Carrot juice vs green juice: sweetness, nutrients and how to choose

The taste difference: where to start

Carrot juice is naturally sweet. A 250ml glass contains roughly 8g of natural sugar from the carrots, which makes it bright, pleasant, and easy to drink. Green juice is leafy and herbaceous, with minimal or no fruit added. The natural sugar is 2–4g per 100ml depending on the blend. Sweetness isn't good or bad — it's about what you're reaching for and when.

If you're new to juicing and like sweet flavours, carrot is the easier entry point. If you prefer vegetable-forward tastes and lower sugar, green is the natural choice. Many people drink both, rotating by mood, meal, or routine.

Carrot juice: naturally sweet, orange-led

Carrots are the star of carrot juice. Sweet Carrot (with apple and lime) softens the carrot's earthiness and adds subtle tartness. Carrot Kick (with ginger and lemon) keeps the carrot front and centre but adds a warming, peppery lift. Both are fundamentally carrot-led.

Carrot juice is high in vitamin A via beta-carotene, which supports normal vision. That's the nutritional anchor. Good if you like sweetness or you're new to juicing. Works as a breakfast drink or the naturally sweet part of your day. Many people pair it with breakfast for better nutrient absorption.

Green juice: leafy, herbaceous, minimal fruit

Green juice is kale, spinach, celery, parsley — the leaves themselves. Pure Greens is zero-fruit, delivering maximum leaf per bottle. Balanced Greens softens the leaf profile with a little fruit. Core Greens adds apple and ginger for smoothness. The nutrient density is the payoff for less sweetness.

Green juice is high in vitamin K, folate, iron, and magnesium. Different nutrients entirely from carrot. The taste is leafy and herbal, with a slight bitterness that some people find clean and others need to warm up to. Many people prefer it without breakfast — lighter on the stomach, no competition from food flavours.

What each juice delivers

Carrot juice leads with beta-carotene (vitamin A), plus potassium and some folate. Green juice leads with vitamin K, folate, iron, magnesium, and vitamin C. They don't overlap much. The nutritional stories are distinct.

If your goal is vision support, carrot is the direct route. If your goal is bone health (vitamin K), cognitive function (iron and folate), or gut health (the greens' broader profile), green juice is the anchor. Many people drink both because they serve different nutritional purposes.

Sugar: carrot is moderate, green is minimal

Carrot juice contains ~8g sugar per 100ml, which is moderate (not "low sugar" despite what some marketing claims). That's the trade-off for the sweetness — the natural sugars from carrots. Green juice is 2–4g per 100ml depending on the blend, much gentler on blood sugar. If you're watching sugar intake, green is the practical choice. If you like sweetness and prefer carrot's flavour, carrot is fine — it's a whole-food sweet, not added sugar.

The energy profile is different too. Carrot's natural sugars give a gentle lift; greens are steadier, no spike. Choose by what your body needs at that moment.

When to drink each: timing that makes sense

Carrot: morning or midday (the natural energy and sweetness pair well with breakfast or a midday pick-me-up). Best with a meal that includes fat for optimal beta-carotene absorption. Green: any time; many people prefer it without breakfast (lighter on the stomach, the leaf profile stands alone). Can be morning, midday, or evening. No breakfast competition, no sugar spike. Both work frozen and thawed.

Build your routine by what fits your day. Some people rotate: carrot some mornings, green others. Others stick with one and alternate with other juices or whole foods.

Can you drink both? Yes, and why many people do

Absolutely. Different nutrients, different taste, different energy. Some people rotate: carrot some mornings, green others. Some drink both daily (carrot at breakfast, green at lunch or later). They pair well in a weekly routine because they complement, not compete.

If you're building a juice routine, you might start with whichever appeals to you, add the other after a few weeks, and see how they fit. No rule says you have to choose. Many of our subscribers do both.

Neither juice has fibre — and that's okay

Both carrot and green juice are pressed, so both lack the insoluble fibre that whole vegetables have. Eating whole carrots alongside carrot juice, and eating whole greens alongside green juice, is the complete picture. The juices are nutrient top-ups concentrated from multiple vegetables in one glass. Fibre is something to get from whole vegetables, whole grains, legumes — the juices are the liquid nutrient layer.

Cost: they're the same

Both RJ carrot and green juices are £26.95 per 6-pack (250ml) or equivalent for 500ml packs. Choose by what suits your palate and routine, not price. Subscribe and save 10% on whichever you pick, or both.

If you want something in between: Celery Twist

Looking for a middle ground? Celery Twist is celery-led with apple and a hint of lemon — lighter than pure carrot but more vegetable-forward than pure green. It's the bridge between sweetness and leaf. Some people use it to ease into green juice, or simply because they like the balance.

Carrot and green juices

The bottom line

Carrot juice is naturally sweet from carrots; green juice is leafy and herbaceous. Carrot delivers beta-carotene (vitamin A); greens deliver vitamin K, folate, iron, and magnesium. They're complementary, not competitive. Choose by taste and routine — if you like sweetness, start with carrot; if you prefer leafy, start with green. Many people drink both because they serve different purposes and taste completely different. Carrot juice fits easily into a daily routine; so does green juice. Neither requires choosing between them.
