I went from osteopenia to osteoporosis, all while progressing through all the prescription meds. I finally did my own research and came across this product! I have been taking it for several years and my last bone density scan was nearly normal! No more osteoporosis! My only complaint is with ordering from desertcart. I had always ordered directly from the company, but for my last order or two, I ordered from desertcart and they don't have the correct ratios for the 3 month bone builder pack. I should not be left with one bottle of the strontium boost and 3 bottles of the algaecal plus! I guess I will go back to ordering directly from the company because this is a very important supplement for my bone health! Review: AlgaeCal & Strontium Plus cured my osteopenia. My bones are very healthy now. ## Features - CLINICALLY-SUPPORTED FORMULATION: The Bone Builder Pack has both AlgaeCal Plus and Strontium Boost. A full serving of the AlgaeCal Plus calcium formula contains 720mg of plant-based calcium and 350mg of magnesium. It's also the ONLY supplement duo by three human clinical studies. - TRIPLE BONE BUILDING: Taking Strontium Boost together with AlgaeCal Plus has been shown to 3x bone density increases - ESSENTIAL VITAMINS AND MINERALS: We supercharge our supplement by adding 1600IUs of vitamin D3, 100mcg of vitamin K2 MK7, 50mg of vitamin C, and 3mg of Boron. These ingredients are essential for good bone health and play a critical role in calcium absorption. - PLANT-BASED: Since we derive our calcium from a whole food source (raw marine algae), it naturally contains 13+ trace minerals which further boost bone-building. The raw marine algae we use is simply sun-dried and then ground up into a fine powder for maximum effectiveness. - MANUFACTURED IN THE USA: We believe in only using top quality ingredients, so we manufacture right here in the USA. Capsules are veggie-based. Dairy Free, Soy Free, Gluten Free and Non-GMO. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07M861K45 | | ASIN | B07M861K45 | | Age Range Description | Adult | | Best Sellers Rank | #100,925 in Health ( See Top 100 in Health ) #2,005 in Mineral Supplements | | Brand Name | ALGAECAL | | Customer Reviews | 4.6 4.6 out of 5 stars (333) | | Customer reviews | 4.6 4.6 out of 5 stars (333) | | Dosage Form | Powder | | Flavor | Unflavored | | Item Dimensions | 22.9 x 19.1 x 6.4 centimeters | | Item Weight | 0.81 Kilograms | | Item model number | Calcium Supplement | | Manufacturer | AlgaeCal | | Manufacturer | AlgaeCal | | Manufacturer Part Number | B07M861K45 | | Material Features | Dairy Free, GMO Free, Gluten Free, Plant Based, Soy Free | | Material Type Free | Dairy Free, GMO Free, Gluten Free, Soy Free | | Model Number | Calcium Supplement | | Number of Items | 3 | | Primary Supplement Type | Magnesium | | Product Dimensions | 22.86 x 19.05 x 6.35 cm; 812 g | | Special Ingredients | Vitamin K2 MK7, Magnesium, Strontium, Trace Minerals, Boron | ## Product Details - **Age range (description):** Adult - **Brand:** ALGAECAL - **Dosage form:** Powder - **Flavour:** Unflavored - **Item dimensions L x W x H:** 22.9 x 19.1 x 6.4 centimeters - **Item weight:** 0.81 Kilograms - **Material features:** Dairy Free, GMO Free, Gluten Free, Plant Based, Soy Free - **Number of Items:** 3 - **Primary supplement type:** Magnesium - **Special ingredients:** Vitamin K2 MK7, Magnesium, Strontium, Trace Minerals, Boron ## Images ![Bone Builder Pack – Plant-Based Calcium Supplement with Magnesium, Boron, Vitamin K2 + D3 | Includes Strontium Boost | Naturally Increase Bone Density (3 Month Supply) - Image 1](https://m.media-amazon.com/images/I/61kW50wHbAL.jpg) ## Questions & Answers **Q: I heard Strontium is unsafe.

My bones are very healthy now. ### ⭐⭐⭐⭐⭐ Review *by B***C on 20 January 2026* Algaecal and Strintium Boost were recommended to me by my OBGYN. I was diagnosed with osteoporosis stage 3. I did not want to use the prescription bone density builders because of the know side effects. So, at my OBGY's recommendation, I religiously took Algaecal and Strontium Boost for just about a year. I had another bone density scan done at 1 year. I have moved from osteoporosis stage 3 to osteopenia. My OBGYN says that that kind of progress in rebuidling bone density is virtually unheard of without significant medical intervention. I am so grateful. No side effects and significant results--likely far better than the prescription remedies. ## Frequently Bought Together - ALGAECAL - Bone Builder Pack for Bone Density, Clinically Supported Plant Based Calcium Supplements & Strontium, Vitamins K2, D3, Magnesium & 16 Minerals, 3-Month Supply, Made in USA - ALGAECAL 4-in-1 Vitamin D3 K2 Complete - ADK Vitamin Supplement, Enhanced Immune Support & Bone Health with D3 K2, A, & E - Whole Body Wellness & Bone Strength, 60 Easy-Swallow Softgels, Made in USA - ALGAECAL Collagen: 4 Clinically-Supported Peptides VERISOL®, FORTIGEL®, UC-II®, FORTIBONE®, Anti-Aging Hydrolyzed Collagen Powder, 30 Servings, Made in USA --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/438092498-bone-builder-pack-plant-based-calcium-supplement-with-magnesium-boron](https://www.desertcart.pl/products/438092498-bone-builder-pack-plant-based-calcium-supplement-with-magnesium-boron) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
