Vitamin D isn't really a vitamin. Your skin makes it from sunlight, and your cells use it as a signal to produce energy. Work nights and you sleep through the only window your body has to make it, so your levels quietly fall until the deficit feels like exhaustion sleep can't fix. Night Shift refills it with a 4,000 IU repletion dose, adds K2 (MK-7) to route the calcium into bone not arteries, and Rhodiola to take the edge off shift stress. The pivotal Rhodiola trial was run on physicians working night duty, the exact person this is built for.

Yes, taken as directed. 4,000 IU sits within the daily upper intake level commonly cited for adults, and every dose is paired with K2 MK-7 so the extra calcium goes to bone, not arteries. No stimulants, no melatonin, nothing to build a dependency on. GMP-certified, FDA-compliant facility, third-party tested. If you're pregnant, nursing, on medication, or managing a condition, check with your doctor first.

One vegetarian capsule a day: Vitamin D3 4,000 IU · Vitamin K2 MK-7 120 mcg · Rhodiola rosea 200 mg. Plant (HPMC) capsule, no magnesium stearate, no titanium dioxide.

One capsule a day with a meal that has some fat in it (vitamin D absorbs better with fat). Take it with your main meal before or after you sleep off a shift. No timing games, no loading phase.

Isn’t feeling wrecked just part of working nights?

It’s common, but “common” isn’t the same as “unfixable.” A lot of that wrecked feeling traces back to one
thing your schedule removes: daylight, and the vitamin D your body makes from it. Refill that and the
baseline changes.

I already take a vitamin D, why is this different?

Most drugstore D is a maintenance dose (often 1,000 IU) built for people who still get sun, and it usually
skips K2. Night Shift is a 4,000 IU repletion dose paired with K2 to route the calcium safely, built for the
deficit a night schedule actually creates.

I’ve tried coffee, melatonin, everything. Why would this work?

Because those treat the symptoms. Caffeine masks the crash and wrecks your day-sleep; melatonin only
touches sleep. None of them refill the vitamin D your schedule is draining, which is the thing underneath
the exhaustion.

Is 4,000 IU safe to take every day?

4,000 IU sits within the commonly cited daily upper intake level for adults, and the K2 MK-7 is included
specifically to keep the calcium that vitamin D moves going to your bones rather than your arteries. If you
have a medical condition or take medication, check with your doctor first.

Do I need bloodwork first?

You don’t need it to start, but it’s never a bad idea. Many people who work nights run low simply because
of the schedule. If you want a number, ask for a 25-hydroxyvitamin D test at your next visit.

How long until I feel it?

Many people notice the afternoon crash softening within the first couple of weeks, with day-sleep and
week-long stamina building over the following weeks. It’s a refill, not a stimulant, it builds.
