Beet Smoothie Recipe: 5 Earthy-Sweet Blends for Energy and Performance

Beetroot is the nutritional world’s most unfairly dismissed vegetable. Its deep earthy flavour divides opinion sharply — but blended into a smoothie with the right companions, that earthiness becomes a rich, almost wine-like depth that makes for one of the most distinctive and genuinely functional smoothie bases you can use. More importantly, beets contain a nutritional compound — dietary nitrates — that converts in the body to nitric oxide, with documented effects on blood pressure, exercise performance, and cognitive blood flow that few other foods can match.

This guide gives you five beet smoothie recipes across the full spectrum from fruity and mild to protein-packed and indulgent, plus the science explaining why beet smoothies work so well, practical guidance on choosing the right beet form for your blender, and answers to the questions everyone has after their first beet smoothie (“why is my urine red?”).

The Science Behind Beet Smoothies

Dietary Nitrates and the Nitric Oxide Pathway

Beetroot contains among the highest dietary nitrate concentrations of any vegetable: approximately 250–400mg of nitrate per 100g of raw beet, compared to 5–10mg in most other vegetables. But nitrate itself isn’t the active molecule. The pathway works like this:

1. You consume dietary nitrate from beetroot
2. Salivary bacteria on your tongue reduce nitrate (NO3⁻) to nitrite (NO2⁻) — this is why chewing matters and why using antibacterial mouthwash before consuming beets eliminates much of the benefit
3. Swallowed nitrite is further reduced in the stomach and blood to nitric oxide (NO)
4. Nitric oxide signals vascular smooth muscle to relax, dilating blood vessels

The effects are measurable: researchers at the University of Exeter consistently found that 300–500ml of beetroot juice reduced systolic blood pressure by 4–10 mmHg within 2–3 hours and reduced the oxygen cost of submaximal exercise by 2–3% — equivalent to consuming the performance benefit of weeks of altitude training in a single drink. Cyclists and runners have used beet juice as a legal performance aid since these studies were published around 2009–2011.

For smoothies, these benefits translate directly: one medium beetroot (150–200g) per smoothie delivers roughly 300–400mg dietary nitrate — the same effective dose used in the Exeter studies.

Betalains — Not Anthocyanins

The deep red-purple pigment in beets is not the same as the anthocyanins in berries or red cabbage. Beet colour comes from betalains — a completely different class of nitrogen-containing pigments divided into red-purple betacyanins (mainly betanin) and yellow betaxanthins. Betalains are potent antioxidants with anti-inflammatory effects and have demonstrated the ability to inhibit certain inflammatory enzymes (including COX-1 and COX-2) in laboratory studies. They are also water-soluble and completely harmless — which explains the alarming-looking but totally benign red urine or stool that follows beet consumption in some people (see FAQ).

Betaine and Liver Health

Beets are one of the richest dietary sources of betaine (trimethylglycine), with approximately 128–200mg per 100g raw beet. Betaine is a methyl donor involved in homocysteine metabolism (elevated homocysteine is a cardiovascular risk factor) and in protecting liver cells from fatty accumulation. Studies on betaine supplementation have shown benefits for non-alcoholic fatty liver disease (NAFLD) — a condition increasingly common in adults eating Western diets. One beet smoothie per day provides a meaningful, food-form dose of betaine as part of an overall liver-friendly eating pattern.

Folate

Raw beetroot provides approximately 109 mcg of folate per 100g (27% of the daily value), making it one of the more significant vegetable sources of this essential B vitamin needed for DNA synthesis, cell division, and crucially, for neural tube development during the first trimester of pregnancy. Folate degrades quickly with heat — raw or minimally processed beet (as in smoothies) preserves this nutrient far better than cooked beet.

Choosing Your Beet Form

The form of beet you use affects both convenience and nutritional profile.

Raw Fresh Beetroot

Highest in dietary nitrates and folate. Peel (or scrub well if organic), chop into 2–3 cm pieces, and blend — most high-powered blenders handle raw beet without issue. For weaker blenders, pre-soak in water for 30 minutes to soften slightly. Raw beet has the most pronounced earthy flavour but also the highest nutritional value.

