Review: 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.
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.

### ⭐⭐⭐⭐ Review
*by F***Y on 22 February 2025*

While the AlgaeCal calcium supplement did help my bone density tremendously after a fall resulted in a hip bone fracture, I am very disappointed that this product is advertised as plant based. The vitamin d3 is sourced from Cholecalciferol, a sheep wool lanolin derivative. The practice of extracting Cholecalciferol in large scale sheep shearing can be extremely rough and cruel to the sheep. I feel that saying this is a plant based product is deceptive advertising. I recently purchased the AlgaeCal Plus Bone Builder Pack based on this being plant based but on further research I discovered it really isn’t. I also ordered this because I took the AlgaeCal calcium supplement over the several months following hip surgery. The last hip x-rays proved that my bone density had become very good. I want to be sure my bones are all as strong as they can be and will finish the Bone Builder Pack I have purchased, but as someone who loves and has compassion for animals I am aghast at what I have read about lanolin processing. I hope AlgaeCal changes their sourcing of d3 and makes this product truly plant based in the future. There are plant based alternatives for vitamin d available.
