I would buy AlgaeCal again, but due to further research, I would not buy the Strontium boost again. I learned that even though this element may show up on a scan as developing better bone density, it tends to make the bones less flexible and more brittle.

I have taken this product since April. I had osteoporosis, and had been pressured to take Fosamax or Prolia for a few years. I researched other options, and decided to try this. I had my 2 year bone scan in early December, and there was significant improvement in my spine and hip bone density. My arm is still classified as osteoporosis, but my spine and hip are now classified as osteopenia. I am thrilled with the improved bone density after just 8 months. My doctor questioned the results, and called the tech to pull the images from 2 years ago for comparison. He told her the images were good and clear, and there was definite improvement in my bone density. I will be continuing my regimen of algaecalplus and strontium boost, along with the daily vitamins that are recommended.

I had osteoporosis, then my nutritionist suggested I take these supplements, that they work, and when I took another bone density test, I no longer had osteoporosis. My nutritionist was right; my doctor, and I, were thrilled.

I was diagnosed with osteoporosis of the spine and osteopenia of the hips in April 2012. My sister saw Algae Cal mentioned on Dr. Oz and told me to try it, since I did not want to go on a prescription drug until I tried reversing it with natural means. I began taking the calcium and the strontium, bought a rebounder for exercise even though I am a swimmer, and began eating free-range eggs, which are high in vitamin K2. A year later, my doctor wanted to put me on the prescription meds, but I convinced him to let me have another bone scan before making the decision. To my delight, the scan came back showing NO osteoporosis or osteopenia, so I am pleased. I may never know how much a part of the osteoporosis reversal the calcium and strontium made, but it was obviously a part of it, possibly significant. If you have had jaw surgeries as I have and want to try something without risk for jawbone loss that the RX osteoporosis drugs carry as side effects, try this product.

Seller did not list possible serious side effects.

Last week I had a DEXA test, after a year of being on AlgaeCal & Strontium Boost, and although I still have osteoporosis by WHO criteria (the BMD T-score was -2.9, as compared with -3.3 last year), the increase in bone density was impressive enough so that my dr. says, "Stay with it!" Last year, after six months of using your Combo, the T-score had gone down only a tenth of a point or so, but then he noticed that the increased bone density was in a part of the hip where most fractures occur. Thanks, Algae-Cal!!
