And those nutrients will work from the very first day you take them. But bones grow slowly. That's why people take strontium citrate 680 mg capsules because it's known as a bone stimulant.

All participants in studies with AlgaeCal saw increases in their bone density. Participants who took Strontium Boost alongside AlgaeCal supplements saw triple bone density increases. It's a pure natural supplement that in combination with a plant based calcium supplement can help in the healing of a bone fracture. Natural & Organic : Strontium citrate is found in natural soil. In fact, it's already in a lot of the vegetables you eat. And when combined with citrate you get strontium citrate It's a real bone boost! Bone Strength Supplement : Strontium Boost slows down the cells that eat-away at our old bone, and speeds-up the cells that build healthy new bone – resulting in stronger bones in less time.

Vegetarian Capsules: Our vegetarian capsules are non-GMO and free from dairy, soy, and gluten. We manufacture our supplements in a cGMP certified FDA inspected facility here in the USA. Review: The REAL Thing - Most 'cheap' strontium supplements that claim to be the citrate salt are actually strontium sulfide, a mined product that emits hydrogen sulfide gas (rotten eggs) when it contacts water. This product is the real thing. Strontium is a prescription drug in Europe. It does NOT cause jaw enlargement but can increase risk for heart attack in high risk patients. Consult a physician before taking. Strontium reduces fracture risk in osteoporosis. Review: Excellent product, Excellent company - Product does what it promised. ## Features - Bone Health Supplement : AlgaeCal has all the nutrients your bones need.

This dual action helps increase bone mass naturally, safely, and quickly. **Q: Is it supported by clinical research?** A: Strontium Boost is backed by three rigorously conducted human intervention studies showing that it increases bone density. In fact, it’s the ONLY strontium supplement clinically supported to increase bone density. **Q: Are there any reported side effects?** A: 7-year clinical study on Strontium Boost & AlgaeCal Plus found that bone density increases were reported “with no adverse side effects.” It’s a natural mineral that’s found in most root vegetables––so it’s a safe way to increase bone density. **Q: Does Strontium overestimate DEXA results?** A: Strontium is heavier than calcium, so it can inflate DEXA results by 8–11%—but that doesn’t mean the bone gains aren’t real. If your scan shows a 10% increase, even after adjusting for strontium’s weight, you’re still got a 9% gain in bone density. **Q: Can I take Strontium Boost without Calcium?** A: No, Strontium is heavier than calcium, and without enough calcium intake alongside it, strontium can start replacing calcium in your bones over time. That’s why Strontium Boost should always be taken with AlgaeCal Plus to ensure proper bone health. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The REAL Thing *by M***K on April 25, 2026* Most 'cheap' strontium supplements that claim to be the citrate salt are actually strontium sulfide, a mined product that emits hydrogen sulfide gas (rotten eggs) when it contacts water.
