What supplements should I take on the carnivore diet to ensure optimal health and nutrient density? Given the stringent nature of this dietary regimen, which predominantly consists of animal products, are there specific nutrients or vitamins that one might be deficient in? For instance, could a lack of variety in food sources lead to insufficient intake of essential vitamins such as C or K? Moreover, what role does magnesium play in this diet, and could supplementation provide benefits for muscle function and overall well-being? Additionally, should one consider omega-3 fatty acids, particularly if the diet excludes certain fatty fish? How vital is it to monitor electrolyte levels, and might supplementing with potassium or sodium be necessary to prevent symptoms of imbalances? Exploring the need for iodine supplementation becomes crucial as well, given its importance in thyroid function. How does individual variation among dieters impact supplement needs, and is personalized advice advisable?
