Why we're Not Able To Get Enough Vitamin D Every Day

Few foods are naturally rich in vitamin D. Fish like salmon, tuna, and mackerel top the list.  And while other foods like milk, cereal and juices are fortified with vitamin D, it's usually a scant amount — and usually in the wrong form.

Our body makes vitamin D when our skin is exposed to the sun. Sunscreen creates a barrier between our skin and the sun — preventing our body from making Vitamin D.

So what should we do?
Take supplement:
The natural form, vitamin D3, is at least three times more potent than vitamin D2.  Plus, D3 is more easily used by your body.
The RDA for Vitamin D is only 400 IU.  That was the amount recommended 50 years ago, before modern research studies were done.

These studies show that the optimum amount to take is 5,000-10,000 IU a day — dozens of times the amount of the RDA!  That's the amount you need to protect your immune system, your heart, your joints, and your eyes. 

It's also the amount you would get from being exposed to 15-20 minutes of sunshine in the middle of the day. Which means it's perfectly safe. In fact, studies show that you'd have to take 40,000-100,000 IU  a day for several months before you experienced any negative effects. 

How To Quickly Boost Your Vitamin D Levels

Fortunately, the folks at Advanced Bionutritionals have a Vitamin D3 product that meets my approval. Here's why I recommend it:

Taken together, this powerful blend of helpful bacteria: 

1. Each tablet from their Vitamin D3 contains 5,000 IU. So you can get a full day's worth in just a small pill or two.  
2. Their D3 is 100% naturally sourced. It comes from lanolin found in sheep's wool. Therefore, you're getting the natural, more potent D3 instead of the weaker D2.   
3. Each batch is tested for effective absorption. In fact, their tablet dissolves within 45 minutes of you taking it. So it doesn't pass through your body unabsorbed.  
4. Their manufacturing process conforms with or exceeds the standards set by the US government, the Medicine Control Agency of Europe, the U.S. Pharmacopeia, and the state of California.   
5. Their Vitamin D3 is lab-tested by independent third-party laboratories. So you know each batch is consistent and made to the same high standard.

As you consider all these reasons, you can see why I recommend Advanced Bionutritionals above other manufacturers. And to get you to try their vitamin D, they're making the following generous
