The product is found useful for the following medical conditions

We examined a group of five patients undergoing long-term adefovir dipivoxil treatment for chronic hepatitis B.

All patients displayed low phosphate levels and reported difficulties walking, among other issues. After stopping the treatment, we focused on phosphate replacement and potassium-citrate therapy.

Encouragingly, after six months, participants experienced significant relief from bone pain, and some even regained the ability to walk independently.

Constipation details

Calcium citrate reduces constipation risk

Naciu AM, Tabacco G, Bilezikian JP, Santonati A, Bosco D, et al. Calcium Citrate Versus Calcium Carbonate in the Management of Chronic Hypoparathyroidism: A Randomized, Double-Blind, Crossover Clinical Trial. J Bone Miner Res. 2022;37:1251. doi:10.1002/jbmr.4564

We examined how calcium citrate affects constipation in patients with chronic hypoparathyroidism. In a randomized, double-blind study involving 24 participants, we found that those taking calcium citrate experienced significantly less constipation compared to those on calcium carbonate. Although both treatments maintained similar serum calcium and phosphorus levels, calcium citrate showed a favorable reduction in urinary oxalate excretion. However, there were no changes in overall quality of life scores. More extensive studies are needed to further assess these outcomes.

I tried a calcium carbonate supplement that caused constipation, but these do not induce that issue. This allows me to take calcium as per my doctor's recommendations, making me very happy!

Irritable Bowel Syndrome details

Perfect shape! I drink it twice a day, and I truly appreciate the results. I’ve forgotten about the cramps and feel calmer and less irritable.

Menopause details

Women experiencing menopause face significant calcium loss, and normal food may not sufficiently replenish it. Therefore, it's advisable to take calcium supplements.

Chronic Fatigue Syndrome details

Calcium has become vital in my daily health regimen. Since incorporating it, I’ve noticed my bones and teeth becoming stronger, and my nails no longer break or peel. Most impressively, muscle weakness and fatigue have vanished, leading to a significant enhancement in my overall well-being. Calcium provides me confidence in supporting my body from within—it’s not merely a vitamin but essential for an active and healthy life.

Frozen Shoulder details

Joint pain alleviated

Most Useful Review

I take a citrate form of calcium due to my sensitive stomach, which is well-tolerated as long as I'm not on an empty stomach. While breastfeeding, I struggled with wrist and shoulder joint pain, but after a month of use, it has subsided. This was recommended by my doctor and has made a noticeable difference.

My husband had a heart attack and quadruple bypass surgery. The ingredients in this product align perfectly with what the doctor recommended. Although it's a large pill, it seems uniquely suited for his recovery needs, and I haven't found a comparable alternative.

Urinary factors impact kidney stone risk

Ferraro PM, Taylor EN, Curhan GC. 24-Hour Urinary Chemistries and Kidney Stone Risk. Am J Kidney Dis. 2024;84:164. doi:10.1053/j.ajkd.2024.02.010

We undertook a thorough analysis of 24-hour urine collections from over 6,200 participants to explore how various urinary factors contribute to kidney stone formation.

Our findings revealed that higher levels of urine volume, citrate, potassium, magnesium, and uric acid were linked to a lower risk of developing stones. Conversely, increased levels of calcium, oxalate, phosphorus, and sodium were associated with a higher risk.

Interestingly, urine acidity did not seem to play a role. Our research highlighted the complexity and varying importance of these urinary factors regarding their relationship with stone formation.

Prevents kidney stones

Best Absorbable Form of Calcium Why did I choose this particular calcium? Because my dietitian advised me to take calcium citrate as it is the least likely to contribute to the formation of kidney stones. This is the most optimal form of calcium. Additionally, the composition also contains vitamin D2, zinc, copper, magnesium and manganese. However, consider this if you are consuming other supplements to avoid overdose! It is recommended to take two tablets daily, ideally at different times. For instance, in the morning and afternoon. At night - it's not recommended, due to rapid mineral salt release from the body. Adults only should use this. The only drawback for me is the size of the oblong-shaped tablets - 2.4 cm long. I also struggle to swallow pills, needing to drink and eat to prevent choking on them. If my review is helpful, please like it 👍🙂

Sleep Apnea details

I'm taking one tablet at a time, both morning and night, and since it's calcium citrate, it's absorbed well. I sleep well at night, and my anxious mind feels calm.

Yeast Infection details

Safeguards against infections

Most Useful Review

The use of calcium citrate does not cause kidney stones, making it a safe option for health. It's beneficial for urinary tract diseases as it alkalises the urine, thereby creating an unfavourable environment for the growth of yeast infections and other genital inflammations.

Dysmenorrhea treatment: Magnesium vs. COC

Gök S, Gök B. Investigation of Laboratory and Clinical Features of Primary Dysmenorrhea: Comparison of Magnesium and Oral Contraceptives in Treatment. Cureus. 2022;14:e32028. doi:10.7759/cureus.32028

We explored the treatments for primary dysmenorrhea by comparing magnesium citrate and combination oral contraceptives. Our study involved 172 women with dysmenorrhea and a matched control group.

While both treatments significantly reduced pelvic pain, those using oral contraceptives experienced greater relief and a decreased need for painkillers. Interestingly, we also found lower levels of calcium and vitamin D in patients with dysmenorrhea. Magnesium citrate did provide some relief, but it wasn’t as effective as oral contraceptives.

Absorbable calcium! As a bariatric patient, taking calcium is vital for me. I choose calcium citrate for its versatility; I can take the tablets at any time. I take two tablets daily, which lasts me 125 days. The capsules are large but easy to swallow. I take tests every three months, showing excellent calcium levels. My dentist has noted my stronger teeth. I happily recommend this product and even bought an annual supply for my mother, especially to help prevent fractures in postmenopausal women.

Calcium citrate improves bone density

Reid IR, Mason B, Horne A, Ames R, Reid HE, et al. Randomized controlled trial of calcium in healthy older women. Am J Med. 2006;119:777.

We conducted a well-designed trial involving 1,471 healthy postmenopausal women to explore the effects of calcium citrate on bone density and fracture rates over five years.

While we found that calcium significantly improved bone density, with noted benefits in spine and hip areas, the impact on actual fracture prevention was less clear.

Notably, longer-term compliance was an issue, which may have diminished its effectiveness. Ultimately, while calcium citrate appears to help with bone health, its role in preventing fractures remains uncertain.
