Potent-Sea is totally different from hemp seed oil and fish oil. Hemp Seed Oil doesn’t contain EPA & DHA - but it is a good source of ALA. Potent-Sea is similar to fish oil based on its amounts of EPA & DHA and health benefits, but it is much healthier because it doesn’t contain heavy metals like mercury. Potent-Sea is also 100% ocean and environmentally friendly, whereas fish oil is not. Compared to Potent-Sea, Phytoplankton has much lower levels of omega-3s, but it is a whole food source and is incredibly beneficial for its minerals, amino acids, and superoxide dismutase (the king of antioxidants).
