"D3 + K2 combo strengthens bones and supports healthy arteries"
Vitamin D aids calcium absorption and K2 (MK-7) helps direct calcium to bone; this combo is well-supported, not exotic.
Examine.com Vitamin K2 summary -
"5,000 IU D3 dose is optimal for daily use"
5000 IU is 5x the standard adult RDA and meant for correcting deficiency, not routine daily maintenance for most healthy people.
Internal: dose comparison vs NIH Vitamin D fact sheet -
"Sunflower oil enhances absorption of fat-soluble vitamins"
Any dietary fat aids absorption of D3/K2; sunflower oil isn't proven superior to other carrier oils for this purpose.
Consumer advice
Vitamin D3 + K2 is a legitimate, well-studied combo for bone and cardiovascular health, especially if you're deficient in D (get a blood test to check). 5000 IU is a high daily dose — most healthy adults need 1000-2000 IU unless a doctor recommends more, so don't just default to the highest dose available. Shop by price per softgel across brands (NatureWise, Sports Research, NOW Foods all sell similar D3+K2 combos) since this ingredient pair is widely available and not unique to this brand. Skip the subscription unless you're sure you'll use it regularly — cancellation friction varies by retailer.
Claims vs Evidence
MODEST1 of 2 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
