What You Need to Know Before You Apply

What is the purpose of this trial?

Proton pump inhibitors (PPIs) are widely used for the control of gastric ulcer-gastritis, erosive esophagitis (gastroesophageal reflux disease), peptic ulcer disease (duodenal ulcer), and heartburn. Despite their efficacy, their use has been implicated in possibly causing fragility fractures (osteoporosis), hypomagnesemia (magnesium deficiency) and increased risk of chronic kidney disease (CKD). The current trial represents the investigators ongoing effort to discern whether these complications could be averted by effervescent calcium magnesium citrate (EffCaMgCit).

Will I have to stop taking my current medications?

The trial requires that you continue taking your proton pump inhibitor (PPI) at a similar dosage. However, if you are taking certain other medications like adrenocorticosteroids, diuretics, or regular magnesium supplements, you may need to stop. Other medications will be considered individually.

Is EffCaMgCit safe for human use?

Research on similar calcium and magnesium supplements shows they are generally safe for human use, with studies indicating they can be absorbed well and support bone health. However, specific safety data for EffCaMgCit in humans is not directly available from the provided studies. ^{1 2 3 4 5}

How does the treatment EffCaMgCit differ from other osteoporosis treatments?

EffCaMgCit is unique because it combines calcium and magnesium in an effervescent form, which may enhance absorption compared to other calcium supplements. This combination could potentially improve bone health by addressing both calcium and magnesium deficiencies, which are important for bone metabolism. ^{1 6 7 8 9}

What data supports the effectiveness of the treatment EffCaMgCit for preventing osteoporosis?

Research suggests that magnesium supplementation can promote bone formation and prevent bone loss, which may help in osteoporosis prevention. Additionally, higher calcium intake is associated with a reduced risk of osteoporotic fractures, especially when the calcium to magnesium intake ratio is balanced. ^{1 5 8 10 11}

38 meq (760 mg) Ca, 20 meq (243 mg) Mg, and 100 meq total citrate per day; designed to be added to 6 oz water for 1-2 minutes, to be dissolved/suspended before swallowing.

Group II: Placebo Placebo Group 1 Intervention

Each sachet of Placebo will contain microcrystalline cellulose, but no calcium, magnesium or citrate. Placebo will be added to 6 oz water for 1-2 minutes, to be dissolved/suspended before swallowing.

A study comparing calcium absorption in 15 young and 20 elderly women found that soluble calcium citrate and calcium gluconolactate-carbonate are better absorbed than solid calcium citrate, indicating they may be more effective for treating osteoporosis.

Both young and elderly women showed similar absorption patterns, with soluble forms leading to greater increases in plasma calcium and urinary calcium excretion, suggesting that these forms could be beneficial for improving calcium intake in older adults.

In ovariectomized rats, a higher magnesium diet (0.15%) led to lower calcium absorption but increased bone formation and reduced bone resorption, suggesting a complex role of magnesium in bone health.

Magnesium supplementation improved the dynamic strength of bones, as indicated by higher breaking force and energy in the femurs of rats on the higher magnesium diet, highlighting its potential benefits for postmenopausal bone health.

In a study of 48,584 postmenopausal women over a median follow-up of 10.1 years, higher daily calcium intake (>400 mg) was linked to a 40-50% reduction in the risk of osteoporotic fractures, particularly in those with a calcium/magnesium intake ratio of ≥1.7.

Additionally, high soy isoflavone intake (>42.0 mg/d) was associated with a reduced risk of fractures (HR 0.72) among women with a history of fractures, especially in those who were recently menopausal.

In a study involving 20 healthy women, magnesium supplementation did not significantly affect bone resorption markers or serum parathyroid hormone levels, suggesting it may not directly influence bone health.

However, magnesium supplementation led to a 31.1% increase in urinary magnesium excretion and a significant 23.5% decrease in fractional calcium absorption, indicating that while magnesium is excreted more, it may hinder calcium absorption in the body.

In a study of 2,038 older adults aged 70 to 79, higher magnesium intake from diet and supplements was linked to increased bone mineral density (BMD) in white men and women, suggesting a potential benefit for bone health.

Specifically, white women had a BMD increase of 0.04 g/cm2 and white men had an increase of 0.02 g/cm2 when comparing the highest to the lowest magnesium intake, while no such association was found in black participants, possibly due to differences in calcium regulation.

In a study involving 40 female rats over 12 weeks, magnesium (Mg) supplementation with adequate calcium (Ca) significantly improved bone mineral density, size, and metabolism without affecting calcium absorption.

The results indicated that Mg supplementation increased serum osteocalcin and decreased levels of C-telopeptide cross-links of type I collagen, suggesting enhanced bone formation and reduced bone resorption in rats with adequate Ca intake.

Magnesium Citrate (MC) bowel preparation for colonoscopies was found to be highly effective, with adequacy rates of 98.94% for screening and 99.29% for non-screening procedures based on a large sample of 19,173 patients.

MC is a well-tolerated and cost-effective option for bowel preparation, showing favorable results compared to other preparations in this extensive retrospective study.

In a study involving 20 healthy perimenopausal women, calcium citrate (CC) was found to have significantly greater bioavailability compared to calcium gluconolactate and carbonate (CGC), indicating it may be more effective for calcium absorption.

Both calcium salts increased serum calcium levels and urinary calcium excretion while reducing parathyroid hormone levels, but CC's superior absorbability suggests it could be the preferred choice for supplementation.

Calcium supplementation alone is not recommended for preventing fractures in the general postmenopausal population, but it may benefit those at risk with low dietary intake, requiring personalized approaches to avoid side effects.

Vitamin D supplementation is crucial for individuals at risk of fractures or vitamin D deficiency, while vitamin K2 and magnesium may support bone health, though evidence for their effectiveness remains inconclusive.

In a study of 31 postmenopausal women with osteoporosis, magnesium treatment led to a significant increase in bone density after one year, with 71% of participants showing improvements of 1-8%.

Compared to untreated controls, who experienced a significant decrease in bone density, the magnesium-treated group maintained their bone density over two years, suggesting that magnesium may be a beneficial intervention for postmenopausal osteoporosis.

In a study of 20 postmenopausal women, daily oral magnesium supplementation for 30 days significantly decreased serum levels of parathyroid hormone (iPTH), which is important for regulating bone metabolism.

The magnesium-supplemented group also showed increased serum osteocalcin and decreased urinary deoxypyridinoline levels, indicating that magnesium may help suppress bone turnover and improve bone health in postmenopausal women with osteoporosis.
