Why vitamins K2 and D3 are essential for your health
Strong bones and healthy muscles are the foundation of movement, strength and vitality. Vitamins D3 and K2 play a key role in maintaining this balance, working together to support bone density, muscle function and cardiovascular health.
Vitamin D3 helps the body absorb calcium and phosphorus from food and maintain the balance of these minerals in the blood. It also supports normal muscle function and contributes to a healthy immune system, which is especially important during periods of low sunlight.
Vitamin K2 ensures that calcium is properly directed into the bones and teeth, instead of soft tissues or blood vessels, promoting bone strength, elasticity and long-term cardiovascular health. Together, vitamins D3 and K2 create a natural synergy that helps the body use calcium efficiently, keeping bones strong, arteries flexible and muscles functioning properly.
Both vitamins are fat-soluble and essential for calcium metabolism. Vitamin D activates proteins that depend on vitamin K, while vitamin K2 enables their proper function. Research shows that taking both together may be more effective for bone and heart health than taking either alone.
Acuraflex® K2 + D3 delivers these two essential vitamins in their natural, highly bioavailable forms – vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone-7, MK-7). Its pure, high-quality formula ensures excellent absorption and provides optimal daily intake in just one capsule. Free from gluten, soy, lactose, GMOs and artificial additives, it is suitable for daily use to help maintain mobility, strength and bone health throughout the year.

FAQ
Frequently asked questions
What is Acuraflex® K2 + D3?
Acuraflex® K2 + D3 is a food supplement that contains a carefully balanced combination of vitamins D3 and K2 in highly bioavailable forms. These two vitamins work together to support the health of bones, muscles and the cardiovascular system. Vitamin D3 contributes to the absorption of calcium and phosphorus and supports normal muscle function, while vitamin K2 directs calcium into the bones and helps prevent its accumulation in blood vessels. The product is formulated based on the latest scientific findings on the synergy of these vitamins. Acuraflex® K2 + D3 is suitable for daily use by individuals who wish to maintain bone strength and overall health in the long term.
Who should take Acuraflex® K2 + D3?
Acuraflex® K2 + D3 capsules are intended for adults who care about maintaining healthy and strong bones, especially those who are physically active, as well as women during menopause and postmenopause.
While vitamin D3 helps your body absorb more calcium, vitamin K2 ensures that calcium is directed to your bones and teeth rather than being deposited in the arteries and other soft tissues. These combined effects are essential for bone strength and proper cardiovascular function.
How does Acuraflex® K2 + D3 differ from other vitamin D supplements?
Most dietary supplements contain only vitamin D3, while Acuraflex® K2 + D3 combines D3 with vitamin K2 in a form that offers high bioavailability and longer retention in the body. This combination ensures that the calcium absorbed with the help of vitamin D3 is properly directed into the bones rather than soft tissues, promoting an optimal balance between calcium in the blood and calcium in bone tissue.
Produced in Germany according to the highest quality standards, Acuraflex® K2 + D3 is free from gluten, lactose, soy, GMOs and artificial additives. Its exceptional quality and scientifically proven synergy make it a superior choice compared to most standard vitamin D supplements.
What are the sources of vitamin D?
The synthesis of vitamin D3 takes place in the skin under the influence of sunlight, specifically UV radiation. Only a few foods significantly contribute to vitamin D intake, with oily fish being the richest dietary sources. These include, roughly in order of highest to lowest D3 content, catfish, salmon, mackerel, sardines, tuna and eel. Other sources include eggs, cooked beef liver, fish liver oils (such as cod liver oil), egg yolk and red meat.
Numerous scientific findings highlighting the many clinical benefits of vitamin D have led to increasing support for higher recommended intakes through both diet and supplementation.
Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus, helps maintain normal calcium levels in the blood, supports the maintenance of normal bones and muscle function, and contributes to the normal function of the immune system.
What are the sources of vitamin K?
