How should Kale be prepared or consumed (e.g., tea, tincture, capsules, tablets)?

Kale is a versatile vegetable that can be prepared and consumed in various ways, offering flexibility in incorporating it into one’s diet. Raw kale is commonly used in salads, sandwiches, or smoothies, providing a crisp texture and retaining its nutrients. Cooking kale, whether by steaming, sautéing, or baking, can soften its texture and slightly alter its taste, making it more palatable for some.
