What is in it
The vitamin C is plain ascorbic acid, the most studied form. Adults need about 45 mg a day, which a couple of pieces of fruit will cover, so 500 mg is a high dose by food standards.
How much is too much. Australia has not set a formal upper level for vitamin C, but the Nutrient Reference Values suggest about 1,000 mg a day from supplements as a prudent limit for adults. Higher amounts are not stored and can cause stomach upset and loose stools.
Who it suits
- Adults who want a simple 500 mg vitamin C capsule.
- People who eat little fruit and few vegetables.
Who should check first
- History of kidney stones: speak to your doctor before taking high dose vitamin C.
- Haemochromatosis or high iron levels: vitamin C increases iron absorption, so check with your doctor.
- Pregnant: the label says to consult your health professional before use.
- Taking medication: check with your pharmacist.
How to use it
Thorne's suggested use is 1 capsule, one to three times daily. Check the directions on your bottle and follow them. One or two capsules a day keeps you at or under 1,000 mg. Taking it with food is easier on the stomach.
