Choosing The Best Calcium Supplements: What To Look For

Calcium is an essential mineral for maintaining strong bones and teeth, as well as supporting various bodily functions, including muscle contraction and nerve transmission. When dietary sources of calcium are insufficient, calcium tablets and supplements can be beneficial. However, with a wide array of calcium supplements available, it’s crucial to know what to look for when selecting the best one for your needs. In this article, we’ll explore the key factors to consider when choosing calcium supplements.

Calcium type

There are different forms of calcium used in supplements. The most common types include calcium carbonate and calcium citrate:

Calcium carbonate

This form contains a higher percentage of elemental calcium and is often less expensive. It is best absorbed when taken with food, as stomach acid aids in its absorption.

Calcium citrate

This form can be absorbed well with or without food, making it suitable for people with reduced stomach acid production or those who experience gastrointestinal discomfort with other forms of calcium.

The choice between calcium carbonate and calcium citrate depends on your individual preferences and needs.

Elemental calcium content

When evaluating calcium supplements, check the label for the amount of elemental calcium present in each serving. This value indicates the actual calcium content you will receive. For example, calcium carbonate may contain around 40% elemental calcium, so a 1,000 mg tablet would provide approximately 400 mg of elemental calcium.

Absorbability

The absorbability of calcium supplements can vary based on the type of calcium and the presence of other nutrients. Some calcium supplements include vitamin D, which aids calcium absorption, while others contain magnesium or vitamin K, which may also support bone health.

Dosage and timing

Consider your daily calcium requirements and how many servings or pills you’re willing to take. The recommended daily intake of calcium for most adults is around 1,000 to 1,200 mg. Determine if the supplement’s dosage aligns with your needs and lifestyle. Additionally, some people prefer to split their calcium intake into multiple doses throughout the day for better absorption.

Bioavailability

Calcium supplements vary in their bioavailability, which refers to the extent and rate at which the body can absorb and use the calcium. Factors such as particle size, formulation, and the presence of other nutrients can influence bioavailability.
