Mistake #4: Misusing vitamins/supplements.
Sure, we triathletes have higher daily calorie needs, but do we require vitamin supplementation? According to a recent panel of experts, maybe not. As a sports dietitian, I recommend supplementation when warranted, to correct dietary deficiencies in things such as calcium, vitamin D and omega-3 fatty acids. Establish a solid daily nutrition foundation with real food first. Seek individualized advice as needed, and fill in any gaps with supplements if indicated. Supplements are not a “quick fix” for dietary insufficiencies.