Pre-Cooked Vacuum-Packed Beets

Convenient and available in most supermarkets. Cooking reduces nitrate content by approximately 20–30% through leaching into cooking water, but these are still excellent for smoothies. The cooked flavour is milder and sweeter than raw, which many people prefer. Drain the liquid before blending — it can make the smoothie watery.

Frozen Beetroot Chunks

Often available pre-cut and frozen. Nutritional retention is excellent (freezing preserves nitrates well). Use straight from frozen — acts as an ice equivalent and chills the smoothie. Most convenient option for regular beet smoothie making.

Beet Powder

Concentrated, shelf-stable, and easy to dose (1–2 tbsp per smoothie). Quality varies significantly between brands — look for powders made from whole beets without maltodextrin filler. Beet powder has a slightly more concentrated flavour and earthy intensity than fresh. Useful for travel or when fresh beet isn’t available. Typical dose: 1 tbsp (approximately equivalent to 50–75g fresh beet in nitrate content, depending on processing).

Beetroot Juice (100% Unsweetened)

The form used in most of the clinical research. Convenient and concentrated — 100ml of quality beet juice typically equals 150–200g fresh beet in nitrate content. Use 100–150ml per smoothie. James White, Beet It, and Biotta are well-regarded brands with documented nitrate content. Avoid beetroot juice “drinks” with less than 70% beet content.

Recipe 1: Classic Beet Berry Smoothie

The most popular entry point for beet smoothies — the berry flavour completely dominates the beet earthiness, leaving only the deep red colour and an underlying richness as evidence of the beet.

Ingredients

• 100g raw or frozen beetroot, roughly chopped
• 100g frozen mixed berries (strawberries, raspberries, blueberries)
• 1 medium banana, frozen
• 200ml unsweetened almond milk (or oat milk)
• 1 tsp raw honey (optional)

Instructions

1. Add almond milk to the blender first (this prevents the beet from sticking to the blades).
2. Add beetroot pieces, frozen berries, and frozen banana.
3. Blend on high for 60–90 seconds. Raw beet takes longer to fully break down than soft fruits — don’t rush this.
4. Check consistency — if too thick, add 50ml more milk and blend 15 seconds.
5. Taste before adding honey. The frozen banana and berries usually provide enough sweetness.
6. Pour into a tall glass. The colour will be a vivid magenta-purple.

Nutritional Snapshot (approximate)

• Calories: ~215 kcal
• Dietary nitrate: ~280–350mg
• Fibre: 6g
• Vitamin C: ~35mg
• Folate: ~85 mcg

Why it works: Frozen banana provides the creamy base that balances beet’s earthiness perfectly. The mixed berry acids (citric, malic) contrast with the beet’s earthy-sweet character. This is the recipe that converts beet-sceptics.

Recipe 2: Beet Apple Ginger Energiser

A refreshing, slightly spiced combination that leans into the beet’s natural sweetness with apple and brightens the whole drink with ginger. This recipe is particularly well-designed for mornings — the ginger is mildly stimulating, the apple delivers steady glucose, and the beet nitrates prime cardiovascular function for the day ahead.

Ingredients

• 100g frozen beetroot chunks (or 100ml beet juice)
• 1 medium apple, cored and roughly chopped (no need to peel)
• 2 cm fresh ginger root, peeled
• Juice of 1 lemon
• 150ml cold water (or coconut water for added electrolytes)
• 4–5 ice cubes
• Small pinch of black pepper (enhances bioavailability of some compounds)

Instructions

1. Add water and lemon juice to blender.
2. Add beet, apple, ginger, and ice.
3. Blend 60–75 seconds on high until completely smooth. Ginger takes a moment to fully incorporate.
4. Add black pepper, blend 10 more seconds.
5. Taste — if too tart, add ½ tsp honey. If too earthy, add more lemon juice.
6. Serve immediately — this one oxidises quickly and is best consumed fresh.

