Typically, lecithin and fish oil pills are fat-soluble vitamins and are most effective if taken once a day, recommended at night before bedtime. However, fat-soluble vitamins such as lecithin and fish oil pills must be taken through fatty foods as a carrier in order to achieve the best and maximum bioavailability and absorption of fish oil pills and lecithin. Therefore, it is usually recommended to drink 200ml of warm milk before going to bed and then take lecithin and fish oil pills to avoid irritation of the gastrointestinal mucosa by the capsule walls. Taking lecithin and fish oil pills after drinking milk can release the oil content of the milk and break down the lecithin and fish oil pills, thus achieving maximum bioavailability.
