Calcium type affects clot risk
Thrombotic Complications Associated With Right Atrial Lines in Neonates and Infants Undergoing Cardiac Surgery. Is Calcium Chloride a Culprit?
High relevance to thrombotic outcomes
We explored the impact of different calcium infusions on clotting risks in neonates undergoing cardiac surgery. Our study involved analyzing data from 135 babies who received either calcium chloride or calcium gluconate during their treatment.

The findings highlighted a significant concern: when using calcium chloride, the incidence of thrombotic events was notably higher compared to those treated with calcium gluconate. Specifically, the odds of experiencing a blood clot were over three times greater in patients given calcium chloride.

With an overall thrombus occurrence of 9.9%, we observed that only 4.6% of the group receiving calcium gluconate developed such complications compared to 15% in the calcium chloride group. The evidence suggests that switching from calcium chloride to calcium gluconate could potentially reduce the risk of harmful blood clots in these vulnerable patients.

Calcium aids rapid blood clotting
Zeolite firmly anchored regenerated cellulose aerogel for efficient and biosafe hemostasis.
Calcium's beneficial role in treatment
We explored the role of calcium in promoting blood coagulation using a new zeolite-embedded regenerated cellulose aerogel (Z-RCA). This innovative hemostatic agent was designed to minimize common issues seen with previous zeolite-based products, like heat-induced tissue damage and unwanted blood clotting elsewhere in the body.

Our results showed that this aerogel effectively absorbed blood while releasing calcium ions, which play a crucial role in the blood clotting process. By combining the properties of zeolite and the calcium-releasing ability of the aerogel, we found that Z-RCA not only facilitated quicker blood clotting but did so safely, with less risk of adverse effects.

In animal trials, we observed that Z-RCA stopped bleeding faster than existing options like Quikclot and notably reduced blood loss by over 62%. This combination of effectiveness and safety makes Z-RCA a promising solution for achieving efficient hemostasis during emergencies.

Stable blood counts
It works perfectly! I've trusted this brand for three years. I received it as guided by a reproductive specialist. For three years, I have been consistently using it. It absorbs well and maintains stable blood counts.

Strengthened enamel
Good calcium. Calcium Hydroxyapatite is regarded as one of the finest forms of calcium in terms of bioavailability and safety. It is almost fully absorbed by the body, does not accumulate on the walls of blood vessels, and does not contribute to stone formation. I took two capsules after dinner for a month; my enamel has strengthened, and tooth sensitivity has vanished.

Child development support
Calcium is essential for a child's normal development. It aids in forming short-term memory and regulates the acid-base balance and heart function, as well as blood clotting.
