Undissociated lactic acid can cross the rumen wall to the blood, [29] where it dissociates, lowering blood pH. Both L and D isomers of lactic acid are produced in the rumen; [24] these isomers are metabolized by different metabolic pathways, and activity of the principal enzyme involved in metabolism of the D isomer declines greatly with lower ...
In lactose intolerant people, the fermentation of lactose to lactic acid has been shown in small studies to help lactose intolerant people. The process of fermentation limits the amount of lactose available. With the amount of lactose lowered, there is less build up inside of the body, reducing bloating.
It was once believed that lactic acid build-up was the cause of muscle fatigue. [8] The assumption was lactic acid had a "pickling" effect on muscles, inhibiting their ability to contract. Though the impact of lactic acid on performance is now uncertain, it may assist or hinder muscle fatigue.
Acid consumption from poisoning such as methanol ingestion, elevated levels of iron in the blood, and chronically decreased production of bicarbonate may also produce metabolic acidosis. Metabolic acidosis is compensated for in the lungs, as increased exhalation of carbon dioxide promptly shifts the buffering equation to reduce metabolic acid.
This build-up of lactic acid was thought to be a toxic metabolic waste product that caused the perception of pain at a delayed stage. This theory has been largely rejected, as concentric contractions which also produce lactic acid have been unable to cause DOMS. [5]

UNSPOTTED 4X® Acid Jelly Night Serum. The "4X" in this serum's name is thanks to the 15 percent blend of lactic, azelaic, glycolic, and tranexamic acids, which together help reduce the appearance ...
Lactic acid is used as a food preservative, curing agent, and flavoring agent. [51] It is an ingredient in processed foods and is used as a decontaminant during meat processing. [52] Lactic acid is produced commercially by fermentation of carbohydrates such as glucose, sucrose, or lactose, or by chemical synthesis. [51]
