POTASSIUM: An Essential Slow Carb Vitamin

The goal for the average “Slow Carbohydrate Dieter” for preventing low levels of potassium is 20 mEq is typically taken daily. This can also be through dietary sources.

 

POTASSIUM

 

What is it?

Potassium is a mineral that plays many critical roles in the body. Food sources of potassium include fruits (especially dried fruits), cereals, beans, milk, and vegetables.
Potassium is used for treating and preventing low potassium levels. It is also used to treat high blood pressure and prevent stroke.
Some people use it to treat high levels of calcium, a type of dizziness called Menière’s disease, thallium poisoning, insulin resistance, symptoms of menopause, and infant colic. It is also used for allergies, headaches, acne, alcoholism, Alzheimer’s disease, confusion, arthritis, blurred vision, cancer, chronic fatigue syndrome, an intestinal disorder called colitis, constipation, dermatitis, bloating, fever, gout, insomnia, irritability, mononucleosis, muscle weakness, muscular dystrophy, stress, and with medications as treatment for myasthenia gravis.
Healthcare providers give potassium intravenously (by IV) for treating and preventing low potassium levels, irregular heartbeats, and heart attack.

Is it Effective?

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
The effectiveness ratings for POTASSIUM are as follows:

Effective for…

  • Preventing and treating low levels of potassium in the blood (hypokalemia).

Possibly Effective for…

  • High blood pressure. Potassium seems to lower systolic blood pressure (the top number in a blood pressure reading) by about 2-4 mm Hg and diastolic blood pressure (the bottom number) by about 0.5-3.5 mm Hg. Potassium seems to be most effective for lowering blood pressure in African Americans and people with low potassium levels or high daily sodium intake. In addition, potassium from food sources, but not from supplements, may help to prevent high blood pressure.
  • Preventing stroke. Potassium from dietary sources seems to decrease the risk of stroke. There is some evidence that foods providing at least 350 mg of potassium per serving and that are low in sodium, saturated fat, and cholesterol might help reduce the risk stroke. However, there is no proof that taking potassium supplements can decrease the risk of stroke.
  • High calcium in the urine (hypercalciuria).

Insufficient Evidence to Rate Effectiveness for…

  • Insulin resistance.
  • Heart attack.
  • Menopausal symptoms.
  • Fatigue and mood swings in early menopause.
  • Infant colic.
  • Allergies.
  • Headaches.
  • Acne.
  • Alcoholism.
  • Alzheimer’s disease.
  • Arthritis.
  • Blurred vision.
  • Cancer.
  • Chronic fatigue syndrome.
  • Colitis.
  • Confusion.
  • Constipation.
  • Skin problems.
  • Bloating.
  • Fever.
  • Gout.
  • Trouble sleeping (insomnia).
  • Irritability.
  • Menière’s disease.
  • Muscle weakness.
  • Muscular dystrophy.
  • Stress.
  • Myasthenia gravis.
  • Other conditions.

More evidence is needed to rate potassium for these uses.

How does it work?

Potassium plays a role in many body functions including transmission of nerve signals, muscle contractions, fluid balance, and various chemical reactions.

Are there safety concerns?

Potassium is LIKELY SAFE for most people when taken by mouth in amounts of up to 90 mEq of total potassium from the diet and supplements combined. Potassium can cause stomach upset, nausea, diarrhea, vomiting, intestinal gas, and other side effects.
Too much potassium is UNSAFE and can cause feelings of burning or tingling, generalized weakness, paralysis, listlessness, dizziness, mental confusion, low blood pressure, irregular heart rhythm, and death.

Special Precautions & Warnings:

Pregnancy or breast-feeding: Potassium is LIKELY SAFE when obtained from the diet in amounts of 40-80 mEq per day.
Disorders of the digestive tract that might alter the speed food and supplements pass through the body (GI motility conditions): If you have one of these disorders, do not take potassium supplements. Potassium could build up to dangerous levels in your body.
Allergy to aspirin or tartrazine products: Avoid potassium supplements that contain tartrazine.

Are there any interactions with medications?

Medications for high blood pressure (ACE inhibitors)
Interaction Rating = Moderate Be cautious with this combination.
Talk with your health provider.

