rheumatoid-arthritis. Multiple studies demonstrate significant improvements in morning stiffness, joint pain and overall disease activity with GLA supplementation (1.4-2.8 g daily), with combination of GLA and omega-3 fatty acids showing enhanced efficacy compared to either alone.
atopic-dermatitis. Clinical trials of GLA in atopic dermatitis show mixed but promising results with some reporting reduced symptom severity, and efficacy appears to correlate with the plasma GLA levels achieved during treatment.
asthma. Combined GLA/omega-3 supplementation reduces leukotriene generation and improves quality of life in mild asthmatics, with a 50% reduction in basophil and 35% reduction in neutrophil leukotriene production.
