I use Udo's Choice Perfected Oil Blend, It contains flax oil as well as a few others (dunflower seed, sesame seed) and provides a proper balance of omega 3 and omega 6 fatty acids...
In all seriousness, a tablespoon or two of MQ Flax Oil (Refrigerated after breaking the seal, and shaken to distribute lignans) added to a triple threat 3/60 protien shake (vanilla OR choc) has been my regimen for the last year or so... I do my shakes with skim milk, 2 heaping scoops of powder, 1-2 tbsp of flax oil, 1 banana, and a couple of ice cubes. It cannot be beat and I've drank 2-3 a day for almost a year now. It has become part of the 6 meal a day routine Good for bulking OR cutting.
I just take it in the capsule form, and I don't taste anything. The only problem is you have to take more capsules to equal the amount of one teaspoon of the liquid flax oil.
