Vitamin C Dosage: How Much Vitamin C Do You Need?

Did you know that humans are one of the few mammalian species on Earth whose bodies cannot produce Vitamin C? Lucky for us, and not the primates and guinea pigs who also do not make Vitamin C, we know we need to get this essential antioxidant through diet. What we often don’t know is how much we need each day. And that’s because there are just so many recommendations out there.

According to U.S. government guidelines, adult women should take 75 mg of Vitamin C each day, and adult men should take 90 mg. To complicate the matter, many experts recommend a Vitamin C dosage of between 200 mg and 1,000 mg daily, or even more, to achieve maximum benefits.

The goal of daily Vitamin C intake is to attain optimal saturation levels in the blood and tissues. However, measuring those levels can be complicated. Vitamin C is water soluble, which means that excess portions are flushed out in your urine. Different organs and bodily fluids have different Vitamin C retention capabilities. The adrenals, brain, eyeballs and prostate can retain high levels of Vitamin C, while blood plasma retains less. The problem is that medical professionals often use blood plasma to test the body’s overall Vitamin C levels, which can produce misleading results and differing opinions on daily intake requirements.

So how much vitamin c should you take each day? Authorities have varying opinions, but the majority seems to favor Vitamin C dosage in the range of 200mg to 500mg per day. They also suggest breaking up daily vitamin consumption into two or three doses. This allows your body to receive Vitamin C in waves, counteracting vitamin loss through the urine. There is also some consensus that older adults, smokers and lactating mothers should consume more vitamin C.

Vitamin C is safe to consume. Since it’s water soluble, you can’t overdose on it. Just watch out if you’re taking more than 2,000mg a day, as you may experience some uncomfortable digestion issues. If you experience an upset stomach or diarrhea, you should be able to find quick relief by lowering your Vitamin C intake.

No matter how much Vitamin C you decide is best for you, try to get it from a variety of sources throughout the day. Take a Vitamin C supplement with breakfast, enjoy some fresh berries at lunch and dark leafy green vegetables and maybe even another supplement at dinner. Remember that fresh, uncooked fruits and vegetables contain the highest levels of Vitamin C.
