Bronson Vitamin K2 + D3 Review
Vitamin K2 MK-7 Plus Vitamin D3 is presented by Bronson as a two-nutrient capsule combining vitamin D3 and vitamin K2. The product description states that it delivers 5,000 IU of vitamin D3 and 90 mcg of vitamin K2 per capsule. The page explains that vitamin D, specifically D3, which the body makes from sunlight, is essential for absorbing the calcium people depend on as they age. It notes that without D3, a person may miss out on benefits from the calcium in their diet, and that many people begin taking vitamin D3 only after they experience signs of deficiency. The page further states that D3 should not be taken alone. According to the description, vitamin D ensures that calcium is absorbed, while vitamin K2, specifically as MK-7, which the page calls the most bioavailable form, directs calcium to areas such as the bones so it can be put to good use. The page adds that without K2, absorbed calcium may be deposited in the arteries, where it can lead to calcification or other issues. Bronson concludes that vitamins K2 and D3 are the perfect pair. The product listing highlights that the formula supports heart and bone health and that vitamin D supports immune system function. It is labeled non-GMO, gluten free, and soy free. The supplement facts list a serving size of 1 capsule with 60 servings per container. The suggested use is once daily, or as directed by a health professional, for adults. Vitamin D3 is listed as cholecalciferol at 125 mcg (5,000 IU), 625% daily value, and vitamin K2 is listed as menaquinone at 90 mcg, 75% daily value. Other ingredients are modified cellulose for the capsule, microcrystalline cellulose, magnesium stearate, and silicon dioxide. The page also includes a section about Bronson, which says the company has been providing families with quality products since 1960 and describes its products as pure, high quality vitamins backed by science. The page says Bronson vitamins have been consistently mentioned by top medical professionals since its inception in 1960. Warnings on the page advise consulting a health professional before taking the product when pregnant or nursing, taking medication, or planning a medical procedure. The page also states not to use the product if the seal under the cap is broken or missing, to store at room temperature, and to keep out of reach of children. The 60 count size is listed at 9.97 dollars, with other sizes of 120, 250, and 360 count available. The current listing shows the product as sold out.
