Natural Nitrates
A compound that can improve blood flow, exercise performance, and cardiovascular health.
Also known as: Dietary Nitrates
Overview
Natural nitrates are compounds found in certain vegetables, particularly leafy greens and beetroot. In the body, nitrates are converted to nitric oxide, a molecule that relaxes blood vessels, improves blood flow, and has various other health benefits.
Key Benefits
Enhances Exercise Performance
By improving blood flow and oxygen delivery to muscles, nitrates can enhance endurance and reduce the oxygen cost of exercise.
Supports Cardiovascular Health
Nitric oxide helps to relax and widen blood vessels, which can lower blood pressure and improve overall cardiovascular function.
Improves Blood Flow
The vasodilating effects of nitric oxide can improve blood flow to various parts of the body, including the brain.
Dosage & How to Take
A common dose of natural nitrates for performance enhancement is 300-600 mg, taken 1-2 hours before exercise. This can be obtained from beetroot juice or a concentrated supplement.
| Purpose | Dose | Notes |
|---|---|---|
| Exercise Performance | 300-600mg | Taken 1-2 hours before activity. |
| Blood Pressure Support | 200-500mg per day | Can be obtained from a diet rich in nitrate-containing vegetables. |
Best Time to Take
For exercise performance, take 1-2 hours before activity. For general health, consume throughout the day.
With or Without Food
Can be taken with or without food.
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| Beetroot Juice | High | A natural and effective way to consume nitrates. | Can be high in sugar. |
| Beetroot Powder | High | A concentrated and low-sugar alternative to juice. | Can be mixed with water or other beverages. |
| Leafy Green Vegetables | Medium | A whole-food source of nitrates. | The nitrate content can vary. |
Side Effects & Safety
Common
- Beeturia (red or pink urine and stools) from beetroot consumption
- Upset stomach in some individuals
Rare
- Hypotension (low blood pressure) at very high doses
Contraindications
- Individuals taking medication for low blood pressure should consult with their doctor before supplementing with nitrates.
Interactions
Nitrates can enhance the effects of blood pressure-lowering medications, potentially causing blood pressure to drop too low.
Combining nitrates with erectile dysfunction drugs like sildenafil (Viagra) can cause a dangerous drop in blood pressure.
Scientific Research
A review on nitrates' health benefits and disease prevention
Nitrates enhance cardiovascular health by lowering blood pressure. Nitric Oxide (NO) relaxes and widens arteries and veins, resulting in improved blood flow.
Dietary Nitrate: The New Magic Bullet?
Dietary nitrate supplementation reduces the oxygen cost of low-intensity exercise and enhances tolerance to high-intensity exercise in humans.
