What is Acidosalus ® ?

Acidosalus ® is the name of the MarinaLab product range. "Acid health" in Latin means probiotics with which we started our story. Acidosalus ® is a natural preparation created by fermentation of milk with the help of powerful bacteria from the genus Lactobacillus and Bifidobacterium.

What does it contain?

Acidosalus ® contains a very high concentration of live germs per milliliter of preparation (min 109 to 1011 CFU/mL), and a natural antibiotic substance that has a broad antimicrobial spectrum that blocks the growth and development of pathogenic bacteria and fungi in the intestines and mucous membranes, and is rich in group B vitamins including folic acid (B9).
Folic acid plays a very important role in the metabolism of our body: hematopoietic factor, growth factor, it is important in pregnancy to preserve the fetus, it protects the nervous system, it is important for the function of the liver, in the formation of new cells and in the healing of wounds.

White drop of health

It's still 1953. year prof. Dr. Kruna Tomić Karović proved the antibiotic effect of milk fermented with Lactobacillus bacteria prepared in a laboratory, and in cooperation with doctors conducted many clinical tests and in this way helped urological patients with stubborn infections, then with chronic inflammation of the middle ear, cystitis, gastritis, colitis, and children's diarrhea caused by salmonella.

The strain for making the Acidosalus ® preparation tested on mice with an induced tumor showed a positive effect. Taking Acidosalus ® preparation reduces the risk of tumor formation.

Improvement of intestinal microflora

Cultures of lactic acid bacteria are natural inhabitants of the digestive and genitourinary systems of humans and animals. Live microorganisms that are also found in breast milk, inhabit the intestines and develop our microbiome from birth.

A developed microbiome affects the good functioning of the digestive system, a strong immune system and helps the normal function of the brain.

The battle against bacteria, viruses and fungi

Bacteria from the genera Lactobacillus and Bifidobacterium are characterized by extremely effective antibiotic activity; prevents the growth and development of various bacteria, viruses and fungi (Salmonella, Shigella, Escherichia coli, rotavirus, HPV, Candida albicans).

Due to its ability to settle in the digestive tract, it improves the overall condition of the intestinal microflora, affecting many pathological conditions that are the result of weakened immunity.

Fermented dairy products

Acidosalus ® contains the enzyme lactase, so it can be taken by people allergic to lactose (milk sugar).
The positive medicinal effect of Lactobacillus acidophilus has been confirmed by numerous scientific studies around the world.
Because of these and practically proven facts, Acidosalus ® has therapeutic value.
