Kidney Disease

Berberine has meta-analysis evidence for glucose and lipid markers, but it carries important medication, pregnancy, breastfeeding, antibiotic, transplant, and infant cautions. | Cinnamon is studied for glucose and lipid marker contexts, but species, coumarin content, liver disease, anticoagulants, and diabetes medications matter. | Added sugars can crowd out nutrient-rich foods and are limited in dietary guidance.

7 linked items - Diabetes, prediabetes, hypoglycemia, pregnancy, kidney disease, and glucose-lowering medications require clinician guidance. Supplements can alter medication effects and lab markers.

Glucosamine is widely used for cartilage and joint contexts, but product form, allergy, medication, and evidence-quality issues need clearer claim-level review.

6 linked items - Bone density loss, fractures, kidney stones, kidney disease, anticoagulant use, and chronic joint pain require individualized medical guidance.

Constipation/gas/bloating | Kidney stones in susceptible people | Medication spacing

Calcium - Supplements, Antacids, Some fortified foods

Constipation | Kidney stones | High blood calcium | Confusion or weakness in hypercalcemia | Reduced absorption of iron or zinc when intakes are high

mineral - Calcium supplements need caution with kidney stones, kidney disease, high calcium levels, and some medications.

EPA/DHA omega-3 products affect triglyceride and cardiovascular-marker discussions, but dose and bleeding-risk context matter. | Garlic supplements may modestly affect cholesterol in some studies, but effects are small compared with lipid-lowering medicines and bleeding risk matters. | Whole flaxseed and flaxseed lignans have more cholesterol discussion than flaxseed oil; product type matters. | Green tea and green tea extract are discussed for cholesterol, but concentrated extracts need liver-safety and caffeine context.

6 linked items - High cholesterol can require medication and cardiovascular-risk management. Supplements should not replace prescribed lipid-lowering therapy or delay risk evaluation.

allergy | kidney disease

Bone, Joint & Cartilage - Evidence: promising

kidney disease | pregnancy/breastfeeding | complex medical conditions

Brain & Cognitive - Evidence: established use

blood pressure | low potassium | heart disease | kidney disease | pregnancy/breastfeeding

Herbs & Botanicals - Evidence: traditional use

Supplement claims are product-specific | Review kidney disease and medication spacing contexts

Magnesium - Supplements

Diarrhea | Nausea or abdominal cramping | Low blood pressure | Lethargy or confusion | Irregular heartbeat risk with very high supplemental doses or kidney disease

mineral - Supplemental magnesium can accumulate in kidney disease and can interact with several medications.

Review medication and kidney disease contexts

Magnesium - Supplements

6 linked items - Sports supplements are not automatically appropriate for pregnancy, kidney disease, heart rhythm issues, hypertension, medication-heavy contexts, or younger athletes.

Low calcium balance concern | Soft tissue calcification risk in kidney disease | Higher cardiovascular and bone concern when kidney function is impaired | People with kidney disease should seek clinician guidance for high phosphate levels, weakness, bone pain, or calcification concerns.

mineral - Phosphorus and phosphate intake are especially important in kidney disease.

Muscle weakness | Numbness or tingling | Nausea | Dangerous heart rhythm changes, especially with kidney disease or certain medications | High or low potassium can cause dangerous heart rhythm changes. Seek urgent care for chest pain, fainting, severe weakness, or palpitations.

macromineral - Potassium supplements and salt substitutes can be dangerous with kidney disease or medications that raise potassium.

Digestive discomfort in some people | Can worsen management burden in advanced kidney disease if not clinician-guided | May displace other nutrient-rich foods when intake is extreme

macronutrient - Symptom reference

Magnesium is often discussed for leg discomfort or sleep, but restless-legs evidence is not the same as official magnesium intake guidance. | Caffeine may aggravate restless legs or sleep disruption in some people, especially later in the day. | B12 belongs in neurologic symptom review contexts, but restless legs should not be assumed to be a B12 issue without evaluation. | Folate supports red blood cell formation and neurologic context, but RLS symptoms require cause-based assessment rather than broad supplementation.

5 linked items - Restless legs symptoms should be evaluated for iron deficiency, kidney disease, neuropathy, sleep apnea, pregnancy, and medication triggers. Iron supplements should only be used after iron studies and clinician guidance.

High blood pressure risk | Fluid retention | Thirst | Higher cardiovascular and kidney strain when chronically excessive | Seek urgent care for confusion, seizures, severe headache, or suspected severe dehydration or hyponatremia.

macromineral - Sodium intake is clinically important for blood pressure, kidney disease, heart failure, dehydration, and hyponatremia risk.

Very high intakes can cause gastrointestinal symptoms and may be unsuitable for some people prone to kidney stones.

vitamin - RDA 90 mg/day

High blood calcium | Nausea or vomiting | Weakness | Frequent urination or dehydration | Kidney stones or kidney injury risk

vitamin - High-dose vitamin D can raise calcium levels and should be monitored when used above routine intake ranges.

Fat-soluble vitamin | High-dose supplements can exceed ULs | Review kidney disease, hypercalcemia, granulomatous disease, and medication contexts

Vitamin D - Skin synthesis from UVB exposure, Fatty fish, Egg yolk, Liver, Fortified foods, Many supplements
