Natural Sleep/Wake Cycle Support
Benefits and Features
Melatonin is a hormone produced by the pineal gland in the brain, which regulates the body's sleep/wake cycle†
- Promotes regulation of the body's circadian rhythm, hormone secretions, and sleep patterns.†
- Helps facilitate the onset of sleep as well as sleep efficiency.†
Detail Overview
Melatonin's primary role is the regulation of the body's circadian rhythm, endocrine secretions, and sleep patterns. Studies indicate that it facilitates the onset of sleep, as well as sleep efficiency.1 Supplementing with melatonin can help support your body's declining production that may occur as you age.† This sustained release formula releases slowly over several hours to help support blood levels for a longer period of time.†

Supports Healthy Estrogen Metabolism for Both Men and Women
Benefits and Features
Indole compounds like those in cruciferous vegetables help protect tissues such as the breast, cervix, and prostate against the effects of undesirable estrogen metabolites.†
Detail Overview
Indole compounds favorably influence steroid hormone metabolism and help rebalance estrogen in favor of 2-hydroxyestrone, a protective estrogen metabolite.† Dietary indoles also stimulate liver detoxification enzymes, protect DNA, and regulate cell cycle progression.† Indole-3-carbinol (I3C), the most prominent dietary indole, readily breaks down in the presence of stomach acid into diindolylmethane (DIM) and other associated indole compounds that are subsequently absorbed. Indole Forté™ contains I3C, DIM, and other indoles for broad protection.
| Serving Size 1 Capsule | ||
| Amount Per Capsule | % Daily Value | |
|---|---|---|
| Total Dietary Indoles Proprietary blend containing indole-3-carbinol and diindolylmethane |

References: undefined
Indole Forté™ contains a mixture of two important dietary indoles, indole-3-carbinol (I3C) and diindolylmethane (DIM). Since I3C undergoes biochemical transformation to related indole metabolites, broad-spectrum indoles may be present upon absorption.
Suggested Use
Adults: 1 capsule, 1 to 2 times daily or as directed by a healthcare professional.
Allergy Statement
Made without common allergens: milk/casein, eggs, fish, shellfish, tree nuts, peanuts, wheat, gluten, soybeans, and sesame. Non-GMO Vegan, No synthetic colors or flavors.

A targeted probiotic blend clinically demonstrated to support mood.
Benefits and Features
- Powered by Ecologic BARRIER, a 5B CFU blend of 9 probiotic strains
- Protected by PROBIOACT® Technology for optimal efficacy and shelf-stability
- Hypoallergenic, non-GMO powder in single-serving sachets
Clinically shown to support positive mood by influencing the gut-brain axis through the microbiome.†
Detail Overview
Target gb-X™ is a probiotic supplement specifically designed to support positive mood by influencing the gut-brain axis through the microbiome. It is powered by Ecologic BARRIER, a 5B CFU blend of 9 probiotic strains, that has been clinically shown to decrease overall cognitive reactivity to sad mood, rumination, negative thoughts, and aggressive thoughts.1 Heightened cognitive reactivity to sad mood is an established risk factor for more serious mood alterations in otherwise healthy individuals and is therefore considered an important target for interventions.
Target gb-X™ Mechanism
Target gb-X™ with Ecologic BARRIER was specifically designed to influence the gut-brain axis through defined mechanisms including strengthening of the gut barrier function, modulation of cytokines and inflammatory response, production of potentially neuroprotective metabolites, and HPA regulation. Preclinical research emphasized a pronounced shift away from macrophage-produced cytokines to T-lymphocyte-produced cytokines, a reduction in circulating lipopolysaccharide endotoxins, and a marked reduction in transcription of hippocampal genes related to HPA regulation.2
Probiotics and the Gut-Brain Axis
The gut-brain axis refers to the bidirectional communication network between the central and autonomic nervous systems and the intestines. Gut-brain communications are mediated by the immune system, endocrine connections such as the hypothalamic-pituitary-adrenal (HPA) axis, and neural pathways involving the enteric nervous system. The gut microbiota is now known to play a pivotal role in gut-brain communications. It is a complex interaction whereas the microbiota engages locally with intestinal cells as well as communicating directly with the central nervous system through neuroendocrine, immune, and metabolic pathways.3 Research into gut-brain mechanisms is rapidly expanding our understanding and serves to inform the development of targeted probiotic formulations.
