Introduction
Vitamin K2 (menaquinone-7, MK-7) and Vitamin D3 are two essential vitamins for maintaining overall health and well-being. While Vitamin D3 is well-known for its role in bone health, Vitamin K2 plays a crucial role in several other aspects of human health, including immune function. This article aims to provide an overview of the properties, benefits, and recommended intakes of K2 plus D3 for optimal health.
Vitamin K2 (Menaquinone-7) Information
Properties
Vitamin K2 is a fat-soluble vitamin that is naturally found in foods, particularly in foods of animal origin. It is widely available in foods such as cheese, eggs, meat, and butter. The most bioavailable and active form of vitamin K2 is menaquinone-7 (MK-7). MK-7 is derived from natto beans, which are fermented with Bacillus subtilis, causing the bacteria to produce MK-7.
Functions
Vitamin K2 is involved in several vital biological processes, including blood clotting, bone formation, and cardiovascular health. It plays a critical role in the trafficking of calcium ions in the body, ensuring that these vital minerals are delivered to where they are needed, such as bones and blood vessels, and away from areas where they can cause damage.
Bone Health
One of the most significant benefits of vitamin K2 is its role in maintaining bone health. Vitamin K2, in the form of MK-7, aids in the synthesis of骨钙蛋白 (bone Gla protein) and increases the absorption and utilization of calcium in the intestines. This combination leads to the formation of strong, healthy bones and prevents bone loss, osteoporosis, and fractures.
Immune Function
Vitamin K2 also plays a crucial role in immune function. It has been shown to have anti-inflammatory and pro-resolution properties, meaning it can help regulate the immune response and promote the resolution of inflammation. A sufficient intake of vitamin K2 may help protect against chronic diseases such as心血管 disease, autoimmunity, and certain types of cancer by maintaining a balanced immune response.
Recommendations
The recommended dietary intake (RDI) of Vitamin K2 for adults according to current guidelines is 120 mcg per day from all sources combined. However, the exact amount of MK-7 contained in foods may vary. For example, 100 grams of cheese contains on average 57 mcg of MK-7, while 3 ounces of beef liver contains 203 mcg of MK-7.
For individuals who prefer supplements, a high-quality K2 supplement containing MK-7 is recommended. A typical dose for adults is 1 softgel/day, but this may vary depending on the specific supplement and the individual's nutritional needs.
Vitamin D3 Information
Properties
Vitamin D3, short for calciferol, is a脂溶性维生素 that can be obtained from both dietary sources and supplements. It is responsible for helping the body absorb calcium and phosphorus, which are essential for maintaining bone health, muscle function, and immune health.
Functions
Vitamin D3 plays a critical role in the regulation of calcium and phosphorus homeostasis, ensuring that these minerals are available in adequate amounts for the body's various needs. It also influences the expression of over 200 genes, including those involved in immune function, muscle cell growth, and bone development.
Bone Health
Vitamin D3 is involved in the process of calcium absorption, particularly in the duodenum, the first part of the small intestine, where it promotes the absorption of calcium from food. This process is facilitated by the action of Vitamin D3 on the surface of enterocytes (intestinal cells).
Immune Function
Vitamin D3 has a profound impact on the immune system. It enhances the activity of immune cells such as macrophages, monocytes, and T-cells, which are essential for protecting the body from infectious diseases. Additionally, it stimulates the production of cathelicidins, antimicrobial peptides that are active against细菌 and fungi, further supporting the immune defense.
Recommendations
The RDI for Vitamin D3 according to the 2019 data for adults age 19+ is 600 international units (IUs) per day for people who are 60 and older or those with certain risk factors for vitamin D deficiency. Younger adults and children require less than 600 IUs per day, although this value may vary based on factors such as geographical location, skin pigmentation, and lifestyle.
For individuals who prefer dietary sources, exposure to sunlight is an effective way to produce vitamin D; however, due to the variability in UV radiation levels across different regions and the need to protect the skin from excessive sun exposure, supplements may be a more practical option for maintaining adequate vitamin D levels.
K2 Plus D3: A Winning Combination for Optimal Health
Vitamin K2 and Vitamin D3 are two essential nutrients that work together to maintain the body's calcium and phosphorus homeostasis and support various bodily functions. A daily supplement containing a balance of K2 and D3 can provide numerous health benefits, including:
- Supportive care for osteoporosis and骨骼-related disorders
- Enhanced immune function, preventing infections and reducing the risk of illness
- Improved bone quality and integrity, reducing the risk of fractures and breaks
- A strong heart and cardiovascular health
- Enhanced mental health, improving mood and cognitive function
