The Science-Backed Health Benefits of Beetroot: Blood Pressure, Energy & More
Have you ever felt like your energy just isn’t what it used to be — even though you’re doing your best to stay healthy?
Whether you’re walking daily, eating your veggies, or even getting decent sleep… it’s frustrating to feel sluggish or notice rising blood pressure. But one natural food could make a real difference — and it’s not exotic, expensive, or hard to find.
It’s beetroot.
This vibrant root vegetable has gained serious attention in nutrition research over the past decade — not just for its colour, but for its powerful effects on blood flow, energy, inflammation, and more. In this post (and video below), we’ll break down what the latest science says about beetroot benefits, how it works in the body, and whether beet juice or powder could be right for you.

🧬 Why Beetroot is a True Functional Food
Beetroot contains naturally occurring dietary nitrates, which your body converts into nitric oxide — a molecule that helps your blood vessels relax and widen. This improves blood flow, oxygen delivery, and nutrient transport to your muscles, heart, and brain.
Multiple studies have shown that beetroot may support:
✅ Lower resting blood pressure
✅ Improved energy and endurance
✅ Better brain blood flow and cognitive function
✅ Reduced inflammation and oxidative stress
💪 Beetroot and Exercise: What the Science Says
One of the most widely cited studies found that participants who drank 500ml of beetroot juice daily for six days experienced:
A 16% improvement in time to exhaustion
Lower oxygen use during high-intensity exercise

Even better? Another study showed that plasma nitrate — the compound that turns into nitric oxide — peaks about 2.5 to 3 hours after drinking beet juice.
That means there’s a “sweet spot” for timing your beetroot intake if you’re using it for workouts or stamina.

Beetroot’s benefits aren’t limited to exercise performance.
A 2011 study found that a high-nitrate beetroot-rich diet improved blood flow to the frontal lobes of the brain — which are responsible for memory, focus, and decision-making.
Beetroot is also rich in betalains, phenolic compounds, and vitamin C — all of which have strong antioxidant and anti-inflammatory effects. These plant compounds may help reduce the risk of:
High blood pressure
Atherosclerosis
Type 2 diabetes
Cognitive decline
Chronic inflammation
🔎 In fact, beetroot’s anti-inflammatory effects are thought to work by interrupting key immune signalling pathways — including NF-kB, which plays a central role in many inflammatory and autoimmune conditions.

According to USDA data and multiple nutrition studies, 100g of beetroot contains:
🧬 3.9g of betalains
🌿 25mg of natural dietary nitrate
🍠 Small but meaningful amounts of vitamin C, fibre, amino acids, phytosterols, and phenolic acids
This unique blend of nutrients supports its reputation as one of the most effective “food as medicine” ingredients available.
💡 How to Use Beetroot (Without Chugging Juice Daily)
You don’t have to drink litres of beet juice to get the benefits. Here are a few simple ways to include beetroot:
Grated raw beet in salads or slaws
Roasted beetroot as a side dish
Powdered beetroot in smoothies or yoghurt
Standardised beetroot extracts in capsule form — great if you want the benefits without the taste or prep
Some people also choose blends that include tart cherry, turmeric, or black pepper to support joint health and recovery — like the one I mention in the video.
🩸 Just a heads-up: if your urine turns pink after eating beets, that’s called beeturia — totally harmless!
⚠️ A Few Precautions
Beetroot is generally very safe, but a few people should proceed with care:
If you’ve had calcium oxalate kidney stones, moderate your intake and stay well hydrated — beetroot is high in oxalates.
If you’re taking blood pressure medications or nitrate-based heart medications (like nitroglycerin), speak to your doctor before adding beet supplements.
And again — beeturia may surprise you, but it’s nothing to worry about!
Beetroot is far more than just a colourful side dish. It’s a powerful, natural ally for supporting:
Healthy blood pressure
Energy and stamina
Brain blood flow
Inflammation control
And long-term cardiovascular resilience
Whether you roast it, blend it, or take it in capsule form — adding beetroot to your routine could be one of the simplest ways to support your heart, brain, and energy as you age.
