Osterly Market Beetroot Black Pepper – Nitric Oxide Workout Support

Organic beetroot with black pepper for absorption.

Beetroot extract taken for its nitrate content, with black pepper included to improve uptake.

What it's for

Dietary nitrate from beetroot converts to nitric oxide, which relaxes blood vessels and improves blood flow. This is one of the better-evidenced sports supplements: several trials show measurable improvements in endurance performance and oxygen efficiency. The effect is real, modest, and depends entirely on the nitrate content — which most labels do not state.

How to take it

• Take two to three hours before exercise if you are using it for performance — that is when blood nitrate peaks
• Daily use also works; effects build over several days of consistent intake
• Do not use antibacterial mouthwash. Oral bacteria are a required step in converting nitrate to nitrite, and mouthwash blocks it
• Beetroot turns urine and stool pink. This is harmless and startling the first time

On the label

• Organic beetroot extract
• Black pepper extract for absorption
• 120 capsules

What this is not

• Not a stimulant
• Not a pre-workout
• Not standardised to nitrate content — which is the honest limitation here

The straight answer

The mouthwash point is real and most people have never heard it. If you rinse with an antibacterial mouthwash, you are undoing most of what this does.
