Factors affecting the quality and potency of nutritional supplements

There are many factors that can affect the quality and potency of nutritional supplements. Some of these factors relate directly to their preparation and storage. 

  • If the label of the product or ingredients does not specify clearly how they are to be stored, always check with the manufacturer.
  • Oxygen, sunlight, moisture will all affect the integrity of nutritional supplements. In general, keeping the supplements in its original packaging, together with the moisture absorbing sachets, in a cool dry place, away from sunlight, will ensure that the quality and potency of it is not affected. Especially vulnerable to oxidation are Vitamin C tablets.
  • Only supplements that are meant to be refrigerated (probiotics for example), should be kept in a fridge otherwise the high moisture levels will affect the potency and integrity of the supplement.
  • Combining supplements in the same container may also be detrimental as certain ingredients are more reactive (such as certain acids) and they will influence other supplements. 
  • Always check the expiry date as supplements lose potency and nutritional benefits with time.

As always, I advise all my patients to purchase good quality supplements that are TGA approved. I also advise against self-prescribing as many natural remedies, including nutraceuticals may cause serious health issues if taken incorrectly. As practitioners we are required to assess each patient individually to ensure that whatever prescription we make will not interact with other medications and supplements and will not harm the patient.
