Vitamin D3 with K2
Mentioned 3 times across 2 shows · first heard Mar 2026 on The Dylan Gemelli Podcast.
The general take
Dr. Stephanie Estima and Rafael Gonzalez both strongly recommend D3 with K2 as a daily essential, with Estima emphasizing it's really a pro-hormone affecting sex hormones, inflammation, and cognition, while Gonzalez stresses the combination is crucial—particularly for women—because K2 helps direct calcium to bone. Both agree the pairing matters; it's not effective on its own.

…recommending essential vitamin combinations for immune and bone health
“Vitamin D is critical. I don't care how much time in combination with K. D3, K2. K2. Yeah. It's got to be in combination because, and especially good for women because it helps sequester calcium into bone. So it's really, really important in that combination, not on its own, but you got to watch it. Really, really important.”

Dr. Stephanie Estima👍 Recommends
…discussing essential daily vitamin D supplementation for hormone and inflammation support
“Vitamin D for sure. D3 with a K2. 4,000 IUs minimum per day, I would say. Most people should be taking that. They call it a vitamin. It's not really a vitamin. It's more of like a pro-hormone or a pre-hormone. So this is really important for sex hormone, reproductive hormone production. Again, inflammation, cognition. Every day? Every day. Yeah. Every day.”

…essential vitamin D and K2 supplementation for bone and immune health
“Number one is vitamin D, vitamin D3K2. I know that falls into the basics category, but most people are deficient. Vitamin D is a pro-hormone. It is important for mental health, it is important for immune function, it's important for bone health. And if you're pregnant, it's important for your baby's future teeth.”
