Description
What Calceos 500mg/400IU Chewable Tablets Are and What They Are Used For
Calceos 500mg/400IU Chewable Tablets contain calcium carbonate and colecalciferol (vitamin D3), two nutrients essential for maintaining normal bones, teeth and muscle function. Calcium and vitamin D work together – vitamin D contributes to the normal absorption and utilisation of calcium in the body.
Calceos is recommended for:
-
Supporting calcium and vitamin D deficiency, particularly in older adults
-
Use alongside osteoporosis treatments
-
Situations where there is an increased risk of low calcium or vitamin D levels
Calcium & Vitamin D Deficiency
Calcium and vitamin D are essential for bone strength, healthy muscle function and overall wellbeing. Deficiency can occur due to ageing, low dietary intake, limited sunlight exposure, certain medical conditions or reduced ability to absorb nutrients.
Common signs of low calcium or vitamin D levels include:
-
Muscle weakness or cramps
-
Bone discomfort
-
Fatigue
-
Increased risk of falls in older adults
-
Low mood (linked to low vitamin D)
Supplements such as Calceos can be advised by healthcare professionals when deficiency is confirmed or suspected.
