Sea Buckthorn Vitamin C Label Checker
Honest vitamin C bands for every sea buckthorn form: berries, juice, dried, powder, and oil, compared with oranges and daily needs.
That is 222 to 667% of a 90 mg daily target, or about 2.9 to 8.6 oranges.
The full published range, 200 to 600 mg per 100 g. Variety, altitude, and ripeness decide where a batch lands.
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.
The bands, per 100 g or 100 ml
| Form | Low | Typical | High | What moves the number |
|---|---|---|---|---|
| Fresh berries | 200 mg | 400 mg | 600 mg | The full published range, 200 to 600 mg per 100 g. Variety, altitude, and ripeness decide where a batch lands. |
| Frozen berries | 180 mg | 380 mg | 580 mg | Freezing pauses the vitamin C clock. Properly frozen berries keep nearly everything; a little is lost in thawing drip. |
| Pure juice, recently bottled | 100 mg | 250 mg | 450 mg | Pressing costs only 5 to 11 percent in measured production, but heat and shelf time keep taxing it. A distant best-by date wins. |
| Nectar or juice blend | 20 mg | 60 mg | 150 mg | Many bottles are mostly apple or grape juice. If sea buckthorn is not first on the ingredient list, assume the low end. |
| Dried berries | 50 mg | 120 mg | 300 mg | Heavy losses to heat, oxygen, and time, partly offset by weight concentration. Freeze-dried keeps far more than air-dried. |
| Berry powder | 40 mg | 100 mg | 250 mg | Varies by drying heat more than any other form. The label's vitamin C line beats any table, including ours. |
| 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: variety, altitude, ripeness, and test method swing the result several-fold, and processing keeps taxing it. Any source quoting one heroic figure is cherry-picking. Bands follow Gutzeit 2008 and Teleszko 2015, the same sources as our vitamin C page. The daily target is 75 mg for adult women and 90 mg for adult men; 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 comparisonshows what else each form keeps or loses.
