It doesn't surprise me to see that vitamin C looks so dynamic.
In my anecdotal experience with it, I haven't been sick with even just a common cold for many years now since I learned to drink a few swigs of orange juice (with lots of pulp) every couple of days throughout the week. Even friends who were highly skeptical have come around on this after many years. It's undeniable since I started my OJ regimen I just don't get fricken sick anymore despite being around plenty of sick, sneezy people in stores, sick loved ones and friends, sick kids, filthy thrift stores with grubby stuff I get my hands all over, heavy flu seasons and cold ass winters in Colorado.
I'm not even using expensive, fresh squeezed OJ, it's the "crap from the vat" that Tropicana and Simply Orange sells as "not from concentrate" and reintroduces essence of orange flavor (from the actual orange) later to make up for the otherwise poor taste induced from the shitty, heated vat storage. It's processed, but at least the processing doesn't involve anything but the natural orange itself, heat and pasteurization -- so I'm cool with it. The flavor packets they add is all processed orange parts. No artificial colors, chemical flavorings or preservatives. Fresh squeezed is an expensive hassle and I'm not getting sick with my current OJ, period.
At least with my particular physiological setup, vitamin C dispersed into my body through this silly OJ method has removed cold and flu from my life. It doesn't exist for me whether I have lack of sleep, exercise or both.
I've also noted that it's perhaps altered my pH levels or something. If I get lazy and skip OJ for a while, I notice that once I get back on the OJ wagon it tastes far more acidic and feels more acidic in my belly. But, as I get back into the regimen of swigging it every couple of days again consistently, it slowly becomes less acidic tasting and I begin to throughly enjoy it again with a refreshing taste I crave and without any acidic feelings in my stomach, mouth, throat, etc.
I know there's a lot of natural sugar in the OJ I use, but I literally only take a small squig or two every couple of days. One 59 oz container lasts me about a week to a week and a half.
I'm a pretty firm believer that the best way to properly absorb certain nutrients and vitamins is through food when it's practical and affordable.
For example, in my opinion foods deliver nutrients into my body as catalystic containers (as I ridiculously call them). I can eat straight up potassium supplements all day long and piss it out, but I eat a banana and I've got myself an extremely complex, badass, potassium delivery system that's evolved to break down throughout my digestive system in ways that pills cannot compete with.

This applies to many things (including fish) and this ties into the need for an enteric coating on the fish oil I take. Fish oil that's distilled to remove impurities is the only supplement I take since it's more practical than cooking stinky fish every night and dealing with the elevated dioxin and mercury that comes along with a fish diet nowadays.
I don't pretend to know how exactly the OJ (with lots of pulp) properly implements the vitamin C, etc. within my body to make me impervious to cold and flu all these years, but I do know I haven't been sick at all since I started.
Thank you, vitamin C from OJ.
• I am probably just a freak of nature, this weirdness may not work for anyone else. I may be slowly dying from this regimen. But, if you've tried it in a similar way as I have and you don't get sick or illness becomes very rare, please let me know. I want to know if I'm just a weird anomaly. Or, if you try it and get different, shitty results, please let me know so I can tell you you're doing it wrong.
• Research shows that for most people, vitamin C supplements or vitamin C-rich foods do not reduce the risk of getting the common cold.
• However, people who take vitamin C supplements regularly might have slightly shorter colds or somewhat milder symptoms.
• Taking a vitamin C supplement after a cold starts does not appear to be helpful.
• I am not opposed whatsoever to flu vaccines. I just don't need them and, yes, I've been exposed to flu many times over the years since I started my OJ thing including being in a hospital with a loved one for extended periods of time during peak flu seasons.
• If you do decide to try this, contact your doctor first and tell them a nutjob on the Internet sent you.
As far as enteric coasted fish oil goes. Don't listen to me, listen to the prestigious Mayo clinic and as with anything above, seriously see a doctor before doing anything I do.
There are specific fish oil supplies you can purchase that do not contribute in any significant way to the collapse of fisheries in the oceans. Research it. Also, I never take fish oil that isn't enteric coated. If a label doesn't mention any enteric coating, I find that the fish oil is (almost) worthless even if it's the super expensive, "fancy" kinds versus cheap, Walmart enteric coated capsules.
I've seen where enteric coated fish oil can cause people painful digestion problems if they are prone to problems or have previous gastrointestinal illnesses. If you have those issues, there are other ways besides enteric fish oil capsules to get the benefits, but you'll have to research them.
Although not having to deal with fish burps is nice, the reason I only use enteric coated fish oil capsules is so they'll be properly absorbed in the small intestines after protecting long-chain fatty acids from hydrolysis in gastric acidity in the stomach, etc.
I've found that enteric coated fish oil in moderation helps me in all kinds of ways (limits headaches and grogginess if I lack sleep, vastly better memory, mood enhancer despite my ornery nature, better sleep, better weight control, no heart palps with lack of sleep, I seem to be aging slower in some ways, etc.) after about a decade of testing. Too good to be true? Probably, I guess. Just my genetics, maybe with placebo effect in tow perhaps, but I've seen major differences while experimenting (I'd stop taking it for extended periods to see what happens and journaled it).
Beware that fish oil supplements can thin your blood to some extent. But, in my own case I've sliced my arms and legs open ritually while mountain biking here (I'll be releasing Go-Pro style videos to heavy soundtracks after this summer) and even with deep, vicious cuts I wasn't getting unusual bleeding, but your mileage may certainly vary.
Finally, for all I know all of this is just an extremely effective placebo effect so don't get your hopes up... or do get your hopes up and perhaps join me in my delusional, placebo fish oil bliss.
