Vitamin Basics & Tips


Vitamin D plays a crucial role in calcium absorption, bone health, and immune function. While sunlight is a primary source, many people rely on supplements like Vitamin D3 to meet daily requirements, especially in regions with limited sun exposure. Combining Vitamin D with Vitamin K (as seen in this product) can enhance calcium utilization, directing it to bones rather than arteries, which supports cardiovascular health.


Sea iodine, derived from seaweed, is vital for thyroid hormone production, regulating metabolism and energy levels. Thyroid health depends on adequate iodine intake, and deficiencies can lead to conditions like goiter or hypothyroidism. This product’s inclusion of both iodine and Vitamin K creates a synergistic blend for metabolic and circulatory wellness.


When choosing supplements, consider individual needs: those with sufficient Vitamin D levels might prioritize iodine or K. Always consult a healthcare provider to avoid over-supplementation, as excess fat-soluble vitamins (like D and K) can accumulate in the body.
