Supplement name: Christopher's Original Formulas, Kid-e-Calc®, Calcium Formula, 2 fl oz Supplement scores: 7 Introduction & context: This liquid calcium supplement is marketed for children, providing 167 mg of calcium per serving from calcium carbonate and calcium lactate. It includes glycerin, water, and natural flavors. Priced at around $10 for a 4 fl oz bottle, third-party testing for purity is not publicly disclosed. Evidence summary: Limited human trials focus on calcium supplementation in children for bone health. A Cochrane review found modest benefits in bone mineral density, but data are sparse and long-term effects unclear. Studies often use doses (500-1000 mg/day) higher than this product's offering. Formulation & quality analysis: Calcium carbonate has moderate bioavailability, while calcium lactate is slightly better absorbed. The presence of glycerin may enhance palatability but adds sugar content. Lack of third-party testing raises concerns about contaminants like lead. Safety & interactions: Generally safe at recommended doses, but excessive intake can lead to constipation or kidney stones. No significant interactions noted, but caution with high-phytate foods. Personal experience after taking the product: Not applicable as this review is based on formulation and evidence, not personal use. Value & practicality: Provides a low dose of calcium, potentially insufficient for children's daily requirements (1000-1300 mg depending on age). Alternatives like fortified milk or cheese offer more calcium with better bioavailability. Overall verdict + score: Moderate efficacy with formulation concerns; situational use for children resistant to solid supplements. Score reflects mixed evidence and potential safety/quality gaps. Who it's for: Children needing minor calcium supplementation who prefer liquid form. Consider dietary sources first; consult a pediatrician for personalized advice.

Used As "Herbal Calcium" Replacement

Verified purchase

The grown-up version "Herbal Calcium" tincture was out of stock during the Covid times so I used this children version as a replacement for a while. It is okay and I did not recognize any difference in terms of effectiveness except that this children version contains Valerian in place of Lobelia. Valerian is a relaxing sedative, so I would not take this within a few hours of going out or some extraneous mental work such as important exams.

Calcium for children

Verified purchase

Calcium for children. This is the second time I've bought it. I give to my children 8 and 4 years old. My son has slow growing molars, after starting a course of calcium immediately begin to grow. It tastes neutral, no need to write anything down . The quality is satisfactory. The package is enough for a course of 2.5-3 months
