How much vitamin K2 per day for women over 50?

There's no formal recommended daily amount set specifically for vitamin K2 — official reference values cover vitamin K as a whole rather than the K2 form on its own. In practice, supplements using the well-absorbed MK-7 form typically supply somewhere in the region of 90 to 180 mcg a day, and that amount doesn't change simply because you're over 50. Vitamin K2 helps calcium reach bones, which is why it often appears alongside vitamin D3.

Why there's no single "RDA" for K2

Nutrition reference figures were set for total vitamin K, largely based on its role in blood clotting, before the bone-related interest in the K2 form grew. So the numbers you'll see for K2 specifically — like the 90–180 mcg range for MK-7 — are widely-used general reference amounts from supplement practice, not a personal prescription or an official RDA. Treat them as a public reference point, not a target you must hit.

How K2 works with D3

The reason the two are so often paired: vitamin D3 helps your body take in calcium from food, and vitamin K2 helps calcium reach bones. They address different steps of the same story, which is why a formula built for women over 50 usually includes both rather than one alone. This is about complementary roles, not a treatment claim for any bone condition.

The one caution worth knowing: blood thinners

Vitamin K interacts with anticoagulant medicines of the warfarin type, because those drugs work by interfering with vitamin K. If you take a blood thinner, don't start or change a vitamin K2 supplement without talking to the doctor or pharmacist who manages your medication — consistency of intake matters for them, and this is a conversation to have before you buy, not after. K2 is fat-soluble, so taking it with a meal that contains some fat helps absorption.

Where Vyelle fits

Vyelle Daily Renewal provides 90 mcg of vitamin K2 as MK-7, disclosed on the label, paired with 2,000 IU of vitamin D3 so the calcium-absorption and calcium-to-bones steps are covered together. It's a once-daily drink taken with your morning routine. If you're on any anticoagulant, clear it with your prescriber first.