Nutritional Snapshot (approximate)

• Calories: ~120 kcal
• Dietary nitrate: ~300–380mg
• Fibre: 5g
• Vitamin C: ~30mg
• Gingerols/Shogaols: anti-nausea and anti-inflammatory phenolic compounds

Why it works: This is the lowest-calorie recipe in the set and the one with the cleanest “juice-like” character — appropriate for those who want the beet’s performance benefits without a creamy, heavy smoothie. The apple’s malic acid and the lemon’s citric acid cut through the earthiness effectively. Ideal before morning exercise.

Recipe 3: Beet Chocolate Protein Smoothie

Chocolate and beet is one of the great underappreciated flavour combinations in the food world — deployed to stunning effect in classic “chocolate beet cake” recipes from Scandinavia and Eastern Europe. In smoothie form, the combination becomes a thick, indulgent, genuinely delicious post-workout shake with serious nutritional credentials.

Ingredients

• 100g frozen beetroot
• 1 scoop (30g) chocolate protein powder (whey or pea)
• 2 tbsp raw cacao powder
• 1 tbsp almond butter
• 1 medium banana, frozen
• 200ml unsweetened oat milk
• ½ tsp vanilla extract

Instructions

1. Add oat milk to blender first.
2. Add protein powder and cacao — blend 20 seconds to dissolve powder before adding other ingredients (prevents lumping).
3. Add beetroot, banana, almond butter, and vanilla.
4. Blend 60–75 seconds on high.
5. Check sweetness — the protein powder and banana usually provide enough. Add a small amount of maple syrup if needed.
6. The texture should be thick and milkshake-like. Serve in a wide glass or eat with a spoon.

Nutritional Snapshot (approximate)

• Calories: ~395 kcal
• Protein: ~28g
• Dietary nitrate: ~260–320mg
• Fibre: 8g
• Theobromine (from cacao): mild stimulant, vasodilatory — synergistic with beet nitrates

Why it works: Cacao contains theobromine, a mild vasodilator and stimulant related to caffeine but with a smoother, longer-duration effect. Combined with beet’s nitric oxide production, this recipe stacks two distinct vasodilatory mechanisms — making it an unusually science-aligned post-workout shake. The almond butter slows digestion and adds healthy fats that support fat-soluble nutrient absorption. With 28g protein, this is a complete post-workout meal replacement.

Recipe 4: Beet Citrus Sunrise

A bright, refreshing combination that pairs beet’s earthy sweetness with the sharp citrus notes of orange and blood orange. The colour is extraordinary — a gradient from deep magenta to vivid orange if you pour carefully. This recipe is highest in vitamin C of the five and was designed specifically around immune support and iron absorption.

Ingredients

• 80g frozen beetroot
• 2 medium oranges, peeled and segmented (or 200ml fresh orange juice)
• 1 carrot, roughly chopped
• 1 cm fresh turmeric (or ½ tsp turmeric powder)
• Pinch of black pepper
• Juice of ½ lime
• 4–5 ice cubes

Instructions

1. Add orange juice/segments to the blender first.
2. Add beetroot, carrot, turmeric, and lime juice.
3. Blend 60 seconds. Carrot takes a little time to fully break down.
4. Add ice and blend 20 more seconds.
5. Add black pepper, blend briefly.
6. Taste and adjust — add honey if you prefer sweeter; add more lime for extra brightness.

Nutritional Snapshot (approximate)

• Calories: ~175 kcal
• Dietary nitrate: ~350–420mg (beet + carrot)
• Vitamin C: ~120mg (100%+ DV)
• Beta-carotene: ~6mg (from carrot)
• Curcumin: meaningful amount with enhanced absorption (black pepper)

Why it works: Carrots add additional nitrate (around 100–150mg per 100g) and beta-carotene, stacking nicely with beet’s nitrate for a combined nitric oxide effect. The vitamin C from orange is excellent for iron absorption (both beet and carrot provide non-haem iron), and the turmeric-black pepper combination adds anti-inflammatory curcumin in a practically bioavailable form. This is the immune-support and vascular health recipe of the set.

