Less likely than carbonate to cause bloating or constipation.\n  \nFlexible dosing: 250mg per capsule lets you adjust based on dietary calcium intake and training load — take 1–2 capsules depending on needs.\n  \nDoesn't require stomach acid: Can be taken with or without food. Take 3+ hours apart from iron (calcium and iron compete for absorption).\n  \nNSF Certified for Sport®: Independently tested for banned substances and label accuracy. Vegan, gluten-free, dairy-free, GMO-free.\n","images":["https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Calcium-Bottle_2000x2000_05112025_fbf29399-d4b9-4f3d-b2e7-009452c713da.png?v=1780606058","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Calcium-USP.jpg?v=1780606057","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Calcium-HowtoUse.jpg?v=1780606057","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Calcium-SocialProof.jpg?v=1780606057","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Calcium-MomentousStandard.jpg?v=1780606057","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Calcium_Supp-Facts_2000x2000_03192025_FINAL.png?v=1780606057"],"price":16.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:54.810Z"},"share_url":"https://firestarter.network/l/lst_K33rnW_q","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
