What to know before you buy a vitamin C supplement

Types of vitamin C

Vitamin C is available in several types. The most common forms found in supplements are ascorbic acid (L-ascorbic acid, L-ascorbate), sodium ascorbate and calcium ascorbate.

  • Ascorbic acid is the purest form of vitamin C because it stands alone as an isolated molecule. It’s also the most commonly used form in supplements because it’s easily absorbed by the body.
  • Sodium ascorbate is ascorbic acid with a sodium molecule attached to help lessen its natural acidity. It’s an ideal alternative if you find that ascorbic acid causes heartburn or other stomach upset. If you’re monitoring your sodium intake, though, it may be a poor choice.
  • Calcium ascorbate combines ascorbic acid and calcium. It reduces the acidity of the ascorbic acid on its own, making it excellent if you have an extremely sensitive stomach or can’t tolerate other vitamin C types due to illness.

In multivitamins that contain vitamin C, you can also find other mineral ascorbates, including zinc ascorbate, magnesium ascorbate, chromium ascorbate, molybdenum ascorbate and manganese ascorbate. Take note of the amount of the other minerals you’re getting in a mineral ascorbate vitamin C supplement to make sure you don’t exceed the recommended daily values.

Additives

You might assume a contains nothing but some form of vitamin C, but many formulas include added ingredients. Fillers are often used to help bind a supplement’s ingredients together. However, some fillers and additives are best avoided.

Stay away from vitamin C supplements that contain:

  • Hydrogenated oils.
  • Artificial colors.
  • Titanium dioxide.
  • Magnesium stearate.
  • Added sugar.

Dosage

Vitamin C supplements come in dosages usually ranging from 25 to 1,500 milligrams. You typically shouldn’t take more than 2,000 mg of vitamin C per day because your body only absorbs so much at a time. Vitamin C is water-soluble, so your kidneys flush out the excess. This is why it’s best to take smaller doses of vitamin C throughout the day rather than a single large dose.

What to look for in a quality vitamin C supplement

Supplement form

Vitamin C supplements come in several forms, though the most common are powder, chewable tablets, pills, capsules and gummies. All forms can effectively deliver vitamin C, but some are harder on the stomach than others.

Pills and capsules often cause nausea, so you may prefer chewable tablets or gummies, which usually have a tasty fruit flavor. Powders are often easier to digest, too, but you have to mix them with a liquid and drink the mixture.

Delayed, timed or sustained-release formula

Vitamin C supplements come in several formulas that affect how your body absorbs the vitamin C.

If you’re having trouble remembering to take a few small doses throughout the day, delayed, timed or sustained-release capsules are an excellent option since they don’t release their dosage all at once. The capsules have a coating made of fat, sugar and wax that breaks down and slowly releases the vitamin C at its center, so you get a small amount at a time.

Vegan

If you aren’t comfortable consuming animal products, choose a vitamin C supplement certified as vegan. Supplement capsules not certified vegan may contain gelatin derived from animals.

How much you can expect to spend on vitamin C supplement

You can pay 5 to 10 cents per dose in pill, capsule, tablet or gummy form. Powdered supplements generally cost $12-$20 per pound.
