Bluebonnet's Chelated Calcium Magnesium prioritizes quality and absorption with its selection of bisglycinate chelate forms for both calcium and magnesium. Calcium bisglycinate chelate is recognized for its excellent bioavailability and reduced gastrointestinal upset, making it a superior choice for calcium delivery. Similarly, magnesium bisglycinate chelate is a premium form, highly absorbable and particularly noted for its calming effects on the nervous system, supporting stress relief and sleep without the laxative effect common with other forms. The product offers a balanced calcium to magnesium ratio of approximately 1.25:1 (500mg Ca to 400mg Mg). Despite these outstanding mineral forms, a major drawback for a calcium product aiming for 'Bone Health' is the complete omission of Vitamin D. Without Vitamin D, the body's ability to absorb and effectively integrate calcium into bone tissue is severely compromised, meaning that much of the high-quality calcium provided may not be optimally utilized for its primary purpose. The higher price per serving ($0.73) reflects the premium chelated forms, but the lack of Vitamin D requires additional supplementation.
