What Supplements Are Bad For Kidneys?

Getting enough nutrients every day is important for health. Nutrients give you the energy to complete daily tasks, build muscle, repair body tissue, prevent infection and maintain a healthy weight. The key nutrients are protein, calories, vitamins, and minerals. Your body needs all of these every day.

Most people get enough nutrients by eating a wide variety of foods each day. However, if you have kidney disease or kidney failure, you may need to limit some foods that would normally give you enough nutrients for good health. Also, kidney disease and kidney failure can change the way your body processes certain nutrients, so supplements can help ensure that youre getting all of the nutrients you need. Many supplements are available, but some are made just for people with kidney disease, diabetes, or kidney failure.

Its very important to check with your healthcare provider or dietitian before taking any supplements because some can actually be quite harmful to people with kidney disease or kidney failure. Your healthcare provider can tell you which specific supplements are right for you. Here are 8 key things to know:

Kidney Absorption And Storage

Your kidneys are responsible for filtering many nutrients out of the blood and lymph, including vitamin B-12 and other B vitamins, such as folate. In addition to vitamin conservation, tubular uptake by the kidneys is important for vitamin metabolism, storage and homeostasis, according to a study published in a 2006 edition of the medical journal “Renal Physiology.” For people with chronic kidney failure or acute kidney injuries, higher levels of vitamins and other nutrients typically are excreted in urine. Elevated levels of homocysteine in the blood indicate tioo little B-12 in your body. Homocysteine damages blood vessels and is linked to cardiovascular disease.

Too Much Of A Good Thing High Doses Of Vitamin D Can Lead To Kidney Failure

Canadian Medical Association Journal
A 54-year-old man, after returning from a trip to Southeast Asia where he spent much of his holiday sunbathing, showed increased levels of creatinine, suggesting kidney damage or malfunction. After referral to a kidney specialist and further testing, it was discovered that he had been prescribed high doses of vitamin D by a naturopath, who recommended a dose of 8 drops every day. Over 2 ½ years, the patient, who did not have a history of bone loss or vitamin D deficiency, took 8-12 drops of vitamin D daily, totalling 8000-12,000 IU. As a result, he had very high levels of calcium in the blood, which left him with significant kidney damage.

In patients with severe sepsis and septic shock treated with colistin according to a modified pharmacokineticspharmacodynamics -based dosing strategy, Dalfino et al. identified baseline renal impairment and older age as strong predictors of AKI occurrence.

What Is Vitamin C

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is critical to tissue growth and repair in our bodies. Vitamin C helps to heal wounds, form scar tissue, maintain structure of bones and teeth, and absorb iron. Signs of vitamin C deficiency, commonly known as scurvy, include leg weakness, easy skin bruising, and swollen gums. Vitamin C deficiency is relatively uncommon in the United States and Canada because many food items such as juices are fortified with vitamin C. Vitamin C is found naturally in foods such as oranges, guavas, sweet peppers, grapefruits, and kiwis.

Vitamin B Pantothenic Acid


Pantothenic acid, also known as vitamin B, assists in the process of creating and breaking down fatty acids. Making these fatty acids is essential for humans and helps us create our own cholesterol, store energy, and more.

Forms of Pantothenic Acid

About 85% of pantothenic acid in food is in the form of CoA or phosphopantetheine. Your body then breaks it down and shifts around the molecules to create a usable form for itself to help carry out necessary bodily functions.

The good bacteria in your gut, known as the microbiome, also create pantothenic acid but not in significant amounts.

Some dietary supplements contain pantethine, which is a byproduct of pantothenic acid and is commonly marketed as a way to lower cholesterol.

Recommended Intake and Deficiency

The adequate intake for pantothenic acid for adult men and women 14 years and older is 5mg per day. Since pantothenic acid is found in such a wide range of foods, deficiency is uncommon, especially in the US.

Deficiency is mostly reserved to those who are experiencing overall severe malnutrition and is accompanied by other vitamin and mineral deficiencies. A deficiency presents itself with numbness and burning in extremities, headache, fatigue, and irritability.

Tolerable Upper Level Intake

Drug-Nutrient Interactions with Pantothenic Acid

Pantothenic acid may alter the effects of the medications listed below. Consult with your doctor before beginning a new supplement routine.

Eating Healthily And Monitoring Your Diet

An unhealthy diet high in sugar and sodium can damage much more than your waistline, as overweight or obese people are at much higher risk of diabetes, heart disease and kidney disease. In order to support healthy kidneys, you should try to eat a low sodium diet with plenty of fresh fruits and vegetables such as whole grains, blueberries, and fish.

Calcium: The Excess Settles In Your Arteries

Calcium is essential for strong bones and a healthy heart, but too much is not a good thing. In fact, an excess of calcium, which is described by the NIH as more than 2,500 mg per day for adults ages 19 to 50, and more than 2,000 mg per day for individuals 51 and over, can lead to problems.

According to the Cleveland Clinic, Researchers believe that without adequate vitamin D to help absorb it, the extra calcium settles in the arteries instead of the bones.

In addition, an analysis of 10 years of medical tests on more than 2,700 people in a federally funded heart disease study, published October 10, 2016, in the Journal of the American Heart Association, suggested that taking calcium supplements may increase plaque buildup in the aorta and other arteries. In contrast, a diet high in calcium-rich foods, such as dairy products and leafy greens, appeared to be protective.

Get calcium from your diet if you can, advises Dr. Millstine, noting that research shows that calcium is better absorbed through food than through supplements.

Calcium deficiency, or hypocalcemia, may be detected by routine blood tests. If you have low calcium blood levels, your doctor may prescribe a calcium supplement.

Vitamin D: The Kidney Vitamin

Many Americans are deficient in an important vitaminvitamin D. The Centers for Disease Control and Preventionâs latest information has found that more than one-half of Americans of all ages have low levels of vitamin D. More and more information is pointing to how important vitamin D is to the body, especially the strength of bones.

In addition to maintaining healthy bones, newer research shows that vitamin D may also protect against heart disease. In fact, people with the lowest vitamin D levels had a 40% higher risk of cardiovascular disease in one study.

Talk with your doctor or dietitian before taking any vitamins that are not ordered for you. There are different types of vitamin D. Your doctor will be very specific about the type and amount you should be taking.

Why is vitamin D connected to the kidney? The kidneys are an important part of helping the body use vitamin D. Vitamin D comes from two sources in people. It could either be exposure to the sunâs ultraviolet B radiation. Or, it is absorbed from food or food supplements. The kidneys have an important role in making vitamin D useful to the body. The kidneys convert vitamin D from supplements or the sun to the active form of vitamin D that is needed by the body. With chronic kidney disease, low vitamin D levels can be found, sometimes even severely low levels. This may occur because injured kidneys are less able to convert vitamin D into its active form.

COVID-19 patients can become kidney patients.
