high bun = high protein diet or high creatine levels if taking them, in lamens turns your kidneys are trying to assimulate protein waste. What may help here is to the added b-6 from the ZMA to help digest the extra protein. Or what also can help if you take a digestive enzymes mixture with heavier meals to add digestion. Or simple add some bromolaine to aid in the extra protein digestion. Your body has an enzyme bank and once it gets depleted then you run into major problems. Salting foods with sea salts also kicks up your digestive enzymes as well and is probably the cheapest easiest solution. People do not take alot of supplements because you get them from your food. Problems people run into is when they start malabsorbing nutrient due to stressful life styles then one must supplement what they may be lacking.
Rule of thumb : do not go supplementing with huge amounts of vitamins and minerals other wise your going to cause imbalances in other nutrients as well. unless supervised by a trained phyisican for a specific aliment
example
too much zinc cause a imbalance in copper, iron, calcium and blood tests are not accurate means of measuring minerals in the tissue. In order to see what is really going on you need RBC or plasma levels for true nutrient readings. Serum can give indicators, but can be deceptive becuase body has make up systems which will keep certain readings with in a tight range.
multivitain/mineral -lunch time
calcium supplement - another meal
before bed extra zinc if you are taking it. Zinc no more then 40 mgs total unless medically supervised
alot of people take vitamins at breakfast and it is not best to reason being most breakfast will interfer with abosrption of over 50% of vitamins. Alot of people do not know this. Ask your self this "why are people so lacking in certain nutrients, but they take a multivitamin" coffee and oatmeal bind have whats called phylates in them that bind to several minerals and you piss them out never being absorbed. i found out the hard way of this !!
Homocysteine information and you can see how zinc is linked as well as b-6 in the reactions
