Natural Calcium Supplements vs. Synthetic Calcium Supplements
-
PureBone Strength:
🟢 High bioavailability: Absorbed by the body at approximately 70–80% due to its natural form and the presence of cofactors like magnesium and vitamin D3.
🟢 Safety: Gentle on the body with a low risk of overdose. Suitable for long-term use.
🟢 Comprehensive action: Contains not only calcium but also magnesium, vitamin D3, and trace marine minerals — supporting bones, muscles, and overall well-being.
🟢 Vegan and hypoallergenic: Free from animal-derived ingredients, suitable for most diets.
🟢 Eco-friendly: Sourced from renewable marine resources without the use of harsh chemicals.
-
Synthetic Calcium Supplements:
🔴 Low bioavailability: Absorbed only at 20–40%, especially poorly in cases of low stomach acidity (common in older adults).
🔴 Risk of side effects: May cause constipation, bloating, or nausea. With prolonged use, there is a risk of vascular calcification and kidney stone formation.
🔴 Limited effectiveness: Often includes only calcium and synthetic vitamin D, lacking additional supporting minerals and trace elements.
🔴 Not always vegan-friendly: Some forms contain gelatin or are derived from bone meal.
🔴 Environmental impact: Production involves chemical waste and has a significant carbon footprint.
