Natren Healthy Start System® The Healthy Start System® is an easy to use three-step probiotic supplement system for optimal overall and digestive health. This custom probiotic system is a great starter and maintenance program to provide helpful levels of beneficial bacteria throughout the gastrointestinal tract. Some bacteria are naturally competitive, competing with their neighbors for space and resources. So Natren keeps each bacteria species in the Healthy Start System® in separate bottles to guarantee our probiotic product potency. We are the only custom probiotic manufacturer and distributor to keep the strains separate for your benefit. This method allows you to experiment and decide which probiotic supplement program is best for you. Taking probiotic supplements can be like going to the gym - a work out program that benefits one individual may not have the same results for a different individual. This kit allows you to mix and match, layer together, and experiment with different amounts to find the most beneficial effect for your digestive health. Each kit is either a 30-day supply, or our new 60-capsule (60-day) Family Size, and includes one bottle each of: Megadophilus® provides the "good bacteria" Lactobacillus acidophilus DDS-1 (in dairy based powder) or NAS super strain (in dairy free vegetarian/vegan capsules), 2 billion colony forming units (cfu) per capsule or 1/2 tsp.

A note about dairy based probiotics: Dairy milk is one of the original foods that these bacteria thrive on, which is why they are called Lacto bacilli, meaning milk bacteria. [Ayurveda, a Hindu system of traditional medicine used in India for over 5000 years, is devoted to using dairy products, as milk is considered the pure love of the cow for her calf. Ayurvedic doctors and pharmacists highly recommend dairy products to their patients.] Natren is one of the few custom probiotic manufacturers to still use dairy as a growth medium for beneficial bacteria.
