Fish oil and omega-3 capsules are among the most researched nutritional supplements available, primarily valued for their contribution to normal heart function and healthy triglyceride levels. The active fatty acids, EPA and DHA, are derived from cold-water oily fish such as salmon, mackerel, sardines, and anchovies, and are difficult to obtain in adequate amounts from diet alone. That gap is where supplementation becomes practical. The range at Ronaghan's Pharmacy spans standard fish oil softgels, high-strength concentrated EPA/DHA formulas, and enteric-coated capsules designed to reduce the aftertaste some people notice with lower-grade products. Dosing varies considerably between products: a standard softgel typically provides 300 mg of combined EPA and DHA, while pharmaceutical-grade concentrates can deliver 1,000 mg or more per capsule. Choosing the right strength depends on your dietary intake of oily fish and your specific reason for supplementing. All products are sourced from carefully selected, trusted brands and are available in a range suited to everyday maintenance as well as targeted cardiovascular or joint support.
