PubMed indexes 8 records that name Calcitriol and Calcium together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Calcitriol and Calcium. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“Compared with a historical cohort, a PTH-guided protocol for Ca and calcitriol supplementation significantly reduces the postoperative hypocalcemia and hospital readmission rates in patients undergoing total thyroidectomy.”
Names both Calcitriol and Calcium in its title.
“These models suggest that in 'drug-naïve' state, 1,25(OH)2D along with moderately elevated phosphate increases the expression of pro-osteogenic molecules to induce BGC. Although normalization of calcium in 'conventionally treated' state increased the expression of Opg, Osterix, Alp, and Cav2, calcification increased only in a subset, akin to variation in progression of BGC in hypoparathyroid patients on conventional therapy.”
Names both Calcitriol and Calcium in its title.
Names both Calcitriol and Calcium in its title.
Names both Calcitriol and Calcium in its title.
“1. Long-term low-dose conventional calcitriol therapy in combination with calcium supplementation could slow the progression of secondary hyperparathyroidism in some hemodialysis patients. 2. Low-dose therapy with active vitamin D-metabolites is effective only in hemodialysis patients with baseline serum PTH levels below 500 pg/ml and without pronounced hyperphosphatemia.”
Names both Calcitriol and Calcium in its title.
“When rickets is present, calcium should be infused through a large vessel in doses high enough to produce normocalcemia, normophosphatemia, and suppression of parathyroid hormone. Only after radiologic healing has been observed can oral calcium therapy be introduced.”
Names both Calcitriol and Calcium in its title.
Names both Calcitriol and Calcium in its title.
“Antituberculosis drugs were started. The resolution of active tuberculosis was accompanied by normalization of serum calcium levels and by elevation above normal of serum concentration of parathormone.”
Names Calcitriol and Calcium together in an interaction, co-administration, or pharmacokinetic context.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Calcitriol, Calcium, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
NutriStack is an informational and organizational tool, not a medical service, and not a substitute for professional advice. Always consult a qualified healthcare professional before starting, stopping, or changing any supplement or medication.
