May offer mild blood flow benefits, but often overhyped for muscle growth.
Citrulline, every time. It bypasses the gut breakdown issue and raises blood arginine levels more effectively than taking arginine itself. It's what arginine wants to be.
Not directly. It's supposed to improve blood flow to muscles, but the effect is weak. Creatine is what you want for actual strength and size.
Maybe, if it's very mild. Some studies show a small benefit at high doses (5g+), but don't expect it to work like a prescription medication.

Some ingredients build up over weeks. Others act fast.
The compound effect of consistent dosing.
Check the cautions section if you have a pre-existing condition.
Some ingredients you feel. Others just work in the background.
No. Talk to your doctor. Combining them can cause a dangerous drop in blood pressure.
AAKG is Arginine Alpha-Ketoglutarate. It's just a different form. It has the same problem: still gets broken down by your gut. No proven advantage.
No. It's not a stimulant like caffeine. It's meant to improve blood flow, not provide a direct energy boost.
Most research uses 6.0g daily. Below 3.0g, you're probably wasting money. Above 9.0g, no extra benefit. The curve plateaus. Safe upper limit ~ 15.0g.
Precursor to nitric oxide (NO), a vasodilator that relaxes blood vessels and improves blood flow. Also involved in protein synthesis and immune function.
While arginine plays a role in nitric oxide production, its effectiveness as a supplement is debated due to bioavailability issues. Some studies show benefits for specific populations (e.g., those with cardiovascular issues), but results are inconsistent for healthy individuals.
Protein-rich foods like red meat, poultry, fish, and dairy products. Your body can also make it from other amino acids.
Arginine interacts with other supplements and meds. The analyzer flags interactions, dose mismatches, and timing collisions across your whole list.
