Hi Dan,
It’s just a matter of total accumulated heat. The first stage is slower to oxidize, so it requires oxygen at a slower rate. Thus it’s a good time to cut back on mixing without any concern at all of “starving” the reaction for oxygen. With the blenders I’ve used, the time it takes to complete the additional stages with constant mixing is not enough to worry about overheating the mixture. So it’s just simpler to mix constantly for the remaining time. The video is long, and I couldn’t include every detail that I wanted to. But since you brought it up, here’s another thing to know: If you are going to try making the DHAA concentration higher by more “additions” of AA, then the overall process is going to take more time, therefore more heat accumulates. So, instead of constant mixing, it may become necessary to be “more conscientious” during the later stages too, by using the same process of intermittent mixing.

When taken orally, 5 grams of DHAA results in peak blood plasma vitamin C levels twice as high as AA or liposomal C. DHAA for dietary use can be made by an economical, do-it-yourself method right at home. I have published a YouTube video that teaches you how to make it. This is a very long video (45 minutes) that discusses the science behind why DHAA is absorbed so much better, shows actual blood absorption data comparing various oral forms of vitamin C, and demonstrates in great detail the DIY method for making DHAA. People who are interested in achieving high blood levels of vitamin C will be very interested. I am going to post a link to this video here, but before I do, please be informed of the following disclosure and notice: My name is Doug Kitt, and I am a commercial vendor of vitamin C products. I have a commercial interest in the video. The name of my company is mentioned several times, and one of my products is briefly discussed. You will be asked for a donation at the end of the video. Furthermore, data is presented that some people consider critical of liposomal C. If any of these things is likely to offend you, please don’t click on the link! http://youtu.be/YHKBhz7OCB4
