With so many supplements out there, why does DAKE even include Vitamin A?Updated 21 days ago

Vitamin A doesn't get the cultural moment that Vitamin D or magnesium gets right now — but it's quietly one of the most commonly suboptimal fat-soluble nutrients in modern diets, and its absence creates a real ceiling on what the other fat-soluble vitamins can do. 

Here's the practical reality: the foods that actually deliver preformed Vitamin A — liver, cod liver oil, full-fat dairy, egg yolks — have been systematically reduced in most people's diets over the last few decades. Low-fat dietary guidance, reduced organ meat consumption, and the rise of plant-forward eating all contribute. Beta-carotene from vegetables gets counted on nutrition labels as Vitamin A equivalent, but the body has to convert it into usable Vitamin A — a process that is inefficient for many people and affected by genetics, gut health, and thyroid status. Retinyl palmitate is preformed Vitamin A, meaning your body absorbs and uses it directly without that conversion step, making it significantly more bioavailable.  

The deeper reason Vitamin A belongs in DAKE is the way fat-soluble vitamins work together. Vitamins A, D, and K are metabolically interdependent — they share transport proteins, compete for some of the same receptors, and regulate each other's activity. High-dose Vitamin D supplementation, which is extremely common in the health optimization world, can actually accelerate Vitamin A depletion over time. Running D without A — or K without A — is like tuning one part of an engine while ignoring what it connects to. DAKE includes Vitamin A (as retinyl palmitate, the form your body uses directly), Vitamin D, Vitamin K1, and Vitamin K2 as MK-4, all together in one capsule — dosed intentionally so the full fat-soluble stack is covered and balanced. 

Including Vitamin A isn't a checkbox. It's the difference between a fat-soluble supplement that's complete and one that's quietly working against itself.
