An estimated 100 trillion microorganisms live in the human gut, and these bacteria are responsible for a variety of metabolic functions, including the synthesis of key vitamins. The specific form of vitamin K that is synthesized by intestinal bacteria is menaquinone, also known as vitamin K2. This essential fat-soluble vitamin plays a crucial role beyond just blood clotting, impacting bone and cardiovascular health.

According to research, the human intestinal flora is responsible for synthesizing specific B and K group vitamins. Do microbiota produce vitamin K? Yes, specific bacteria in the gut play a crucial role in producing menaquinones (vitamin K2), which significantly contribute to our body's vitamin K levels.

Research consistently shows that the vitamin K2 content in dairy is directly correlated with its fat content, making full-fat versions a better source. This guide will detail exactly which dairy products are high in vitamin K, helping you make informed nutritional choices for better bone and cardiovascular health.

Decades of research have established that the synthetic form of vitamin K, known as K3 or menadione, is toxic to humans. Therefore, despite its past use, there is no longer a K3 supplement available or approved for human consumption due to significant safety concerns.

Scientific research confirms that certain probiotic bacteria within the human gut can synthesize vitamin K2, a form vital for bone and cardiovascular health. This raises the question of whether supplementing with probiotics can reliably boost your overall vitamin K status.

According to extensive nutritional data, standard, unfortified almond milk contains virtually no vitamin K. While whole almonds provide some of this essential nutrient, the milk-making process heavily dilutes it, leaving little to none in the final product.

A 100-gram serving of farmed Atlantic salmon provides only about 0.5 micrograms of vitamin K, a minimal amount compared to many other foods. While salmon is a nutritional powerhouse, it is not considered high in vitamin K.

Approximately 78% of people with cystic fibrosis who are not supplemented with vitamin K have a deficiency, highlighting the importance of understanding the causes of malabsorption. For individuals, knowing on what type of diet is most risk for malabsorption of vitamin K is essential for preventing complications related to this vital nutrient, which is crucial for blood clotting and bone health.
