COACH'S ADVICE.
- Feel free to use vitamin C in winter to avoid colds or flu. Every time I've taken vitamin C in winter, I haven't had any cold problems.
- The sun isn't really a feature of our country, especially in winter. A vitamin D supplement could make up for this lack of sunshine.
- If you feel unusually tired, it's time to check if there's something missing and get a blood test. Anyway, an athlete should have a blood test at least annually.
