Pro Culture™

The most advanced live culture supplement from Bulk™, providing an advanced blend of live cultures, spores and synergistic ingredients into a single, powerful capsule, including LactoSpore®, MicrobiomeX®, Synbalance Sport Max™ and inulin. Lab tested for banned substances and approved for athletes. If you don’t love it, we’ll give you your money back*.

We designed Pro Culture™ to be the very best live culture daily supplement available. Using a blend of five highly dosed live cultures, it offers the most advanced blend of cultures and synergistic ingredients on the market today. And as with all of our Bulk™ PRO products, we’re completely transparent about every ingredient and the quantity used, so you know exactly what you’re putting in your body and why.

Pro Culture™ contains five strains of live bacterial cultures: Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus acidophilus, Bifidobacterium lactis, and LactoSpore®’s proprietary Bacillus coagulans preparations. We’ve dosed them potently to provide 20 billion CFUs (colony forming units) per two capsule serving, 2.5 times stronger than other leading blends. On top of that, we blended them with a range of synergistic ingredients to provide optimal nutritional support.

  • Inulin
    Part of a class of dietary fibres called fructans, inulin is part of a larger group of naturally occurring polysaccharides. It’s found in a number of foods, including many pulses and vegetables.
  • MicrobiomeX®
    An innovative ingredient extracted from Citrus sinensis which is a natural source of flavanone glycosides. MicrobiomeX® is standardised to provide 80% hesperidin and 3.5% naringin, two compounds typically found in the peel of citrus fruits.
  • Synbalance Sport Max™ Blend
    We combined four live strains of bacteria into a single blend to create Synbalance Sport Max™. Its 20 billion CFU dose of cultures provides a potent mix of Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus acidophilus and Bifidobacterium lactis.
  • LactoSpore®:
    A preparation of Bacillus coagulans, a probiotic bacteria found in your gut. We chose LactoSpore®’s preparation because it’s more stable than typical preparations, ensuring you get the best nutrition from a proven probiotic.

The Purpose

Pro Culture™ is the ultimate live culture supplement for professional athletes and elite trainers. As part of our Bulk™ PRO series of supplements, Pro Culture™ is produced to the highest standards using ingredients from industry-leading manufacturers, and every batch is tested for banned substances in an ISO 17025 accredited laboratory under the renowned Informed Sport programme. We also test every batch with a separate independent laboratory to verify its nutritional content, paying close attention to protein levels. If a batch doesn’t meet our rigorous standards, we reject it.
