  • Microbiome Labs MegaQuinD3 Microbiome Labs MegaQuinD3

    Introducing MegaQuinD₃, a high-potency K2/D3 supplement that represents a new approach to supporting bone, heart, nerve, mitochondrial, and immune function. Give your clients far-reaching metabolic support with this synergistic vitamin K and D supplement formulation offering a myriad of health-supportive benefits! Every daily supplement regimen should include the essential vitamins D and K. Microbiome Labs combines highly bioactive and effective forms of natural vitamin K2 (MK-7) and vitamin D3 (cholecalciferol) in MegaQuinD₃Fat-soluble vitamins D and K have a synergistic interplay in several health-supportive functions. Animal and human studies focusing on genetic, molecular, and cellular aspects suggest that optimal vitamin D and vitamin K concentrations support healthy bone and heart function. Both vitamins play a critical role in calcium metabolism. Calcium absorption, assimilation, and utilization are sophisticated processes requiring adequate amounts of vitamin D3 and vitamin K2-7. Research has shown that administering vitamins D3 and K2-7 supports improved calcium absorption in the gastrointestinal system and directs calcium away from tissues into bone. Vitamin K2 supports the removal of calcium from tissues and transports it to the bone where it belongs, maintaining optimal bone health. Vitamin D3 supports and maintains intestinal calcium and phosphorous absorption for optimal bone mineral matrix formation, making vitamin D one of the most important vitamins for supporting strong, healthy bones. Vitamin D3 also plays a vital immune function-supportive role.Promotes bone healthSupports cardiovascular healthSynergistic formula to support optimal calcium absorption and utilizationSupports healthy nerve function, mitochondrial function, and immune functionHigh potency K2/D3 formulaSynergistic formulationVitamin K2-7High-dose vitamin K2 (MK-7)Natural K2-7 derived from chickpea fermentationSolvent-free during productionSoy-free, dairy-free, gluten-free, and non-GMOKosher and HalalPublished safety studiesVitamin D3Derived from LanolinBSE/TSE freeNon-GMOK2 and D3: Synergy and Sourcing Matter!Sourcing matters with supplemental K2, as synthetic K2 is pervasive on the market. We use only natural K2 in our supplements, which is the only way to produce 100% trans isomer (all K2-7). Synthetic forms of K2 can contain up to 40% cis isomer, meaning that percentage is of unknown constitution. Our form of K2 is produced from natural fermentation, making it the most biologically active and bioavailable form available.MegaQuinD₃ is a high-potency K2/ D3 supplement, combining two essential nutrients that support and maintain bone and cardiovascular health. Current research suggests that supplementing with vitamins D and K together may be significantly more supportive for bone and heart health than taking either vitamin alone.Dosing InstructionsAges 18+: Take 1 capsule daily with a meal or as recommended by your healthcare practitioner.

  • Carlson Labs Vitamin K2 MK7 120 softgels Carlson Labs Vitamin K2 MK7 120 softgels

    Description Without vitamin K2, calcium can't adequately be processed in our body to help maintain strong, healthy bones. Vitamin K2 activates certain proteins, including osteocalcin and Matrix GLA Protein (MGP), which play a role in binding calcium to the bone matrix. Without an adequate amount of vitamin K2, a significant amount of osteocalcin will remain inactive and unable to bind to calcium. Vitamin K2 also supports cardiovascular system health by promoting healthy blood clotting and directing calcium out of the bloodstream and arteries and into the bones. Build healthy bones and support optimal wellness with Carlson Vitamin K2 as MK-7.* Supports cardiovascular system health* Promotes bone and blood health* Promotes calcium absorption 90 mcg of vitamin K2 as MK-7 in a single soft gel Potency and quality guaranteed Dietary Considerations Gluten Free Preservative Free   Suggested Use Adults: Take one softgel daily at meal time.

Vitamin K Products

Vitamin K supplements help in maintaining proper blood clotting factors, keeping bones healthy and helping ward off a wide variety of illnesses and problems for people of all ages. Vitamin K is a fat soluble vitamin that comes in two naturally occurring forms: K1 and K2. Vitamin K1 can be found in many foods. Vitamin K2 is produced within the large intestine by intestinal bacteria. There are also synthetic forms of vitamin K (K3, 4 & 5) which are used medicinally. Vita Living offers Allergy Research Group Full Spectrum Vitamin K, Life Extension Super K and an impressive selection of strengths, forms and combinations of K vitamin supplementation.

Although medical professionals sometimes say that people are not likely to suffer a shortage of vitamin K because it is produced by the body, it is important to remember that it is only vitamin K2 that is produced by the body. Additionally, this process can be interfered with by improper diet, long term antibiotic use, liver disease and other circumstances. For this reason, it is a good idea to supplement natural vitamin K1 and to maintain a healthy diet that includes green, leafy vegetables, cruciferous vegetables such as cabbage, cauliflower and broccoli, and fruits such as grapes, kiwi and avocado. Parsley is especially high in vitamin K1 and should be included in the diet on a regular basis. In addition to supplementation, good natural sources of vitamin K2 include dairy products, eggs, meats and a fermented soybean food source known as Natto. Avoiding vitamin K deficiency amounts to avoiding such problems as excessive bleeding, osteoporosis and cancer. Additionally, a proper balance of vitamin K helps regulate metabolism and assist in proper production and use of insulin. For this reason, regular use of a high quality vitamin K supplement is highly recommended for optimum health. If you are taking blood thinners, please consult your physician before taking Vitamin K since it also acts as a natural blood thinner.
