How It Works
B vitamins are essential cofactors involved in energy production, methylation, neurotransmitter synthesis, red blood cell formation, and the metabolism of carbohydrates, fats, and proteins. Because they are water-soluble, regular intake is important for maintaining adequate nutritional support.
Thera-B™ provides high-potency amounts of essential B vitamins together with related nutrients such as choline and inositol. The formula is especially focused on bioavailability by including Metafolin® L-5-MTHF, a bioactive folate form, and methylcobalamin, a bioavailable form of vitamin B12.
Activated folate and methylcobalamin support methylation pathways that are important for cardiovascular wellness, nervous system function, and normal homocysteine metabolism. The broader B-complex also supports daily energy production, mood, memory, stress-related nutrient needs, and overall metabolic balance.
This makes Thera-B™ a practical option for adults looking for a high-potency B-complex supplement, activated folate and methyl B12 formula, energy metabolism support, methylation support, or vegan B vitamin complex.
Who Is It For?
Thera-B™ may be suitable for adults seeking daily support for energy, metabolism, mood, memory, nervous system health, cardiovascular wellness, methylation, and general nutritional balance. It may be especially useful for people who prefer a B-complex with activated folate and methylcobalamin rather than standard folic acid and cyanocobalamin.
Suggested Use
Adults: Take 2 capsules daily with food, or as directed by a healthcare professional.
Children: Use only as directed by a healthcare professional.

How It Works
B vitamins are water-soluble nutrients used throughout the body for energy production, nervous system function, methylation, detoxification pathways, cardiovascular support, and healthy stress response. Because water-soluble B vitamins are not stored in large amounts, the body benefits from a steady daily supply.
Activated B with SRT® uses active or body-ready forms of key B vitamins. This includes P5P vitamin B6, riboflavin-5-phosphate, Quatrefolic® methylfolate, and MecobalActive® methylcobalamin B12. These forms are designed to be readily used by the body without relying heavily on conversion from less active forms.
The formula also includes choline, inositol, and PABA to broaden support for methylation, cell membranes, nervous system signaling, and overall B-complex function.
The key feature is Sustained Release Technology. Instead of delivering a large amount of B vitamins all at once, the tablet is designed to provide gradual support over time. This makes it a practical choice for people looking for steady daily energy support, mental clarity, stress resilience, and methylation support.
Suggested Use
As a nutritional supplement, take 1 tablet daily. Or use as directed by your healthcare professional.

It may come naturally to some, but most of us can do well with a boost. AdultFocus from Advanced Nutrition by Zahler is formulated to provide adults with the power to perform and ability to achieve.
ALL ABOUT ADULTS
Sure, adults are past the teenage angst, but many can still greatly benefit from an extra boost. While adult brains are fully developed, they can still use boosters to help with focused tasks and responsibilities, especially if this is something they struggled with in their earlier years. Maturity that comes with adulthood allows for the choice to supplement with that which provides the variables for success.
Aging is a good thing; we all wait to get to the stage where we can look back at our accomplishments and share memories. However, in many cases, the adult brain can use a boost to work to its fullest. Our lives are very stressful, filled with family obligations, work and social demands. Yet, there’s only so much a brain can handle. Whether it is the attention span, recall or just mental sharpness you are looking to boost, AdultFocus contains potent ingredients beneficial for optimal brain function.
AdultFocus from Advanced Nutrition by Zahler is a unique supplement designed to provide adults with the nutrients and herbs most beneficial for brain health and function. Many adults struggle with inattention, cognitive processing and focusing.
The natural ingredients in AdultFocus boost the brain when it comes to focus, concentration, sharpness and more. These ingredients target specific issues.
WHAT’S INCLUDED:
SUNTHEANINE®, isolated from green tea, helps support a calm and focused state without affecting alertness.
Phosphatidylserine helps reduce levels of cortisol, the stress hormone. Citicoline is important in the production of neurotransmitters and helps support active cognition.

Product FAQs
What is the main difference between the TeenFocus and AdultFocus supplements?
Both the TeenFocus and AdultFocus boost brain function and promote mental focus and concentration. The TeenFocus also specifically supports a calm and positive mood since this is one of the primary reasons why teenagers would have difficulty focusing. The AdultFocus better supports memory and concentration in the adult brain.
Should I take AdultFocus only on the days I need to focus or should I take it every day?
Since this is a natural product and it takes time to see full results, this product should be taken twice a day every day, regardless of how much you need to focus at the moment.
Suggested use
