MegaOmega contains highly concentrated fish oil, EPA (eicosapentanoic acid) and DHA (docosahexanoic acid). The 300mg EPA and 200mg DHA per capsule is significantly higher than traditional 180/120 concentrations, while maintaining the proven 60/40 ratio. MegaOmega fish oil concentrate is derived from deap sea, cold water fish and is independently tested for PCBs, heavy metals and other contaminants. This ultra-refined, molecularly distilled fish oil concentrate also contains natural lemon oil that helps ensure good taste and prevent repeating.
