BioSpora™ is a powerful, hypoallergenic blend of genetically certified Bacillus coagulans and B. subtilis species formulated to provide unique probiotic support of healthy gastrointestinal and immune function.† Spore-forming bacilli have often been referred to as soil-based microorganisms because of their ubiquitous presence in the earth. When isolated from the human GI tract, spore-forming bacilli have long been thought to be transient bacteria. However, current research shows that Bacillus species are present in the GI tract in numbers higher than can be explained by ingestion alone. Germination of Bacillus spores within the human small intestine and transient colonization is now thought to be part of the normal life cycle of human-associated Bacillus species providing specific stimuli for healthy GI and immune system development and function. Each capsule of BioSpora™ supplies a total of 2 billion CFUs of B. coagulans and B. subtilis spores positively identified through independent 16S ribosomal RNA gene sequencing. The spores are resistant to extremes of heat, ultraviolet radiation, solvents, hydrogen peroxide, and enzymes. The spores withstand stomach acid and germinate in the small intestine within 6 hours of ingestion. Ingested B. coagulans and B. subtilis reside in the human GI tract for up to 7 days following consumption. BioSpora™ is recommended for enhanced support of normal GI and immune function.† It is certified free of casein, gluten, and soy. BioSpora™ does not require refrigeration.
As a dietary supplement take one capsule daily with food or as directed by a healthcare practitioner. Capsules may be pulled apart and nutrients taken separately.

Specialized digestive enzyme blend specific for gluten, casein, and other small proteins
Benefits and Features
A proprietary blend of microbial enzymes, SerenAid® is specifically formulated to assist in breaking down a broad range of plant and animal proteins, including casein (milk and dairy products), gluten (wheat, rye, oats, barley, and other grains), and soy proteins. The inclusion of Exorphinase® differentiates SerenAid® from other digestive enzyme formulas. This proprietary, high-activity enzyme blend of peptidase and protease with dipeptidyl peptidase IV (DPP-IV) activity can assist in hydrolyzing small protein peptides, including casomorphins and gluteomorphins that can adversely affect the central nervous system in some individuals.† The enzymes in this formulation are pH-stable, demonstrating activity over a wide range of pH conditions (pH of 2 to 12).
SerenAid® Attributes
- First fungal-based enzyme formulation to offer dipeptidyl peptidase IV (DPP-IV) activity formulated to support the unique proteolytic needs of children on the spectrum†
- High serine proteinase DPP-IV activity, to cleave the post-proline bonds and prolyl bonds near the N-terminus of proteins and peptides†
- Post-proline and prolyl bond cleavage supports proteolysis of casein, gluten, and their exorphin peptides, casomorphins, and gluteomorphins†
- Proprietary, patented‡‡ combination of peptidase and protease enzymes with DPP-IV activity to support hydrolysis of exorphin (opiate-acting) peptides†
- ‡‡US Patents 6,808,708, 6,821,514, 6,251,391, 6,447,772.

Versatile nutrient supports mood regulation, joints, and liver function†
Benefits and Features
- Promotes healthy mood, cognition, and emotional wellbeing†
- Major source of methyl groups used by the brain in the synthesis of neurotransmitters†
- Supports joint comfort and mobility, cellular detoxification, and liver function†
Supports numerous energy-requiring processes within your body, promoting healthy mood, cognition, and emotional well-being.† In numerous clinical studies, SAMe has also been shown to support bone and joint health, liver detoxification, and healthy cell membranes.†
Detail Overview
SAMe (S-adenosylmethionine) is a natural compound made in the body from the essential amino acid L-methionine. It is involved in a number of body processes, including membrane function, neurotransmission, liver detoxification, and bone and joint health.† Although SAMe can be synthesized in the body, it is dependent upon the presence of sufficient levels of other nutrients including methionine, folic acid, and vitamin B12. Dietary supplementation of SAMe is an effective way to support optimal levels of this compound.
Low levels of SAMe may result in lowered serotonin levels, a brain chemical that supports mood and emotional well-being. SAMe is also required for nerve regeneration. SAMe has been shown in numerous controlled clinical trials to support a healthy mood.† SAMe has been shown in animal studies to support cartilage growth and repair. In numerous human clinical trials, SAMe has demonstrated benefits for joint structure and function comparable or superior to those of other sulfur-containing nutrients such as glucosamine sulfate, chondroitin sulfate, and MSM.† Research suggests that the mechanism of action behind this benefit may be due to this compound’s support of cartilage formation.†
