A Guide to Glucosamine Products for Pets

Glucosamine is very beneficial in the treatment of arthritis and hip dysplasia in pets and is backed by numerous double-blind, placebo-controlled studies. In these studies, glucosamine has been shown to rehabilitate cartilage and reduce the progression of arthritis, significantly lessen pain from arthritis, and increase mobility in dogs and cats. However, one glucosamine product can be very different from another.

When your pet's pain relief and health is at stake, you need to know how to choose between competing products and see through the marketing hype. There are six factors that you need to take into your decision before purchasing any glucosamine product. These are:

  • Amount of glucosamine per daily dose
  • Type of Glucosamine
  • Quality of Ingredients
  • Delivery System
  • Synergistic Ingredients
  • Price Per Day

  • It is very important to compare price per day and not price per product, as many companies try to fool you by providing 60 capsules or 32 oz. and not telling you until after you purchased that you must use 6 capsules or 2 oz. per day. Be careful to always compare price per day.

Did you know that the absorption rate and bio-availability of the glucosamine in pills is significantly less than that when glucosamine is delivered in liquid form? The "claimed fact" that pills are the only and best way to obtain glucosamine is simply not true.

Glucosamine provided in liquid form is absorbed more quickly, much more fully, and provides greater and longer lasting relief.



First we will review the leading liquid glucosamine products...

A note on MSM: There is growing evidence that this substance is of value. Consumerlabs.com has been quoted as saying "MSM supplements...are used primarily for reducing the pain associated with osteoarthritis — although there is little research to show that it is effective." http://www.consumerlab.com/news/news_060401.asp . Some MSM containing products may be contaminated with DMSO, a substance that should not be taken orally. Currently the FDA nor any federal or state agency routinely test MSM. The Dimethyl sulfoxide (DMSO) is an industrial compound that has been touted as a relief for inflamed joints. While it may give temporary relief, it is unproven and may cause skin irritation and diarrhea. Interestingly, the claim to fame for MSM is that it supplies the body with extra sulfur. Glucosamine Sulfate and Chondroitin Sulfate products contain plenty of available sulfur.

The Capsule Products

Reminder: Glucosamine provided in liquid form is absorbed more quickly, much more fully, and provides greater and longer lasting relief.

  Arthrix

Arthrix™

Amount of Glucosamine per daily dose for
10 pound pet:
150 mg
30 pound pet: 300 mg
75 pound pet:
600 mg
125 pound pet: 850 mg

Type of Glucosamine: Glucosamine HCL

Quality of Glucosamine: not stated

Delivery System: capsule pill

Synergistic Ingredients: MSM, ester-c, arthrix, trace of Omega 3

Price per day for 10 pound pet: $0.47
Price per day for 30 pound pet: $0.93
Price per day for 75 pound pet: $1.40
Price per day for 125 pound pet: $2.33

Rating Rationale: Arthrix is a fairly expensive capsule product. With the glucosamine in powder form delivered in a capsule, the glucosamine will not be fully absorbed and it may take 6-10 weeks to notice relief if any at all occurs. This product lacks a number of nutritional ingredients that are essential to a well-balanced, fully effective treatment for arthritis in dogs and cats. Furthermore, the glucosamine used in Glucosamine HCL, a less expensive and not as fully studied as Glucosamine Sulfate. Also, the dosage of glucosamine is less than optimal. A 125 pound pet should be receiving about 1250 mg, not 850 mg, for example.

  Cosequin DS™


Cosequin DS™


Amount of Glucosamine per daily dose for
10 pound pet:
125 mg
30 pound pet: 500 mg
75 pound pet:
750 mg
125 pound pet: 1000 mg

Type of Glucosamine: Glucosamine HCL

Quality of Glucosamine: "high purity"

Delivery System: capsule tablets

Synergistic Ingredients: Manganese, Chondroitin

Price per day for 30 pound pet: $0.77
Price per day for 75 pound pet: $1.17
Price per day for 125 pound pet: $1.55

Rating Rationale: A good amount of glucosamine, however, it is all glucosamine HCL. Furthermore, in pill form, the glucosamine HCL and chondroitin sulfate will not be absorbed very well and provide less than optimal treatment for your pet's arthritis.

Manufacturer: Nutramax Laboratories, Inc.

Summary

In summary, we recommend products that contain 98% purity or higher, high quality, liquid glucosamine sulfate or a mixture of both glucosamine sulfate and glucosamine HCL. The best products are also combined with ingredients that work synergistically with glucosamine to help rebuild cartilage, stop pain, reduce inflammation, and increase mobility. These include:

  • Chondroitin Sulfate
  • Boswellin
  • Yucca Powder
  • Manganese Ascorbate
  • Bromelain
  • Vitamin C
  • Omega 3 Fatty Acid
  • Omega 6 Fatty Acid
  • Vitamin A
  • Vitamin E

While the majority of research to date has been done on capsule products, liquid products provide greater absorption and greater bio-availability meaning it is more beneficial in the treatment of your dog or cat's arthritis. Overall, the product that came closest to these recommendations is Syn-flex®.