Green leafy vegetables and cruciferous plants such as spinach, chard, cauliflower, kale, broccoli and cabbage are by far the best sources of vitamin K1. Other sources include vegetable oils (such as soybean, rapeseed and olive oil) and, in smaller amounts, peas, beans, tomatoes and carrots.
Menaquinones (collectively known as vitamin K2) are produced by the gut microbiota, but only a small portion of the vitamin synthesised in this way is actually absorbed in the large intestine. The main dietary sources of menaquinones are animal-based foods such as meat, egg yolks, butter and cheese, as well as legumes like fermented soybeans (natto).
Vitamin K1 contributes to normal blood clotting. Vitamin K2 contributes to the maintenance of normal bones and plays a role in regulating calcium levels in body tissues. In addition, vitamin K2 supports cardiovascular health, particularly by helping maintain the elasticity of blood vessel walls.
Is it better to take vitamins K2 and D3 together or separately?
Deficiency of both vitamins is common, as it can be difficult to obtain adequate amounts from food — especially since vitamin K2 is found mainly in foods that most people rarely consume. For this reason, dietary supplements are an excellent way to restore optimal levels of both vitamins. Studies have shown that vitamins K2 and D3 are most effective when taken together.
What are the main benefits of taking Acuraflex® K2 + D3 regularly?
Regular use of Acuraflex® K2 + D3 helps maintain normal bone density, proper muscle function and stable calcium levels in the body. Vitamin D3 supports a strong immune system and healthy musculoskeletal function, while vitamin K2 promotes the proper deposition of calcium into the bones and helps reduce the risk of calcium build-up in the arteries. Together, they support long-term mobility and bone strength.
Regular supplementation is also beneficial for individuals who spend little time in the sun or experience lower vitamin D levels during the winter months. Acuraflex® K2 + D3 offers an easy and effective way to support bone and immune health every day.
How many capsules should I take per day?
The recommended daily dose is one capsule per day, taken with a meal and a glass of water. This amount provides an optimal intake of vitamins D3 and K2 in line with the recommended nutritional values for adults. Taking the capsule with a meal containing a small amount of healthy fats can further improve vitamin absorption.
For individuals with increased vitamin D needs, it is advised to consult a healthcare professional before adjusting the dosage. Regular daily use ensures the best and most long-lasting results.
Can Acuraflex® K2 + D3 be taken together with other supplements?
Yes, Acuraflex® K2 + D3 can be combined with most other dietary supplements, especially those that do not contain high doses of vitamins D or K. When taken together with magnesium, calcium or omega-3 fatty acids, it can further support bone and cardiovascular health.
However, if you are already using supplements that contain high amounts of vitamin D, it is recommended to consult your doctor. It is important to maintain a proper balance between vitamins and minerals to ensure optimal nutrient utilisation. Acuraflex® K2 + D3 is formulated to easily fit into your existing supplement routine.
Can pregnant and breastfeeding women take Acuraflex® K2 + D3?
Acuraflex® K2 + D3 contains vitamins in generally safe amounts, but pregnant and breastfeeding women are advised to consult their doctor before taking any dietary supplement. During pregnancy and breastfeeding, the body’s requirements for vitamins D and K may be increased, but intake should always be individually adjusted.
A healthcare professional can recommend the ideal daily amount based on dietary habits and lab results. The supplement can be a valuable part of a balanced diet that supports the health of both mother and baby. However, it is always important to follow the recommended dosage.
Does Acuraflex® K2 + D3 contain allergens or artificial additives?
No, the product does not contain gluten, lactose, soy, GMOs, preservatives, or artificial colours or flavours. It is formulated to be safe for individuals with allergies or intolerances to common dietary allergens.
The capsules are plant-based and contain no animal ingredients, making them suitable for vegans. Produced in Germany under strict quality and safety control, Acuraflex® K2 + D3 is made only with carefully selected ingredients to ensure purity and high bioavailability — without unnecessary additives.
