Hello and thank you for asking! It looks like you take great interest in your health.
It is generally advised to take supplements with a meal that has some healthy fats in it for best absorption of the fat-soluble vitamins (A,D, E, and K). Taking supplements with food also helps prevent an upset stomach. The omega-3 supplements do not replace a meal.
Unless you have a medical condition negatively affecting how your body absorbs certain nutrients, supplements are not required for optimal health. The best source of vitamins and minerals is from the foods we eat, and a balanced diet rich in a variety of wholesome, minimally processed foods usually provides our bodies with all the nutrients we need. Our recipes at EatFresh.org are a great resource! Perhaps you’d like to try this Vegetable and Salmon recipe, rich in antioxidants and omega-3 fatty acids.
On a final note, I highly recommend that you have your personal physician or registered dietitian review all the supplements you are taking to make sure you are not going over the safe, recommended daily amounts. Our bodies store the fat-soluble vitamins in our liver and fat cells and because of this, taking excess doses of these vitamins can be dangerous and toxic to the body.
In good health.