Some medications for high blood pressure can increase potassium levels in the blood. Taking potassium along with some medications for high blood pressure might cause too much potassium in the blood.
Some medications for high blood pressure include captopril (Capoten), enalapril (Vasotec), lisinopril (Prinivil, Zestril), ramipril (Altace), and others.

Medications for high blood pressure (Angiotensin receptor blockers (ARBs))
Interaction Rating = Moderate Be cautious with this combination.
Talk with your health provider.

Some medications for high blood pressure can increase potassium levels in the blood. Taking potassium along with some medications for high blood pressure might cause too much potassium to be in the blood.
Some medications for high blood pressure include losartan (Cozaar), valsartan (Diovan), irbesartan (Avapro), candesartan (Atacand), telmisartan (Micardis), eprosartan (Teveten), and others.

Water pills (Potassium-sparing diuretics)
Interaction Rating = Moderate Be cautious with this combination.
Talk with your health provider.

Some “water pills” can increase potassium levels in the body. Taking some “water pills” along with potassium might cause too much potassium to be in the body.
Some “water pills” that increase potassium in the body include amiloride (Midamor), spironolactone (Aldactone), and triamterene (Dyrenium).

Are there any interactions with Herbs and Supplements?

Vitamin B12

Vitamin B12 can cause a temporary drop in the level of potassium in the blood. This is a concern for people who are receiving vitamin B12 as treatment for a condition called megaloblastic anemia. People who are getting extra vitamin B12 should be monitored to make sure their potassium levels aren’t going too low.

Are there interactions with Foods?

Foods that contain potassium

Taking potassium and eating foods that contain potassium might increase the risk of unwanted side effects, especially in people with kidney disease, or in people who are being treated with ACE inhibitor drugs or potassium-sparing diuretics. Potassium-containing foods include fruits (especially dried fruits), cereals, beans, milk, and vegetables.

Salt substitutes that contain potassium

Taking potassium and using salt substitutes that contain potassium might increase the risk of unwanted side effects, especially in people with kidney disease, or in people who are being treated with ACE inhibitor drugs or potassium-sparing diuretics.

What dose is used?

The following doses have been studied in scientific research:
BY MOUTH:
Potassium supplementation must be tailored for each person and based on the person’s serum potassium level, which should be maintained between 3.5-5 mEq/L.
The normal adult daily requirement and usual dietary intake is 40-80 mEq daily.

  • For preventing low levels of potassium: 20 mEq is typically taken daily.
  • For treating low levels of potassium: the common dose of potassium is 40-100 mEq or more daily, in two to four divided amounts.
  • For treating high levels of calcium: 1 mEq/kg is taken daily or four tablets of Urophos-K are taken twice a day.
  • For high blood pressure: the typical dose is 48-90 mEq daily.
  • For preventing stroke: dietary intake of approximately 75 mEq (about 3.5 grams of elemental potassium) daily may reduce risk.

Foods that contain at least 350 mg potassium can be labeled “Diets containing foods that are good sources of potassium and low in sodium may reduce the risk of high blood pressure and stroke.”

What other names is the product known by?

Atomic number 19, K, Potasio, Potassium Acetate, Potassium Bicarbonate, Potassium Chloride, Potassium Citrate, Potassium Gluconate, Potassium Glycerophosphate, Potassium Orotate, Potassium Phosphate, Potassium Sulfate.

Resources:

Also available & can be very convenient to use, are tablets of Potassium Gluconate 595mg (99mg Potassium = 2.53 meq K+). These are rather inexpensive, and I find more convenient to use for a Potassium supplementation. Especially when traveling.

I don’t understand the recommended dosages. In 4-Hour Body, Tim says, ” If you prefer pills, 99-milligram tablets with meals will do the trick.” Then, not a few paragraphs later he says, “Potassium (4,700 mg per day recommended for an average, healthy 25-year-old male).”

Can anyone explain this to me? Because now this site is saying yet another figure entirely!

Hey Jesse, I wondered the same exact thing! I think this article I wrote a few months ago will make your day: http://www.4hourlife.com/2013/01/20/potassium-milliequivalents-milligrams-and-4-hours-of-conversion-confusion/

Let me know if you are still confused, when I was researching this I questioned several of the doctors I worked with as well, and most of them didn’t even know the answer!
