@joglow,
my personal bias is that these gentlemen selling minerals and vitamins for osteoporosis are making a lot of money from a vulnerable population. I listen to the videos, but prefer to find the supplemental ingredients they recommend with more moderate pricing.
I find Ellis, McCormick and especially Lucas intelligent and compelling. https://www.youtube.com/watch
I take vitamin k2, d3, low dose calcium, magnesium orotate. Adequate protein intake is important for bones. You might consider strontium citrate.
But I also take Forteo. It's possible that you would qualify for $80 pens with RXAdvocates if you decided to take my favorite drug, Forteo https://therxadvocates.com/
