Q. Does Flexicose® or FlexicosePlus® have any side effects?

Flexicose® and FlexicosePlus® are 100% gluten-free and are generally well tolerated as they are nutraceuticals, not pharmaceuticals. You should not take Flexicose® if you are allergic to shellfish.

If you are pregnant or nursing, always consult with your physician before starting any supplement. Always inform your doctor of any drug and/or supplement you are taking to prevent possible interactions.

Q. Do you source your chondroitin from bovine or shark cartilage?

We use chondroitin derived from bovine (cattle) cartilage because sharks are being slaughtered at an alarming rate and are considered close to extinction in many parts of the world.

At DTC Health, we have made a conscious decision not to contribute to this travesty. Instead, we use chondroitin derived from cattle, which is considered a highly renewable resource in our industrialized world. Cattle are already being raised and harvested with almost nothing wasted, providing a wide range of products and by-products for human use.

Q. What time of the day should I take Flexicose®?

Flexicose® can be taken at any time of the day that is convenient for you. It does not matter if you take Flexicose® before, during, or after meals. Many of our customers take Flexicose® in the morning with breakfast.

Q. What are the differences between the human and pet formulas?

Both versions of Flexicose® are identical. Likewise, both versions of FlexicosePlus® are identical. Pet Flexicose® and Pet FlexicosePlus® have different labels because of different dosage requirements based on weight.

Q. What are the differences between Flexicose® and FlexicosePlus®?

Both Flexicose® and FlexicosePlus® contain superior quality Glucosamine, Chondroitin and MSM, as well as other synergistic ingredients.

FlexicosePlus® was formulated for athletes and those interested in a more potent and natural formula. FlexicosePlus® contains all of the benefits of Flexicose® plus Hyaluronic Acid (HA), extra strength Chondroitin and MSM, with all-natural sweetener, flavor and color.

FlexicosePlus® is sweetened with Stevia only, making it safe for diabetics, hypoglycemics and those concerned with weight management.

Q. Why liquid glucosamine over tablets or pills?

Liquid glucosamine formulas, aside from being more readily bioavailable and easier to swallow, have another very important benefit. Unlike pills, liquid is absorbed as soon as it enters the stomach. It is not uncommon to have pills pass right through the body with the engraving marks still visible.

Pills and capsules may cost less, but in reality you get far less absorption for your money. Liquids are also easy to administer to pets because you can simply pour it over their food.

Q. What type of animals can I give Flexicose® to? Are there any other ailments besides arthritis that Flexicose® can help with?

Our customers have used Flexicose® successfully with common animals, such as dogs, cats and horses. We even have some pigs and other exotic pets as customers.

In addition to promoting arthritis pain relief, Flexicose® promotes improved joint mobility and flexibility. Flexicose® is also effective for knee, elbow and hip dysplasia, equine arthritis and osteochondrosis, to name a few.

* Do not feed to cattle or other ruminants.

**Also, not all ingredients in Flexicose® are recognized as essential nutrients by the AAFCOdog food nutrient profile.

Q. How long do I have to take Flexicose® for? Can I reduce the dosage over time?

Like a cut, your body does not heal itself instantly. Flexicose® should be taken at double the recommended dosage for the first two weeks to "jump start" cartilage repair and pain reduction. It is also safe to take double the dose of Flexicose® indefinitely, if needed.

If you are experiencing relief with your current dose, then there is little reason to cut back because the soothing ingredients in Flexicose® will continually keep your joints bathed in a protective fluid, and it will work to prevent further damage to your joints.

Because of stress and constant wear and tear to your joints, it is recommended that you continue to take Flexicose® to help prevent further deterioration.

Q. Is there a cure for Arthritis?

Arthritis is a painful, incurable condition with no known cure. If you or your pet struggle with joint pain, Flexicose® may still do wonders for you, and it may help ease your pain without the harmful effects of NSAIDs.

A recent landmark study, done by the National Institutes of Health (NIH), showed that the same kind of glucosamine found in Flexicose® was at least as effective as the NSAID, Celebrex, with far fewer side effects.

Q. Does Flexicose need to be refrigerated?

It is suggested that you refrigerate Flexicose® after opening. Prior to opening, Flexicose® can be stored at room temperature. Please be aware that there are preservatives in Flexicose® and FlexicosePlus® so you can take it with you on trips or vacations. You don't have to worry about it spoiling, unless the bottle is past its expiration date, which is on the bottom of every bottle. Please be advised that some settling will occur when taking FlexicosePlus®. Please shake well before each use.

What Our Customers Are Saying


I've been using Flexicose® for myself and my daughter and Pet Flexicose for my dog Toby (who has dysplasia and arthritis). My mobility has improved and my pain level has decreased exponentially! Toby now hops onto the furniture, he does not limp and he is able to go for moderate walks. My daughter is starting to feel some relief now, but her situation is so severe that it will take longer for her mobility to improve. But at least she can tell that her pain is starting to decrease.

Rich P.

I have extolled the virtues of Flexicose to numerous friends, relatives and acquaintances. My physical therapist spoke highly of Flexicose and, at his suggestion, I ordered my first supply. I have been very satisfied with the results.

