Ergy D from Nutergia is a food supplement that stands out for its high content of vitamin D3 (cholecalciferol), derived from natural sources. This vitamin is essential for the proper functioning of the immune system and plays a crucial role in the absorption of calcium and phosphorus, vital elements for the health of bones and teeth, especially during childhood growth periods. Additionally, its composition includes virgin rapeseed oil enriched with vitamin E, ensuring the stability of vitamin D3, which is fat-soluble. This product is ideal for consumption during colder months when sun exposure decreases, as well as for vulnerable groups like growing children or individuals with bone weakness, such as the elderly and athletes. Ergy D helps maintain adequate calcium levels in the body and also supports muscular, cardiovascular health and the proper response of the nervous system.
