Why I Take This

Here’s the reality: most dads are vitamin D deficient. We work indoors, we live in climates that see actual winter, and even in summer, sunscreen (which we should use) blocks D synthesis. Vitamin D isn’t just about bones — it supports immune function, mood, testosterone levels, and muscle recovery. It’s one of the most universally recommended supplements by doctors.

Why Momentous?

Momentous is the official supplement partner of the NFL, MLB, and NHL — and they’re NSF Certified for Sport. That means every batch is independently tested for purity, potency, and banned substances. If it’s good enough for professional athletes, it clears my bar. The brand got a major visibility boost from the Huberman Lab podcast, which is how I first heard about them.

The 5,000 IU Dose

5,000 IU is a common therapeutic dose for adults who are deficient or borderline. It’s not mega-dosing — it’s the amount many functional medicine doctors recommend for adults who don’t get regular sun exposure. That said, get your levels tested if you haven’t. A simple blood test from your annual physical can confirm if you need supplementation.

My Experience

One capsule daily with a meal that contains fat (vitamin D is fat-soluble). The capsules are small and easy to swallow. No taste, no side effects. I take it alongside my other morning supplements and don’t think about it again.

After several months of consistent supplementation, my last blood panel showed optimal D levels — up from borderline deficient. That’s a measurable result.
