px17&yijiheon: naks ano itong high grade gluta eklavu? so may class b at c naba ito?hihi
but true sis,I saw claims like that rin..way waaaay back. Although there will never be people who would test the content, I would highly believe it all boils down to gluta purity.
Does anyone remember may issue noon na certain brands claim 1g gluta in the pill, 1.5g .. but upon further testing eh..200mg lang pala,at isang component lang ng glutathione..bale, glutathione is a tripeptide, meaning 3 kinds of proteins yun..those 3 proteins need to work together to be effective..and of course they need to be in the right part of the body (e.g NOT THE TUMMY)
its like, in order to make a house(glutathione).you need wood, nails and a hammer. (l cysteine, glutamic and glutacin) say gluta is like package deal you can buy.
Some packages can claim that they will give you a huge house(high glutathione content), pero wala palang nails (so its lacking the basic amino acids that make up gluta in the first place) or the house ends up small (misleading information stated above) or your house actually ends up as rubble (fillers)
Some will claim you get a nice beautiful house and they have the evidence to prove it. But on your way to the beautiful house, your house gets hit by a landslide (e.g oral route and claims of no effectivity from oral supplementation of glutathione)
more info available on this in this study:

It is common info that only through consistently elevated levels of glutathione in the blood for a long period in time will it prohibit melanin synthesis. It is observed in the study that in the short term,there is no benefit or even elevated levels of glutathione in the blood. So how then, does skin whitening occur?
http://www.altmd.com/Articles/Glutathione--Encyclopedia-of-Alternative-MedicineSee the preparations portion. You're often better off with vitamin C.

Which may explain why Im not whitening with Tat kase Im not drinking Vitamin C as often as I should be, no matter how overdosed I am on Tathione..
But fret not, here is another study!

So go lang ng go pa rin! Palagi nalang ako nag.ramble dito. hehe
Can someone also be so kind enough to try the lande (lol) glutathione? much thanks.
If you ask me, how long did it take me to notice the difference sa oral gluta? Can I say like, never? LOL because no one ever reacts if Im on oral glutathione

sa inject lang. boo hoo. May one time tita said parang pinkish cheeks ako sa ph.. pero I personally dont notice anything too drastic. zzz
