The Acid Proof Deep Release Probiotic Supplement

What is Theralac?

Probiotics such as Lactobacillus acidophilus and Bifidobacterium lactis are beneficial bacteria that colonize the human intestinal tract. Species of Bifidobacteria colonize the large intestine while Lactobacillus species colonize the small intestine. Theralac is a new, highly effective probiotic that replenishes these beneficial bacteria with a MINIMUM 30 billion CFU of five well researched probiotic strains. Theralac promotes a healthy soft-lining (wall) in the intestinal tract which results in improved digestion, regularity and nutrient absorption.

Theralac is the most effective probiotic supplement because its patented acid-proof formulation protects sensitive probiotic bacteria as they pass through the acidic stomach; this allows them to enter the intestinal tract unharmed at full strength. The patented formulation, utilizing sodium alginate and grape skin extract, forms a buffered gel in the stomach. This protects the probiotic microorganisms. This is a significant improvement over enteric coated probiotics. Once in the intestinal tract, Theralac's five probiotics are stimulated into action by its two prebiotics (LactoStim and Lactoferrin -- patent pending) to give you maximum probiotic benefit. It's called 5 + 2 Biotherapy and is only available in Theralac.

THERALAC® does not contain: Yeast, Eggs, Corn, Soy Protein, Gluten, Wheat, Salt, or Beef Products. The Lactoferrin in THERALAC is a purified protein derived from milk and does not generally cause allergic reactions in persons sensitive to milk or dairy products. Microcrystalline cellulose, silica and magnesium stearate (vegetable source) are inert excipient ingredients. Consult with your doctor before taking THERALAC if you have specific allergic sensitivities.

Theralac's 30 billion CFU/capsule are guaranteed through expiration. Theralac is a probiotic supplement that truly works!

Another First from Theralac ®

One of the major functions of a probiotic supplement is to produce lactic acid – this is referred to as ACTIVITY. ACTIVITY is the work probiotics do and goes beyond the CFU analysis which is important but only half the story. ACTIVITY is the other half of the story. Does your brand report ACTIVITY?

The #1 “molecular effect” of Theralac® is the production of lactic acid deep in the GI Tract; and with Theralac's patented delivery system and LactoStim™ prebiotic stimulation – it produces more lactic acid than any other probiotic. For example, 1% lactic acid production in 24 hours is considered a good result. Theralac® produces 1.3% to 1.6% in 12 hours. This test was performed by an independent laboratory, Minnesota Valley Testing Lab, in New Ulm, MN – results available upon request.

Theralac ® probiotics are the most cost effective probiotic supplements on the market today.

For probiotic supplements to be of maximum value they must work FAST. Theralac works fast. The cost of the bottle does not relate to the cost of using the product on a weekly basis. At Theralac's maintenance dose of two capsules per week, the cost is less that $3.00 per week. . . That is Value! Theralac® guarantees 30 billion CFU at expiration, not time of manufacture.

One bottle lasts 10 weeks on the standard dose program: one capsule daily for 2 weeks followed by 2 capsules per week thereafter. One bottle lasts for 15 weeks on the maintenance dose of 2 capsule per week.
