Calcium lactate is a dietary supplement used to provide extra calcium to individuals that are lacking calcium in their diet. Calcium lactate does not contain milk and therefore safe for use if you're allergic to milk, according to the Food Allergy and Anaphylaxis Network. If you have been diagnosed with a dairy allergy, talk with your doctor before using any supplement. If you experience any symptoms of a severe allergic reaction, such as shortness of breath, hives or facial swelling, Drugs.com recommends getting emergency medical attention.
Background
A dairy allergy is a hypersensitivity of the immune system to the proteins found in dairy products. Kids Health states that after you ingest dairy, your body begins to protect itself from the proteins, although they are safe. Antibodies are formed to attack the diary proteins and trigger the production of histamine. Histamine is the chemical responsible for most food-related allergic symptoms. A dairy allergy is commonly confused with lactose intolerance or a milk protein intolerance and needs to be diagnosed by a doctor.
Concern
MayoClinic.com states that dairy products are one of the main sources of calcium. Because the best treatment to prevent dairy allergy symptoms is to avoid dairy, you may lack calcium in your diet. Certain foods, such as organges, green, leafy vegetables and fortified non-dairy substitutes, can supply you with your daily needed calcium intake. If you're concerned that your diet is not full of enough calcium, talk to your doctor about taking a calcium lactate supplement.
Calcium Lactate Solution
Calcium lactate may be a solution if your allergic to dairy products and do not think you're receiving enough calcium daily. Calcium lactate should not be used by people with kidney disease or a parathyroid disorder, according to Drugs.com. Calcium lactate may cause some side effects, such as dry mouth, thirst, nausea, decreased appetite, vomiting, constipation and excessive urination. Talk to your doctor if you're pregnant, could become pregnant or breastfeeding about the safety of this supplement.
Symptoms
If you suspect you have a milk allergy, you will experience common milk allergy symptoms. Asthma is a common symptom of a milk allergy, such as wheezing, coughing, shortness of breath and chest tightness. You may also experience diarrhea, vomiting, cramping and nausea, according to Kids Health. Nasal congestion, sinus pressure pain, a runny nose, sneezing, watery eyes and a scratchy throat may also develop after drinking milk.
