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!

TURMERIC CAPSULES
- Premier quality Indian turmeric
- Supports liver and gastrointestinal health
- Contains naturally occurring curcuminoids with significant antioxidant capabilities
PRODUCT INFORMATION
Although turmeric has been traditionally used in cooking simply as a curry spice, numerous studies show that turmeric supports liver and gastrointestinal health. One of the main keys to turmeric’s nutritional benefits has been shown to be its high concentration of natural compounds known as curcuminoids. Curcuminoids are present as a naturally occurring component of turmeric and possess significant antioxidant capabilities. This provides free radical protection for liver and digestive health.
Premier Turmeric features organic, premier quality turmeric in its fullspectrum state. Thus, we do not specify a particular amount of curcumin in this product or assay for it. Concentration will vary per batch due to various factors, such as time of harvest. Our turmeric raw material is specifically selected due to its superior intrinsic bioenergetic properties as well as meeting our strict laboratory testing requirements.
We import our turmeric from Ayurvedic botanical growers in India where they have been naturally cultivating this nutritious root for centuries. Additionally, raw turmeric contains beneficial volatile oils. We encourage you to open a capsule for yourself to smell its rich aromatic, full-bodied aroma.
RECOMMENDED USAGE
Take 1 capsule, 3 times daily or as directed by a health professional.
