Would just like to give some knowledge here which can be found from simple googling from many technical, medical, and research sites:
Vitamin C is basically only in the bloodstream for 30min as it shows here as well as so many other places in clinical human trials across the web:Absorption, transport, and disposal
Ascorbic acid is absorbed in the body by both active transport and simple diffusion. Sodium-Dependent Active Transport—Sodium-Ascorbate Co-Transporters (SVCTs) and Hexose transporters (GLUTs)—are the two transporters required for absorption. SVCT1 and SVCT2 import the reduced form of ascorbate across plasma membrane.[31] GLUT1 and GLUT3 are the two glucose transporters, and transfer only dehydroascorbic acid form of Vitamin C.[32] Although dehydroascorbic acid is absorbed in higher rate than ascorbate, the amount of dehydroascorbic acid found in plasma and tissues under normal conditions is low, as cells rapidly reduce dehydroascorbic acid to ascorbate.[33][34] Thus, SVCTs appear to be the predominant system for vitamin C transport in the body.
SVCT2 is involved in vitamin C transport in almost every tissue,[31] the notable exception being red blood cells, which lose SVCT proteins during maturation.[35] "SVCT2 knockout" animals genetically engineered to lack this functional gene, die shortly after birth,[36] suggesting that SVCT2-mediated vitamin C transport is necessary for life.
With regular intake the absorption rate varies between 70 to 95%. However, the degree of absorption decreases as intake increases. At high intake (1.25g), fractional human absorption of ascorbic acid may be as low as 33%; at low intake (<200 mg) the absorption rate can reach up to 98%.[37] Ascorbate concentrations over renal re-absorption threshold pass freely into the urine and are excreted. At high dietary doses (corresponding to several hundred mg/day in humans) ascorbate is accumulated in the body until the plasma levels reach the renal resorption threshold, which is about 1.5 mg/dL in men and 1.3 mg/dL in women. Concentrations in the plasma larger than this value (thought to represent body saturation) are rapidly excreted in the urine with a half-life of about 30 minutes. Concentrations less than this threshold amount are actively retained by the kidneys, and the excretion half-life for the remainder of the vitamin C store in the body thus increases greatly, with the half-life lengthening as the body stores are depleted. This half-life rises until it is as long as 83 days by the onset of the first symptoms of scurvy.[38]
Although the body's maximal store of vitamin C is largely determined by the renal threshold for blood, there are many tissues that maintain vitamin C concentrations far higher than in blood. Biological tissues that accumulate over 100 times the level in blood plasma of vitamin C are the adrenal glands, pituitary, thymus, corpus luteum, and retina.[39] Those with 10 to 50 times the concentration present in blood plasma include the brain, spleen, lung, testicle, lymph nodes, liver, thyroid, small intestinal mucosa, leukocytes, pancreas, kidney and salivary glands.
Ascorbic acid can be oxidized (broken down) in the human body by the enzyme L-ascorbate oxidase. Ascorbate that is not directly excreted in the urine as a result of body saturation or destroyed in other body metabolism is oxidized by this enzyme and removed.
Also Antioxidants can stay in the blood stream for up to 48hrs. However the potential to harm the MMS only lowers by a minor degree.
Point in fact: Vitamin C inactivates the MMS so stay away for it least 30 min, however antioxidants can only lower the power of MMS however especially on an empty stomach MMS digests in roughly 15minutes in the bloodstream and attacks generally up to the max of 1.5 hrs. However most of it's usefulness is used up within 45minutes. Hence my point you could say some food has a certain # of Anti-Oxidants in it however like Jim Humble has stated Don't worry about Anti-Oxidants in food only Vitamin C, however I agree with lowering the amount or purity of the Antioxidant foods while taking MMS doses. However taking so many doses per day lowering 1or 2 doses a day for the sole purpose of Accelerating your Immune System should be credited as crucial especially to the sick.
Immune system has to come first, without it we cant get better no matter what we take.
