After extensive search for the best / cheapest omega-3 product I came across the Tetesept capsules. They are characterized on the one hand by the high dosage of 180mg EPA and 120 DHA from (which are not found in all the products, as some manufacturers trick when specifying for example by the consumption amount is not one but several capsules corresponds and the titling of the product then refers mostly to the consumption amount, but not to the fatty portion of a capsule). In addition, the price is unbeatable, especially as it may be by the test of Stiftung Warentest quite safe here, that it is high-quality, pollution-free fatty acids.
Conclusion: In my opinion, probably the best Omega-3 products on the market
