Be careful with that much spinach - it has oxalates which cause kidney stones! I go with arugula. Dr. Jorge Fleches (on You Tube) was the first doctor I knew of taking 120 mg of boron daily. Since then I have met a lot of people with different diseases (not just osteoporosis) that take 120 mg per day. I am sicking with 24 mg per day and I've stopped fracturing. I did stop taking calcium as I was having heart problems. I was going into v-tach. Calcium is powerful stuff and you should never take it without taking vitamin K2 (mk7, mk7). I take InnovixLabs brand of vitamin K2. I'm sure there are other good ones. One thing the nutritionists say is don't take calcium that has magnesium. Vitamin D3, and K2 all mixed in - take each one separate. They recommend oyster shell calcium - nothing fancy. They also say to keep track of how much you are getting in your food and subtract that out from any you are taking in pill form. Also, you need vitamin K and vitamin K2 for different things - The K2 should be (mk4, mk7, or both) as this is the form that humans absorb. If you don't like the taste of natto, you should get it from a capsule (they are tiny). I pay $20 for a three-month supply. I'm going to call today to make an appointment for my DEXA scan - my old order timed out so had to wait till it was called in again. But I have stopped fracturing. I will keep you posted. I got my second vaccination for Covid yesterday so I want to go in a week or two at the earliest. Dr. Fauci says we are probably going to have another surge in 2-3 weeks.
