Usage Instructions and Side Effects

Usage Instructions for Liquid Glucosamine Formula Syn-flex®


Recommended daily dosage for humans is 1/4 of an ounce per day of Liquid Glucosamine Formula Synflex. You may wish to double the dose to 1/2 oz. the first ten days for maximum effectiveness. If you are over 230 pounds you may find that staying with a 1/2 oz. daily dosage works more effectively.

1/4 oz. is equivalent to 1.5 teaspoons (or one half of a tablespoon). To measure this accurately, Syn-flex includes a "measuring reservoir."

To use this, simply open the reservoir cap and squeeze until the level of liquid reaches the desired amount. There is a 1/4 oz. and 1/2 oz. marker on the bottle. Once it reaches this level, you can either pour onto a spoon, mix it with your favorite drink, or take it straight from the bottle.


When you first begin to take Syn-flex, you may wish to keep a journal of how you feel each day. The great majority of users experience noticeable relief within ten to fifteen days. In severe cases, it may take up to a month of daily usage to ease the pain and slow the progression of your osteoarthritis.

Side Effects, Interactions, Contraindications
In comparison to the dangerous side effects of NSAIDS and Cox-2 Inhibitors, there are very few side effects to using Syn-flex.

  • While unlikely, those who are allergic to shellfish may experience a reaction to Syn-flex. In most cases, allergies are caused by proteins in shellfish, not chitin (a carbohydrate from which Glucosamine is extracted.) Therefore, it should be safe for someone with an allergy to shellfish or iodine to take Glucosamine. However, if you notice any reaction, you should consult your physician and you may choose to discontinue taking Syn-flex.
  • If you are pregnant or lactating you should consult your physician before beginning to take Glucosamine. We recommend that individuals with diabetes check their blood glucose levels frequently when initiating Glucosamine into their regimen.
  • High dosages of Syn-flex may cause minor gastric problems, nausea, diarrhea, or indigestion in a small percentage of users. If this occurs, split the dosage between morning and evening, take following a meal, or reduce dosage.

Other than these, there are no side effects or contraindications to using Syn-flex. While osteoarthritis drug treatments like Vioxx and Celebrex have a number of serious and potentially fatal side effects, Syn-flex is a very safe product. As well, those drugs do not assist in rebuilding damaged cartilage. (They are designed to ease pain). Glucosamine found in Syn-flex not only slows the progression of your arthritis and eases your pain, it also is able to aid in rehabilitating deteriorated cartilage and reduce inflammation.
