1. Helps improve digestion: The RMS Stadtgen 21% Lactic Acid Drops contain lactic acid, which is known to aid in digestion by breaking down food particles and promoting the growth of beneficial bacteria in the gut.
2. Boosts skin health: Lactic acid is also known for its skin-enhancing properties. These drops help to exfoliate dead skin cells, reduce the appearance of fine lines and wrinkles, and improve overall skin texture and tone.

The Active Ingredient Is: Lactic Acid (L-(+)-lactic acid)

Lactic acid is a basically naturally occurring organic acid involved in everyday metabolic processes and gut environment regulation.

This form signifies the L-(+)-enantiomer present in water as a legacy postbiotic component, without reference to extra ingredients or dosages.

What Lactic Acid Do?

Lactic acid helps keep gut pH and acts as a metabolic substrate in the digestive system, supporting the balance of fermentation processes in the gut.

This approach may contribute to gut barrier function and microbiome balance, in line with EFSA-driven understanding of intestinal health, as discussed by Dr. Tsilingiri from the University.
