions
Guided movement that eases stiff joints and boosts function
Why this matches
Since painful, stiff joints are your main concern, regular exercise is one of the few self-directed steps studied in psoriatic arthritis itself for improving how your joints move and feel.
Why try it
Strengthening and functional exercise loads joints gently, builds the muscle that supports them, and can lower disease-related stiffness and fatigue. In a psoriatic arthritis trial, both resistance and functional training improved disease-activity and function scores over 12 weeks.
Dose or use
Aim for well-structured strengthening (resistance bands or machines) plus functional movement about twice a week, easing off during acute flares. A physiotherapist can tailor a program to your joints.
Time to results
Strength and stiffness often improve over about 6 to 12 weeks of consistent training.
Key study
Randomized controlled trial (2023, PMID 38093394): Effectiveness of functional training versus resistance exercise in patients with psoriatic arthritis - 41 PsA patients improved in disease activity (DAS-28, BASDAI), function, and quality of life over 12 weeks; both exercise arms improved and there was no non-exercise control group, so the evidence is graded C.
Caution
Start gently and build up gradually; don't push through sharp joint pain, and scale back during an active flare. If a joint becomes hot, very swollen, or suddenly much more painful, check with your doctor before continuing.
Boswellia Serrata
Centuries of traditional use across more than one tradition· Human evidence not yet assessed (Evidence grade not assigned · Traditional use classical)Classical use across multiple traditions

Omega-3 Fatty Acid Deficiency (EPA & DHA)
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Low EPA/DHA can worsen joints and skin
Why this matches
Since inflammation is your focus, a shortfall of omega-3s (EPA and DHA) keeps the body in a more pro-inflammatory state that can aggravate both joints and skin.
Why try it
EPA and DHA help regulate inflammation, and a shortfall is often reflected in joint pain, stiffness, and dry skin - symptoms that echo both the joint and skin sides of psoriatic disease.
Dose or use
Eat oily fish a couple of times a week, or consider a fish-oil supplement to close the gap. Your doctor can advise on amounts.
Time to results
Tissue omega-3 levels rebuild over weeks to a few months of steady intake.

Why this matches
If you're working to calm immune activity, it's worth checking for vitamin D deficiency, which is common in psoriatic disease and linked to more severe symptoms.
Why try it
Vitamin D helps regulate the immune system, so correcting a deficiency removes one factor that can worsen inflammation in psoriatic disease.
Dose or use
Ask your doctor for a simple blood test (25-hydroxyvitamin D). If you're low, they can guide a repletion dose.
Time to results
Levels usually improve over 1-3 months of supplementation.
Key study
Vitamin D deficiency is commonly observed in and associated with severity of psoriatic disease; correcting it as a treatment for psoriatic arthritis has not been confirmed in controlled trials.
Caution
Correct a deficiency under medical guidance; over-supplementing without testing can cause harm.
Vitamin D3
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Immune-regulating vitamin often low in psoriasis
Why this matches
Since you want to calm immune activity, vitamin D3 plays a direct role in regulating the immune system, and low levels are common in psoriatic disease.
Why try it
Vitamin D3 helps regulate immune and inflammatory responses, and it has been studied in autoimmune conditions such as rheumatoid arthritis - though its benefit specifically for psoriatic arthritis has not been confirmed in trials.
Dose or use
Typical maintenance is 1,000-2,000 IU daily, ideally guided by a blood test of your vitamin D level. Take with a fat-containing meal.
Time to results
Blood levels rise over weeks to a few months; ask your doctor to recheck.
Key study
