Next post is about one of the most researched protein, collagen.

Below are the three major side effects of taking kollageeni


Animal sources remain the major raw materials for the production of collagen supplements. Collagen tablets which are produced from marine sources, such as sea urchins and shellfish, contain greater amounts of calcium, which can dramatically increase the level of calcium in the patient by means of supplements. This can result in hypercalcemia in individuals.

According to MedlinePlus, high levels of calcium known as hypercalcemia may appear as possible side effects of collagen supplements. The normal values for calcium levels range from 8.5 to 10.2 mg/dl – reading above 10.2 mg/dl is regarded to be hypercalcemic. While calcium is good for us, the old that says “too much of everything is bad” is applicable here. A large amount of calcium in the body results in constipation, bone pain, fatigue, nausea, vomiting and abnormal heart rhythms. Consumption of calcium supplements with this type of collagen tablet should be done with caution.


Since collagen products are made from animal sources, an allergic reaction seems to be a major concern. Hypersensitivity reactions may occur as the side-effects of consuming collagen supplements. As published by the National Institute of Allergy and Infectious Diseases website, hypersensitivity reactions appear as an abnormal response of the immune system against allergens, such as food, drugs, and supplements. People with hypersensitivity to shellfish and eggs may have a serious reaction. Other supplements of collagen obtained from eggs and their derivatives may also cause food sensitivity, especially in kids. A hypersensitivity test is performed before the injection of the injectable collagen.


When supplemented are produced from sea sources and taken orally, it usually leaves a bad taste in the mouth of the user. Drinking fruit juice with this type of oral collagen may cover an unpleasant taste. Fruits such as oranges, apples, grapes, and tomatoes, which are acidic, have been found to decrease the strength and potency of collagen supplements; in that case, they should be avoided. Marine collagen supplements usually have an unpleasant taste and scent that is not very suitable for most patients.
