Effects of Liposomal Encapsulation on Calcium Powder Absorption and Metabolism

April 12, 2024 updated by: YenPing, Lei, National Yang Ming University
Compared with traditional calcium supplements, liposome calcium can increase the bioavailability of calcium and reduce the waste caused by gastric acid destruction of calcium. This allows calcium to be released slowly in the intestines, reducing the risk of indigestion or other side effects caused by excessive intake at one time. Liposomal calcium can be taken orally directly. It does not need to be dissolved in water before taking like other calcium supplements, making it more convenient to use. Based on the above advantages, liposomal calcium is a relatively safe and easy-to-absorb calcium supplement, suitable for long-term use, and can meet the body's demand for calcium. According to the recommendations of the World Health Organization, the daily calcium intake for adults should be 1000-1300 mg. In Taiwan, the seventh edition of the revised reference intake of dietary nutrients for Chinese people recommends that the daily intake for adults should be 1,000 mg. The calcium dose used in this study was 500 mg. The purpose was to explore whether the sustained-release characteristics of liposome coating technology can improve the absorption rate after consuming calcium powder and achieve better bioavailability. It is expected that microlipids made by lecithin can Lipid calcium powder increases its maintenance time in the blood, thereby increasing the supplementary effect of calcium, and is an alternative to calcium supplements.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

General examination
Time Frame: Day 14 and 28
BMI(Body Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in metres squared) and blood pressure
Day 14 and 28

Time Frame: Day 14 and 28
Fasting blood glucose, triglycerides, total cholesterol, Blood urea nitrogen, Creatinine(Blood urea nitrogen (BUN) and creatinine tests can be used together to find the BUN-to-creatinine ratio (BUN:creatinine).
