New and improved vegan formulation Please note, the formulation for Pro 5 has been improved and is now suitable for vegans. Our previous formulation contained vitamin D3, which is not suitable for vegans. We have replaced vitamin D with vitamin B12, which still provides support to your immune health and is now suitable for those following a vegan diet. What is Pro 5? It’s a formulation that combines five billion live cultures with added vitamin B12 to support your immune system. This multi-strain formula contains three carefully selected and well-researched bacteria strains, including lactobacillus acidophilus, bifidobacterium lactis and lactobacillus paracasei. Why is ours better? Unlike many live culture products, Pro 5 is lactose-free, making it suitable for those who have a reduced ability to digest products containing cow’s milk. What’s more, our vegan capsules contain tough bacteria strains that have a long shelf life. Finally, vitamin B12 has been added for its benefits to supporting your immune health, and also has proven benefits in reducing tiredness and fatigue and normal energy-yielding metabolism.
