Elite athletes follow highly structured supplement routines designed to support training, recovery, and overall health. Team GB rower Heidi Long recently gave BBC Sport an inside look at the vitamins and supplements she takes every day. Her routine offers a rare, transparent glimpse into the nutritional strategies that underpin elite sport performance.

Why Elite Athletes Rely on Supplements
For professional athletes, the physical demands of daily training push the body to its limits, often creating nutritional needs that are difficult to meet through food alone. High training volumes can deplete key micronutrients such as iron, vitamin D, and magnesium, which play critical roles in energy production, bone health, and muscle function. Supplements are used strategically to maintain optimal levels of these nutrients, especially during intense training blocks or periods when dietary variety is restricted.
It is important to note that supplements are not a replacement for a balanced diet — they are intended to complement one. Sports nutrition experts generally advise that whole foods should remain the foundation of any athlete's dietary plan, with supplements stepping in only where genuine gaps exist. For elite competitors like Long, every marginal gain matters, and ensuring the body has all the micronutrients it needs is considered a non-negotiable part of professional preparation.
The Anti-Doping Challenge in Supplement Use
One of the most significant considerations for elite athletes when choosing supplements is the risk of inadvertent doping violations. The supplement industry is not as tightly regulated as pharmaceuticals, meaning products can sometimes be contaminated with substances that appear on the World Anti-Doping Agency's prohibited list. For athletes competing at the highest levels, even an accidental ingestion of a banned compound can result in a lengthy suspension, regardless of intent.
To manage this risk, many elite athletes and their support teams rely only on supplements that carry third-party batch-testing certifications, such as those bearing the Informed Sport or NSF Certified for Sport labels. These certifications provide a higher level of assurance that a product does not contain prohibited substances. The fact that athletes like Long are open about their supplement routines also helps normalize conversations around transparency in sport nutrition, which is increasingly encouraged by governing bodies and sports scientists alike.
What Everyday Exercisers Can Learn From Elite Routines
While the supplement regimens of Olympic athletes are tailored to extraordinary physical demands, there are practical lessons that recreational exercisers can draw from them. Vitamin D supplementation, for example, is widely recommended for people in regions with limited sunlight exposure, regardless of fitness level. Similarly, omega-3 fatty acids have well-documented benefits for cardiovascular health and inflammation management that extend well beyond the world of professional sport.
However, the key takeaway for most people is not to replicate an athlete's exact routine, but to approach supplementation with intention and evidence. Before adding any supplement to a daily routine, it is worth identifying a specific nutritional need — ideally through a blood test or consultation with a healthcare professional — rather than assuming more is better. What works for a high-performance rower training twice a day is unlikely to be the right formula for someone exercising a few times a week, and personalisation is the foundation of any sensible nutrition strategy.
Why it matters
With the global sports nutrition industry worth billions of pounds and growing rapidly, understanding what athletes actually put in their bodies has broad public relevance. Stories like Heidi Long's help cut through the marketing noise and offer a grounded, real-world perspective on how supplementation fits into a professional lifestyle. For everyday people navigating a crowded supplement market, this kind of transparency from trusted athletes can be genuinely informative.
Common questions
Are the supplements elite athletes take safe for regular people to use?
Many supplements used by elite athletes, such as vitamin D or omega-3s, are widely considered safe for the general population. However, dosages and specific formulations suited to an athlete training at high volumes may not be appropriate for people with more moderate activity levels, so professional guidance is always advisable before starting any new supplement.
How do athletes like Heidi Long make sure their supplements are safe for competition?
Elite athletes typically use supplements that have been independently batch-tested by certified organisations, which screen for substances banned under anti-doping rules. Their coaches and nutritionists also play an active role in vetting products before they are approved for use during training or competition.
What to take away
- Personalisation Is Key
Rather than copying an athlete's supplement stack, focus on identifying your own nutritional gaps — a simple blood test can reveal deficiencies that are worth addressing.
- Quality Over Quantity
If you do take supplements, look for products with credible third-party certification to ensure you are getting what the label claims and nothing harmful.
- Watch Athlete Transparency
As more elite athletes openly discuss their nutrition routines, this growing transparency can help consumers make more informed, evidence-based choices in an often misleading supplement market.
