Choosing Between Them
Choosing Dr. Berg Omega-3 gives you the best balance of strict four-stage purity testing and palatability, making it my top recommendation for Dr. Berg fans. If you have different priorities, the pure Icelandic option suits origin purists, while the NOW supplement serves budget-conscious daily users well.
You should always verify third-party heavy metal certificates before adding any marine oil to your daily routine. Market standards shift frequently, and independent verification remains your best safety net.
