Positive experiences
“I know people say you get enough vitamin C from diet but I feel and look better when I supplement it.”
“My immunologist increased my daily vitamin c intake to about 8 grams a day. I have never felt better.”
“Vitamin C and D have helped me a ton... now it's extremely rare I get sick.”
“But that pain gets significantly better when I take glycine, vitamin C and B6 together.”
“I contribute it to saving me several years ago, 'curing' severe depression, anxiety, low energy levels, even my gum health.”
“The vitamin C assists with excreting the Adderall so that I can get 8-9 hours of sleep (20:00 - 04:30).”
Negative and mixed experiences
“I've been trying to calm it down with Phopshatidylserine, Vit C, and Magnesium, assuming it's something to do with Cortisol or Adrenaline. But I can't seem to get it to go away.”
“I’ve been taking 500 mg of Vitamin C daily for 2 years and haven’t noticed any decrease in muscle building while working out 5 times a week with a solid diet.”
“I do take vitamin c and drink a glass of oj at about 6pm, so it soaks up the stimulants, helps me sleep and keeps tolerance low.”
“I took 2500mg of Vitamin C a day for a few days, and had the worst heart palpitations, sleep apneas, bone pains and bleeding gums I've ever experienced.”
