Have you ever been in the middle of a lift when you can just feel the blood start to course through your veins?

Your power skyrockets and you feel like you're absolutely destroying your workout? That 'pump' that bodybuilders chase after is generally the result of increased levels of nitric oxide (NO), a signaling molecule that plays a major role in blood vessel health.

It serves to dilate blood vessels and allow greater blood flow for better oxygen and nutrient delivery, hence the notorious pump we get from NO-boosting supplements.

So, if you're looking for a natural way to elevate your workouts to achieve more energy, more strength, and a bigger and better muscle pump, a nitric oxide boosting supplement is right up your alley—and we've got you covered for what to choose.

We're breaking down what you need to know about nitric oxide supplements and why this one needs to be in your training stack.

What Is Nitric Oxide?

For anyone in the fitness world, nitric oxide is gold. It's what gives the 'pump' that everyone chases that can turbocharge your workout like no tomorrow. While we typically think of nitric oxide coming from something like a pre-workout, it's actually a compound produced in the body.

It's a small, simple, and highly toxic compound that seems like a biological jack-of-all-trades, but is incredibly noxious due to the free radical stricture that makes it highly chemically reactive 1.

Although it's such a reactive compound, it's critical for the function of all mammals. It's quite possibly one of the most important messenger molecules that's involved in immune responses against tumor cells and bacteria, along with allowing neurotransmitters to relax blood vessels for better blood flow.

It's synthesized from its precursor amino acid L-arginine and participates in virtually all cellular and organ functions in the body, including regulating blood pressure, transmitting signals between neurons and suppressing and eliminating pathogens 2.

While typically we think of "more is better" in the bodybuilding world, excess NO can actually damage host cells, causing neurotoxicity. In the vasculature, however, it serves to regulate vascular tone and blood flow by activating soluble guanylate cyclase (sGC) in the vascular smooth muscle 3.

This aspect of NO is why athletes and bodybuilders love the stuff.

Benefits Of Nitric Oxide Supplements

Boosts the "pump"

Nitric oxide is a gas that's produced by the lining of blood vessels (endothelium) to increase vasodilation and promote better blood flow.

Because blood carries oxygen and nutrients to active muscles, increasing blood flow due to consumption of nitric oxide supplements may help to extend work capacity and may enhance recovery. But it's also about that "pump", which is what people refer to when muscles increase in size from literally being engorged with blood.

Research shows that NO regulates the degree of contraction of vascular smooth muscle cells by triggering soluble guanylyl cyclase (sGC) to produce cyclic guanosine monophosphate (cGMP) 4; cGMP-independent signaling may also be involved in vasodilation.

NO is produced mainly from L-arginine by the enzyme endothelial nitric oxide synthase (eNOS), but can also be produced from non-enzymatic pathways.

Studies show that dysfunction in the production and/or bioavailability of NO is characteristic of endothelial dysfunction, which has been linked to several cardiovascular diseases, including hypertension and atherosclerosis.

Reduces blood pressure

Hypertension is a condition that millions of people worldwide deal with that can be detrimental to health and a precursor for several other chronic health conditions.

It's suggested that people with HBP have impaired ability to use nitric oxide 5; impaired NO bioactivity is also implicated in arterial stiffness, which is a major risk factor in systolic hypertension.

But how does NO reduce blood pressure?

Research suggests that a diet high in fruits and vegetables can reduce blood pressure, which may be due to the presence of certain compounds, including nitrate. Nitrate is a compound that's found in things like beetroot and dark leafy greens that, when converted to nitric oxide, dilates blood vessels to increase blood flow.

When blood can flow through arteries easier, it reduces pressure on the blood vesting lining and thus reduces blood pressure. Several studies have shown that nitrate produces beneficial effects on blood pressure because of its bioconversion to nitric oxide 6-8.

Enhances athletic performance

Apart from boosting blood flow for greater oxygen and nutrient delivery to active muscle tissue, nitric oxide has also been shown to enhance exercise performance. Because of its role in dilating blood vessels, it can help to increase the delivery of nutrients required for muscle performance.

A 2016 study looked at the effects of nitrate ingestion on bench press performance until failure in twelve active resistance-trained men 9. Participants drank either 400 mg of nitrate (from beetroot) or a blackcurrant placebo before bench pressing 60% of 1RM for 3 sets until failure with 2 minutes rest interval between sets.

Results showed a significant difference in reps to failure and total weight lifted between the two groups, suggesting that nitrate supplementation may offer performance advantages for resistance training.

Other studies have found nitrate derived from beetroot elicits positive effects on exercise performance, specifically oxygen uptake, power output, and time to exhaustion 10, 11.

Are Nitric Oxide Supplements Safe?

Dosing your fitness supplements correctly can be a challenge; it's a fine line between taking enough to get the pump but not too much to tank your workout.

Nitric oxide isn't something that's found as a pure supplement and is instead synthesized through L-arginine, L-citrulline, or beetroot supplementation, all of which exhibit a good safety profile 12-14.

However, consuming large amounts of nitrate-rich beetroot or beetroot juice may result in stool discoloration, although it's nothing to be concerned about.

Can You Take Nitric Oxide Supplements Daily?

While the safety profile on NO boosters may be relatively good, you still want to be mindful of what you're taking, as many products contain additional ingredients that may not be safe to consume daily.

However, something like beetroot juice has shown positive results with just two weeks of supplementation 15. But because dietary nitrate is widely available in several fruits and vegetables, increasing your intake of certain foods—beets and dark leafy greens—can do wonders for boosting NO levels.

As for supplements, ensure you're taking ones that are research-backed with appropriate dosages to guarantee results.
