Take a teaspoon (5 ml) with lunch or breakfast; the fat in the meal improves the absorption of the fat-soluble vitamins D and A.
Best preparation methods
Choose molecularly distilled brands free of mercury and heavy metals, preferably with a natural flavour such as lemon to mask the fishy taste, and always keep it in the fridge after opening.
