Key takeaways
- Good blood flow supports every tissue in the body.
- Nitric oxide helps blood vessels relax.
- L-arginine is the building block of nitric oxide.
- L-citrulline helps maintain arginine levels.
- Beets, greens and watermelon support nitric oxide naturally.
Blood flow is one of the quiet foundations of men's health. It carries oxygen and nutrients to muscles, organs and glands, including the prostate and bladder, and removes waste products. As men age, circulation naturally becomes less efficient, which is one reason nutrition and lifestyle become more important.
What is nitric oxide?
Nitric oxide (NO) is a signalling molecule produced by the cells lining your blood vessels. It tells the smooth muscle in vessel walls to relax, which widens the vessels and supports healthy blood flow. Nitric oxide production tends to decline with age, inactivity and poor diet.
Key nutrients for circulation
L-Arginine
L-arginine is an amino acid the body uses directly to make nitric oxide. It's found in protein foods like poultry, fish, nuts and seeds.
L-Citrulline
L-citrulline is converted by the kidneys into arginine, which helps maintain arginine levels over time. It's naturally abundant in watermelon.
Niacin (vitamin B3)
Niacin supports energy metabolism and healthy circulation.
Beta-alanine
Beta-alanine supports muscle endurance, helping you stay active, which in turn supports healthy circulation.
Foods that support healthy circulation
| Food | Why it helps |
|---|---|
| Beets, spinach, arugula | Natural nitrates the body can turn into nitric oxide |
| Watermelon | Rich in L-citrulline |
| Nuts, seeds, poultry, fish | Sources of L-arginine |
| Tomatoes | Contain lycopene, often linked with prostate health |
| Berries, citrus, dark chocolate | Antioxidants that support blood vessel health |
Where supplements fit in
ProstaFlow combines L-arginine, L-arginine AKG, L-citrulline, beta-alanine and niacin in one daily capsule, making it easy to support circulation and men's wellness alongside a healthy diet and regular exercise.

Common questions
What does nitric oxide do?
Nitric oxide helps blood vessels relax and widen, supporting healthy blood flow throughout the body.
What is the difference between L-arginine and L-citrulline?
L-arginine is used directly to make nitric oxide, while L-citrulline is converted into arginine, helping maintain levels over time.
Which foods boost nitric oxide?
Beets, leafy greens, watermelon, nuts and seeds support nitric oxide production naturally.
