Can I take together Vitrum D3 forte, Kerabione, Gold vit B forte, Omega 3 6 9, Magne B6 forte?

Yes, you can. These preparations do not interact with each other in clinically relevant ways that would preclude their combined use. I suggest, however, to consult a family doctor or dietitian whether the use of all these preparations is justified by nutritional deficiencies, which may result, m.in, from the diet or diseases that impair the absorption of nutrients. Please note that the more medications a patient takes, the greater the risk of adverse interactions between them. Already taking two drugs at the same time creates a risk of undesirable interactions at the level of 13-14 percent. If a patient takes 8 to 10 medications at the same time, it is almost certain that there will be interactions between them and there will be interactions that negatively affect the patient's health. This problem applies especially to the elderly, treated for several diseases at the same time.
