Animal Essentials Sea-Cal Powder is a natural, bioavailable calcium source made entirely from calcified red seaweed (Lithothamnium sp.)—sustainably harvested from the pure, mineral-rich seabeds off Iceland’s coast. Unlike synthetic calcium carbonate, Sea-Cal offers a gentle, food-based mineral matrix that’s easy to absorb and doesn’t strain your dog’s kidneys or GI tract.\n✓ Whole food source of calcium and 70+ trace minerals✓ Supports healthy bones, joints, teeth, and growth✓ Highly bioavailable—easy on digestion and kidneys✓ Sustainably harvested from pristine Atlantic waters✓ Ideal for balancing homemade, raw, or cooked diets✓ Free from synthetic additives, heavy metals, and fillers\nWhy It WorksCalcium is essential for strong bones, proper muscle contraction, nerve signaling, and even heart rhythm—but the form matters. Many commercial calcium supplements use mined calcium carbonate, which can be poorly absorbed and lead to mineral imbalances. Sea-Cal is made from Lithothamnium calcareum, a red algae that naturally bioaccumulates calcium, magnesium, and dozens of trace minerals in a highly bioavailable form. Because it’s plant-derived, Sea-Cal is more compatible with the body, less irritating to the gut, and better utilized at the cellular level.\nWhat’s Inside—and How It Helps→ Dehydrated Seaweed Meal (Lithothamnium sp.) – A natural source of calcium, magnesium, boron, silica, and 70+ trace minerals that support skeletal health, mineral balance, and enzymatic function\nPerfect For:✓ Dogs on fresh, home-prepared, or raw diets needing added calcium✓ Growing puppies or lactating females with increased calcium needs✓ Senior dogs needing bone and joint maintenance✓ Pets with sensitivities to synthetic calcium or minerals✓ Pet parents looking for a clean, food-based mi","images":["https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Copy_of_Copy_of_Copy_of_Untitled_Design.zip_-_46.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Untitled_Design.zip_-_310.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Untitled_Design.zip_-_313.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Untitled_Design.zip_-_314.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Untitled_Design.zip_-_311.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Untitled_Design.zip_-_312.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Untitled_Design.zip_-_315.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Untitled_Design.zip_-_309.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Untitled_design_-_46.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Untitled_Design.zip_-_317.png?v=1762647355","https://cdn.shopify.com/s/files/1/0702/6733/9061/files/Copy_of_Untitled_Design.zip_-_316.png?v=1762647355"],"price":40.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:37.371Z"},"share_url":"https://firestarter.network/l/lst_vAs_Lopz","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
