Puritan's Pride is the mail-order, factory-direct, division of NBTY. Besides Puritan's Pride, NBTY also manufactures Nature's Bounty, Vitamin World, Rexall, Sundown, Solgar, and American Health products.
I have ordered from Puritan's Pride since the summer of 2000, when I started getting into health again after a rather unhealthy hiatus, in which I ballooned up to 200 pounds. I had ordered from Lee Nutrition and Nutrition Headquarters in the mid-1990s, but by 2000, both companies were out-of-business, so I went looking for an alternative source of inexpensive supplements. Since 2000, I have ordered from them probably 25-30 times, so this review of Puritan's Pride is based on quite a bit of experience. Some of the items I am familiar with include, B-Complex 50, Multi-Enzyme, and Fish Oil with Garlic.
Puritan's Pride guarantees their products, and when tested by independent labs, all of Nature's Bounty's products, including those of Puritan's Pride, perform very well. I feel very confident that Puritan's Pride products are high quality. I haven't had any quality problems with any of my Puritan's Pride products.
Puritan's Pride has a decent selection of products, most for great prices, although they seem to be slow to get some of the newer, cutting-edge products, and when they do, the price is often higher than their other products. I wish they offered more multi-vitamins without iron, and with lower levels of Vitamin A (both of these concerns reflect newer research about supplementing with Vitamin A and iron). In this regard, their products seem kind of old-fashioned. I am guessing most people with find what they need from Puritan's Pride. I wish they had Bromelain 2000 GDU product, but I can easily get that elsewhere. Puritan's Pride bought Doctor's Trust a few years ago, and unfortunately, did not continue DT's fine line of products.
Rarely does Puritan's Pride offer 70% off sales, or the 60-80% off sale (in which some items are 80% off, but not many). This means that the best regularly-offered deal is the "Buy 1, Get 2 free" special, which almost always runs every summer, and sometimes during other times of the year. Thus, I tend to stock-up from Puritan's Pride products in the summer.
Puritan's Pride does have several other sites, besides puritan.com, in which other sales sometimes run concurrently with the sale on puritan.com. These include puritansale.com, doctorstrust.com,vitamins.com, and puritancatalog.com. For awhile, puritansale offered 70%+ off many products, making it the best deal available, but unfortunately, most products on that site now are 50-60% off.
While I used to order almost all of my supplements from Puritan's Pride, they have raised their prices on many products recently, and stopped offering some of their best sales as often as in the past. For this reason, I don't always go to Puritan's Pride to order my supplements.
Usually the entire order is shipped out quickly, often arriving in a little less than a week. They always send out shipping notices via email, with tracking numbers. This makes keeping track of orders very easy. A few times I have had to wait for back-ordered items, but very rarely. Typically, the back-ordered items are shipped out within a 10 days.
Customer service is excellent and friendly. I have called them and emailed them in the past and they have always been helpful. I even emailed one of their representatives about the strength of their enzyme products (enzymes are measured by both activity and weight, and Puritan's Pride only lists enzyme weight on their products), and she kindly contacted their scientists to find out the information I needed.
I consider Puritan's Pride my primary supplement company, although this is changing to a degree as I have found other companies that offer better prices than Puritan's Pride. They offer high-quality products for a great price, and are well worth checking out if you think you are paying too much for your vitamins.
