Mate, how can we possibly answer this? We have no idea of what the other supplements are, or anything about your physiology, or even your age. Come to that, since Internet queries are anonymous, we don't know your gender. We don't know what medications (prescription or OTC) or legal/illegal drugs (e.g., alcohol) you may be taking, and even if we did, because there is effectively *NO* quality control or clinical testing of "supplements", no one truly knows what the interactions might be. From your question, we can't even discern what the purpose is for which you are taking supplements. Is it a matter of your general health and wellness? Is it about sports performance? If about sports, is it for rugby? If what you are looking for is some unqualified person to support the decision you already want to make, then - based on past answers to similar questions - someone (from context usually an American teenager) will tell you what you want to hear. But the proper answer is for you to consult your personal medical adviser, someone with specific knowledge of you and your health, and also with the professional training to understand what all these supplements are and how they may affect you. That advice is as relevant for a 35-year-old bodybuilder as it is for a 17-year-old rugby player; male or female. In fact, it is true for anyone. Mark L.
