Nicotinamide Adenine Dinucleotide (NAD+) Peptide

Nicotinamide Adenine Dinucleotide (NAD+) is an oxidized form of NADH (Nicotinamide Adenine Dinucleotide Hydroxide). NAD+ is a component of the Electron Transport Chain (ETC), had has been suggested by researchers to act in carrying electrons within and without the cell body. The peptide has also been posited to act as a mediator for various physiological processes, such as post-translational modification of the proteins and activation/deactivation of some enzymes. It may be a critical component in maintaining cell-to-cell communication. The neurons present in blood vessels, intestines, and bladder, appear to release endogenously produced NAD+, which appears to act as an extracellular signaling molecule and bioregulator.

NAD+ Research

NAD+ and Cell Aging
Mitochondria serve as a platform for primary metabolic functions such as intracellular signaling and regulation of innate immunity. These processes appear directly affected by mitochondrial senescence and ultimately alter cellular metabolism, inflammation, and even stem cell activity.[1] These altogether may reduce the pace of tissue repair following damage. This illustrates the extent to which mitochondria are involved in age-related tissue and organ function decline. Researchers consider that in the course of manipulating mitochondrial activity, they may potentially slow, cease, or even reverse the process of cellular aging. A deficiency of NAD+ in the cell appears to induce a pseudo-hypoxic state which interrupts signaling within the nucleus. Studies have suggested that NAD+ supplementation may help in reversing at least some of the age-related decline in the function of mitochondria.[2] The scientists concluded that “raising NAD+ levels in old mice restores mitochondrial function to that of a young mouse in a SIRT1-dependent manner.” The mechanism underlying this property appears to involve the activation of the SIRT 1 function, whereby a gene encodes an enzyme called Sirtuin-1 (NAD+ dependent Deacetylase Sirtuin-1). Sirtuin-1 then may regulate the mediators involved in metabolism, inflammation, and the longevity of cells.[3]

NAD+ and Muscle Function
Natural decline in muscle function is associated with mitochondrial senescence. Scientists consider that the decline occurs in two steps. The first, to some extent reversible, involves declined expression of mitochondrial genes. These genes appear to be responsible for oxidative phosphorylation (the process by which mitochondria produce energy). The second, irreversible, consists of a decline in genes responsible for oxidative phosphorylation in the nucleus. Mice experiments have reported an apparent step 1 reversal with the exposure of additional NAD+ before the cell progresses to step 2.[4] The mechanism behind this intervention in mitochondrial aging may involve stabilizing the activity of Peroxisome Proliferator-activated Receptor Gamma Co-activator 1-alpha (PGC-1-alpha). Studies have suggested that the effect mentioned above produced in the mitochondria may be similar to exercise on the mitochondria of skeletal muscles.[5]

NAD+ and Neurodegenerative Diseases
NAD+ is a cofactor that may exert a possible neuroprotective action.[6] It has been posited to do so via the improvement of mitochondrial function and reducing the production of Reactive Oxidative Stress (ROS). ROS is responsible for inflammatory changes associated with injury and degenerative changes associated with cell aging. This association provides its basis for certain neurodegenerative diseases such as Alzheimer’s, Huntington’s, and Parkinson’s disease. Research conducted on mice suggested the potential for NAD+ to protect against progressive motor deficits and the death of dopamine-producing cells in the substantia nigra.[7] According to the researchers “These results add credence to the beneficial role of NAD against parkinsonian neurodegeneration in mouse models of PD, provide evidence for the potential of NAD for the prevention of PD, and suggest that NAD prevents pathological changes in PD via decreasing mitochondrial dysfunctions.” The research findings implied that although NAD+ doesn’t appear to alleviate the symptoms, it may slow the progression if not entirely prevent the development of Parkinson’s disease.

NAD+ and Inflammation
NAMPT is an enzyme that is associated with inflammation. It appears over-expressed in certain types of cancers. An increase in the levels of NAMPT appears to correlate to NAD+ levels, and vice versa.[8] The NAMPT-associated inflammation appears to occur in cancers, obesity, type 2 diabetes, and nonalcoholic fatty liver disease. NAMPT may be a potent activator of inflammation whose levels may decrease dramatically following the introduction of NAD+.

NAD+ and Addiction
Addiction has been suggested to be associated with a decline in the levels of NAD+. Addiction typically leads to significant nutritional deficiencies and cognitive deterioration. Supplementation with NAD+ may help overcome these changes and can be helpful in various addiction disorders as seen in ethanol-exposed murine models, who reportedly exhibited greater recovery rates than control models.

    Happy paying their prices, wish they did come up with some more bundle options! That could be interesting!

  9. Brooke Bowden

    Fast, well run, and orgaized team they got here!

  10. Cody Davis

    products speak for themselves wish they stocked up more frequently

  11. Parker Findlay

    It’s always unfortunate when your orders come in poor condtioned or broken. That was the case for me this morning. Showed up to work and saw my package had been delovered from Biotech. Great! However, once I looked inside I noticed alot of the vials and containers were broken even though there is a Fragile sticker that the carriers can’t miss. It has happened before so I already knew it would get handled right away. My personal go to is Taylor so I emailed them right away and they were abel to rush me a new order. I got a confirmation numer that it would be delivered soon so fingers crossed it gets here in perfect condition!

  12. Benji Hyrum

    They are consistent with product quality, have had no breaks or damages so far and I have been a customer since April.

  13. Dara Elizabeth

    So far, so good with them

  14. Raven Martinez

    Taylor is always on top of their game, super quick on fixing issues and just helping out. Knows a lot about the company and the ins and out.

  15. brian geralds

    Service is great, placed my order before 2 and was informed my order was shipped and would be at my lab that same evening!

  16. Collin Nicoles

    My research peptides have always come from Biotech Peptides, and I’ve never had anything but good things to say about them and their products. Been with them for over a year now.

  17. Adam bailey

    To obtain peptides, this is one of the best locations to get them! There are also a few goods for sale from time to time. The best part is that they provide discounts for large purchases.

  18. Omar Nobel

    Was worried my vials would come in broken as it seems to happen a bit but glad to report my did not!

  19. Kalee Pierce

    Been searching for NAD for a while now. This is the best price I found

  20. Corey Abowd

    You guys are my go-to peptide supplier of all times. I love everything about you, from peptides, to CS, deals and offers, everything fits

  21. Ron Aguirre

    I recommended this to all of my fellow coworkers, They just deliver amazing peptides every time

  22. Sam Dunley

    They are very straightforward with how they work and deal with issues. Work gets down quick. I recommend E-mailing rather tan calling when issues do arise though. Much faster and easy to document too.

  23. Oleg Ivanova

    Esta es la mejor compañía de péptidos que he conocido.

  24. DJ Morataya

    No issues in slightest for the past 2 years i have been buying peptides from them.

  25. Austin Westrup

    Straightforward transaction okay prices. If they have sales buy buy buy.
