I was diagnosed with osteoporosis in my 30s, apparently due to lack of sunlight/vitamin D.
After a lot of research, I discovered a group of scientists had made a study on calcium found in nopal cactus powder.
I'm going to add a link to the article, I hope it's not a problem. They don't sell anything and neither do I.
I've been taking about 15 grams of nopal cactus powder every day with no side-effects.
I bought dry nopal powder, it had no other ingredients, if you can't find it, you might get some results with the capsule form of the powdered nopal.
So, I poured one spoonful of the powder in 3 cups of water, added salt and powdered onion, and let it boil for a few minutes. I would drink about half of the "soup" after meals, I didn't drink all of it on a single day because I felt it was too much.
You can of course adjust the amount of powder/water you consume.
Unfortunately during the pandemic, I no longer went to see if my bone density had improved. If I ever find out again, I'll let you all know.
