Photo by <a href=\"https:\/\/unsplash.com\/@mvalls12\">Monica Valls<\/a> on <a href=\"https:\/\/unsplash.com\/\">Unsplash<\/a>.<\/p>\n\n<h2 class=\"wp-block-heading has-custom-font-size\" style=\"font-family:Georgia, serif;font-size:clamp(26px, 3vw, 36px);font-weight:400;line-height:1.2\">What the D3 name means<\/h2>\n\n<p class=\"has-custom-font-size wp-block-paragraph\" style=\"font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.294), 17px);line-height:1.8\">The NIH Office of Dietary Supplements identifies D2 as ergocalciferol and D3 as cholecalciferol. These are forms of vitamin D. A product labelled D3 therefore supplies a form name, but the front label still may not show the declared amount, excipients or complete formulation. Read those fields separately rather than treating D3 as a full product specification.<\/p>\n\n<h2 class=\"wp-block-heading has-custom-font-size\" style=\"font-family:Georgia, serif;font-size:clamp(26px, 3vw, 36px);font-weight:400;line-height:1.2\">What the K2 name means<\/h2>\n\n<p class=\"has-custom-font-size wp-block-paragraph\" style=\"font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.294), 17px);line-height:1.8\">NIH describes vitamin K as a family that includes K1 and menaquinones, commonly called K2. K2 includes named forms such as MK-4 and MK-7. Those form names are not the same as an amount. If a combination product says only K2, the exact form may still need clarification from its full ingredient declaration.<\/p>\n\n<h2 class=\"wp-block-heading has-custom-font-size\" style=\"font-family:Georgia, serif;font-size:clamp(26px, 3vw, 36px);font-weight:400;line-height:1.2\">Why a combination name is incomplete<\/h2>\n\n<p class=\"has-custom-font-size wp-block-paragraph\" style=\"font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.294), 17px);line-height:1.8\">A D3 + K2 title identifies two ingredient families, not a universal recipe. Two combination labels can differ in the form of K2, the declared quantities, the capsule or liquid format and other ingredients. Record each field before treating the descriptions as comparable. A larger pack count does not resolve any of those differences.<\/p>\n\n<h2 class=\"wp-block-heading has-custom-font-size\" style=\"font-family:Georgia, serif;font-size:clamp(26px, 3vw, 36px);font-weight:400;line-height:1.2\">Keep ingredient information separate from a benefit promise<\/h2>\n\n<p class=\"has-custom-font-size wp-block-paragraph\" style=\"font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.294), 17px);line-height:1.8\">An educational description of vitamins is not evidence that a particular unconfirmed product delivers an advertised outcome. A formulation-specific claim needs applicable evidence and review. This page does not answer whether an individual needs either ingredient or the combination, and it does not establish a preferred ratio or timing schedule.<\/p>\n\n<h2 class=\"wp-block-heading has-custom-font-size\" style=\"font-family:Georgia, serif;font-size:clamp(26px, 3vw, 36px);font-weight:400;line-height:1.2\">Personal questions need a different process<\/h2>\n\n<p class=\"has-custom-font-size wp-block-paragraph\" style=\"font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.294), 17px);line-height:1.8\">NIH&#8217;s fact sheets include safety and medication-interaction information. Those topics cannot be resolved from a front-of-pack combination name. Personal suitability should be discussed with a qualified professional using the actual label and relevant circumstances privately. No medication changes, dosing advice or personal health assessment are provided here.<\/p>\n\n<h2 class=\"wp-block-heading has-custom-font-size\" style=\"font-family:Georgia, serif;font-size:clamp(26px, 3vw, 36px);font-weight:400;line-height:1.2\">Arcvita&#8217;s current product status<\/h2>\n\n<p class=\"has-custom-font-size wp-block-paragraph\" style=\"font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.294), 17px);line-height:1.8\">D3 + K2 is a priority family in the planned Arcvita range.
