Opening capsule, Half life and posologie

Hello guys,

I already posted about my regimen, but I still have some questions :

According to what I see on Google:
- Quercetin Half life is 11 to 12 hours / lifetime = 55 to 60 hours --> Once a day is enough
- Curcumin half life is 6 to 7 hours / lifetime = 30 to 35 hours --> Once a day is ok
- Resveratrol half life is 2 to 4 hours. So its lifetime is around 10 to 20 hours. It would be better to take it 2 times a day.

My question are :
- is it ok to take resveratrol once a day ?
- I have 500 mg caps of resveratrol, is it ok to open it, divided it and drink the powder with water ? (my 6 months stock would last 1 year)
- Is it ok to take curcumin once a day at 500 mg ?
- About quercetin, it should be ok to take 250 mg every day, even EoD would be enough, right ? What do you advise here ?

Thanks for your light.
