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!

The perfect casual layer—unbelievably soft!
Size: Large, Color: Burgundy
I am seriously impressed with this hoodie. It’s made from a lightweight jersey material that feels just like a broken-in, high-quality t-shirt. It’s perfect for those transitional weather days when a heavy fleece hoodie would be too warm, or for just lounging around the house. The fit is spot on—not too baggy but with enough room to move comfortably. It washes really well without shrinking or losing its shape. For the price, you absolutely cannot beat the value. I'll definitely be buying a few more colors!

The Perfect Hoodie for Warm Weather Comfort
Size: XX-Large, Color: Black
I've been on the lookout for something exactly like this... a hoodie with the look and feel of a sweatshirt, but without all that heavy fleece that can become uncomfortable when temperatures rise. This Amazon Essentials Lightweight Jersey Pullover Hoodie turned out to be just the solution I needed. Right out of the package, I noticed the material felt soft and airy, like a premium-quality T-shirt rather than a traditional hoodie. The lightweight fabric hits just the right balance: thin enough to remain cool and breathable, yet substantial enough to give you that hoodie vibe you're after. This makes it especially great when the weather is too warm for your thicker hoodies but still a bit too breezy for just a tee. The fit is exactly what I was hoping for... comfortable without being baggy, and relaxed enough to allow easy movement. It drapes nicely, so it never looks awkward or ill-fitting. The hood itself is perfectly sized—not overly bulky, but still practical if you need a bit of coverage. No shrinkage when washed and didn't fade. I've found this hoodie to be ideal for casual days around town, lounging, or even traveling. It layers well, making it versatile for spring, early summer evenings, or warmer fall days. If you're looking for something comfortable, lightweight, and stylish enough to pull off the hoodie look in warmer weather, this is absolutely worth picking up.

My new favorite hoodie!
Size: XX-Large, Color: Charcoal Heather
I love this, this is my new go-to hoodie! It's very soft and breathable, it's roomy and comfortable, and it's not too heavy. I've washed it a few times and it's held up well. For the price, you really can't go wrong. I'll probably end up buying a couple more colors.

Sleeves are too short
Size: Large, Color: Black
Good quality about as thick as heavy t shirt. The only issue is the sleeves are a tad short which is a bit disappointing. Not sure I will buy this again. I’m 5-7 175 and ordered a large and it fits well. Just a smidge oversized like I prefer.

Lightweight and comfortable
Size: X-Large, Color: Black
Lightweight yet warm. Bought an XL for my husband who is 6’ 2”, weighs about 180 lbs, and has long arms. Fits a bit loose but not too big but have to size up so the length in the arms fit better. He runs warm so dislikes anything that makes him hot, so this material was great. Did not discolor or shrink in the wash, which was a bonus.
