Red Bell Pepper
Juice

One pound of red bell peppers (approximately 454g) yields roughly 280–320ml in a cold press or masticating juicer — about 9.5–11 oz, close to a full glass. Centrifugal juicers extract noticeably less: typically 220–260ml from the same pound due to their less effective handling of soft, fleshy produce.

A medium red bell pepper weighs about 150–185g, so one pound is roughly 2–3 medium peppers. The thick, fleshy walls juice efficiently; remove the seeds and core before juicing.

In a cold press or masticating juicer, 2–3 medium red bell peppers (about 350–450g) will yield close to an 8 oz cup. Centrifugal juicers are less efficient — plan on 3–4 medium peppers for the same volume.

Red bell peppers vary considerably in size. Small ones can run around 100g; large greenhouse peppers can hit 250g or more. Weighing your produce gives you a more reliable estimate than counting. Aim for 400–450g in a cold press juicer for a reliable 8 oz glass.

For a precise calculation with your actual weight and juicer, use the calculator.

A 5 lb bag (2,268g) yields approximately 1,400–1,590ml in a cold press juicer — roughly 47–54 oz, or about six 8 oz glasses. The same bag in a centrifugal juicer produces closer to 1,100–1,300ml.

At 8 oz per day, a 5 lb bag covers about 5–6 days in a cold press juicer. Red bell pepper juice has a mild, sweet flavor that blends well with carrot, apple, ginger, or citrus — a 5 lb bag is enough to anchor a week of blended juice without dominating the mix.

Freshness is the biggest variable. Red bell peppers that have started to soften, wrinkle, or lose their firmness have lost moisture and will yield less than crisp, fully ripe peppers. Beyond freshness, size matters — larger peppers have proportionally more flesh and less core per gram.

Prep affects yield too: removing the seeds and white membrane before juicing is standard. The membrane is low in moisture; the seeds are firm enough to stress some augers. Basic prep — quarter the pepper, remove the stem and seed core, feed the flesh panels in — consistently outperforms dropping in whole peppers.

Juicer type has a larger effect on bell peppers than on harder produce like carrots or beets. Centrifugal juicers struggle with soft, fleshy vegetables and leave significantly wetter pulp.

Yes — removing the seeds and core before juicing is the standard approach. The seeds are relatively firm and can stress auger-based juicers over time. In centrifugal juicers they tend to pass through without issue, but they contribute a slightly bitter, astringent note that's noticeable in red pepper juice where the sweetness should come through cleanly.

The white pith and ribs are fine to include — they contain some vitamin C and nutrients — but removing as much pith as possible produces a cleaner, sweeter result. Red bell pepper juice is naturally mild and sweet; minimizing the membrane preserves that character.

Basic prep: quarter the pepper, cut out the stem and seed core, and feed the flesh quarters directly into the juicer.

Yes, in two meaningful ways. First, yield efficiency: a cold press or masticating juicer extracts 10–20% more juice per pepper than a centrifugal juicer, which means more total nutrients per batch from the same produce.

Second, vitamin C retention: centrifugal juicers introduce oxygen through high-speed spinning, which degrades vitamin C during extraction. Red bell pepper delivers approximately 175mg of vitamin C per 100ml of cold press juice — an exceptional amount. Centrifugal extraction can reduce that by 10–30%, which matters when vitamin C is one of the main reasons you're juicing these peppers.

The nutrition values on this page are calculated for cold press juice. A centrifugal cup of the same size will contain somewhat less vitamin C.

Moderate — about 6.5g of natural sugar per 100ml of juice, which is higher than green bell pepper juice (3.7g) but still far below most fruit juices. The sweetness comes from the full ripening process: red bell peppers are the same fruit as green bell peppers, just left on the vine until fully ripe, which converts starches into natural sugars.

The glycemic impact is low. Red bell pepper juice has a pleasant mild sweetness that most people find much more drinkable than green or yellow bell pepper juice, without the sugar load of carrot or beet juice. It's a practical choice for people who want nutrient-dense juice without spiking blood sugar.

Red bell pepper juice has a mild, slightly sweet, lightly vegetal flavor — significantly less bitter than green bell pepper juice, with a clean finish. Drunk straight it's pleasant but thin; most people blend it where its nutritional density does the heavy lifting without competing with other flavors.

Classic pairings: carrot for earthy sweetness and visual depth; apple or pear to amplify the sweetness; tomato for a savory direction; ginger and citrus for brightness and complexity; cucumber and celery for a clean, low-sugar base. The red pepper-carrot-orange-ginger combination is particularly well-established — the flavors reinforce each other.

Because it lacks the bitterness of green pepper juice, red bell pepper works well in recipes aimed at someone new to vegetable juicing who wants something approachable.

Exceptionally so. Red bell pepper juice provides approximately 175mg of vitamin C per 100ml in a cold press juicer — roughly 195% of the daily recommended intake in a single 100ml serving. An 8 oz glass delivers close to 415mg, more than four times the daily value.

For context, that's substantially more vitamin C than orange juice (about 50mg per 100ml) and more than green bell pepper juice per equivalent serving, despite green being commonly cited as the "vitamin C pepper." The difference is that red peppers are fully ripe, which pushes vitamin C content higher than the unripe green stage.

Because vitamin C is heat-sensitive and oxidizes quickly, cold press and masticating juicers preserve significantly more than centrifugal juicers. Drink within 24–48 hours for maximum retention.

Cold press red bell pepper juice keeps well for 48–72 hours in a sealed glass container filled to the top to minimize air space. The flavor holds reasonably well — it may become slightly more bitter and vegetal as enzymes continue working, but it doesn't degrade as quickly as leafy green juices.

Centrifugal juice has more oxidation during extraction and is best consumed within 24 hours. Red bell pepper juice tends to separate in the fridge — shake or stir before drinking.

Vitamin C is the most oxidation-sensitive nutrient in this juice. For maximum vitamin C retention, drink within the first 24 hours regardless of juicer type.

The nutritional case for red bell pepper juice is led by three things: vitamin C at about 175mg per 100ml, beta-carotene at approximately 2.5mg per 100ml (which converts to vitamin A), and a broad antioxidant profile including lutein and zeaxanthin.

The vitamin C supports immune function, collagen synthesis, and iron absorption. The carotenoids — particularly lutein and zeaxanthin — have well-documented associations with eye health, potentially reducing risk of macular degeneration and cataracts. Beta-carotene converts to vitamin A, which supports skin, vision, and immune function.

Red bell peppers contain no capsaicin (the compound that makes hot peppers spicy), making them well-tolerated by people sensitive to heat. There are no known safety limits for red bell pepper juice at typical serving sizes — unlike, say, carrot juice where high beta-carotene intake can cause carotenemia. At 8 oz per day, red bell pepper juice is one of the lower-risk, higher-reward juicing choices.
