Albumīns is one of the most important proteins in our body. It helps maintain fluid balance in the blood and transports many essential substances. Many people are unaware of how significant albumin is for everyday health, yet it affects blood pressure, nutrient transport, and even immunity. In this article, we will explain step by step what albumin is, how it works, and why it is so important.
What Exactly Is Albumīns?
Albumin is the main protein in blood plasma. It is produced by the liver and accounts for about half of all plasma proteins. In a healthy person, blood contains 3.5–5 g/dL of albumin. It is a water-soluble protein with a long half-life, making it stable in the body.
The word albumīns comes from the Latin “albumen,” meaning egg white, because a similar protein is found in eggs. However, human albumin is a specific blood protein called serum albumīns.
The Role of Albumīns in the Body Albumin performs several crucial functions:
- Maintains oncotic pressure – it prevents fluid from leaking out of blood vessels into tissues, thus preventing edema in the legs or abdomen.
- Transports substances – albumin carries hormones, fatty acids, vitamins, bilirubin, and even some medications through the blood.
- Acts as an antioxidant – protects cells from free radical damage.
- Serves as an amino acid reserve – if the body lacks protein, it can use albumin as a source.
- Helps maintain blood volume and pressure.
Without sufficient albumin levels, the body cannot function normally. For example, low levels cause edema and weakened immunity.
How Is Albumīns Produced and Regulated?
The liver synthesizes about 10–15 g of albumin per day in a healthy adult. It enters the bloodstream quickly, with little storage in the liver. Production is influenced by nutrition, hormones, and inflammation. If the liver is diseased, albumin levels drop.
Dietary Sources of Albumīns To maintain good albumin levels, eat protein-rich foods. Here are the best sources:
- Eggs (especially the white) – one of the best sources with high biological value.
- Dairy products – milk, cheese, yogurt.
- Fish – salmon, tuna.
- Meat and poultry.
- Legumes – beans, lentils.
- Nuts and seeds – almonds, sunflower seeds.
Adults need about 0.8 g of protein per kg of body weight per day. Athletes and pregnant women need more.
Health Benefits of Good Albumin Levels Albumīns provides many benefits:
- Prevents edema and helps maintain blood pressure.
- Ensures transport of hormones and vitamins.
- Supports tissue healing after injuries or surgeries.
- Assists the immune system by binding toxins.
- Improves overall health, especially in chronic diseases.
Studies show that normal albumin levels are associated with better prognosis in patients with liver disease or burns.
When Albumīns Levels Are Low: Symptoms and Causes Low albumin (hypoalbuminemia) causes:
- Edema in the legs, arms, or abdomen.
- Fatigue and weakness.
- Easy infections.
- Slow wound healing.
Causes include:
- Liver diseases (cirrhosis, hepatitis).
- Kidney problems (nephrotic syndrome).
- Inadequate nutrition or malnutrition.
- Inflammation or chronic diseases.
- Burns or major trauma.
Medical Albumīns: When Is It Used? In medicine, human albumin infusions (e.g., 20% or 25% solutions) are used. They help:
- Restore blood volume after bleeding or shock.
- Treat severe burns or surgeries.
- Stabilize blood pressure in liver cirrhosis.
- Use during cardiopulmonary bypass operations.
For example, products like Human Albumīns 20% 50ml from Biotest Pharma are used to quickly increase blood volume. They are administered slowly intravenously to avoid problems.
Side Effects and Risks of Medical Albumīns Although generally safe, possible side effects include:
- Nausea or vomiting.
- Fever or chills.
- Rapid heartbeat.
- Rash or redness.
- Rarely – allergic reactions.
Always use under a doctor’s instructions, as too rapid infusion can cause fluid overload.
How to Maintain Healthy Albumīns Levels? Here are practical tips:
- Include protein in every meal.
- Add eggs to breakfast.
- Drink enough water.
- Manage chronic diseases.
- Get regular blood tests.
If you are at risk, consult your doctor.
Conclusion
Albumīns is truly an essential protein that maintains blood balance, transports substances, and protects health. From dietary sources like eggs and milk to medical infusions – it supports us in daily life and in crises. Maintaining good albumin levels helps your body defend against many problems.
