Spend 60-70% of your time cycling (i.e. for every 10 hours training cycle 7 hours run 2 hours and swim 1 hour) This is only a very basic guide line for injury prevention and you will get some cross over in fitness, the better you are on a bike your ironman marathon will be easier to complete.
People with liver disease and high alcohol intake may be at risk for liver toxicity from vitamin A supplementation. Vitamin A toxicity may lead to intrahepatic cholestasis, where bile cannot flow from the liver into the intestines. Vitamin A may cause low blood pressure. Caution is advised in people with low blood pressure or in those taking drugs or herbs and supplements that lower blood pressure.
Hi, thiamine or vitamin B1 is a water soluble vitamin, meaning that even though you may be having a high level now,it will soon be excreted from the body via the kidney. So, thiamine is not toxic in high concentrations.The normal blood thiamine level is 75 to 185 nmol/L. There is no such disease associated with a high blood B1 level as it is not dangerous. It is the deficiency of thiamine that causes disease. If you are taking thiamine supplements, you can reduce/ stop it. I hope my answer is helpful to you.
