The main concern with any Vitamin C product occurs when megadoses are consumed orally. The powerful antioxidant activity can neutralise the active ingredients of some drugs including some of those used in chemotherapy, blood thinning agents and psychoactive drugs.
Some antibiotics work well with Vitamin C while others are less effective in it's presence. Asprin and NSAID's drug types are also incompatable with vitamin C as they are inclined to cancel each other out. This is because Vitamin C is a toxin neutraliser.
If you have a medical issue and/or are taking prescription drugs check with your health professional. If you can, preferably find one who has researched the topic. Some medical profesionals have a deeply rooted anti-vitamin stance because of the many false claims made on the internet regarding curing cancer and the emotional damage caused by giving false expectations to vulnerable patients.
On the positive side new research is constantly proving how important vitamin C is for a myriad of difficult to treat illnesses, infections and some cancers, particularly regarding quality of life in palliative cases.
Drugs.com list 137 drugs that interact with Vitamin C, only eight have moderate interactions, a further 129 are considered to have minor interactions. Unlike most drugs vitamin C is relatively compatable with the vast majority of treatments and is completely harmless to almost everyone.
However, if you are considering megadosing any type of vitamin C have a blood test to check for G6PD deficiency. This rare condition reduces vitamin C tolerance and you can have a serious reaction to a high dose.
Diarrhea also often occurs at high doses of vitamin C.
If you take the DHAA/Vitamin C serum orally remember that the DHAA component is seven times more potent/absorbable than normal Vitamin C. Just 5 grams of pure Dehydroascorbic acid will raise blood vitamin C levels around the same as 36 grams of Lipospheric Vitamin C.
Most of the cases reported on this website used doses of between 500mg to 1000mg per day topically. Little DHAA is needed as it is very potent form of vitamin C due to it's high absorbtion rates whether taken orally or topically.
Experimenting with high dose oral DHAA (more than 3 grams) is new and largely untested. As demonstrated by Doug Kitt's research DHAA is a very potent form of Vitamin C when taken orally and only IV infusuion can raise blood levels further.
I have frequently taken up to 4 grams per day in staggered doses or single doses, personally I would only go beyond that with extreme caution. One teaspoon of our DHAA Ascorbic Acid Serum contains around 750mg of total vitamin C. The DHAA content is slightly less than half of the total vitamin C.
Ingredients are: Organic Vegetable Glycerine and Ascorbic Acid. Only pure oxygen is used in the manufacturing process to convert some of the ascorbic acid to dehydoascorbic acid.
Cystine supplements may also be required to ensure the body has sufficient to maintain glutathion levels if taking high dose DHAA.
Bowel tolerance levels may not be reached with DHAA so the titrating to bowel tolerance test should not be used for DHAA as you could overload your glutathione producing capability.
Without question DHAA is the most potent form of Vitamin C for raising blood levels of natural Ascorbic Acid. Always remember much less is needed to do the job!
The Asorbic Acid and Dehydroascorbic Acid we use in our products are the two most natural forms of vitamin C.