Allison C.

I recently adopted a 10-year-old black lab mix. She was found on the side of the New England Thruway, presumably hit by a car, frail and in pain. Now that she is on Flexicose, I have weaned her off of the medication that the Vet prescribed and she is doing great. She doesn't shake, she runs, and she's loving life. Casey and I thank you very much!


I am a 47-year-old police officer with a knee injury acquired during 9/11. I was slowly losing the ability to play sports as I would be in too much pain for the next two days. Flexicose is magical! I have resumed my athletic schedule with a vengeance. I can now play whenever I feel like it, with only moderate soreness the same day. The next day I am back to normal. I literally feel like I'm in my late 20s again.

Tabatha W.

I have been buying Pet Flexicose for my dog Isabel for a little while now. I believe this order today is my fourth order. I am going to try the Pet FlexicosePlus this time for her. She is 2 years old and has hip dysplasia in both hips. She is rated a 4 out of 5 by my veterinarian. Hip replacement is not an option for her as she is so young that they are not sure how long it would last for her. My first time trying glucosamine I was a little skeptical and wanted to make sure I wasn't wasting money so I had ran out of glucosamine for about 2-3 weeks. At that point she starting limping and then not even putting any weight on her leg. Within 4 days of having the Pet Flexicose she wasn't limping anymore and seemed alot less stressed. The vet only had the pills which she hated and they ended up stuck in her teeth so she didn't get the full dosage. I tried the powder stuff from Costco. That was a fail! Thank you for providing this product and service. It is a pleasure to buy from you.

Dr. Dennis, Chiropractor

I am very pleased to report that I experienced immediate results using Flexicose. My stiffness and pain have been nearly eliminated and my mobility has greatly improved. I am also impressed with the innovative bottle design. Each dose is easily measured to drink directly from the bottle.

Ron from Canada

I noticed a significant reduction in pain in both my wrists and knees even before the two weeks of double dosing was over. At age 67, old injuries come back to haunt you and they don't go away easily. I found that out after trying many other products. Flexicose is the only supplement that really works for me! It is so very gratifying to know that I can continue my active life pain-free! My friends and family are going to hear a lot about Flexicose from me any time they mention joint pain. Thanks again and keep up the good work!


I cannot believe that Flexicose actually worked! I am 73 years old and have had severe back pain for 4 years. I literally could not walk with out two canes. After only three days of Flexicose, I am able to walk with no canes and I can easily get out of bed in the morning. That has been an almost impossible thing to do. Flexicose has brought me to life again. Thank you so much!

Carol R.

Our cat, Callie, is leading a normal life with many thanks to Flexicose. She was in horrible pain with arthritic hip joints and was looking at possible surgery and continued steroid shots. Callie responded to Flexicose so well that within 2 weeks she was almost back to her old self. Callie began bouncing around like "Riccochet Rabbit" and continues to do so. Many thanks for such a great supplement!!

Brenda C.

The pill form of glucosamine can pass through your body so quickly that you can still read the imprint on the pill. Yikes!! So I gave Flexicose® a try. Now my knees don't grind when I walk up stairs or ache like they used to in the morning. I will probably take Flexicose® for the rest of my life because of the alternative if I don't.

Tracy L.

My sister-in-law told me how much Flexicose® helped her dog. I didn't know what to expect, and didn't have high expectations, but wow! My dog is doing so much better. I honestly thought she might not have much time left. I can't believe how great she is doing.

Cindy C.

I have two plates, three rods, and fourteen screws in my spine. All titanium. I absolutely feel better physically taking Flexicose®. Thanks for a great product - one I feel confident recommending to my friends and family.


My ten year old pit bull no longer limps and is acting like a puppy again. He no longer gets sore after runs. You can definitely tell that he is happier and pain free. Honestly, you have extended the life of my pet, who is a huge part of my life. I have already recommended Flexicose® to others.

Andrew L

Ever since I began using Flexicose ®, I never had another flare up and my knees have felt great. There was about a 5 month period that I stopped using it and I started feeling soreness in my knees. So, I am convinced that Flexicose® works and I intend to keep using it.

Terrence, NYC

I am a 47-year-old police officer with a knee injury acquired during 9/11. I was slowly losing the ability to play sports as I would be in too much pain for the next two days. FlexicosePlus is magical! I have resumed my strenuous athletic schedule with a vengeance.

Trace H.

Having exhausted other options for years to manage my chronic shoulder pain, I tried FlexicosePlus and I am back to my regular workout schedule.

Julienne M.

I’ve been taking FlexicosePlus for over 2 years now and I wouldn’t be without it! If I forget to take it, my body reminds me.

Mike E.

Since taking FlexicosePlus, my right knee no longer “clicks” when I walk upstairs.

Richard P.

My knees were like barometers that did a better job of predicting the weather than the local weatherman. I began using FlexicosePlus at the suggestion of my physical therapist. The relief is nothing short of amazing!

Bryon B.

After approximately 4 weeks of use, FlexicosePlus has reduced the arthritic pain in my hip. I am now able to sleep through the night without awakening in pain.
