Daniil Medvedev has shared his thoughts on top players like Iga Swiatek using supplements during intense matches. The Russian star believes this is completely normal. He explained that the high intensity of tennis causes fatigue, leading players to take vitamins to stay strong.
One of the most memorable moments in tennis came during the 2023 Cincinnati Final. Novak Djokovic shouted “creatinaaaa” while facing Carlos Alcaraz in a long 3-hour-49-minute match. This moment went viral. Later, Djokovic spoke about his frustration with existing supplements and launched his own brand, SILA, which he claims is the most advanced in the world.
It’s not a big deal. Look, you get sick playing tennis. In normal life, you take a paracetamol, it’s fine. In tennis, you get sick, you have a match the next day, you try to take vitamin C, vitamin D, vitamin B, paracetamol, anything that helps. And there you have it, you have 10 just because you’re sick. So I wouldn’t be surprised to see 30, so I’m not surprised to see 14. In fact, I would be surprised if I saw someone at the top of the rankings putting down four supplements [on their declaration form]. I would be really shocked.
Daniil Medvedev said on National News
Recently, tennis has faced more scrutiny over supplements and banned substances. In 2024, two major doping scandals shook the sport. Jannik Sinner and Swiatek were both suspended after testing positive due to contamination.
Swiatek’s issue came from a tainted sleeping pill, leading to a one-month ban. Sinner’s case was more controversial. He tested positive for clostebol, allegedly from his physiotherapist, and received a three-month suspension starting February 15.
Iga Swiatek prevails against Elina Svitolina in Miami
World No. 2 Iga Swiatek took another step toward her first title of the year with a tough 7-6(5), 6-3 win over Elina Svitolina. The Polish star defeated the No. 22 seed from Ukraine in the Round of 16 at the Miami Open. The match lasted 2 hours and 5 minutes and ended just after midnight on Tuesday.
Swiatek is still in the race for her second Miami Open title. She won this tournament in 2022, completing the Sunshine Double by winning both Indian Wells and Miami. Only three other women—Steffi Graf, Kim Clijsters, and Victoria Azarenka—have achieved this feat.
Although Swiatek has not won a title in 2025, she leads the tour in main-draw match wins. Her victory over Svitolina was her 21st of the season. This puts her ahead of Mirra Andreeva and Aryna Sabalenka, who each have 20 wins.
Swiatek has a strong record against Ukrainian players, with 13 wins and just one loss. Her only defeat came against Svitolina at Wimbledon in 2023. In the quarterfinals, she will face 19-year-old wild card Alexandra Eala from the Philippines.
Daniil Medvedev’s recent struggles explained
Former World No.1 Daniil Medvedev has been struggling not just in 2025 but also for most of the 2024 season. The Russian has not won an ATP title in over 12 months, with his last trophy coming at the 2023 China Open.
Medvedev has built a reputation as a hard-court specialist throughout his career. Most of his titles have come on hard courts, including his US Open victory in 2021 and the ATP Finals win in 2020.
However, his title drought on hard courts speaks volumes about his struggles. In 2024, Medvedev reached the finals of two major events, the Australian Open and Indian Wells. However, he lost both matches to Jannik Sinner and Carlos Alcaraz, respectively.
Medvedev has often been second best to these two rising stars over the past two seasons. His only victory against either of them came against Sinner in the 2024 Wimbledon quarterfinals.
