Nitric Oxide


(NOTE: NO = Nitric Oxide from now on)
DISCLAIMER: This thread does not talk about crazy supplements. its just some general knowledge that you should know to lead a healthy life, and is probably one of the softest of softmaxxing threads out there. much of the information listed in this thread should already be common knowledge.

Many of u guys might have at least heard the mention of nitric oxide the nitric oxide pathway, and that's because its the particular pathway thats mainly targeted by viagra. So already off the rip you can tell that influencing the nitric oxide pathway should be somehow related to blood vessels, thus impacting the eyes. This thread is also important for those who are using stimulants such as Adderall/Vyvanse, since your blood vessels are impacted heavily by these drugs.
So what is it?
Nitric oxide is a gas your body produces to tell blood vessels to relax and dilate. When NO signaling is good, blood moves through tiny capillaries, including the ones in your eyes and facial skin.
You ever realize how some people wake up and already, without any routine, their eyes are already clear, with a warm face and good toning before food/drinks? It should go without saying that circulation is indubitably one of the most important softmaxxes to just unlock your baseline level of looks. People who look good without doing anything have a fully functional vascular signaling profile, one which isn't shut down by stress and posture.
In the eye
Nitric oxide is a literal gas in your endothelium that tell blood vessels to stop being so rigid and to actually open for blood to go through. Nitric oxide has been scientifically shown to regulate the baseline level of blood flow in the choroid and retina, which should sound familiar if your eyes have a "dead" look.https://pubmed.ncbi.nlm.nih.gov/11587919/
Figure 1. Doesn't actually mean that much, just goes to show how many vessels are underneath your eyes, all of which are very small and delicate. Protect them at all costs
And no, it's not just the flow but actually also the regulation. nitric oxide is essential in something known as autoregulation, meaning that the eyes and face, making places on the body very sensitive to changes in pressure/posture and stress. If this system is already shit (waking up puffy or red), it takes half the day to normalize and look regular again - if it ever does lmfao https://pubmed.ncbi.nlm.nih.gov/17337232/
So this is why siting all day actually wrecks your face. You have no shear stress on the eyes, signal, dilation, and your vessels actually stay slightly constricted all the time. This reduces the overall flow in your body.
The goal isnt to actually how to increase NO, but actually how to force the body into certain states where producing NO should be the only response. This is why walking works, but not in the beta sense of just walking 10k steps, but actually its more about the sustained rhythm of movement. When you walk for around 10-15 minutes before lifting, you're just pushing blood through larger vascular beds in a non-chaotic way, with shear stress telling the endothelium to release NO.
1. Breathing
This actually matters a bit, nasal breathing is mechanical. The crazy part is the nasal epithelium itself literally produces nitric oxide, and exhaled NO is actually measured as a clinical physiological marker. https://pubmed.ncbi.nlm.nih.gov/12556406/Many of you guys know already that mouth breathing is bad, but this actually cements it scientifically as something that you should not do. By breathing through your mouth, you're actually just skipping an entire NO related pathway that makes the vessels stay rigid, preventing proper flow.
SIDE NOTE: Humming
LMFAO For once this isnt actually cope. Albeit weird, I'm not telling you to start maasai jumping or some shit. Humming actually does play a role in NO. Nasal and sinus NO production actually spikes during humming due to oscillatory airflow (basically the vibrations that you make during humming influence the air that your sinuses get). You don't have to go full berserk monk mode, u actually just have to have a few minutes of low frequency (low pitch) humming. Make sure to really feel the vibrations through the nose, do it before sleep or after waking and it should theoretically stimulate NO. It doesn't hurt to try.
2. Diet
Honestly not that important. Just eat your vegetables like arugula or some shit, since the nitrates from your diet converts to nitric oxide. many of you guys i assume already eat enough vegetables3. Posture
Gets kind of schizo, but should be obvious if you think about it for a little more than 5 seconds. Your face is the only body part that is above the heart. Microvascular perfusion is very sensitive to pressure, so if you wake up folded like a pretzel with your neck cranked forward and immediately wake up to be slumped again over a phone, your blood distribution will be bad. This is given, and it shouldn't take this thread to tell you that fixing your posture is much better for you than just circulation.EXOGENOUS METHODS
Ok here's what you guys have been waiting for. Just open up an amazon tab and start ordering shit but this doesn't mean that you should just ignore the previous methods. Supplements just tilt existing pathways, so if the base system is dead, then all the money you spend is just released via piss straight into your toilet where you can then flush your wallet goodbye1. L-arginine & L-citrulline.
Somebody at some point in your career have told you to take these probably without understanding what it actually does, but the eNOS literally uses L-arginine as a substrate. Citrulline works upstream by recycling back into arginine in the kidneys, and is a very basic and established pathway.
NOTE: Taking these while living sedentary have literally no effect. The enzyme still needs shear stress in order to have an effect, so you still have to be active.
Figure 2, The red arrows mean inhibition, for those who do not know. Smooth muscles, aka the muscles that line your arteries, is shown to be enabled by L arginine and L citrulline working in harmony. Pretty beautiful side effects are also noted, which are collagen synthesis and cell proliferation, all relatively beneficial.
2. Polyphenols (esp. cocoa flavanols)
It should be noted that these don't actually make NO, they are just responsible in the pathway that produces it. Nitric oxide is very chemically unstable, with oxidation "killing" it very fast. Cocoa flavanols in specific have been shown to improve endothelial function and dilation of flow mediators. The longer than NO sticks around in your body, the longer than vessels stay open. This is especially helpful for those who are chronically stressed or those who are prescribed (or abuse) stimulants. Without antioxidants, NO is neutralized before it can actually do anything. This is especially important for adderall heads.
Figure 3. Couldn't find any other graph that shows how polyphenols interact with NO, but this is just a graph that shows the exact pathway in how polyphenols produce NO and thus lead to vasodilation. Keep in mind that there are many more functions to NO, which not only enables cGMP.
3. Vitamin C
Sounds boring, is boring/ Vitamin C stablizes something known as tetrahydrobiopterine (BH4), which is a cofactor of eNOS, meaning that eNOS essentially needs it to function properly. When BH4 is low, eNOS is uncoupled and produces a lot of oxidative shit instead of nitric oxide. This literally means that without sufficient vitamin C (which is more prevalent than you may think in the general population), your NO deadass turns evil and harms you. https://pubmed.ncbi.nlm.nih.gov/33940170/
Figure 4. Here you can see how both the vitamin c and dietary nitrate inputs affect EF. Also includes L-arginine. Oh yeah everythings coming together
IMPORTANT FINAL NOTE: THINGS YOU SHOULD AVOID
Avoid:
- Caffiene
- Nicotine
- Slamming supplements - You have to make a clear distinction between inflammatory NO (iNOS) and eNOS (good). Doing so many supplements can push you towards oxidative stress instead of the goal, which is better circulation. NO is a very double edged molecule since it serves many functions, and having too much because of exogenous impact will negatively impact you.
