The threat of supplements for athletes in New Zealand
Supplements include pre-workouts, protein powders, vitamins, herbal remedies and products that claim to assist weight loss, to develop muscular strength or size, and to provide energy. They continue to be a serious issue for New Zealand athletes for many reasons.
The supplement industry is not regulated. Poor quality control may mean that supplement labels may not accurately list all the ingredients used within the product. This means that supplements can contain prohibited substances – they may be on the label, listed under an alternative name, or not listed at all.
In the past few years a number of athletes have tested positive to prohibited substances believed to have been ingested through supplements. Each of those athletes faced a ban from all sport of up to four years.
As an athlete you are solely responsible for every substance in your body. Before using any supplement, it’s important that you and your support team understand the risks involved.
We cannot approve the use of any supplement product. It is your responsibility to be aware of what you are taking and whether it contains prohibited substances.
Considering a supplement?
Consider the risks
What you need to understand
If you’re considering taking any kind of supplements, we recommend you understand the following first:
- Make the effort to understand your nutritional needs and try to meet these through food first.
- Seek expert advice and tell them you are an athlete who could be tested anytime.
- Supplement labels don’t always say exactly what is in a product or how much. Words like herbal and natural do not necessarily mean it is safe.
- Using incorrect doses, or thinking more is better, is dangerous for your health.
- Supplement safety and effectiveness is rarely proven in athletes under 18, those with medical conditions or who use other substances.
- If tested, remember to list all substances you have used on your paperwork.
- Athletes use all supplements at their own risk and responsibility.
Making informed decisions
Use the Guide
Before making a decision to use a supplement and to understand the risks involved, use our Supplement Decision-Making Guide.
Take a food-first approach
At Drug Free Sport New Zealand, we advocate for a food-first approach to nutrition. A planned and balanced diet can usually meet all of a competitive athlete’s nutritional needs. There is little evidence indicating that supplements are needed to complement a healthy diet, and they can pose a threat to both the health and career of athletes.