Recipe 5: Beet Kefir Probiotic Smoothie

The gut-health-focused option in this series combines beet’s prebiotic fibres (inulin and pectin from the beet cell wall) with the live cultures in kefir, creating a synbiotic combination. Beet’s betalain pigments and polyphenols also act as selective prebiotics, preferentially feeding Bifidobacterium species — the same bacteria abundant in kefir. This is the most gut-microbiome-aligned recipe in the set.

Ingredients

• 100g frozen or cooked beetroot
• 150ml plain full-fat kefir
• 100g frozen strawberries
• 1 tsp raw honey
• ½ tsp vanilla extract
• Pinch of cinnamon

Instructions

1. Add kefir to the blender first.
2. Add beetroot and frozen strawberries.
3. Blend 45–60 seconds on high until completely smooth.
4. Add honey, vanilla, and cinnamon. Blend 10 seconds to combine.
5. Taste — adjust honey for sweetness or add a squeeze of lemon for brightness.
6. Serve immediately. The kefir creates a thick, almost yogurt-smoothie consistency.

Nutritional Snapshot (approximate)

• Calories: ~225 kcal
• Protein: 8g
• Dietary nitrate: ~270–340mg
• Probiotics: 10–20+ billion CFU (from kefir)
• Calcium: ~280mg

Why it works: Cinnamon improves insulin sensitivity and adds a warming complexity that softens beet’s earthiness. Strawberries provide brightness and vitamin C. The kefir creates a thick, satisfying texture that makes this recipe the most filling of the five. If you have one beet smoothie to serve to a beet-sceptic, this — with its familiar strawberry-yogurt base — is the best introduction.

Beet Smoothie Tips and Troubleshooting

Handling the Earthiness

Beet’s earthy character comes from geosmin, the same volatile compound responsible for the smell of rain on dry earth (petrichor). Geosmin is extremely potent — the human nose detects it at concentrations as low as 0.5 nanograms per litre. In smoothies, the most effective counterbalances are: acid (lemon, orange, lime juice), sweetness (banana, honey), fat (almond butter, kefir, coconut milk), and dark chocolate or cacao. Starting with cooked rather than raw beet also substantially reduces geosmin intensity.

Staining Prevention

Beet stains are a genuine nuisance. Betalains bind to proteins in cutting boards, clothing, and counter surfaces quickly. Work on a dark-coloured cutting board or a piece of baking parchment, wear an apron, and wash your hands, blender, and surfaces immediately after contact. Lemon juice neutralises beet stains on hands effectively; cold water rinse before hot water on fabric (hot water sets the stain permanently).

Raw vs Cooked Beet in Smoothies

Raw beet: higher in nitrates and folate, more pronounced earthy flavour, requires a powerful blender for smooth results. Cooked beet: milder and sweeter, easier to blend, slightly lower nitrates (20–30% loss through leaching), but more convenient and suitable for weaker blenders. For performance/BP purposes, raw maximises nitrate dose. For flavour and ease, cooked is the better choice for beginners.

Blender Power Considerations

Raw beet is dense and fibrous. A basic blender (under 600W) may leave fibrous beet strands in the smoothie. Solutions: pre-cook the beet, use beet powder or beet juice instead of whole beet, or pre-soak raw beet chunks in water for 30 minutes to soften them slightly before blending. Powerful blenders (NutriBullet Pro 900W+, Vitamix, Blendtec) handle raw beet without issue.

