Sea Buckthorn Vitamin C Label Checker
Vitamin C in sea buckthorn berries, juice and oil next to oranges, and why dried, powder and frozen forms get no number from us.
Your result
That is 59 to 444% of a 90 mg daily target, or about 0.8 to 5.7 oranges.
Teleszko 2015 measured about 53 to 131 mg per 100 g across eight cultivars of the mongolica subspecies, and Gutzeit 2008 reported about 400 mg per 100 g in the rhamnoides subspecies. The middle figure is only the midpoint of 53 and 400, not an average of anything measured: the two subspecies sit far apart.
Enter a number from 1 to 2000.
Zero. Vitamin C is water-soluble, so it stays in the juice fraction when the berry is pressed. Berry oil and seed oil alike carry essentially none, which is why an oil capsule is the wrong product if vitamin C is your goal. Oil earns its place on omega-7 and the fat-soluble compounds instead.
What we can put a number on, per 100 g or 100 ml
Milligrams = the band for 100 g or ml × your amount ÷ 100. Share of the daily target = milligrams ÷ 90 mg. Oranges = milligrams ÷ 70 mg.
The bar under a form shows its band on one scale, from the low figure to the high one, and the tick marks the midpoint.
| Form | Low | Midpoint of the range | High | What moves the number |
|---|---|---|---|---|
| Fresh berries | 53 mg | 227 mg | 400 mg | Teleszko 2015 measured about 53 to 131 mg per 100 g across eight cultivars of the mongolica subspecies, and Gutzeit 2008 reported about 400 mg per 100 g in the rhamnoides subspecies. The middle figure is only the midpoint of 53 and 400, not an average of anything measured: the two subspecies sit far apart. |
| Frozen berries | No published figure we trust | Storage time and temperature change how much vitamin C survives, and none of our sources measured frozen berries. If the pack states a vitamin C figure, use that one. | ||
| Pure juice, recently bottled | 29 mg | 103 mg | 176 mg | Tiitinen 2005 measured 29 to 176 mg per 100 ml in juice from seven varieties. Gutzeit 2008 found about 5 to 11 percent lost in industrial juice production and about 11 to 12 percent after 7 days at 6 C. A distant best-by date wins. The middle figure is only the midpoint of 29 and 176, not a measured typical juice. |
| Nectar or juice blend | No published figure we trust | Many bottles are mostly apple or grape juice, so the share of sea buckthorn on the ingredient list decides the number, and none of our sources measured blends. If the label states vitamin C, use that one. | ||
| Dried berries | No published figure we trust | Drying and storage can cost vitamin C, and none of our sources measured dried berries, so the size of the loss is not known. If the label states vitamin C, use that figure. | ||
| Berry powder | No published figure we trust | Drying heat and storage can cost vitamin C, and none of our sources measured powders, so the size of the loss is not known. If the label states vitamin C, use that one. | ||
| Oil or oil capsules | 0 mg | 0 mg | 0 mg | Vitamin C is water-soluble. It stays in the juice fraction, so berry oil and seed oil alike contain essentially none. |
Why bands and not one number: subspecies and cultivar differ several-fold in the analyses we cite, and harvest date, altitude and test method are further reasons a figure can differ. Processing and storage can cost some more. Any source quoting one heroic figure is cherry-picking. The fresh-berry band follows Gutzeit 2008 and Teleszko 2015 and the pure-juice band follows Tiitinen 2005, the same sources as our vitamin C page. Frozen berries, blends, dried berries and powder show no band at all: none of those sources measured them, and a figure scaled from the fresh band would be invented. If a label states vitamin C, that figure beats any table here. The daily target is 75 mg for adult women and 90 mg for adult men, and we divide by 90 so the percentage is the conservative one. One medium orange is about 70 mg.
The processing story behind these bands is on the vitamin C page, and the form comparison shows what else each form keeps or loses.
