Calcium Glycerate
Calcium glycerate is a calcium salt of glyceric acid, a three-carbon hydroxy acid derivative, formed when calcium ions bind to glycerate molecules. No clinical evidence currently supports its use as a dietary supplement, and it should not be confused with the better-studied compound calcium glycerophosphate.
Origin & History
Calcium glycerate is a synthetic calcium salt of glyceric acid, existing as a white crystalline powder with the molecular formula C6H10CaO8·xH2O. It is chemically manufactured rather than extracted from natural sources, with commercial preparations typically achieving >98% purity.
Historical & Cultural Context
No historical or traditional medicine uses are documented for calcium glycerate, as it appears to be a modern synthetic compound. Unlike many mineral supplements, it has no recorded use in traditional systems like Ayurveda or Traditional Chinese Medicine.
Health Benefits
• No specific health benefits documented - no clinical trials or studies found for calcium glycerate • May theoretically provide calcium supplementation - based on chemical structure only, no evidence • Often confused with calcium glycerophosphate - a related compound with limited dental health applications • No proven efficacy for any health condition - absence of human research data • Potential calcium source - theoretical benefit only, no bioavailability data available
How It Works
Calcium glycerate would theoretically dissociate in the gastrointestinal tract, releasing free calcium ions (Ca²⁺) available for absorption via TRPV6 channels and calbindin-D9k-mediated transcellular transport in the duodenum. The glycerate anion, a metabolite of serine and glycolysis, would enter standard metabolic pathways upon absorption. However, no pharmacokinetic or mechanistic studies specific to calcium glycerate have been conducted in humans or animals to confirm bioavailability or receptor-level interactions.
Scientific Research
No human clinical trials, RCTs, or meta-analyses were identified for calcium glycerate in the research. The related compound calcium glycerophosphate has one Phase I clinical trial with unspecified indication, but no study details, sample sizes, or outcomes are provided. No PubMed PMIDs are available for calcium glycerate studies.
Clinical Summary
As of the current date, no published randomized controlled trials, observational studies, or preclinical animal studies specifically investigating calcium glycerate as a supplement have been identified in peer-reviewed literature. Its theoretical benefit as a calcium source is inferred solely from the known physiology of calcium absorption, not from direct experimental evidence. It is frequently confused with calcium glycerophosphate, a distinct compound that has limited evidence supporting reduced dental erosion in acidic food contexts. The overall evidence base for calcium glycerate is rated insufficient, and no dosing recommendations can be established.
Nutritional Profile
Calcium glycerate is an inorganic calcium salt formed from glyceric acid and calcium. As a mineral compound, it contains no macronutrients (zero protein, fat, or carbohydrates in functional supplemental doses). Calcium content is estimated at approximately 15-20% elemental calcium by molecular weight (molecular formula approximated as C3H5CaO4), though precise elemental analysis data in published literature is sparse. No vitamins, dietary fiber, or bioactive phytochemicals are present. The glycerate anion (derived from glyceric acid, C3H6O4) is a 3-carbon organic acid metabolite that theoretically participates in glycolytic and gluconeogenic pathways, but no quantified metabolic contribution data exists for the supplemental form. Bioavailability of calcium from this salt is undocumented in human trials; by analogy to other organic calcium salts (e.g., calcium citrate, calcium gluconate), organic calcium salts generally achieve 30-40% intestinal absorption, but this figure cannot be directly applied to calcium glycerate without supporting evidence. No standardized dosage form or concentration data is available in pharmacopeial references. The compound is not listed in major nutritional databases (USDA FoodData Central, EFSA nutrient databases), confirming absence of quantified nutritional profiling data.
Preparation & Dosage
No clinically studied dosage ranges are available for calcium glycerate as no human trials have been conducted. No standardized forms, extracts, or dosing protocols have been established. Consult a healthcare provider before starting any new supplement.
Synergy & Pairings
None identified - no synergistic ingredients documented due to lack of research
Safety & Interactions
No formal safety studies, toxicology reports, or adverse event data exist specifically for calcium glycerate in humans. As a calcium-containing compound, it may theoretically carry the general risks of excess calcium intake, including hypercalcemia, nephrolithiasis, and interference with absorption of iron, zinc, and magnesium when co-administered. Calcium salts broadly can reduce absorption of certain medications including tetracycline antibiotics, fluoroquinolones, bisphosphonates, and levothyroxine if taken simultaneously. Pregnancy and lactation safety cannot be assessed due to a complete absence of data.
