Choosing the Best Vitamin D Supplement for Sleep

Best Vitamin D Supplement for Sleep

MOST OF US HAVE FROWN UP HEARING how important vitamin D to growing bones, good health, and in preventing osteoporosis.

The problem is that many of us end being deficient in this crucial nutrient.

Why? Because we spend far too much time out of the sun and then when we are out in the sun, we all lather ourselves up with sunscreen.

No sunlight hitting your body means that it cannot produce enough vitamin D to meet your daily requirements. Which then leads to the need for the best vitamin D supplement you can find to help make up the deficit.

How Much Vitamin D Should I Take?

Bear in mind that all figures are based on 50% of the sample group and that your needs can vary significantly, the National Institutes of Health, you need:

As you can see from, practically from birth, it is possible to need a vitamin D supplement. You can also see that from 1 year of age all the way to 70 years of age, the amount required is the same. It only changes at 70 due to the increased risk of bone loss and osteoporosis.

Which is Better a Vitamin D2 or Vitamin D3 Supplement?

While browsing through the different vitamin D supplements on the market, you will find both vitamin D2 and vitamin D3 supplements. Which leads to the obvious question, ” Which is the best vitamin D supplement?”

  • Vitamin D2 comes from plants.
  • Vitamin D3 is the type your body produces when exposed to sunlight.
  • Vitamin D3 supplements are produced from sheep's wool (making them okay for vegetarians but not for vegans).

According to a study reported in the American Journal of Clinical Nutrition, vitamin D3 supplements are significantly more effective at raising the level of vitamin D stored in your body that vitamin D2. Thus, if you prefer to take D2 or are vegan, you would need to take a much larger dose than you would of D3 to achieve the same benefits.

What Does Vitamin D Actually Do in My Body?

Your body uses vitamin D to help it absorb calcium from the foods you eat and to regulate your calcium levels to ensure you don't have too much or too little.

Your body uses calcium to help your bones grow, repair themselves, and keep them good and strong. When your body doesn't have enough calcium, your bones can weaken and become brittle.

How Do I Find Out if I Need a Calcium/Vitamin D Supplement?

There is nothing wrong with wanting to find out if you are vitamin D deficient before you decide to start taking a supplement. There are three ways you can find out what your vitamin D levels are at:

  • Your Doctor – ask your doctor to perform a 25(OH)D blood test. While there is another test, the 1,25(OH)D, but it won't tell where your vitamin D levels are at.
  • In-Home Test – you can order a home test kit online, have it delivered to your home, and do it yourself. It’s a little like the blood sugar tests diabetics do; you prick your finger place a drop of your blood on the blotting paper that comes in the kit, and mail back for testing. You receive the results of your test in the mail.
  • Online Testing – no, this doesn't mean quite what it sounds like. Here you place your order for an in-home testing kit and take it to your nearest lab for testing. These kits cost a bit more, but you may be able to get your results a little faster.

What Happens if I Take Too Much Vitamin D?

While your chances of getting too much vitamin D from food, it is quite possible to overdose yourself on even the best vitamin D supplements. Known as vitamin D toxicity, too much D can lead to hypercalcemia or an excessive amount of calcium in your body. This condition can cause damage to your veins and organs.

The good news is that you cannot get vitamin D toxicity from spending too much time out in the sun. Your body controls how much vitamin D it produces to ensure this condition cannot occur unless you overdo the supplements.

What Happens if I Get Too Little Vitamin D?

If your body is not getting enough vitamin D, then it can't absorb the amount of calcium it needs. This can lead to rickets in children and rickets or osteomalacia in seniors.

Rickets can lead to soft bones that lead to skeletal deformities. Caught early enough in children, it is possible to reverse the damage by giving the child a very high dose of vitamin D. It works in kids because their bones are still growing and able to absorb the extra calcium, helping to re-mineralize their bones.

Essential Things to Know When Looking for the Best Vitamin D Supplement

With so many vitamin D supplements on the market, there are a few things you should look for as you search for the right one for your needs.

Reputable Third-Party Testing

As you may or may not know, the Food and Drug Administration (FDA) regulates every food product sold in this country. However, they offer no oversight or regulatory control whatsoever over dietary supplements. This means, you never know if what the label on a particular product matches what's actually in it.

It is possible for supplements to contain contaminants such as lead. According to independent testing company Labdoor, some supplements they tested contained as much as 900 percent more vitamin D than listed. Any supplement (not just vitamin D) you buy should state they have been tested by one of these three independent and highly reputable laboratories:

  • National Sanitation Foundation (NSF) – The NSF is an independent testing facility that sets the standards for consumer product safety around the world.
  • United States Pharmacopeial Convention (USP) – The USP is a not-for-profit scientific organization that sets the standards regarding both quality and purity in the U.S. and over 140 other countries for food supplements and medicines.
  • Labdoor – a no-cost consumer protection organization that tests dietary supplements for accuracy, purity, and value.

If the supplements you are looking at do not display the symbols or state they have been inspected by one of the above organizations, you should pass them on.

Keep the Additives to a Minimum

While it is impossible for you to buy a supplement that contains nothing but vitamin D, you can buy one with a minimal amount of artificial ingredients and no sugar. The reason you can't buy a straight vitamin D supplement is that the recommended dosage is so tiny physically that it is impossible to pick up.

This tiny amount has to be mixed with other ingredients just to create a supplement big enough for a person to see and take. We also believe the best vitamin D supplements are those that contain only vitamin D with no other supplements. Keep in mind that just about all of us need a vitamin D supplement, but only a few of us need extra calcium or CoQ10.

Vitamin D Likes Fatty Oil

Like many other vitamins, vitamin D dissolves more easily in fat than it does in water. Your body is better able to absorb vitamin D when you take it with fatty foods, which is why so many supplements contain some for oil.

If you choose a supplement that does not include any form of oil, you should take it with a small amount of added fat such asis avocado, meat, a salad dressing, or a slice of your favorite cheese.

Spending more time out in the sun letting your body naturally synthesize vitamin D and choosing the right foods. You can try spending 10 to 15 minutes every day out in the sun, but not all of us can find even this small amount of time to relax out in the sun.

Final Thoughts

While testing may reveal you need more vitamin D, be sure you talk to your doctor before taking any type of supplement and have your blood frequently tested to ensure your vitamin D levels are neither too low or too high as both can be bad for your health.

Keep in mind that not all supplements work the same way for everyone. You may need to try several before you find the best vitamin D supplement for you.
