it’s difficult to determine causation/correlation in this instance. some studies have shown that there may be a correlation between creatine and high blood pressure but there may not be enough evidence yet to support causation. a function of creatine is that it can withhold water in your muscles; and having more water in your body can raise blood pressure. for this reason diuretics (water pills) for example are commonly prescribed to alleviate high blood pressure by eliminating excess water and sodium from your body. accordingly it makes sense to think that creatine could raise blood pressure. i would encourage the individuals that you speak with to discontinue supplement use while monitoring any changes in their blood pressure. there can be many factors that influence blood pressure but if they discontinue supplement use and don’t notice any change in blood pressure after some time then creatine may not be the culprit. regardless if they already have high blood pressure supplementation is not recommended because both creatine and high blood pressure can cause kidney problems. excess protein in your diet can also cause kidney problems as well. it may just be prudent to discontinue supplement use altogether as long as their blood pressure isn't within normal limits. of course i would always encourage that you suggest that they speak with their doctor first before taking any supplements. my response is also just for learning purposes and is not meant to replace medical advice from a physician. read more about creatine here.
