Swiss Chard
Juice

One pound of swiss chard (approximately 454g) yields roughly 230–270ml in a masticating juicer — about 7.5–9 oz. A twin gear juicer extracts a bit more: 270–320ml from the same pound. Centrifugal juicers are significantly less efficient with leafy greens: expect 135–205ml, or about 4.5–7 oz.

Swiss chard has moderate-to-low yield compared to high-water produce like cucumber or celery. The stems juice more readily than the leaves — leaving stems intact (or even juicing them separately first) improves overall extraction.

A standard bunch of swiss chard weighs roughly 450–600g. In a masticating juicer, one bunch yields approximately 225–360ml — meaning one to one-and-a-half bunches will fill an 8 oz cup, depending on bunch size and juicer efficiency.

In terms of individual leaves, large leaves weigh 40–80g each. You'd typically need 6–12 large leaves for an 8 oz serving in a masticating juicer — more if your juicer is centrifugal, where yield can be 40–50% lower for leafy greens.

Because of the bitter flavor, most people don't juice swiss chard solo — they blend it with apple, carrot, or cucumber. For a combination yield, the calculator handles mixed-produce batches.

A standard supermarket bunch (450–600g) yields approximately 225–390ml in a masticating juicer — roughly 7.5–13 oz depending on bunch size and juicer type. A twin gear juicer extracts closer to the upper end: 270–420ml. Centrifugal juicers may yield as little as 135–270ml from the same bunch.

If you're shopping for a week of daily green juice at 8 oz per day, plan on 5–7 bunches for a masticating juicer, or 7–10 bunches if you're using a centrifugal machine.

More than most produce, swiss chard yield is sensitive to freshness and technique. Wilted chard loses moisture quickly — fresh-from-the-market chard yields noticeably more than chard that's been sitting in the fridge for several days.

Technique matters too. Rolling leaves tightly before feeding them into the juicer significantly improves contact with the auger or blades, especially in masticating machines. Alternating chard leaves with a harder produce like apple or cucumber (a "push-pull" technique) also helps — the firmer produce pushes the leaves through more completely.

Stem-to-leaf ratio is another variable. The stems have higher water content and juice more easily than the leaves. Bunches with thicker, more abundant stems will yield more juice per pound.

Yes — and the gap is larger for leafy greens than for most other produce. Centrifugal juicers not only extract less juice per pound, they also introduce significant oxidation during extraction. Slow juicers extract 27% more chlorophyll and 32% higher vitamin C levels compared to centrifugal machines in head-to-head leafy green studies.

For swiss chard specifically, vitamin C and folate are the most oxidation-sensitive. The vitamin K content — which is extraordinary in swiss chard — is fat-soluble and less affected by juicer speed, but it still concentrates better in a higher-yield slow juicer simply because there's more juice per 100g of produce.

The nutrition values on this page are based on slow juicer yield at 55% extraction. A centrifugal cup will contain meaningfully less of these nutrients for the same serving size.

Extremely high — and it's worth knowing before you start. Raw swiss chard contains 830 mcg of vitamin K per 100g, and juice concentrates this further. A 100ml serving of swiss chard juice delivers an estimated 1,500+ mcg of vitamin K — more than 1,000% of the daily value.

For most people, this is not a problem. Vitamin K from food sources (as opposed to supplements) has no established upper limit and is well-tolerated.

The exception is people taking warfarin (Coumadin) or other vitamin K–antagonist blood thinners. Swiss chard juice can significantly alter the effectiveness of these medications. If you're on blood thinners, talk to your doctor before adding regular swiss chard juice to your diet — consistency matters more than avoidance, but your prescriber needs to know.

Swiss chard is one of the highest-oxalate vegetables — roughly 645mg per 100g raw, which concentrates in juice. For most healthy people, dietary oxalates are metabolized and excreted without issue. But for people with a history of calcium oxalate kidney stones, or those with hyperoxaluria, high-oxalate greens like swiss chard, spinach, and beet greens are worth limiting.

If you've had a calcium oxalate kidney stone before, your urologist has likely already mentioned high-oxalate foods. Swiss chard juice is not the produce to build a daily protocol around in that case — kale, romaine, and celery are lower-oxalate alternatives.

For people without kidney stone history, 4–6 oz of swiss chard juice per day blended with other produce is a reasonable amount. The nutrient density is exceptional at that quantity without the risk of oxalate accumulation.

Raw swiss chard juice is earthy, slightly bitter, and has a minerally edge — similar to beet greens but without the sweetness. The stems (especially rainbow chard) contribute a mild, slightly sweet note that softens the overall flavor.

It pairs exceptionally well with apple (the most common pairing — sweetness cuts the bitterness directly), carrot, cucumber, lemon, and ginger. Celery adds volume and a light flavor that doesn't clash. Beet is a natural match flavor-wise, though that combination is very high in oxalates, so it's one to use occasionally rather than daily.

Solo swiss chard juice is challenging even for experienced juicers. Starting with a 20–30% chard ratio in a mixed blend is the practical approach for daily use.

Swiss chard juice is more perishable than root vegetable juices. The high chlorophyll content degrades quickly, and the juice can take on an unpleasant taste within 24 hours in a centrifugal-juiced batch.

Cold press or masticating juice retains quality longer due to lower oxidation during extraction — up to 48–72 hours in an airtight container (mason jar filled to the brim) in the refrigerator. Centrifugal juice is best consumed within 24 hours.

For meal prep purposes, mixing swiss chard into a multi-ingredient juice (with carrot, apple, or cucumber) extends palatability slightly, since those juices oxidize more slowly.

Both — but they juice differently. The stems, especially the thick white or colored ribs, are higher in water content and extract efficiently in any juicer type. The leaves are denser and more fibrous, requiring a slow juicer for decent yield.

For masticating and twin gear juicers, feed the whole plant. For centrifugal juicers, the leaves often pass through too quickly for good extraction — rolling them tightly around each other or sandwiching them between stem pieces helps. Some centrifugal users juice the stems separately first, then add the rolled leaves to improve overall yield.

Neither part is wasted in a slow juicer. In a centrifugal machine, expect the leaves to contribute meaningfully less juice than the stems.
