Can vitamin d deficiency cause muscle cramps even when calcium, magnesium, and potassium levels are good?

Can vitamin d deficiency cause muscle cramps even when calcium, magnesium, and potassium levels are good?

May be: Many issues are attributed to low vitamin D without necessarily strong evidence. However, if you suspect vitamin D deficiency, which is common, take about 2000 units of vitamin D3 daily. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.

What is a good mg amount of a potassium supplement to add daily if my potassium is low after hospital blood work? I'm getting severe leg cramps.

Potassium: Potassium comes in 10 mEq tabs. The usual daily replacement dose is 20-40 mEq/day. Usually magnesium is also low and needs to be repleted, too. Talk to your doc about having it prescribed and also have your lytes, K, Mg, etc rechecked in couple of weeks.

Hubby has severe cramps. Not on cholesterol s. Potassium level ok. What can help?

Maybe magnesium: Most people are deficient in magnesium, and very low levels can cause muscle cramping and irritable 'spazy' muscles. Best to get a magnesium product w/ several kinds of magnesium (chloride, citrate, chelate, etc).

What do you suggest if I'm taking potassium daily, however the cramps happen only at night fyi I am physically challenged. What could be the problem?

What do you suggest if I'm taking potassium daily, however the cramps happen only at night fyi I am physically challenged. What could be the problem?

Cramps: If you have cramps and are taking potassium (K) supplements, you may still have a low K. Get a blood sample and see what your K and magnesium (M) levels are. If your K and M blood levels are low, your K will not correct until the M level is normal. See a physician (P), get a blood test for K and M and discuss your problem with the P. Good luck.

Please help, how much potassium should I take to avoid getting running cramps?

None is needed: A low potassium is unlikely to be a cause of cramping. The serum potassium has to be very low before it causes muscle pain. These cramps are most likely related to dehydration. Hydrate before, during and after the run.

Can a potassium deficiency give you lef cramps?

Yes: Low potassium levels (known as hypokalemia) can often cause muscle weakness and cramps. Low potassium levels can occur after heavy exercise through poassium losses in sweat. This is why many sports drinks are fortified with potassium and athletes often eat foods rich in potassium in matches (for example, bananas).

Can advair cause low potassium and muscle cramps?

Possibly: A person who is taking Advair may experience low potassium and symptoms like muscle cramps, weakness, and abnormal heartbeat. Even if so, though, it’s *highly unlikely* that Advair’s the only cause. (Maybe a change in potassium or other electrolyte unrelated to Advair at all.) And while your lab work has likely been followed occasionally (once per year?), it may be good to contact your doctor.

I supplement with 100 mg potassium daily-- too much? When I eliminate it I get leg cramps.

I supplement with 100 mg potassium daily-- too much? When I eliminate it I get leg cramps.

Not too much: Potassium is usually dispensed as potassium chloride or potassium citrate. 100 mg usually refers to the weight of the salt. Physicians usually put patients on 10 to 20 meq of potassium as a supplement if needed. 10 meq of potassium = 1, 080 mg of potassium citrate or 750 mg of potassium chloride.

Would a person taking statin drugs that gets leg cramps be helped by k tab potassium pills?

No on 2 counts: Statins don't cause leg cramps and potassium doesn't cure them. Statins can cause generalized aching and reduction of dose is usually all that's required to correct that. Sometimes switching drugs is needed. Leg cramps are very common and generally related to overstretch and overuse. Stretching and warm-up exercises done daily helps most people.

I take potassium, drink water and gatorade 2 cups coffee but still cramp some days. Do I need to go to dr?

No self medication: Why you are taking potassium. If it is not prescribed by your physician potassium could be dangerous. You need a blood test to assess your electrolytes.
