Common Names and Scientific Distinctions
While the most direct answer to "What is another name for Lactobacillus acidophilus?" is acidophilus, it's important to understand the nuance. The term acidophilus refers to the specific species of bacteria, L. acidophilus. You might also see the shortened form, L. acidophilus, particularly in scientific or clinical literature. In commercial products, especially dietary supplements and fermented foods like yogurt, it's common for packaging to use just the term acidophilus to indicate its presence. Additionally, given that L. acidophilus is a well-known probiotic, it is sometimes included under the broader, non-specific term probiotic.
Where to Find Lactobacillus acidophilus under Different Names
Lactobacillus acidophilus can be found in various foods and dietary supplements. Knowing its different names can help consumers identify it on labels and in ingredient lists. Live-culture yogurts, fermented milk drinks like kefir, and fermented vegetables like sauerkraut are primary dietary sources. In the supplement industry, it is sold in capsules, powders, and tablets under its full scientific name, its common name, or a brand-specific designation.
The Role of Lactobacillus acidophilus in Health
This bacterium is valued for its ability to produce lactic acid from carbohydrates, which helps create an acidic environment that can inhibit the growth of harmful bacteria. Its primary habitat is the gastrointestinal tract, though it's also a part of the healthy microbiota in the mouth and vagina. Supplementing with L. acidophilus can support digestive and immune health, especially when the body's natural bacterial balance is disrupted by illness or medication. The bacteria compete with pathogens for resources and adhesion sites within the gut, helping to maintain a healthy microbial balance.
Other Related Lactobacillus Species
It is essential not to confuse L. acidophilus with other species in the Lactobacillus family, some of which are also used in food production and probiotic supplements. While many lactobacilli share the lactic acid-producing characteristic, their specific functions and applications can differ. For example, Lactobacillus bulgaricus is another species commonly used in yogurt production, but it is distinct from L. acidophilus. When choosing a probiotic product, understanding the specific strains included can be beneficial for targeted health effects.
A Comparison of Common Probiotics

|---|---|---|---|---|
| Common Name | Acidophilus | B. lactis | L. rhamnosus, GG | S. boulardii |
| Classification | Probiotic bacteria | Probiotic bacteria | Probiotic bacteria | Probiotic yeast |
| Primary Uses | Diarrhea, IBS, lactose intolerance, vaginal health | Digestive health, immune support | Antibiotic-associated diarrhea, overall gut health | Diarrhea, traveler's diarrhea |
| Habitat | Intestinal tract, mouth, vagina | Intestinal tract | Intestinal tract | Intestinal tract, temporary |
| Natural Sources | Yogurt, kefir, some cheeses | Yogurt, fermented dairy | Some cheeses, yogurts, fermented milks | Fermented foods, some fruit |
Dietary Sources of Lactobacillus acidophilus
Beyond supplements, incorporating foods rich in L. acidophilus into your diet is a simple way to increase your probiotic intake. Look for products that specify "live and active cultures" on the label to ensure the bacteria are still active and viable.
- Yogurt: A classic source, especially those made with live and active cultures.
- Kefir: A fermented milk drink known for its high probiotic content.
- Acidophilus Milk: Milk that has been fermented with L. acidophilus.
- Miso: A traditional Japanese paste made from fermented soybeans, which may contain L. acidophilus.
- Tempeh: An Indonesian food made from fermented soybeans.
- Sauerkraut: Fermented cabbage that can be a natural source of this probiotic.
How to Choose the Right Probiotic
When selecting a probiotic, especially in supplement form, it's crucial to understand the different strains and their intended uses. While acidophilus is a popular choice for general gut and vaginal health, other strains like Bifidobacterium or Lactobacillus rhamnosus might be better suited for specific conditions. Always read the label carefully to confirm the species and strain. The dosage, measured in Colony-Forming Units (CFUs), can also vary significantly between products. It is advisable to consult a healthcare provider, particularly if you have underlying health issues or a compromised immune system.
Conclusion
In summary, the most common other name for Lactobacillus acidophilus is simply acidophilus. This beneficial probiotic bacterium is widely known for its ability to produce lactic acid, support digestive health, and strengthen the immune system. Whether obtained through fermented foods like yogurt or from dedicated dietary supplements, acidophilus plays an important role in maintaining a balanced microbiome. Its various names reflect its scientific classification and common commercial usage, but all refer to the same helpful microorganism. For targeted health benefits, it's always best to check product labels for specific strains and consult a healthcare professional. You can explore additional health benefits and scientific research on this topic through authoritative sources like the National Institutes of Health (NIH).
