FWIW, while we do a daily natto/serra, we also go high-dose 2X a week, spread out evenly. Even with all the anti-shedding protections, I can often feel that something is off 24 to 48 hrs after spending extended time in a huge crowd. Some amount of spike still managed to sneak through, enough to cause microclots.

I was just thinking that a course of high-dose N/S would likely have helped this lady with the bone-rotting condition.. there's a number of areas in our bodies where critical bone structures only receive the bare minimum blood flow. Hips are notorious for that.
