Fuel Your Winter Warmth: Iron supplementation in winter.

As winter sets in, staying warm becomes paramount for outdoor enthusiasts. Surprisingly, low iron levels may contribute to the struggle against the cold.

Iron deficiency can impede heat production and affect body temperature regulation. This concern is particularly relevant for dedicated endurance athletes training outside like runners, cyclists and triathletes, where the risk of iron deficiency is higher.

Learn how to elevate your iron intake to not only combat deficiency but also enhance your winter warmth.

Understanding the Iron-Body Temperature Connection:

  • Heat Production Impairment: Runners and triathletes, especially at elite levels, are at an increased risk of iron deficiency, potentially leading to impaired heat production.

Recognizing the Signs of Iron Deficiency:

  • Temperature Sensitivity: If you struggle to stay warm during winter activities, low iron levels might be a contributing factor.
  • Fatigue and Weakness: Iron deficiency can cause fatigue and weakness, affecting overall performance in running and triathlons.
  • Blood Test: Consult your physician for a blood test to assess iron levels and detect any deficiency.

Dietary Measures to Boost Iron Intake:

  • Iron-Rich Foods: Incorporate iron-rich foods into your diet, such as lean meats, beans, lentils, and leafy green vegetables.
  • Vitamin C Pairing: Enhance iron absorption by pairing iron-rich foods with those high in vitamin C, like citrus fruits.
  • Avoid Calcium Interference: Avoid consuming calcium-rich foods with iron-rich meals, as calcium can inhibit iron absorption.
  • Use a Daily Supplement: Consider using a high-quality daily multivitamin supplement like Form’s Multi-Vitamin that includes Iron to support your Iron levels. 

Tailoring Nutrition for Winter Warmth:

  • Personalized Diet: Work with a nutritionist to create a personalized diet plan that ensures sufficient iron intake for winter warmth.


Don't let low iron levels dampen your winter adventures. Elevate your iron intake through mindful dietary choices, recognizing the critical link between iron and body temperature regulation, especially for endurance athletes like cyclists, runners and triathletes. If you have any concerns consult a medical professional for an assessment and embrace dietary changes.
