Nature Made Vitamin D Review – USP Outweigh Harmful?

In this Nature Made Vitamin D Review, we will investigate the supplement in its entirety.

Or in other words, we will assess the supplement as a whole by looking at its vitamin D form, analyze how effective it is, we’ll check the amounts of the vitamin, as well as explore information on the additives it applies.

The goal here as always is for you to not need to look and waste time in looking at any other reviews for this supplement. Therefore, if there is a section I haven’t covered but you’re interested in, let me know. And I’ll add that to the review.

Nature Made Vitamin D Review – Overview

On the description page (sale’s page) of the Nature Made Vitamin D you won’t find a whole lot about it. Although there’s seemingly a lot of text there, it’s all quite general.

Nature Made Vitamin D Review

Vitamin D3 is the better form of vitamin D, Vitamin D helps support bone, teeth, muscle, and immune health, vitamin D levels have been shown to play an important role in any persons overall health, the supplement is of a high standard, made from carefully selected ingredients under strict manufacturing processes. All the general stuff.

However, there is this one claim that stands out from all else.

Nature Made Vitamin D is the #1 Pharmacist Recommended Vitamin and Supplement Brand.

Which I do see as an extremely bold claim.

Quality wise the supplement is USP (United States Pharmacopeia) certified (which by the way is amazing). I’m jumping ahead of time here, however, just know that this guarantees that all of the ingredients in it are of high quality and you’re not getting some low quality, incidental substances full supplement.

As of writing this article Nature Made Vitamin D is also the #4 on Amazon’s bestseller list.

Surely, it accounts for something… Or does it?

The Vitamin D Form Truly Is The Superior One

I believe it’s been long enough discussed now.

Many studies are out. And all health specialists seem to unanimously agree that the natural form of vitamin D – the vitamin D3 – is the superior form of vitamin D [R, R, R, R, R, R, R, R].

Nature Made Vitamin D employs that same vitamin D form that our skin manifests when exposed to sunlight

It is also the same form our skin manufacturer through the exposure of sunlight. Thus, the form of vitamin D2 has been doomed to oblivion [R, R, R, R, R, R, R, R].

The sad thing is, however, that not all supplements actually use the vitamin D3 form. And why would they if they don’t truly care for their customer’s health – vitamin D2 is the much cheaper form to produce.

In this regard, Nature Made Vitamin D does not sin.

The supplement contains the vitamin D3 form (Cholecalciferol). It does not, however, specify of what source it is made.

While it might not be as important for people generally, for certain groups of people like Vegans it can make a difference.

Vitamin D Amounts Are All Good

There are various opinions on what should be the recommended intake of vitamin D through supplements daily.

Many recommend at least 2000 IU. Others say that you should go with what you have in your multivitamin, plus an additional 2000 IU from a singular supplement. Whereas in the case of a deficiency it should be considerably higher.

In Regards To The Vitamin D Amounts It's All Good

Although the particular version of the supplement that we are looking at is the 5000 IU version, there are, however, other choices as well.

They also offer 1000 IU and 2000 IU. Thus no matter your vitamin D needs, you will be able to find or innovate the dose you need depending on your individual circumstances.

There Are Some Red Flags In Additives

Nature Made Vitamin D has quite a number of additives. Although this is not necessarily bad, it does, however, largely depend on the ones used. In the case of this supplement – by no means, it does look amazing, at the same time, it’s not all bad.

Soybean Oil – One of The Additives in Nature Made Vitamin D

So, the supplement employs 5 different additives – Soybean Oil, Gelatin, Glycerin, Water, Corn Oil.

Water can be disregarded as not being of an issue. So can also be Gelatin and Glycerin. All of these are completely fine to have in your supplement and they shouldn’t raise any concerns [R, R, R, R, R, R, R, R, R, R, R].

It is, on the other hand, much different for Soybean Oil and Corn Oil.

To say the least, these are oils very far from the ideal ones to use in such a supplement. They’re cheap and for certain groups of people may raise various health concerns.

Corn Oil – Another Additive In The Supplement

For example, Soybean Oil promotes chronic inflammation, which is the root cause of virtually all chronic diseases. Soybean oil can also cause infertility, cancer, mineral deficiencies, block protein digestion, and has other unpleasant side effects [R, R, R, R, R].

All in all, though, it’s a controversial ingredient as there are benefits associated with the use of it [R, R].

On that same note Corn Oil is also a controversial one. There are some benefits to its name. However, with the amounts of modern consumption, it is more likely to be of negative health effects such as cancer, liver-toxicity,  chronic inflammation, obesity, heart disease as well as other adverse effects [R, R, R, R, R].

Thus, it would be much, much better if these oils wouldn’t be a part of this supplement. There are so many healthy options in this regard that could work as a better substitute.

A Somewhat Minor Concern… OR NOT?

Nature Made Vitamin D claims to be a supplement without any added colors, artificial flavors, preservatives, yeast, starch or even gluten, as well as being USP verified, of course. But what about GMOs?

Genetically Modified Organisms within the two substances – Soybean Oil and Corn Oil – are known to have even more hazardous effects than those that we discussed earlier. Furthermore, 90% of the time these two substances are of this source [R, R, R, R, R, R, R, R].

Both Soybean Oil And Corn Oil Are Of GMO

Thus, I would say that the claim of GMO-free is even more important than many of the quality claims displayed for the supplement.

So, is it of GMOs?


I believe, yes.

And this is for two reasons.

First, if the manufacturer considers it to be important enough to identify and declare on the label the quality claims that it has (no added colors, artificial flavors, etc.), in truth, there is no reason why it shouldn’t have had the GMO-free notification if it was the case.

