Rating: 4.5 (out of 5)

UPDATED: December 21st, 2023

Welcome to this review of the Douglas Labs Ultra Preventive X multivitamin product. Douglas Laboratories is a well regarded supplement company that is based in Pittsburgh, Pennsylvania, USA. It also has business operations in Canada, Germany, Spain, and Japan.

They are widely respected by many in the supplement business as well as in the Western medicine medical establishment. For a time, you could only get Douglas Laboratories products if they were recommended or referred by a medical doctor. Not many supplement manufacturers can say that.

Their success has led to multiple offerings. Moreover, they are now one of the most prolific supplement companies in the world as well, offering a full gambit of supplements including weight reduction, detoxification, vitamin and minerals, medicinal herbs, omega 3, enzyme formulas, bodybuilding, and esoteric specialty supplements as well.

They claim that all of their products are produced by research and careful manufacturing processes. Indeed, all of their products are produced in cGMP-compliant facilities that meet the U.S PhUltra Preventive Xarmacopeia standards. This is impressive for a supplement company as they make their products according to the same standards that pharmaceutical drugs must adhere to in the U.S. This ensures the highest quality product possible and should be mentioned.

They have also won many awards including the Nutrisearch Gold Medal of Achievement for many of its nutritional supplement products.

The company says all its “products are sold exclusively to licensed healthcare professionals” (para. 1), but that is not true — you can buy it through Amazon and bypass it that way. (Source:

What Are Douglas Labs Ultra Preventive X Supplement’s Ingredients?

The product is made utilizing an herbal green food base and has 51 ingredients exclusive of binding agents. That 51 list includes vegetable extracts, trace elements, minerals and vitamins. The product is also magnesium stearate free, which is notable. The green food base, the company says, has important phytonutrients as well. These gluten-free grasses and microalgae help “supply chlorphyll, carotenes, B-vitamins, and trace elements.”

In addition, the product is ostensibly developed by Douglas Labs to be in precise balance to optimize bio-availability without toxic buildup within the system. They’ve been very successful and that may be the most powerful point in their sales and marketing efforts.

Best Multi-Vitamins in The Market, by A.M., October 2, 2011.
“I love this brand because of their superior quality and use of natural vitamins rather than synthetic ones. I have been taking it for some times and my energy level and overall health improved. I suggest to start with half the recommended dosage if you are new to the brand. Read the NutriSearch Comparative Guide to Nutritional Supplements for the tests on this supplement rated as one of the best.”

One of The Best Multivitamins Around. Amazon Verified Purchase, Ernesto Chavez, April 4, 2012.
“This product is made by Douglas Labs. The same company that manufactures the Mercola brand of whole food vitamins. This too is a whole food based formula. This one is a different formula and more potent though. I didn’t feel the niacin rush that some have claimed. I train brazilian jiu jitsu and it’s a very demanding martial art/sport. These help me get a complete array of vitamins, minerals and some enzymes, greens and phytonutrients. Highly recommended.”

How Much Is The Douglas Labs Ultra Preventive X Multivitamin?

One bottle goes for $52.30 to $64.50 on Amazon. At Douglas Laboratories website, it sells for $68.50. The absolute and cheapest price I’ve been able to find is on Amazon.

Does Ultra Preventive X Come With a Product Guarantee?

Yes, it does. Douglas Laboratories offers a guarantee, but it’s not the greatest guarantee around, which is somewhat disappointing.  Here are the particulars. If you buy from Amazon, they say, “Items shipped from sellers other than are subject to the Product Return Policies unless otherwise stated in their Return Policy. They may not accept returns past the normal return window established in their Return Policy.” You can read that in its entirety here:

However, there is another element to the guarantee. Currently, Douglas Laboratories’ policy is that the buyer has 48 hours to initiate a return. In my opinion, that is a very small window to determine if the product works or not and is for you, but that is their guarantee.

I think this is one thing they could improve as they have a superb product with their Ultra Preventive X multivitamin.

Any Customer Complaints or Product Problems?

This multivitamin product is very well received and is one of the most popular in the world. In the United States, it is one of the most popular with doctors as well as health seekers. In fact, many medical doctors recommend it to their patients.

The product is not without its faults, though. As mentioned in the previous section, its guarantee is limited to a 48-hour decision window. In other words, if you decide you don’t want the product, you have to send it back before the 48-hour mark elapses.

Another element that is problematic is that the product has as one of its binding agents or “excipients” is silica. Silica is basically sand. Granted it’s in a small amount, but it is notable to mention. The company says the amount is negligible and they are probably right.

The usage of silica is commonplace in the vitamin supplement world, but some don’t use it at all opting instead for other excipient ingredients.

What About Product Shipping Costs?

If you order from Douglas Laboratories directly, their policy is for orders under $300 USD, add $10.00 for shipping and handling. Free shipping applies to all Douglas Labs labeled product and Douglas custom labeled product orders only. All orders outside of their 1-2 day UPS delivery zone ship by UPS 2-3 day will receive it at no additional charge. Next day shipping is available but it is an extra cost as well.

Where Can I Get More Information About Douglas Laboratories Ultra Preventive X Multivitamin?

You can learn more about it here. You can also download Douglas Laboratories free datasheet on the product here. (Again, you will Adobe Reader to read it as it’s a .pdf file. You can get Adobe Reader for free here if you don’t already have it.)

Douglas Labs Ultra Preventive XWhere Can I Buy It?

You can buy this product directly from Douglas Laboratories but it’s cheaper to buy it from Amazon. But you are free to choose.

There, you’ll be given many different resellers who sell it cheaper than Douglas Laboratories does. Plus, you’re still protected by their guarantee.

In conclusion,  yes, this is a high-quality, pharmaceutical-grade multivitamin and is one of the very best ones in the world. I hope this Douglas Labs Ultra Preventive X review has been useful to you.
