May bago akong discovery, ito na ata sagot sa vein-abuse nating pinag-gagawa, it's called rutin or rutoside, it's a bioflavanoid, extracted from some fruits and plant stuff. Here's a summary of the benefits i've collated from webMD, livestrong, and wiki:
- it strengthens the structural integrity of the veins, apparently kailangan ko ito, dahil sa EOD ko
- helps the body utilize vitamin C and produce collagen <--- THIS! Need i say more about collagen?

- is an anti oxidant, gluta being another anti oxidant, they can work synergistically
- "Recent studies show rutin could help prevent blood clots, so could be used to treat patients at risk of heart attacks and strokes.[19]", ito din problem ko, my blood clots fast, kaya nawawala back flow ko minsan, tapos needle gets occluded na (failed session)
I tried to ask sa mercury for this rutin, pero wala pa daw, kasi isang pharma palang daw nag-launch nun, pero wala pang initial stocking. I also searched sa sulit kasi baka meron yung mga nag-iimport ng food supplements from US, pero wala ako mahanap. So me, being a med rep, hinanap ko sa area namin yung nagp-promote nung gamot, may samples na siya, pero limited lang, nanghingi ako, pero since di kami close, 3 tablets lang binigay niya sakin, tas bibigyan daw niya ako discount once available na for sale yung food supplement, it gonna be by the end of this month daw. The one they're marketing includes 500mg of vitamin C na, and is promoted for varicose veins, pero the active ingredient per se is good for overall vein health, plus the other benefits pa nga. I'm on my 2nd day of taking it, can't wait maging available siya, kasi pang hanggang bukas nalang maiinom ko

i don't like the flavor though, pineapple kasi na chewable tab.