Thus, I seriously doubt that they have just by accident forgot to add that assertion to the list. Because if it were true (the supplement being of GMO-free), that would only benefit their product in the eyes on the customer.

Which, without doubt, they would be interested in taking advantage of, because it might guarantee them more sales.

Second, the fact that the supplement is USP verified does not imply that it is GMO-free. Meaning, the verification does imply quite a few things about the ingredient quality and purity but none of them is related to being without GMOs.

Thus, it’s safe to say that Nature Made Vitamin D contains GMO material. Which, especially in regards to the two ingredients at hand – Corn Oil and Soybean Oil – I do not see as something that is compatible with amazing health [R, R, R, R, R, R, R].

Final Thoughts On Nature Made Vitamin D

The Nature Made Vitamin D contains the best form of vitamin D possible for consumption. It is also of sufficient amounts. Furthermore, it offers also a variety of dosing options, which can be easily adjusted to your own individual needs.

Nature Made Vitamin D Is Not Great Choice For Vitamin D Supplementation – Avoid It

On that same note, however, it is safe to say that both the Corn Oil and Soybean are of GMO material, which essentially promises to undermine your health in a seriously negative way. Thus, should preferably be avoided.

In that regard, needless to say, if you’re on the lookout for a great vitamin D supplement Nature Made Vitamin D shouldn’t be your choice.

Instead what you could go for, is something that is my vitamin D supplement of choice.

Other than that, I hope the article helped you find the information you were looking for, but if not – definitely let me know in the comments on how I could further improve it.

If you have a tiny bit of time, I would highly appreciate even one line in the comments. That helps a ton and will be highly appreciated.

Hope to see you in another article!

Cheers, Stay Healthy & Have a Great One!

  1. I have heard a lot about nature made vitamin D supplements. And this particular information about it was a plus to what I’ve already heard. Namely, the fact that it contains solid ingredients at the right proportion. Also, knew about the United States Pharmacopeia certification. What I didn’t know about though was that it probably contains GMOs. And I’m not a fan of those.

    Thanks for sharing and letting us know that people should probably steer clear of this one.

    1. Hey, Abiodun!

      I’m glad the article was helpful and you were able to find some valuable insights!
      Totally made my day!

      Cheers, and have a Great One, Abiodun!

  2. What a remarkably detailed review of Nature Made Vitamin D.

    I didn’t understand the difference between Vitamin D2 and D3 until I read your article. This was making the product look good, along with the fact that the supplement is USP (United States Pharmacopeia) certified. In all…

    It was looking so good until we got to the Genetically Modified stuff.

    I was astounded to discover that the product contained five additives Soybean Oil, Gelatin, Glycerin, Water, Corn Oil.

    Clearly, no issues with water, but Soy Bean and Corn Oil. Probably GMO.

    To me , that’s a big turn-off. So thank you for all this information.

    I’ll be taking a close look at your recommended product. Or spending more time in the sun!

    1. Hey, Phil!

      I truly appreciate the kind words! Totally made my day! 🙂

  3. I love this truly deep dive into a single supplement.  You don’t see that very often. I particularly like the fact that you address the additives.  I’ve started paying attention to that myself, those “other ingredients” listed beneath the main nutrition panel. 

    I do take a vitamin D supplement, the D3 form, but you’ve given me some new things to think about which will help with some of my own reviews.  

    Thanks, I expect to be back for more. 

    1. Hey, Jon!

      I’m really glad you enjoyed the article. Means a lot. 🙂

  4. I actually not heard of this company before, as well as of the one you suggested at the end of this post. I am happy that you did explain some of the pros and cons of this vitamin in your review. I know very little about what goes into supplements, well didn’t know until I read this post. Thank you for letting me become more aware of some of the ingredients to avoid.

    1. Hey, Sam!

      I’m delighted you enjoyed the article!
      And I’m glad you picked up a thing or two. 🙂

      Cheers, and Have a Great One!

  5. Can you have too much Vitamin D? I didn’t even know there were different types of Vitamin D – and no surprise that some supplement manufacturers go for the cheaper option. Also, good points made about whether the supplement contains GMO products or not. A lesson to us all to double-check what we’re actually taking. A useful article indeed.

    1. Hey, Rob!

      I’m really glad you found the article useful!
      That lesson of double-checking is a very good lesson indeed.

      Can you have too much? Well, in theory, definitely, but I haven’t really heard of anyone these days overdosing on that stuff. Much to the contrary, in the modern day environment, many people are, in fact, deficient in vitamin D. What’s worse, estimates show that most don’t even know they’re deficient.

      I hope that answers the question.

      Cheers, and have a Great One, Rob!

  6. TO Be Honest, I’ve never heard about vitamin D3 before. Truly, readers are leaders. I need to take into cognizance of my health because this article is just for junk eaters like me that doesn’t care about what goes into their mouth.

    How can I use this supplement for Hormone Deficiency? Soya beans causes inflammation, Infertility, and cancer? Omg!!! I’m crying my ass out right here because Soya bean is what I’ve almost been taking almost all my life. I’m really scared because I can’t remember the last time I’ve gone for medical checkup!!

    1. Hey, Kehinde!

      There is no need to panic, my friend. Soybeans and Soybean Oil are two distinct products and therefore have also different properties.
      While Soybeans as such of GMOs are probably much worse than organically grown ones, as far as I know, they are not associated with the kind of health risks that the Soybean Oil is.

      I hope that calms your mind.

      Cheers, and have a Great One!
