Across the lifespan, chronically low calcium intake has been linked to higher blood pressure, in part because calcium plays a key role in vascular smooth‑muscle contraction, sodium handling, and endothelial function. Large epidemiologic studies and randomized trials suggest that individuals with higher dietary calcium intake tend to have modestly lower systolic and diastolic blood pressures and may experience a small but meaningful reduction in risk of stroke and other cardiovascular events. The practical takeaway is that maintaining adequate daily calcium, alongside blood pressure control, exercise, and a heart‑healthy diet, may be an underutilized strategy to support vascular health and reduce long‑term cardiovascular risk. This medication is commonly used for Hypertension.

Some side effects may be linked to nutrient depletion caused by this medication.
Thiamine (vitamin B1) deficiency in patients with cardiovascular disease might be linked to two factors associated with loop diuretics: increased urine output, and cellular uptake inhibition. Loop diuretics can significantly increase urine volume and urinary flow rate, potentially leading to increased thiamine excretion through urine. Emerging evidence suggests loop diuretics may directly inhibit the cellular uptake of thiamine, further contributing to deficiency. Thiamine supplementation during loop diuretic therapy should therefore be considered.
Long-term use with Loop diuretics can come with potential side effects related to nutrient depletion. One such essential nutrient that these medications can impact is potassium. Potassium plays a critical role in various bodily functions including regulating blood pressure, ensuring proper balance of fluids and electrolytes within cells, and may contribute to a lower risk of developing kidney stones and bone loss. Potassium supplementation during loop diuretic therapy should therefore be considered.
Studies indicate that Loop diuretics can act as folate antagonists, potentially leading to a deficiency. This occurs because some diuretics inhibit the enzyme responsible for utilizing folate (folic acid) in the body. Research suggests a link between long-term diuretic use (over six months) and decreased blood folate levels while also showing a significant increase in damaging homocysteine levels. Folate supplementation during loop diuretic therapy should therefore be considered.
Loop diuretics can disrupt the kidneys' ability to reabsorb magnesium, leading to increased excretion of this essential mineral through urine. This potential depletion necessitates monitoring magnesium levels, especially in individuals undergoing long-term loop diuretic therapy. Supplementing with magnesium may be beneficial in such cases to help protect against a deficiency.
Calcium, crucial for strong bones and teeth, can be depleted by loop diuretics. These medications can unfortunately decrease calcium levels in the body. To protect against a deficiency and maintain optimal bone health, individuals taking loop diuretics may benefit from calcium supplementation.
