Calcium carbonate is a highly effective source of calcium, essential for maintaining strong bones and teeth. It is a commonly used form of calcium in supplements due to its high elemental calcium content. This ingredient is well-absorbed when taken with food, enhancing its effectiveness.
Risks
Excessive intake may lead to hypercalcemia, which can cause kidney stones and impaired absorption of other minerals.
Benefits
Provides essential calcium for bone health and supports various physiological functions.
CholecalciferolVery Good
Cholecalciferol, or Vitamin D3, is crucial for calcium absorption and bone health. It is the preferred form of Vitamin D due to its superior bioavailability compared to Vitamin D2. This ingredient also supports immune function and overall health.
Benefits
Enhances calcium absorption and supports bone and immune health.
MaltodextrinNeutral
Maltodextrin is a polysaccharide used as a filler or thickener in supplements. It is derived from starch and is highly processed, but generally recognized as safe. It provides no significant nutritional value but aids in the manufacturing process.
Risks
May cause spikes in blood sugar levels, particularly in individuals with insulin sensitivity.
Croscarmellose SodiumNeutral
Croscarmellose sodium is a disintegrant used to help tablets dissolve and release their active ingredients. It is considered safe and effective for this purpose. This ingredient is commonly used in pharmaceuticals and supplements to enhance bioavailability.
Benefits

Benefits
Enhances the stability and controlled release of the supplement.
Medium Chain TriglyceridesGood
Medium chain triglycerides (MCTs) are fats that are rapidly absorbed and metabolized for energy. They are derived from coconut or palm kernel oil and are known for their potential to support weight management and energy levels. MCTs are often used in supplements to enhance the absorption of fat-soluble vitamins.
Risks
Excessive consumption may lead to gastrointestinal discomfort.
Benefits
Supports energy metabolism and enhances the absorption of fat-soluble nutrients.
