Can you take collagen and vitamin K2 together?

Yes — there's no known reason collagen and vitamin K2 can't be taken together, and they're commonly combined in daily formulas for women over 45. They do completely different jobs and don't compete for absorption in a way that causes a problem. There is one important exception worth stating plainly: if you take a blood thinner such as warfarin, vitamin K interacts with that medication, so you must talk to your doctor before adding any K2 — don't start it on your own.

What each one does

Collagen is the raw material your skin, bones and connective tissue lean on — a hydrolysed protein you're topping up, not something we attach a direct effect claim to. Vitamin K2 has a recognised structural role: it helps calcium reach your bones. So the two aren't doing the same job at all — one supplies protein building blocks, the other helps direct a mineral where it belongs. Pairing them is straightforward because their roles don't overlap.

Timing and how to take them

Take both once a day; there's no need to space them apart from each other. Vitamin K2 is fat-soluble, so it absorbs a little better with a meal that contains some fat — that's the one practical note. Collagen mixes easily into a cold drink and doesn't need special timing. Consistency matters more than the exact hour with either.

The blood-thinner point, again

It's worth repeating because it's the one thing that genuinely matters here: vitamin K affects how blood-thinning medication like warfarin works. If you're on an anticoagulant, a steady, predictable vitamin K intake is something your prescriber manages deliberately — so any new K2 supplement is a conversation for them, not a decision to make yourself. This isn't about collagen, which has no such interaction; it's specifically the K2.

Where Vyelle fits

Vyelle Daily Renewal already contains both — 5,000 mg of marine collagen and 90 mcg of vitamin K2 (MK-7) — disclosed on the label, in one daily drink. Because the collagen is marine (fish-derived), skip it if you have a fish allergy. And if you take a blood thinner, clear the full ingredient list with your doctor first because of the vitamin K.
