Frequently Asked Questions

A lot of people are interested in vitamin D3 and K2, but they don't know where to start when it comes to learning more about these nutrients.

It can be hard to figure out the best vitamin D3 and K2 supplements you should be taking, and even harder to determine if they're working for you.

We've put together a list of the most frequently asked questions so that you can learn more about these important nutrients.

What is Vitamin D3 and K2 good for?

Vitamin D3 and K2 are both essential nutrients for overall health.

It is important for calcium absorption and maintaining strong bones, while vitamin K2 helps to protect against heart disease and encourages healthy blood circulation.

Additionally, vitamin D3 K2 work together to promote a healthy immune system and help keep cells functioning properly.

When is the best time to take vitamin D3?

There is some debate over when the best time to take this supplement, but most agree that it is best to take them in the morning.

The reason for this is that it can slightly raise your body temperature, and taking them in the morning gives your body time to adjust to the higher temperature before bedtime. Taking them at night may disrupt your sleep patterns.

What is the best vitamin D3 to take?

Take one that provides you with the recommended daily allowance (RDA) of 400-800 IU.

Can I take vitamin D3 and K2 every day?

Yes, you can take this supplement every day. In fact, many experts recommend doing so in order to maintain optimal health.

Vitamin D3 is essential for calcium absorption and healthy bones, while K2 helps to keep calcium in the bones and out of the arteries. Taking both vitamins together ensures that your body gets the nutrients it needs for optimal bone health.

Who needs vitamin D3?

According to the NIH, anyone who doesn't get enough exposure to sunlight needs to supplement vitamin d.

How much vitamin D3 should I take a day?

The amount you should take each day depends on several factors, including your age, health status, and sun exposure.

The Institute of Medicine (IOM) recommends a daily intake of 600 IU (international units) for adults aged 19-70 and 800 IU for adults over 70. 

However, some experts feel that these recommendations are too low and that most people need more than the IOM recommends.

The best way to determine how much you need is to have your blood tested for 25-OH levels.

This testing can be done through a standard blood test at your doctor's office. Your 25-OH level will indicate whether or not you are deficient and how much you need to supplement.

A level of 30 ng/ml or higher is considered sufficient, while levels below 20 ng/ml indicate a deficiency. If your levels are below 30 ng/ml, you may want to consider taking a supplement.

What happens when you start taking vitamin D3?

Several things happen when you start taking it.

  • Your body begins to absorb calcium more effectively.
  • You may experience improved bone density.
  • Your immune system may become stronger.
  • You may have a reduced risk of developing cancer.
  • You may see an overall improvement in your health.

What are the symptoms of a vitamin D deficiency?

There are a number of symptoms that can indicate that you may have a deficiency.

These can include fatigue, muscle weakness, bone pain, and an increased risk of infections. Many people with low levels also report feeling depression and anxiety.

If you think you may have low levels, it's important to talk to your doctor to get a blood test to confirm. Treatments for low levels typically involve getting more exposure to sunlight or taking a supplement.

What is the difference between vitamin D and vitamin D3?

They are both forms of Vitamin D. However, vitamin D3 is the more bioactive form of the vitamin. This means that it is more readily absorbed and used by the body.

Additionally, many over-the-counter multivitamins contain the form of vitamin D2. While this form is also a valid source of the vitamin, it is not as bioavailable as vitamin D3.

Can vitamin D affect blood pressure?

Yes, it can have an effect on blood pressure. There is some evidence to suggest a deficiency can lead to high blood pressure and supplements can help lower blood pressure in people who are deficient in.

However, more research is needed to confirm these effects and it is not clear whether everyone would benefit from taking this supplement for hypertension.

What foods contain vitamin D?

There are a few different food sources, although the best way to get this nutrient is through exposure to sunlight.

Foods that contain this vitamin include fatty fish like salmon and tuna, egg yolks, and fortified foods like milk, orange juice, and cereals.

Some mushrooms also contain some. It's important to note that our bodies can also generate this nutrient on their own when we're exposed to sunlight.
