Dietary Nitrates
Boosts nitric oxide for enhanced blood flow and performance.
Also known as: Inorganic Nitrate • NO3-
Overview
Dietary nitrates are naturally occurring compounds found in vegetables like beetroot and leafy greens. In the body, they convert to nitric oxide, a vasodilator that relaxes blood vessels, improves blood flow, and can enhance exercise performance and cardiovascular health.
Key Benefits
Enhanced Exercise Performance
Improves endurance and power output by reducing the oxygen cost of exercise.
Lower Blood Pressure
Relaxes blood vessels, leading to a reduction in both systolic and diastolic blood pressure.
Improved Cardiovascular Health
Enhances blood flow and oxygen delivery to tissues, supporting overall heart health.
Dosage & How to Take
The optimal dose of dietary nitrates varies depending on the desired effect, but most research uses doses in the range of 300-600 mg per day.
| Purpose | Dose | Notes |
|---|---|---|
| Athletic Performance | 300-600 mg | Taken 2-3 hours before competition. |
| Blood Pressure Reduction | 250-500 mg | Taken daily, may take several weeks for full effect. |
Best Time to Take
For performance benefits, take 2-3 hours before exercise. For general health, timing is less critical.
With or Without Food
Can be taken with or without food.
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| Beetroot Juice/Extract | High | Athletic performance and general health | A common and effective source of dietary nitrates. |
| Potassium Nitrate | High | Precise dosing in clinical research | A salt form of nitrate, less common in supplements. |
