Reviews

D3-K2

"As someone who spends a lot of time working outdoors, I know vitamin D is important, but I never realized how important K2 is alongside it. NutraBio D3+K2 makes it simple by putting both together in one capsule. I appreciate that it uses plant-based D3 from lichen and MenaQ7 K2, and it contains no artificial colors, flavors, or sweeteners. The once-daily capsule is easy to add to my routine, and it gives me confidence that I’m supporting my bone health and overall wellness. For anyone looking for a high-quality vitamin D supplement with the added benefits of K2, this is an excellent option."

— JD S. (5/5)

Extremely Helpful

"This has helped me a lot in my cutting phase. It has helped me sleep better but I also feel like it has kept my immune system good. In terms of my cutting phase I feel like it has helped lose some stubborn fat. One good plus is I had blood exams a month after taking this and my vit d results were much better than before I started taking them."

A very high quality VD3/K2

"A very high quality VD3/K2 stack! You cannot go wrong with this. Very important to take together. Some say that 10,000 ius of vitamin d3 is the bare minimum to take daily. Taking 15,000 20,000 all the way up to 30,000 ius daily can do absolute wonders for your health across the board."

Q&A

Frequently Asked Questions

What is vitamin D3 and K2 good for?

Vitamin D3 and K2 work together to support bone health and immune function. Vitamin D3 helps your body absorb calcium, and vitamin K2 helps direct that calcium toward your bones. Taken as a pair, they support the strong, resilient foundation your body relies on every day. NutraBio D3+K2 delivers both in a single daily capsule, with 5,000 IU of vitamin D3 and 180 mcg of K2 as MenaQ7.

Why should you take vitamin D3 and K2 together?

You should take vitamin D3 and K2 together because they support each other. Vitamin D3 increases how much calcium your body takes in, while vitamin K2 helps guide that calcium to your bones, where you want it. On their own, each does important work, but together they help your daily routine deliver the bone and immune support you are really after.

When is the best time to take vitamin D3 and K2?

The best time to take vitamin D3 and K2 is with a meal that contains some fat, since both vitamins are fat soluble and absorb better alongside dietary fat. The exact time of day matters less than consistency, so take it whenever you are most likely to remember it. Many people pair it with breakfast or their largest meal of the day.

How much vitamin D3 and K2 is in NutraBio D3+K2?

Each capsule of NutraBio D3+K2 provides 5,000 IU (125 mcg) of vitamin D3 and 180 mcg of vitamin K2 as MenaQ7. That is 625% of the Daily Value for vitamin D and 150% of the Daily Value for vitamin K. One bottle contains 60 servings, a full two month supply at one capsule a day.

Is the vitamin D3 in NutraBio D3+K2 plant based?

Yes, the vitamin D3 in NutraBio D3+K2 is plant based, sourced from lichen rather than animal sources. It comes in a vegetarian capsule and is made without artificial colors, flavors, or sweeteners, which makes it a clean option for those who prefer plant sourced supplements.

What is the best form of vitamin K2?

Vitamin K2 as MK-7 is widely considered the preferred form because it stays active in the body longer than other forms, which makes it well suited to once daily supplements. NutraBio D3+K2 uses MenaQ7, a trusted, naturally sourced MK-7.

Can you take vitamin D3 and K2 every day?

Yes, vitamin D3 and K2 is designed to be taken every day as part of your routine. Take one capsule daily, preferably with food. As with any supplement, talk to your healthcare provider before starting, especially if you take medication or have a medical condition.

Who should not take vitamin K2?

If you take blood thinning medication such as warfarin or heparin, you should speak with your doctor before taking any product with vitamin K2, since vitamin K can interact with these medications. This product is also not for use by individuals under 18, or those who are pregnant or nursing, without medical guidance. Always consult a physician if you have a medical condition or take any medication.