Nutritional Overview

Across all five recipes, beet smoothies deliver a consistent nutritional profile:

• Dietary nitrate: 260–420mg per smoothie — within the effective clinical dose range
• Folate: 80–110 mcg per smoothie from the beet component (20–27% DV)
• Betaine: 90–180mg per smoothie — meaningful for homocysteine metabolism
• Potassium: 400–700mg per smoothie — important for blood pressure management
• Manganese: 0.4–0.6mg per smoothie from beet (significant for antioxidant enzyme superoxide dismutase)
• Fibre: 4–8g per smoothie when using whole beet rather than juice

When to Drink a Beet Smoothie for Best Performance Effects

Timing matters for the nitrate-nitric oxide effect. Peak nitric oxide production from dietary nitrate occurs approximately 2–3 hours after consumption. If you’re exercising or have a stressful physical day ahead:

• Morning exercise (7am): Drink beet smoothie the night before (10–11pm) for overnight preparation, or very early morning (4–5am) for a 7am workout
• Afternoon exercise (1–3pm): Drink beet smoothie at breakfast (8–10am) — ideal timing
• Evening exercise (5–7pm): Drink beet smoothie with lunch (2–3pm)

For blood pressure benefits, daily morning consumption is well-supported by the research — the vasodilatory effect of nitric oxide lasts 12–24 hours with regular intake, and daily beet consumption appears to have a cumulative benefit on vascular tone beyond the acute effect.

Frequently Asked Questions

Why is my urine pink after a beet smoothie?

This is called beeturia and happens in approximately 10–15% of the population. It’s caused by betanin (the red betalain pigment) passing unmetabolised through the digestive tract and being excreted in urine. It is completely harmless and not a sign of blood in urine. Beeturia is more common in people with lower stomach acid (who don’t break down betalains as efficiently) and in people with iron-deficiency anaemia (the iron status affects betanin metabolism). If you don’t have beeturia, it means your gut bacteria are breaking down the betalains before they reach circulation — both outcomes are normal.

Can I add beet to a green smoothie?

Yes — beet works particularly well with spinach because the red-green colour combination produces an appealing deep purple rather than a muddy brown. Use 50–80g beet with a larger quantity of spinach, add lemon juice to brighten, and include banana or apple for sweetness. The beet’s earthy notes and the spinach’s vegetal notes actually complement each other better than you might expect.

Is a beet smoothie safe every day?

Yes, in the quantities used in these recipes (100–150g fresh beet equivalent per day). Daily beet consumption is standard practice in competitive sport nutrition. Potential concerns at very high doses (300g+ per day consistently): oxalate load — beets are moderately high in oxalates, which can contribute to kidney stone formation in susceptible individuals. If you have a history of calcium oxalate kidney stones, discuss high daily beet consumption with your doctor. Otherwise, 100–150g per day is well within safe and beneficial ranges.

Does cooking beet reduce its health benefits?

Yes, particularly for nitrate content (20–30% reduction through leaching into cooking water) and folate (heat-sensitive, 30–50% reduction). However, cooking also increases the bioavailability of some other compounds by breaking down cell walls. The practical answer: raw beet is better for nitrate and folate; cooked beet is fine for betalains, betaine, and minerals. For smoothies where performance and blood pressure effects are the goal, raw or frozen raw beet is the better choice.

Can beet smoothies lower blood pressure?

Yes, with meaningful and well-documented evidence. Multiple meta-analyses have confirmed that 300–500ml of beetroot juice or equivalent raw beet reduces systolic blood pressure by 4–10 mmHg in both normotensive and hypertensive individuals, with effects lasting 12–24 hours after a single dose and potential cumulative benefits with daily consumption. This positions beet smoothies as one of the most evidence-based dietary tools for blood pressure management, though they don’t replace medical treatment for established hypertension.

Conclusion

Beet smoothies are one of the few foods where the nutritional marketing actually understates the reality. The dietary nitrate-nitric oxide performance pathway is not wellness-industry hype — it’s mainstream sports nutrition with published clinical trials behind it. The betalain antioxidants, betaine liver support, and folate content add layers of benefit that make the beet smoothie genuinely multifunctional in a way that most smoothie ingredients simply aren’t.

The five recipes above are calibrated to make beet accessible regardless of your current relationship with its flavour: start with the chocolate protein if you want the benefits hidden in something that tastes like dessert, move to the classic berry once you’re confident in the flavour, and work toward the apple-ginger or citrus versions as your palate develops an appreciation for the earthiness itself. The kefir probiotic version sits at the intersection of gut health and cardiovascular performance — arguably the most holistic single glass in this entire recipe set.
