NOTE: Probiotics are measured by their potency (CFU per gram or number of probiotic cells per gram), not just by how much powder there is. Probiotic powders can be manufactured in different potencies (10 Billion CFU per gram, 100 Billion CFU per gram, 500 Billion CFU per gram, etc). The higher the potency per gram, the less powder you need to take. For example, you would need to take 5 grams of 100 Billion CFU per gram to equal 1 gram of 500 Billion CFU per gram.

B. Lactis 600 billion CFUs/gram (Live Probiotic, No Fillers)

Histamine Free.

Ingredients: Bifidobacterium Lactis

NOTE: Keep refrigerated upon arrival. 

The probiotics are freeze dried so no ice packs, etc are needed during shipment. 

DO NOT purchase no filler probiotic powder if it is NOT refrigerated. Fillers like maltodextrin, etc keep probiotics stable outside of the refrigerator but cause a lot of digestive problems so we don't use them. The CFU count will be much lower than advertised for no filler powders that are not refrigerated.

We keep all our powders in the refrigerator before shipment.

FREE US SHIPPING. 

*Free international shipping over $100 USD (use code FREESHIPPING at checkout). 

How do I measure this? 

Two measuring spoons are included. The small spoon is 60 Billion CFU (0.1g) and the big spoon is 480 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 5 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.

B. lactis is an important component of the healthy gut flora. It may promote GI well-being, especially in children, and some evidence suggests it may help the body prevent and fight off infections. 

What is Bifidobacterium lactis?

Bifidobacterium lactis is a gram-positive rod-shaped bacterium which can be found in the gut of most mammals, including humans. It is considered to be part of the healthy, beneficial gut flora [1].

3) Infant Growth

1. animalis spp. lactis supplementation had a positive effect on growth in 594 vulnerable infants, such as infants born to mothers with HIV [37], and preterm infants [38].

4) Obesity

Daily ingestion of milk containing B. animalis ssp. lactis significantly reduced the BMI, total cholesterol, low-density lipoprotein, and inflammatory markers in a study of 51 human patients with metabolic syndrome [39].

In the same study, B. animalis ssp. lactis significantly reduced BMI, total cholesterol, low-density lipoprotein and inflammatory cytokines [40].

The presence of B. animalis was also found to be negatively associated with BMI in two studies of a total of 378 human volunteers [41, 42].

1. animalis ssp. lactis reduced weight gain, fat mass and improved glucose tolerance in obese mice [43].
2. animalis ssp. lactis improved glycemia and reduced insulin levels in obese rats [44].

5) Anemia in Children

6) Immunity

1. animalis ssp. lactis augmented immunity in 26 healthy young women [46].
2. animalis spp. lactis supplementation in pregnancy influenced fetal immune parameters as well as immunomodulatory factors in breast milk in 71 women [47].

In a study of 172 otherwise healthy infants, B. animalis ssp. lactis mitigated the negative immune-related effects of not breastfeeding and cesarean delivery, possibly by augmenting the immune response, evidenced by increased anti-rotavirus- and anti-poliovirus-specific IgA [48].

2. animalis ssp. lactis inhibited inflammation in elderly volunteers [54].
3. animalis ssp. lactis reduced inflammatory and T cells mediators, promoted regulatory T cells specific markers, reduced weight loss, and attenuated epithelial damage in mice with colitis [55].

9) Aging

1. animalis spp. lactis beneficially modified gut microbiota in 20 elderly volunteers, by increasing Bifidobacteria, Lactobacilli, and Enterococci and reducing Enterobacteria [56].
2. animalis spp. lactis enhanced natural immunity in 25 healthy elderly subjects [57].
3. animalis spp. lactis increased leukocyte phagocytic in the elderly. Increases in the proportions of total, helper (CD4(+)), and activated (CD25(+)) T lymphocytes and natural killer cells were also observed [58, 59, 60].

10) Diabetes

1. animalis ssp. lactis reduced weight gain and fat mass and improves glucose tolerance in diabetic mice [43].

This probiotic also improved diabetes-induced total cholesterol and triglyceride (TG) levels and increased the muscle glycogen content [61].

11) Antioxidant Activity

1. animalis culture supernatant, intact cells, and intracellular cell-free extracts all effectively scavenged free radicals and significantly enhanced the activities of antioxidative enzymes in mice [62].

12) Celiac Disease

Live B. animalis ssp. lactis bacteria directly counteracted the harmful effects exerted by celiac-toxic gluten (or, rather, a component of gluten called gliadin) on human intestinal cells [63].

13) Autoimmune Disease

In rats with experimental autoimmune encephalomyelitis, B. animalis significantly reduced the duration of clinical symptoms [52].

14) Oxalate

1. animalis ssp. lactis possesses the OXC gene, encoding oxalyl-coenzyme A (CoA) decarboxylase, a key enzyme in oxalate degradation [64].
2. animalis ssp. lactis significantly decreased urinary oxalate excretion in mice with hyperoxaluria by degrading dietary oxalate thus limiting its absorption across the intestine [65].
