Glucosamine supplement capsules spilling from a bottleGlucosamine is a naturally occurring chemical found in the body, most notably in the fluid that surrounds the joints. Glucosamine can also be found in nature, like in the shells of shellfish, and is widely used in joint and dietary supplements. We know there are a million types of joint supplements out there and many of them are filled with ingredients you've never heard of. It's important to know which ingredients are in your supplement, and why, plus any side effects they may have. To help you learn more about glucosamine's side effects, we've compiled a short list of what you may experience with this compound.

1. High Blood Pressure

Some studies suggest that glucosamine sulfate can increase insulin levels, resulting in increased blood pressure. If you are going to take glucosamine, or a supplement that contains it, we recommend monitoring your blood pressure.

2. Shellfish allergy

Because some glucosamine products are made with the shells of shellfish there is a slight concern that the compound can cause an allergic reaction in people with a shellfish allergy. However, allergic reactions from shellfish are generally caused by the meat of the animal, not the shell. Even so, if you have a shellfish allergy, check with your healthcare provider before taking glucosamine products.

3. High Cholesterol

Previous research in animals suggests that glucosamine may increase cholesterol levels, however it is not established that this same occurrence is true in humans. As mentioned earlier, glucosamine can increase insulin levels, which may lead to high cholesterol. If you have high cholesterol and take glucosamine, we highly suggest closely monitoring your cholesterol.

4. Sleeping Issues

Glucosamine may cause drowsiness or sedation. In some cases it may cause insomnia.

5. Stomach Issues

Glucosamine may cause the following stomach related issues:

  • stomach pain
  • a feeling of heaviness in the stomach
  • constipation
  • diarrhea
  • gas
  • indigestion
  • nausea
  • upper abdominal tenderness
  • vomiting

As with most supplements or medications, side effects may happen, but are not guaranteed, and reactions are different in each person. Now that you are aware of glucosamine's side effects we hope you are more prepared to choose the correct joint supplement or medication for you.
