Expert Contributions
Gaining insights from professionals can provide deeper understanding and practical strategies for maintaining nutrient balance on a vegan diet.
Dr. Laura Thompson, Registered Dietitian
“Vitamin B12 is one of the most critical nutrients for vegans to monitor. Since it’s primarily found in animal products, fortified foods or supplements are essential to prevent deficiency, which can lead to anemia and neurological issues.”
Dr. Michael Lee, Nutritionist
“Calcium and Vitamin D are vital for bone health. Vegans should include fortified plant-based milks, leafy greens, and consider supplements, especially if sun exposure for Vitamin D synthesis is limited.”
Dr. Emily Davis, Sports Nutritionist
“Omega-3 fatty acids, particularly EPA and DHA, are important for heart and brain health. Vegans can obtain ALA from flaxseeds and chia seeds, but consider algae-based supplements to ensure adequate EPA and DHA levels.”
Dr. Robert Harris, Endocrinologist
“Iodine is essential for thyroid function. Vegans can include iodized salt or sea vegetables in their diet, but it’s important to monitor intake to avoid both deficiency and excess, which can affect thyroid health.”
