Natren's Guide to Probiotics for the Whole Family:

New to Probiotics - Start Here:
Natren's Life Start line of probiotics offers an ideal starting place for just about anyone, regardless of age, sex, or sensitivities. The Life Start line is offered in 3 versions, they all feature the same beneficial bacteria (Bifidobacterium infantis NLS super strain) but each are grown in unique ways.  We are the only probiotic company in the world that manufactures and sells this unique probiotic bacteria B. infantis NLS super strain. (1) Life Start - we'll refer to this as original; (2) Life Start 2; and (3) Life Start Vegan.

The key differences between the Life Start options are the growth medium (used to grow the bacteria) and the delivery method (capsules vs. loose powders):

(Click Image to Order)
Life Start
Cow's Milk Loose Powder (1.25, 2.5, and 4.5 oz options.)

Excellent for all who are dairy tolerant.


Great for families, larger size available.

Life Start 2
Goat's Milk

Capsules (60, 90 count.)


Loose Powder (2.5 oz or 4.5 oz options.)

Adults tend to prefer ease of capsules


Great for families, larger size options.

Life Start Vegan
Organic Brown Rice Loose Powder (1.25 oz.)

Great for anyone with dairy allergies

Adults tend to prefer Life Start 2 because it's available in a convenient capsule form. On the other hand, Mom's with little ones tend to prefer any of the powdered options because the powders are easy to stir into breast milk, smoothies, yogurt, applesauce, etc. for little ones to consume. Since bacteria thrive so well on a dairy base we always suggest using our dairy based options if dairy tolerance is not an issue for you, Life Start original. However, if you have issues with Cow's Milk you may be surprised that you do just fine on the gentle Goat's Milk formula (Life Start 2). If you have a known dairy intolerance, stick with Life Start Vegan. All of these options are Gluten Free, Soy Free, contain no GMOs or FOS and are the only probiotic products that strictly adhere to the probiotic labeling standards.

Sensitive Gut?

Anyone with a sensitive gut should order a powdered version because these are easiest to scale up and down to meet the needs of the individual. We've had people start with as little as 1/16th of a teaspoon and gradually work up to standard serving size of ¼ - ½ of a teaspoon.

Clinical Trial Support

The probiotic bacteria used in all of our Life Start line of supplements is supported by a randomized, human clinical trial that was published in The Journal of Clinical Gastroenterology in 2013.1 The three week trial tested our B. infantis NLS super strain in people with specific gut issues and reported the following results:

  • Scientifically significant improvement in two symptoms and almost significant improvement in a third symptom as reported by the Gastrointestinal Syndrome Rating Scale (GSRS) questionnaire:
    • Indigestion : significant improvement
    • Constipation : significant improvement
    • Reflux : approaching significant improvement
  • More than 70% of participants reported improvements in regards to distension, bloating and gas in the probiotic group versus 30% in the placebo group.
  • The probiotic group also showed promising reductions in important immune system changes associated with gut disturbances.
  • Following completion of the clinical trial scientists later published additional results from biopsies in a journal supplement outlining additional results and indicating Life Start probiotics may play an important role in improving small intestine dysbiosis.2
