This study is a randomized controlled trial comparing the effects of socket grafting with crushed vitamin K2 (menaquinone)capsules versus no grafting on bone density and socket dimensions following tooth extraction. Patients are randomly assigned to one of two groups:
Study Group (Group I): Patients receive socket grafting with crushed vitamin K2 (menaquinone) capsules. The socket is covered with an absorbent sponge, and non-resorbable sutures are placed to stabilize the graft material and achieve soft tissue stability.
Control Group (Group II): Patients undergo socket healing without grafting. The socket is covered with an absorbent sponge, and non-resorbable sutures are placed over it.
Outcome measures include bone socket dimensions evaluated immediately after extraction with graft material, as well as assessment after 4 months using cone beam computed tomography (CBCT) radiographs. Additionally, core biopsies are taken at the time of implant placement.

Short communication: Can Vitamin D be supplied from the large intestine?

Article

Author: Fraser, David R. ; Fraser, David R

The discovery that vitamin D₂ is being generated by anaerobic microbial metabolism in the alimentary tract, raises the question whether such a source of vitamin D could contribute to vitamin D supply for the animal hosting this microbial production system. In ruminants, this microbial generation in the forestomach allows vitamin D₂ to be readily absorbed when it reaches the small intestine, contributing to vitamin D₂ and 25-hydroxyvitamin D₂ [25(OH)D₂] found in their tissues. In monogastric animals like humans, the microbial generation of vitamin D₂ is occurring in the large intestine. There is evidence that vitamin D hydroxy metabolites, delivered to the lumen of the colon can be absorbed. However, the parent vitamin D is more lipophilic than its metabolites, and like lipophilic vitamin K₂ being produced by bacteria in the hindgut, may be poorly absorbed by the colon mucosa. It is now apparent that colon mucosal cells have the proteins megalin and cubilin in their basal membrane. These glycoproteins perform endocytosis of circulating proteins including vitamin D binding protein [DBP]. Inside the cell, DBP binds to cytoplasmic actin and thus provides an array of high affinity binding sites for vitamin D and its functional metabolites. Any traces of vitamin D₂ that may diffuse into the colon mucosal cells from the lumen would thus be retained and accumulate on the DBP-actin. It would then be a substrate for functional hydroxylase metabolism for local endocrine action in these cells, and subsequent delivery of 25(OH)D₂ by diffusion to apo-DBP in the circulation.

Vitamin K - content in food and dietary intake among the Danes

Article

Author: Jakobsen, Jette ; Christensen, Tue ; Langwagen, Marija ; Jensen, Marie Bagge ; Poulsen, Anders

Insufficient information on the content of vitamin K2 in our foods hinder estimation of the dietary intake. We aimed to establish content of eight vitamin K vitamers, vitamin K1 (phylloquinone; PK) and vitamin K2 (menaquinones; MK-4 to MK-10) in 88 composite food samples representing dairy, eggs, meat, fish, cereals, and plant-based alternatives to dairy. Combined with PK data for other foods, the dietary intake among Danes was estimated. The unit'PKeq' is used to compensate for the difference in molecular weight for MK-4 at 445 g/mol up to MK-10 at 853 g/mol. The highest content was found in chicken thigh with skin at 53 μg PKeq/100 g followed by 49 μg PKeq/100 g in Danablue (blue cheese). The daily intake of vitamin K is 139 μg to 160 μg PKeq for adults. The highest percentage comes from PK (64 %), 27 % from MK-4, 4.6 % from MK-9, and 2.4 % from MK-8.

Efficacy of Recombinant Human Parathyroid Hormone 1–34 and Vitamin K2 Combination Therapy in Postmenopausal Osteoporosis

Article

Author: Mai, Ruopeng ; Lu, Zhaogang ; Liu, Peng ; Xia, Kun ; Zhang, Zhuo ; Gong, Wentao

Abstract:

This study aimed to assess the efficacy and safety of a combined recombinant human parathyroid hormone 1–34 [rhPTH (1–34)] and vitamin K2 therapy versus vitamin K2 alone in the treatment of postmenopausal osteoporosis. A total of 77 postmenopausal osteoporosis patients were randomly divided into two groups. Patients in one group received vitamin K2 alone, while patients in the other group received a combination of rhPTH (1–34) and vitamin K2. Bone mineral density (BMD), electrolyte levels, pain scores, bone metabolism levels, and adverse drug reactions were compared pre- and post-treatment. Both two treatments improved BMD, blood calcium concentrations, pain scores, and increased osteocalcin and osteoprotegerin levels. Notably, the combined rhPTH (1–34) and vitamin K2 treatment demonstrated superior efficacy in improving BMD and bone metabolism markers. Furthermore, there was no significant difference in the incidence of adverse reactions between the two groups, indicating the safety of the combined treatment. In summary, the combined therapy of rhPTH (1–34) and vitamin K2 exhibited more potent efficacy in the treatment of postmenopausal osteoporosis, more effectively enhancing BMD and bone metabolism markers than vitamin K2 alone, without a significant increase in adverse reactions.

Ortek to Launch Oral Care Prebiotic Soft Chew with Added Nutrients for Enamel, Bone, Immune and Cardiovascular Support

This revolutionary patent pending product combines Ortek's breakthrough microbiome oral care technology with vital nutrients to help support tooth enamel and maintain healthy bones and immune and cardiovascular systems. BasicBites Synergy Plus Soft Chews BasicBites Synergy Plus will further strengthen Ortek's ability to capitalize on opportunities in the global oral care, supplement, and prebiotic markets which last year were valued at approximately $200 billion. The company is also developing additional BasicBites line extensions that it plans to announce soon. "Our products have been well received by our loyal and growing customer base of thousands of consumers and dental professionals," said Mitchell Goldberg, President of Ortek Therapeutics, Inc. As this new product line extension shows, we continually find new ways to take advantage of our university developed microbiome oral care technology." What makes BasicBites Synergy Plus a one-of-a-kind prebiotic and nutritional supplement is its patent pending formula which includes all of the following ingredients: Arginine Bicarbonate and Calcium Carbonate which work together to create a healthy, balanced oral pH environment that protects teeth from harm caused by dry mouth–which effects 1 in 4 adults–and sugary foods and drinks. Arginine, an amino acid, nourishes the beneficial pH-raising bacteria discovered in dental plaque, resulting in immediate and sustained buffering on tooth surfaces that helps neutralize harmful plaque acids-a prebiotic process. The calcium carbonate also enriches tooth enamel and bones and plays an important role in supporting the health of cardiovascular, muscular and nervous systems. K2VITAL®, a novel K2 MK-7 formula superior to other Vitamin K2 supplements. Vitamin K2 facilitates the transport and integration of calcium into bones and teeth. It helps maintain a normal calcium balance in arteries, which may inhibit their calcification and prevent or slow the progression of arterial stiffness. This novel formulation from Kappa Bioscience maintains Vitamin K2's potency in higher pH products such as BasicBites Synergy Plus. Vitamin D3 which helps the body absorb calcium into the bloodstream and has a vital role in maintaining strong teeth and bones. It also helps support a strong immune system and respiratory and neuromuscular functions and could play a role in maintaining cardiovascular health and metabolizing blood glucose.
