Active, coenzyme form of vitamin B12
Methylcobalamin is the active form of vitamin B12. The liquid form helps your body absorb and use this essential vitamin fast and efficiently.†
B12 Liquid (Methylcobalamin) provides essential vitamin B12 to support red blood cell function, cardiovascular and neurologic health.† B12 is a nutrient needed to support many individuals, particularly those who avoid animal-based ingredients or have decreased levels of Intrinsic Factor due to increased age, poor diet, and/or certain medications.

VITAMIN B12 LIQUID
“PRL’s signature FermExcel-100 line is an industry first!”
- A Rich Source of Vitamin B12
- Methylated blood-circulating forms - methylcobalamin, adenosylcobalamin, and hydroxycobalamin
- Supports healthy energy levels, memory, mood, and cognitive health*
PRODUCT INFORMATION
Should you consider vitamin B12 as part of your dietary supplement regimen?
For most people, it may be difficult to get a sufficient amount of vitamin B12 from their diet because the sources of vitamin B12 are mostly found in high calorie foods (such as cheese and milk) which can lead to overweight and other health compromises. A lesser known natural source high in B12 is sprouts, but more difficult to obtain or eat in large amounts.
B12 as Methylcobalamin, Adenosylcobalamin and Hydroxycobalamin
Premier Research Labs’ B12-ND contains fully active co-enzymes of vitamin B12 that are rich in the desirable “blood circulating forms” of vitamin B-12 , namely, methylcobalamin, adenosylcobalamin and hydroxycobalamin. While the body is able to absorb food-source vitamin B12, it must further convert it to these three coenzyme forms in order for it to become metabolically active. When vitamin B12 is provided as methylcobalamin, it is already in the biologically active form and is able to yield optimal bioavailability and tissue retention. B12-ND is a probiotic-fermented, vitamin B12 formula that uses a unique probiotic culture which allows rapid oral delivery with superior bioenergetic properties. Our probiotic fermentation is cultured without the use of animal sources, making it suitable for vegetarians and vegans.
Brain and Nerve Health
The fully active co-enzymes of vitamin B12, specifically methylcobalamin, may support healthy brain cell activity including memory, mood and cognitive health.* In addition, methylcobalamin promotes neurological functions by encouraging protein synthesis to sustain healthy nerve cells.*
Energy Metabolism and Blood Health*
It is the coenzyme of vitamin B12, methylcobalamin, that synergizes with other B vitamins to support DNA and red blood cell health.* Through a series of biochemical reactions with homocysteine, these coenzyme factors of vitamin B12 are not only important to energy metabolism but critical to the methionine synthase pathway, supporting healthy homocysteine metabolism and S-adenosylmethionine (SAMe) production.* Methylcobalamin, the coenzyme form of vitamin B12, is the preferred form of B12 that is necessary for homocysteine modulation and the formation of methyl donors involved in cardiovascular function, sleep, blood cell formation, and nerve function.*
Probiotic-Cultured Delivery System
B-12ND is a revolutionary, highly absorbable delivery system made with our signature probiotic-cultured technology. Through a micro-cultured delivery system, it is the first B12 nutraceutical preparation designed to assure rapid absorption of these blood circulating forms of B-12. Even those with poor digestion can enjoy the full benefits of b 12’s highly bio-available co-enzyme B-12 liquid nutrients. No other form of B-12 can offer this type of bioavailability and quality.*
Support energy, memory, mood, cognitive health, homocysteine modulation, neurological function and whatever else life throws your way!* Premier Research Labs B-12 ND delivers unmatched results for when you need it most. Nothing works like B-12 ND!
RECOMMENDED USAGE
Take 1/4 teaspoon mixed in 4 oz. of water daily. Shake gently before use. Refrigerate after opening.

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.

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.
NeuroFactor® is a unique Coffee Fruit extract that has a profound impact on Brain Derived Neurotrophic Growth Factor (BDNF). BDNF also helps with cognition without being a stimulant.

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
Take 2 capsules daily, preferably 1 capsule twice a day with food, or as directed by a healthcare practitioner.
