Combining vitamin B12 with specific probiotics, such as Lactobacillus reuteri and Bifidobacterium bifidum, can enhance B12 absorption and recycling in the body, supporting better overall health.
-
Scientific studies have demonstrated that probiotics improve the bioavailability of B12, making supplementation more effective and beneficial for energy production, brain function, and overall well-being.
-
Incorporating probiotic-rich foods or supplements into your diet can help maintain a healthy gut microbiome, optimizing the absorption and utilization of B vitamins, including B12.
Why you need B12 & Probiotics?
Enhancing Vitamin B12 Absorption: The Role of Probiotics
Vitamin B12 is essential for various bodily functions, including DNA synthesis, red blood cell formation, and neurological function. While many people take B12 supplements to meet their daily requirements, emerging research suggests that combining B12 with probiotics can enhance its absorption and efficacy.
The Connection Between Probiotics and Vitamin B12
Probiotics are live bacteria and yeasts that promote a healthy gut microbiome. A balanced gut microbiome is crucial for efficient digestion and nutrient absorption. Certain probiotic strains are particularly effective in synthesizing and recycling B vitamins, including B12.
Key Probiotic Strains for B Vitamin Recycling
- Lactobacillus reuteri: This strain has been shown to synthesize vitamin B12 and support overall gut health. A study published in the Journal of Applied Microbiology highlighted its role in B12 synthesis and gut microbiome balance (1).
- Lactobacillus plantarum: Known for its ability to produce folate (B9) and potentially enhance B12 absorption. Research in the Journal of Clinical Gastroenterology emphasized its importance in nutrient absorption and gut health (2).
- Bifidobacterium bifidum: This strain contributes to the production of B vitamins, including B12, and supports digestive health. The International Journal of Food Microbiology documented its role in vitamin synthesis and gut microbiome maintenance (3)
- Bifidobacterium longum: Involved in synthesizing various B vitamins, aiding in gut health. A study in the American Journal of Clinical Nutrition noted its effectiveness in maintaining a healthy balance of gut bacteria and promoting B vitamin synthesis (4).
- Lactobacillus acidophilus: Supports B vitamin production and enhances nutrient absorption. Research published in the Journal of Nutrition has shown its positive impact on gut health and nutrient uptake (5).
Top 10 Sources of B12 in Foods
Here are the top 10 sources of vitamin B12, which can help ensure you get an adequate amount of this essential nutrient:
Clams
Clams are one of the best sources of vitamin B12. They are also rich in iron and other essential minerals. A 3-ounce serving of clams can provide more than 1,400% of the daily value for B12.
Liver and Organ Meats
Beef liver, in particular, is extremely high in B12. A 3-ounce serving of beef liver contains more than 1,000% of the daily value. Organ meats from lamb and chicken are also good sources.
Fish (especially mackerel, sardines, and salmon)
Mackerel, sardines, and salmon are excellent sources of vitamin B12, as well as omega-3 fatty acids. A serving of mackerel can provide over 500% of the daily value for B12.
Meat (especially beef, pork, and lamb)
Various cuts of meat, including beef, pork, and lamb, are rich in vitamin B12. A 3-ounce serving of beef steak can provide about 467% of the daily value.
Dairy Products
Milk, yogurt, and cheese are good sources of vitamin B12. A cup of milk provides about 18% of the daily value for B12.
Eggs
Eggs, particularly the yolks, contain a moderate amount of B12. Two large eggs provide about 22% of the daily value.
Fortified Foods
Many plant-based milks (such as soy, almond, and oat milk), breakfast cereals, and nutritional yeast are fortified with vitamin B12. These can be particularly important sources for vegetarians and vegans.
Shellfish (especially crab and shrimp)
Crab and shrimp are rich in vitamin B12. A 3-ounce serving of crab can provide over 100% of the daily value.
Chicken and Turkey
Poultry, including chicken and turkey, contains vitamin B12. A 3-ounce serving of roasted turkey can provide about 29% of the daily value.
Fortified Nutritional Yeast
Nutritional yeast is often fortified with vitamin B12 and can be sprinkled on various dishes. Two tablespoons can provide up to 733% of the daily value, making it an excellent source for vegans.
Scientific Evidence Supporting Probiotics and B12 Absorption
Several studies have highlighted the synergy between probiotics and B12 absorption. For example, a study published in the British Journal of Nutrition demonstrated that probiotics could enhance the bioavailability of dietary B12 (6). Another research in the Journal of Agricultural and Food Chemistry found that probiotics improve the intestinal absorption of B12, making supplementation more effective (7).
Practical Applications
To reap the benefits of this synergy, consider incorporating probiotic-rich foods into your diet. Foods such as yogurt, kefir, sauerkraut, and other fermented products are excellent sources of these beneficial bacteria. Alternatively, a probiotic supplement containing strains like Lactobacillus reuteri, Lactobacillus plantarum, Bifidobacterium bifidum, Bifidobacterium longum, and Lactobacillus acidophilus can be effective.
Conclusion
Combining vitamin B12 with specific probiotics can enhance its absorption and utilization in the body. By maintaining a healthy gut microbiome through the use of probiotics, you can improve your overall health and ensure that your body efficiently recycles essential B vitamins.
