The main and most common problem which can be associated with taking Vivioptal is nausea and sickness. Other reported side effects include headaches, slight hair loss and strange taste in the mouth. In terms of its benefits, it does provide you with a large selection of the nutrients that are required from your body on a daily basis. However, I would still not advise taking this product. It is thought that in capsule form you don't get the true benefits of the nutrients which it is supposed to contain. It is more advisable to consider why you want to take these tablets and then approach the issue head on. If you have a medical reason for wanting to try these capsules, then I would strongly advise talking to your GP about the problem and what can be done about it. They will be able to give you a properly tested medication to control the problem.
If you want to take this product as a vitamin supplement, I would advise firstly looking at your diet. Dietary changes can improve your health massively and fresh food is much better for you than the same nutrients in capsule form. You will see greater improvements by improving your diet than taking Vivioptal.
