OstroVit Vitamin D3 4000IU + K2 VEGE is a high-quality dietary supplement combining two essential fat-soluble vitamins in a convenient vegan capsule form. This product is specially designed to support bone health and normal calcium absorption through a synergistic blend of vitamin D3 from Icelandic moss and vitamin K2 MK-7 from natural fermentation. With 120 capsules per package, it provides a long-lasting supply of these critical nutrients that many people find difficult to obtain in sufficient amounts from their daily diet.

Active ingredients and science

Vitamin D3 from Icelandic moss (Cholecalciferol)

Vitamin D3 in this formulation is derived from natural Icelandic moss, making it a plant-based alternative to traditional D3 from animal sources. This form of vitamin D3, known as cholecalciferol, is identical to the form produced by the body when the skin is exposed to sunlight. With 4000IU per capsule (equivalent to 100 micrograms), this product provides a significant daily dose of this critical vitamin.

Vitamin D3 plays a central role in calcium homeostasis, which is the process by which the body regulates calcium levels in the blood. This vitamin is necessary to enable calcium absorption in the small intestine, a process entirely dependent on the presence of vitamin D3. Without sufficient vitamin D3, the body cannot effectively absorb calcium from food, regardless of how much calcium is consumed. This makes vitamin D3 a fundamental nutrient for skeletal integrity and strength.

Vitamin D3 also functions as a hormone precursor, meaning the body converts it into an active hormone form called calcitriol. This hormone not only regulates calcium and phosphate metabolism but also influences many other physiological processes in the body. Vitamin D3 contributes to normal immune system function and normal muscle function, two areas particularly important for older adults and active individuals.

Vitamin K2 MK-7 from Bacillus subtilis natto

Vitamin K2 in this formulation is specifically menaquinone-7 (MK-7), a long-chain form of vitamin K2 produced through natural fermentation of the Bacillus subtilis natto strain. This is the same process used to create traditional Japanese natto, a fermented soybean product known for its high K2 MK-7 content. This natural production method ensures the authenticity and bioactivity of the vitamin.

Vitamin K2 MK-7 is a long-chain menaquinone particularly effective at reaching tissues far from the liver, including bones and blood vessels. Unlike vitamin K1, which is mainly involved in blood clotting, vitamin K2 plays an important role in activating proteins involved in bone mineralisation and tissue calcification. Vitamin K2 MK-7 contributes to normal bone density by activating osteocalcin, a protein essential for binding calcium to the bone matrix.

This form of vitamin K2 also has a longer half-life in the body compared to other forms of vitamin K, meaning it remains active over longer periods. This makes MK-7 a particularly effective form for long-term skeletal monitoring and vascular health. Vitamin K2 MK-7 supports normal bone density and normal blood clotting, two critical physiological functions.

Inulin as a prebiotic fibre

Inulin is a natural prebiotic fibre included in this formulation. This ingredient acts as nourishment for beneficial bacteria in the gut microbiota, promoting a healthy intestinal ecosystem. A well-balanced gut flora is important for optimal nutrient absorption, including the absorption of the fat-soluble vitamins D and K present in this product.

Plant-based capsule shell of HPMC

The capsules are made of hydroxypropyl methylcellulose (HPMC), a plant-based material that is completely vegan and free from animal products. HPMC is a high-quality, well-tolerated substance that dissolves easily in the gastrointestinal tract and enables effective release of the active ingredients. This plant-based shell makes the product suitable for vegans and vegetarians.

Benefits and applications

Support for bone health and bone density

The primary benefit of this combination of vitamin D3 and K2 is their synergistic effect on bone health. Vitamin D3 facilitates calcium absorption, while vitamin K2 activates proteins necessary for incorporating this calcium into the bone matrix. Together, these two vitamins work to maintain normal bone density and skeletal integrity, especially important for older adults and those concerned about long-term bone health.

Optimal calcium metabolism

This product supports normal calcium metabolism by ensuring the body can absorb and utilise calcium effectively. Without adequate vitamin D3, calcium from food cannot be properly absorbed, leading to suboptimal bone density and potential mobilisation of calcium from bones. This product addresses this issue by providing a potent dose of vitamin D3 along with vitamin K2 to ensure the absorbed calcium is used correctly.

Support for normal muscle function

Vitamin D3 contributes to normal muscle function, an often overlooked aspect of vitamin D’s role in the body. Muscle weakness is a common problem among older adults and can increase the risk of falls and injuries. By supporting normal muscle function, this product can contribute to better mobility and functional capacity.

Support for normal immune function

Vitamin D3 contributes to normal immune system function, a role that has become increasingly recognised in recent years. Vitamin D receptors are present on many immune cells, and vitamin D plays a regulatory role in both innate and adaptive immune responses. Maintaining optimal vitamin D status can support a well-functioning immune system.

Long-term well-being and quality of life

For older adults and active individuals, maintaining bone health, muscle function, and immune function is critical to preserving quality of life and independence. This product addresses all these areas by providing two essential vitamins that are often insufficient in modern diets.

Quality and manufacturing

Plant-based formulation

This product is entirely vegan, with plant-based capsules made of HPMC and vitamin D3 from Icelandic moss instead of lanolin from sheep. Vitamin K2 is produced through natural fermentation, making it a completely plant-based source of this important nutrient. This makes the product suitable for vegans, vegetarians, and anyone who prefers plant-based supplements.

Natural sources of active ingredients

Both vitamin D3 and vitamin K2 come from natural sources rather than synthetic ones. Vitamin D3 from Icelandic moss is an authentic plant-based source, and vitamin K2 MK-7 is produced through the same fermentation process used to create traditional natto. This focus on natural sources ensures the product is as close to natural nutrient sources as possible.

Manufacturing standards and safety

OstroVit is an established brand known for its commitment to quality and safety. The product is manufactured according to strict standards to ensure purity and potency. The packaging contains 120 capsules, each providing an exact dose of the active ingredients.

Allergen information

This product is manufactured in a facility that handles milk (including lactose), soy, peanuts, other nuts, sesame seeds, gluten-containing grains, eggs, shellfish, and fish. Although the product itself does not contain these ingredients, cross-contamination risks exist for those with severe allergies. Consumers with known allergies should carefully check the ingredient list and consult a doctor or pharmacist before use.

Who is the product suitable for?

Older adults over 75 years

This product is particularly designed for older adults, a population that often has reduced ability to synthesise vitamin D from sunlight exposure and may have decreased calcium absorption due to age-related changes in the gastrointestinal tract. Older adults also have an increased risk of bone density problems and can benefit from the synergistic support for bone health provided by this product.

Vegans and vegetarians

For vegans and vegetarians, it can be challenging to obtain sufficient vitamin D3 and K2 from diet, as many traditional sources are animal-based. This entirely plant-based formulation provides these critical vitamins from plant sources, enabling vegans and vegetarians to maintain optimal status of these nutrients.

Individuals with limited sunlight exposure

People living at high latitudes, working indoors, or for other reasons with limited sunlight exposure may have difficulty producing enough vitamin D from sunlight. This product provides a potent dose of vitamin D3 to compensate for this limited endogenous production.

Active individuals and athletes

Active individuals and athletes can benefit from the muscle support provided by vitamin D3, as well as the skeletal support from the combination of D3 and K2. These vitamins are important for maintaining muscle strength and bone density during intensive training.

Individuals concerned about long-term skeletal health

Anyone proactive about their skeletal health and wishing to ensure optimal bone density and skeletal integrity can benefit from this product. By providing two essential vitamins often insufficient in modern diets, this product can support long-term skeletal health and well-being.
