No more osteoporosis!
This is pricey, but a great product! 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 Amazon. I had always ordered directly from the company, but for my last order or two, I ordered from Amazon 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!

Bone density improved
I honestly never review stuff but I just want to help others. I started feeling hip pain. I got scan I my bones were bad for my age. I have been taking this for a couple of years and my scan show slight improvement which is rare with bone density. I just did another last month is is on the normal side for my age.

Incredible Customer Service
I've been taking AlgaeCal since January due to osteoporosis in my spine. I recently contacted customer service to return a twin pack after my doctor asked me to stop taking Strontium because it can artificially improve DEXA scores. The customer service was incredible! They responded within 24 hours and after reviewing my purchase they refunded me and told me I didn't have to return the product. I will absolutely keep taking AlgaeCal Plus (without Strontium) and report back on my DEXA in January 2027, but 5 stars for incredible customer service!

Good Product but Not Really Plant Based
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.

Amazing Results Rebuilding Bone Density
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.

Seems to be a good quality product
So far I’ve implemented taking these into my schedule. Won’t know for months if they have helped.
