Wild salmon is a healthier option than farmed salmon, which is often found as it contains a high level of antibiotic, dioxin and PCB levels. Rich in omega-3 fatty acids and astaxanthin, wild salmon oil has a naturally occurring ration of EPA DHA. Wild salmon is a better environmental option than salmon farms that pollute coastal waters. The oil is extracted from the salmon already harvested, using pieces of fish that would be wasted, conserving the existing reserves. Regularly tested for chemical residues and heavy metals to ensure safe fish oil and a pure source.
