This is not good advice, imho. He is defining vitamin C as two different forms of vitamin C, DHAA, and AA, as if they both are equally beneficial to the body.
Nothing could be further from the truth.
DHA A (normally referred to as DHA, even though the term DHA is already widely used referring to Omega3 FA) is oxidized vitamin C and there is quite a bit of data that suggests that more than your normal intake of DHA might *not* be a good thing.
AA, which is 99% of what you are using when you buy a bottle of regular vitamin C ... this form donates a bioavailable electron at the cellular level and provides an alternate pathway for aerobic ADP -> ATP synthesis (see http://crystal.res.ku.edu/taksnotes/Bio ... chp_17.pdf
, pages 9-11), which is the main reason why vitamin C gives you energy. It is also the reason it doesn't provide energy to cancer cells (which don't utilize the aerobic process). In fact for some people (self included) megadosing at night will make them sleepless. This conversion is very possibly why vitamin C provides protection to normal cells from oxidative stress exhibited by the mediation of H2O2 at the cellular level which is responsible for cancer cell death by Vitamin C (according to Dr. Mark Levine and fan club).
The utilization of vitamin C for aerobic ATP synthesis is perhaps it's most valuable asset, besides building connective tissue (which is a secondary function when megadosing). It is the same mechanism (reducing O2) whereby vitamin C is a powerful antioxidant. Your body only contains less than 0.1 mol of ATP (less than 0.05% of one's body weight) so it has to be constantly synthesized and vitamin C helps do that. When someone is fighting an illness this form of energy is vitally important. It is the presence of this bioavailable electron that gives it it's antioxidant power ... in other words if you're consuming DHA then you're most likely not getting much if any antioxidant effect from it. At best one might call it a pro-oxidant in cancer cells and an inactive antioxidant (and I think that might be giving it too much credit , and involves a number of assumptions I'm a little uncomfortable with).
If your body needs DHA for any reason, it will create it from the AA already in your system (yes, within 30 minutes an entire RDA amount of AA orally consumed will be converted to DHA). All other DHA not utilized in that way is essentially wasted and are maybe even bad for you (at least observations seem to validate this ... see 3 points below).
In the video he claims that DHA once absorbed into the cell is converted to AA ... now this is true, but as I understand it this takes energy ... just as going from AA to DHA imparts energy to synthesize ATP ... the molecule responsible for energizing all cellular activity. So, again, consuming DHA is kind of like breathing in CO2, imnsho. Not doing you a whole lot of good filling your cells with spent fuel.
The bottom line though, all theories aside (and yes, I do think much of this science is still in the theoretical stages) in practice that DHA supplementation has never demonstrated statistical significant benefit in either the test-tube or the human body model, in any way
. Never ever. In fact the general consensus among many of the experts in the field have observed the opposite. Consider the following:
1) Dr. Cathcart, who individually has performed more IVC (intravenous vitamin C) infusions than anyone else ... reportedly over 25,000, claimed that from his observations the benefit from IVC was sharply reduced the more yellow his solution was from oxidation (DHA). In other words, "less DHA" is better treatment. He recommended having as colorless of a solution as possible and gave advice how to keep it colorless (don't completely dissolve it until you use it ... vitamin C will stay reduced much long when it is sitting in the bottom of the beaker being highly concentrated).
2) In 2008 a misrepresented study by the Sloan Kettering Institute run by a Dr. Mark Heaney he claimed from the results that vitamin C does not only kill cancer but may even promote tumor growth. On closer investigation it was discovered that he used blood plasma levels that were not only way too low (they were similar to what one would get from oral vitamin C ... similar to the infamous Mayo clinic studies in the early 80's) ... he also used purely oxidized vitamin C ... or "orange crap" as I like to call it. This orange crap is the DHA acid that this video you refer to discusses.
3) Excessive DHA has been suggested as a potential factor in diabetes (http://www.ncbi.nlm.nih.gov/pubmed/14829572
), and cataracts (http://www.ncbi.nlm.nih.gov/pmc/article ... Patterson2
There is a reason 90% of the vitamin C in fruit is AA: because bioflavonoids keep it that way. I believe the concentration is much higher when fruit is on the vine. The concentration of DHA only increases as fruit begins to rot. While there are somethings that are more healthy when they ferment, it is usually a biological process causing the fermentation ... the rotting of fruit is generally a non-biological process of oxidation, which is pretty much always not such a good thing as far as enhancing nutrition.
There is of course the Ester-C crowd that claims that their vitamin C is superior because it has something like what ... 30% DHA in it? After some 40+ years of them claiming this there still has yet to be a single peer reviewed study that validates any claim that their vitamin C provides any more benefit than regular vitamin C. The data just isn't there. It does however have the remarkable effect of making it a little easier to walk though, as it will likely drain your pocket from any loose change that may have otherwise been weighing you down.
It may be that a small portion of DHA vitamin C might be beneficial, but as I said ... your body will convert all your AA into DHA in 30 minutes (in normal doses ... megadosing can lengthen this), or in other words by taking pure AA you're getting all the DHA relatively quickly that you need and it will make it into your cells anyway. Hopefully though you're taking enough other nutrients to regenerate AA from the intracellular DHA, and most of that DHA will be removed by the kidneys very efficiently (again, hopefully).
In the end the proof is in the pudding, and those who've done the observations say: DHA doesn't seem to help anything.
I also would like some information how he did his calculations. You can do a psuedo test for vitamin C absorption by doing a simple finger stick blood glucose test before and after. I suspect this is the method he is using. The reason this test works is because vitamin C also shows up on this test. It is not very accurate, but accurate enough to safely say his results are significant and remarkable. Again, I don't think it means anything other than his body is suddenly accumulating a whole lot of something that won't do him any good. IMHO the AA:DHA ratio is critical and this test does not provide that ratio information, but I'm certain practically none of that DHA is being converted to AA in his cells, and in fact may be doing him harm.
I do think however his methods are to be applauded, and I'm impressed with it compared to all the other psuedo-scientific revelations you normally get on youtube. These blood glucose readings should provide additional and very important insight into Vitamin C pharmacokinetics. He is to be commended on his methods, although I do not agree with rushing to any treatment recommendation based on his theory.
