How do I measure this? 

Two measuring spoons are included. The small spoon is 10 Billion CFU (0.1g) and the big spoon is 80 Billion CFU (0.8g). 

 

Why powder and not capsules?

Our probiotic powder has no additives. Many people don't realize that a lot of additives worsen their symptoms. Additionally, the microbiome in your mouth, esophagus, and stomach are incredibly important to your health. Taking our flavorless probiotic powder keeps those areas healthy. 

 

Why High Potency? How much should I take? 

Using a dose less than 25 Billion per day will have limited health benefits -- you will need a higher potency to get desirable results. Many people have used other probiotic brands with minimal results because of their low potency. 

It depends on the person and the issue that is being addressed. You’ll start to see results at a minimum of 25 Billion CFUs per day. The average daily dose by our customers is between 200-400 Billion CFUs per day. Some people see significant results with dosages as high as 800 Billion CFUs per day.

Can infants and children take probiotics? 

Based on existing research, infants can start taking probiotics at 6 months of age. 

How much probiotics can an infant take? 

Infants can take up to 50 Billion CFU per day. 

What are CFUs?

CFU stands for Colony Forming Unit. This is the bacterial count of probiotics. 

Why aren’t BulkProbiotics enteric coated? 

Enteric coated probiotics are mainly a marketing gimmick. The strains that are used at BulkProbiotics are vetted to have excellent acid and bile tolerance as well as the capacity to survive intestinal transit. 

What happens if I leave the probiotics outside of the refrigerator for a couple of days? 

2 year temperature stability testing has been performed on our probiotics and the loss would be negligible. Our probiotics can remain at room temperature (or travel) for 2-3 weeks with limited loss, however, it is best to store the probiotics in the refrigerator for optimum potency. 

Why do some individuals get a “die-off” reaction? 

This is due to a ‘war’ that occurs between the probiotics and the bad bacteria in your body. If there is a large imbalance in your gut bacteria, the die-off reaction will be higher. To avoid this we recommend that you gradually increase your dosage starting with about 25 Billion CFU per day and increase every few days over a couple of weeks. 

Do your probiotics contain any dairy or gluten? 

Our probiotics are dairy and gluten free. They do not utilize milk, milk derivatives, GOS, or Inulin as additional ingredients in the fermentation media. 

When should I take probiotics? Is it ok to take probiotics with drugs, vitamins, or antibiotics? 

As a digestive aid, it is best to take 30 minutes before a meal; otherwise, it is also ok to take on an empty stomach in the morning or at bedtime (at least 2 hours after eating). Probiotics should not be taken with antibiotics (take 2 hours before or after taking antibiotics). 

What is the return policy?

We accept returns within 30 days for all 10g probiotic powders that are unopened. We do not accept returns for any other sizes. The 10g size is available to experiment to help you find the right probiotic strains for you. 

The gut microbe B. longum may improve the human immune response and help prevent gut disorders. Early evidence suggests that it may also suppress allergies, reduce cholesterol, and improve skin health. Learn more here.

What is Bifidobacterium longum?

Bifidobacterium longum is a Gram-positive, rod-shaped species of bacteria naturally present in the human GI tract. It’s subspecies B. longum subsp. infantis is one of the earliest bacteria to colonize the infant gut. B. longum is often added to food products as a probiotic with various health benefits.

Previously considered separate species, B. infantis and B. suis were shown to be subspecies of B. longum [1].

Mechanisms of Effect

Various studies have investigated B. longum’s effect on the cellular level. These may or may not reflect the mechanisms of B. longum probiotics in the human body; however, they may help account for some of the observed effects of these probiotics in human studies.

Under inflammatory conditions, B. longum:

  • Decreased Th1-related cytokines (T-bet, IL-2, and IFN-γ) and Th17-related cytokines (IL-12p40, RORγt, IL-17A, IL-21, and IL-23), and increases Treg-related molecules (Foxp3, IL-10, and TGF-β) [29, 73, 40, 41, 3, 27].
  • Decreased IL-1α [39], IL-1β [28, 35, 40], IL-6 [74, 38, 27] and IL-18 [35].
  • Decreased TNF-α expression [28, 39, 38, 27].
  • Increased IL-27 [41].
  • Decreased CD80 and CD40 [73], CXCL1 [40, 27], CRP [38], iNOS and antimicrobial peptides Reg3b and Reg3g [27].

In infectious conditions, B. longum:

  • Increased natural killer (NK) cell activity [4, 6, 9].
  • Increased serum IgA [4] and decreased IgG2a productions [13].
  • Increased IL-2, IL-12, and IL-18 [9].
  • Decreased IL-6 [9, 10] and IL-8 [15].
  • Decreased TNF-α [9].
  • Both increased [8] and decreased IL-10 [15], and decreased [10, 13] and increased IFN-γ [9].

In allergic conditions, B. longum:

  • Decreased IgE and improves the IgG2a/IgG1 ratio [48, 50, 75, 75, 76].
  • Increased IgA [77].
  • Increased Th1 cytokine and decreased Th2 cytokine production [48].
  • Decreased IL-4 [75, 46] and IL-5 [75] [a case where IL-5 was increased: 46].
  • Increased IL-10 [50], IL-12 [76, 76] and TGF-β [50].
  • Increased [45, 76] or decreased IFN-γ [46].
  • Suppressed MDC and TARC [43].
  • Increased CD4+CD25+Foxp3+ Treg cells [49].

In celiac disease, B. longum:

  • Decreased TNF-α [18, 20].
  • Increased NFκB [20].
  • Increased IL-10 [20].
  • Reduced CD3⁺ T [18], CD4+ and CD4+/Foxp3+ cells [20] and increased CD8+ T [20].

Safety

  1. longum is considered safe, but should be avoided in immunocompromised individuals, people with organ failure, and dysfunctional gut barrier, where probiotics may lead to infection. To avoid adverse effects, talk to your doctor about whether probiotics could be appropriate for you.
