Hello, Thank you for asking at HCM. I carefully read your question and understand your concern. Generally a healthy adult that is having normal balanced diet (fruit and vegetables, dairy products and meat) takes enough vitamins for the day and has not need for extra supplements. Many supplements are not well studied and on the other hand are a stress for the liver which is the organ that has to metabolize them. Omega supplements were thought to improve cardiovascular system and reduce ateriosclerosis risks and were used regularly for a long time but studies have not found them to really effect the cardiovascular risks if taken as supplements. Surely you will need to take them daily out of a balanced diet that I mentioned above. If you do not have a certain diagnosed vitamin deficiency (by a doctor because of tests that confirmed it) I would recommend you: 1. Stop any supplements you are taking- it is a stress for your liver and you do not really need them if you have a good balanced daily diet. 2. Make sure you do take daily fruit and vegetable (6-10 portions a day), daily dairy products, meet twice a week and fish 2 twice a week. Make sure you drink well during the day- it is a healthy habit. 3. To have a healthy heart watch you diet, make sure your BMI is 20-25, exercise 30 minutes every other day, be active, avoid fat and extra sugar in diet, avoid alcohol and smoking, treat well chronic conditions you might have like hypertension and diabetes. 3. Bruising can happen spontaneously in elderly but should be in areas prone to trauma like forearms and legs. 4. If bruising is in areas that do not have trauma than you need to have tests done to check how the coagulating factors, PLT and other indexes in blood are doing. Standard is bleeding time, coagulation time, complete blood count, PLT level check by microscoy and liver function tests like ALT, AST, protein in blood. 5. The next steps should be directed by results of the tests in step 4 I hope this answers to your question and is helpful to you Best regards
