I suspect that this type of thing is very individual, but reckon that its worth a shot for those not getting good results from there potassium tablets (or whatever you're using) A good idea is to bave a basic blood test done, have them check mineral levels, some people have lower levels of one or another. If one is low, or maybe a low normal, then you might want to suppliment that when riding, your doctor can tell you whether it's better to take a suppliment before, during or after a ride. If your *really* concerned about during rides, tell your doctor, maybe get a blood draw done, go ride a century, then stop back at the lab, for another blood draw, then run the mineral panel on both, you and your doctor can then look at both sets of values and determine what (if anything) you need, and how much.

You can die from lack of Potassium, usually from a heart attack. The thing is, you just don't lose that much potasium in your sweat. Sodium losses are about 20 times the potasium losses. Partly this is because 98% of your potasium is inside of cells. On the other hand, about 90% of your sodium is outside of the cells. This is true of all lifeforms on earth. One consequense of potasium being intracellular is that any time you eat food composed of cells you are getting potasium. This includes any fruits, vegetables, or muscles you eat. It is not hard at all to get plenty of potasium in your diet. People who get their potasium down low enough to have symptoms almost always have something else going on, such as diuretic use, prolonged diarrhea or vommiting, certain types of kidney disease, etc. The situation with sodium is different because the regulation of sodium and water are intimately connected. It is easy to affect sodium concentration by adjusting water intake. I don't know if coroners look for this but it is a well known fact that doctor who prescribe diuretics for their patients with high blood pressure also tell them to take Potassium supplements. Pretty much if you come within ten feet of a hospital you are going to get your potassium checked. (It's cheap too.) Some characteristic stuff happens when potassium gets really low, a death would be hard to miss. You are correct, certain diuretics are the most common cause of low potassium, but that has nothing to do with a healthy person exercising. |

Yup- and that's why potassium-containing IV's in hospitals are supposed to be marked in a distinctive fashion, and full-strength IV potassium chloride is kept away from the ER. Otherwise, bad stuff happens: http://www.iatrogenic.org/fatalerr.html Jeff It's a big deal at the hospital I work at. The Joint Commission that accredits hospitals nationwide (http://www.jcaho.org/) has very strict rules as to where concentrated potassium can be kept in the hospital. I've also been told concentrated potassium is used for lethal injection. From Joint Commission website: Medication Error Prevention -- Potassium Chloride In the two years since the Joint Commission enacted its Sentinel Event Policy, the Accreditation Committee of the Board of Commissioners has reviewed more than 200 sentinel events. The most common category of sentinel events was medication errors, and of those, the most frequently implicated drug was potassium chloride (KCl). The Joint Commission has reviewed 10 incidents of patient death resulting from misadministration of KCl, eight of which were the result of direct infusion of concentrated KCl. In all cases, a contributing factor identified was the availability of concentrated KCl on the nursing unit. In six of the eight cases, the KCl was mistaken for some other medication, primarily due to similarities in packaging and labeling. Most often, KCl was mistaken for sodium chloride, heparin or furosemide (Lasix). Issue For Consideration: In light of this experience, the Joint Commission suggests that health care organizations NOT make concentrated KCl available outside of the pharmacy unless appropriate specific safeguards are in place. -- Let the bridges I burn light my way... |

A salt-rich meal might be: V-8, doritos and a turkey sandwich (turkey is also loaded with potassium, although potassium depletion isn't an issue). Fast food french fries are also a great source of salt (& potassium) but most can't tolerate the grease when riding hard. What's interesting to me is that my cravings during hot, humid, hard rides seem to be sodium and potassium foods. I didn't know french fries had any potassium, but I know they taste wonderful to me in those conditions. How about Pringles potato chips? That's something else that I seem to crave. And beer, of course. And, as mentioned, orange juice with salt mixed into it. From my table, it looks like 1 serving of Pringles has 100% RDA for Potassium, so does 32 fl oz of OJ, or a pound or so of bananas. While we're at it, I wonder what foods are rich in magnesium. I'd be interested to know if I crave those. Watermelon, almonds, chocolate, sunflower seeds... Funny thing about beer. I was doing a 400K (250 mi) ride, and all I could think of for the last several hours was a cold beer. I called my wife and begged her to bring a cold one (or 2) to the finish. When I got there I couldn't wait for it, but it was the worst tasting beer I think I've ever had, couldn't finish a single bottle. Same beer tasted fine the next day. |

Thanks for the info....I had big problems with cramps on two rides last year and ended up in the sag wagon. So, I'm going to try the magnesium this time. Try Tums/Rolaids/whatever. You can get them in almost any convenience store, even in the middle of nowhere. Matt O. |

A salt-rich meal might be: V-8, doritos and a turkey sandwich (turkey is also loaded with potassium, although potassium depletion isn't an issue). Fast food french fries are also a great source of salt (& potassium) but most can't tolerate the grease when riding hard. Well, V8, pretzels, and turkey sandwiches are definately some of my staples. Last year we had Hammergel as a sponsor for our big club ride. We got free samples of their electrolyte capsules. As a believer in real food vs. artificial yuppie power food, I had never tried such a thing. It sat around for months, but I tried it one day when I was feeling really bad. Well, the stuff is like magic. I felt much better, instantly. So I bought some more. I use it occasionally when I feel sick or overtired. It's great stuff. I recommend it. Their listed ingredients don't sound too magical. I just make up my own capsules 2/3 table salt, 1/3 bicarb. I've found that salt depletion isn't a problem until after 8-10 hr or so of hot, hard riding, an observation that squares with the theory given the amount of sodium reserves and sweat loss rate. The ingredients for Hammergel Electrolytes: Sodium Chloride 100 mg. Calcium (Chelate) 50 mg. Magnesium (Chelate) 25 mg. Potassium (Chelate) 25 mg. Vitamin B-6 (Pyrodoxine HCL) 6.6 mg. Manganese (Chelate) 1.6 mg. L-Tyrosine 50 mg. It looks like you can get all that in Tums or whatever. Someone told me the B-vitamins in Hammergel are what makes the difference. Matt O. |

Well, it's about 5x the RDA for B-6. I don't know what the science is supposed to be, people have been hustling B-vitamins for decades as a cure-all for fatigue. I think it's BS. You do need the salt if you sweat enough to blow through your 8 gr nominal (sodium) reserve. My home-made capsules are about 1 g of salt (400 mg sodium), and I take one every couple of hours after I get to the point where I start to lose my thirst (8-10 hr, typically of hot, hard riding). Those Hammergel caps, like Gatorade, just wouldn't do much for me. Heck, 12 fl oz of V-8 is 1 g of sodium (2.5 g salt). |

So, I'm going to try the magnesium this time. Some people say potassium, some say calcium, now it's magnesium. You have to diferentiate between "medical" cramps (which may be an ion imbalance) and "exercise induced cramps". EIC is purely the result of fatigue. There's no magic pill or food. You can only train for endurance. The harder you push muscles, the faster you accumulate fatigue. You can get the most out of your current level of fitness by keeping your muscular level of effort very uniform. For most people that means not getting carried away and going out too fast and backing off to a comfortable pace during climbs. A HRM can be useful to keep an eye on your average effort level and help to pace yourself. |

I only put that in there as a maybe, since some people must be exercising to lose both weight and high blood pressure. I am borderline myself at 130/90 so I only sometimes take Atenolol/Tenormin which lowers BP by about 10 points but also put my pulse down that much, a side effect I don't mind while relaxing. Caution with all meds, vitamins, and foods. Bill Baka |
