Vitamins & Supplements: buying guide

Do you need a vitamin supplement?

Food comes first. The US National Institutes of Health Office of Dietary Supplements (NIH ODS) says most studies have found multivitamins have little or no effect on health outcomes in people who already eat well. A supplement is more likely to help if your diet is limited, for example a low-kilojoule or strict vegan diet, or when a health professional recommends one.

Vitamin D is the most common exception people ask about. Australia's Nutrient Reference Values note that most people maintain their vitamin D through sunlight exposure, and the Australian Institute of Sport lists vitamin D as a "medical supplement" alongside iron, calcium, zinc and folate. If you think you are low, ask your GP about a blood test before choosing a dose.

Check the dose, not just the name

  • Vitamin D. Labels use IU or micrograms (1 mcg equals 40 IU). The upper level of intake for adults in Australia is 80 mcg (3,200 IU) a day, and the US limit is 100 mcg (4,000 IU). Check the strength per capsule against these limits, and use high strengths only on your doctor's advice.
  • Vitamin B6. The TGA warns that peripheral neuropathy (nerve damage causing tingling or burning) may occur at intakes of 50 mg a day or even lower, and requires a warning on products above 10 mg a day. Add up B6 across every product you take, including multivitamins and mineral formulas.
  • Doubling up. The NIH ODS advises checking that your total intake from fortified foods and all supplements stays under the upper limit for each nutrient.

Who should check with a doctor first

If you take warfarin, talk to your doctor before using any product with vitamin K, including vitamin D and K2 combinations, because vitamin K can reduce warfarin's effect. The NIH ODS also advises smokers to avoid multivitamins high in beta-carotene or vitamin A. If you are pregnant, a pregnancy-specific product is usually more appropriate than a general multivitamin.

Vitamins & Supplements: questions and answers

Do I need a multivitamin if I eat well?
Probably not. The NIH Office of Dietary Supplements says most studies have found multivitamins have little or no effect on health outcomes. They may help people who eat very little, follow a strict vegan or low-kilojoule diet, or have been advised to take one by a health professional. If your diet is varied, spend the money on food first.
How much vitamin D should I take a day?
Australia's adequate intake for adults is 5 mcg (200 IU) a day up to age 50, 10 mcg from 51 to 70 and 15 mcg over 70, and the upper level is 80 mcg (3,200 IU). Most people get much of their vitamin D from sunlight. Use higher-strength products only after a blood test and on your doctor's advice.
Can I take vitamin K2 if I'm on blood thinners?
Check with your doctor first. The NIH Office of Dietary Supplements says vitamin K can reduce the effect of warfarin, and advises anyone taking warfarin to talk to their health care provider before using a supplement that contains vitamin K. That includes popular vitamin D3 and K2 combinations. Do not start or stop vitamin K on your own while taking this medicine.
Is it safe to take vitamin B6 every day?
At low doses, generally yes, but more is not better. The TGA says peripheral neuropathy may occur at 50 mg a day or even lower, and products with more than 10 mg a day must carry a warning. From June 2027, products with 50 to 200 mg a day will need pharmacist advice. Add up B6 across all your supplements.
