Dr. Jacob's Vitamin D3K2 Oil

Dr. Jacob's Vitamin D3K2 Oil is a popular dietary supplement specializing in bone and immune system health. The product was first introduced to German pharmacies in 2015 by Dr. Jacob's Medical GmbH, a company that has been a pioneer in health liquid supplements since its founding in 1997. The oil is specifically formulated with high-quality ingredients, including pharmaceutical-grade Vitamin D3 and Vitamin K2 (all-trans MK-7), which are known for their high bioavailability.

The product is manufactured in Germany, maintaining strict quality standards typical of German-pharmacy brands. While the final production is based in Germany, the vitamins themselves are sourced from European partners—specifically, the Vitamin D3 is produced in Germany and the Vitamin K2 often originates from Norway. The carrier oil used is an MCT oil derived from coconut oil, also sourced within the EU.

Dr. Jacob's Medical GmbH remains an independent, family-owned business. It was founded by Dr. Ludwig Manfred Jacob and his father, Dr. Karl Otto Jacob. The company is headquartered in Taunusstein, Germany, and continues to be led by the founding family, emphasizing ethical sourcing and natural health concepts.
