It's probably better to take it throughout the day. I tried to chug it once and I wound up being terrified whenever I stepped away from the toilet for more than 5 minutes lol. I tried taking the DCP Powder in one shot with my morning Amla Powder. Went fine.
Throughout my fast, I've been taking this multivitamin. Says its "for women", but it still has all the RDA amounts I need. I also take Amla Powder for a cholesterol experiment I've been doing while fasting.
This study demonstrated that Amla Powder and Simvastatin generated similar results in lowering cholesterol, and Amla Powder improved blood pressure in 75% of people, compared to 60% for Simvastatin.
This study demonstrated that Amla Powder FAR outperformed placebo too, as to be expected. Figured it couldn't hurt lol.
I also took Metamucil for the first few months of my fast because I saw the Fasting Fatman guy do it, but it kept putting me into the "don't trust a fart" territory lol.
It's a good idea to work up to the longer fasts. Some folks tolerate it better than others for some weird reason. Better safe than sorry. Best of luck to ya.
