Q1. What is Beet-420 and what does it do?
It's a caffeine-free, pre-endurance beetroot supplement standardized to 420 mg of dietary nitrates per serving. Those nitrates support the body's production of nitric oxide, which improves blood flow and can lower the oxygen cost of exercise — helping endurance. It's a performance supplement taken around training, not a medicine and not a stimulant.
Q2. How do beetroot nitrates actually improve endurance?
Through a chain: dietary nitrate is reduced to nitrite (with help from bacteria in your mouth), then converted to nitric oxide in the body. Nitric oxide relaxes and widens blood vessels, improving blood flow and reducing how much oxygen your muscles need at a given intensity — so a set pace can feel a bit easier and more sustainable.
Q3. When and how should I take it?
Mix one 6.5 g serving into 250 ml of water (cold or hot), stir until dissolved, and drink it 30–45 minutes before your endurance session. For a key event, some athletes also take it daily for a few days beforehand to build the effect.
Q4. Why does the label say to take it before brushing my teeth?
Because the first step of the nitrate-to-nitric-oxide pathway depends on friendly bacteria on your tongue. Brushing — and especially antibacterial mouthwash — kills those bacteria and can blunt the whole effect. Taking it in the morning before you brush, and avoiding antibacterial mouthwash around your dose, protects the benefit. It's a small habit that makes a real difference.
Q5. Will it turn my urine pink?
It might, and that's completely normal and harmless — it's called beeturia, and it's just the beetroot pigment, not blood. It passes on its own.
Q6. Is it really caffeine-free? Can I still have coffee?
Yes, it's entirely caffeine-free. That's deliberate — it means it won't affect your sleep, and you can pair it with a coffee or a caffeinated gel if you want both a nitric-oxide effect and a caffeine lift. They work through different systems, so there's no doubling-up on stimulants.
Q7. Does it work for everyone?
Not equally. Nitrate supplementation tends to help recreational and sub-elite athletes more than highly-trained elites, whose bodies are already very efficient, and individual response varies. The honest advice is to try it in training and see how you respond before relying on it for a race.
Q8. Is 420 mg a meaningful dose?
Yes — it's about 6.8 mmol of nitrate, which sits within the range used in the research on beetroot and endurance. A lot of beet powders and juices are under-dosed or don't state their nitrate content, so a standardized 420 mg is a genuine advantage.
Q9. Is it vegan and clean?
Yes — it's a single standardized beetroot extract, fully vegan, and free from soy, dairy, sugar, nuts, gluten, artificial colours, fillers, emulsifiers and preservatives. Unflavoured, so it goes into water simply.
Q10. Should I take it every day?
It's best used around your endurance training and races rather than as a daily supplement for its own sake. A dose before a session helps acutely, and taking it daily for a few days into a key event can build the effect — but there's no need to take it on days you're not training toward endurance.
