Everybody knows that omega 3 is on the good supplements list. Study after study shows that bodies respond favourably to the omega-3 fatty acid called DHA, or docosahexaenoic acid, which is found in red meat, egg yolks, and in oily fish such as sardines and tuna. Low levels of DHA are linked to depression, memory loss, visual disorders, and other neurological problems. 

For this reason, many of us take fish oil capsules. However, not all omega 3 supplements are created equal. Clinical studies use daily doses of at least 3,000mg of DHA and EPA but if you go shopping at your local pharmacy or supermarket, you'll often find capsules offering 10 times less that strength. Hardly worth taking at all really. 

Brighton-based startup Bare Biology has sourced the highest concentration of omega 3 fats available (they're from Norway) and manufactured their Lion Heart fish oil to meet the five star rating of the International Fish Oil Standards programme. A single teaspoon of this fish oil (which is flavoured by lemon and - hand on heart - tastes really rather good) delivers 3,135mg of EPA and DHA. 

Bare Biology wants some welldoing.org users to try it and see the difference. Retweet this story on Twitter or like the Welldoing page and share the post on Facebook and you may be one of five people who will receive a 150ml bottle. As it costs £47.50, this is great news! Otherwise, you can buy it direct from the website.
