Gold C Powder, Vitamin C, 1,000 ...
Pros
- ✓Flexible dosing: powder lets you take 250 mg, 500 mg, or 2,000 mg without switching products — impossible with pre-dosed tablets
- ✓Zero other ingredients — pure L-ascorbic acid only, no sweeteners, fillers, or allergens
- ✓250 g yields roughly 250 full servings at 1,000 mg, making the cost-per-gram among the lowest available
- ✓Dissolves quickly in water, juice, collagen powder, or electrolyte drinks per reviewer reports
Cons
- ✗Distinctly sour taste — some reviewers need to mix with juice or honey to make it drinkable; one 3-star reviewer gave up on powder entirely
- ✗Plain ascorbic acid is not buffered or liposomal — at doses above 1,000 mg, loose stools are a known risk not reflected in these reviews
- ✗No independently verified third-party testing confirmed by product specs
Best For
Gold C®, USP-grade Vitamin C, 1,...
Pros
- ✓Stomach-friendly at 1,000 mg — the single most mentioned benefit in reviews, with the majority explicitly noting no acidity or heartburn
- ✓Exceptional value: 240 capsules at one per day is an 8-month supply at a low per-dose cost, praised consistently
- ✓Minimal formula — ascorbic acid, hypromellose capsule, magnesium stearate, no fillers, allergens, or unnecessary additives
- ✓Frequent reviewer reports of fewer colds, faster recovery, and brighter skin from sustained daily use
Cons
- ✗Plain ascorbic acid is the most basic vitamin C form — not liposomal or buffered, which can offer improved tolerance or bioavailability for some people
- ✗No verified third-party testing per product specs — quality assurance relies on the manufacturer's own testing processes
- ✗At least one reviewer finds the capsules on the large side, though most describe them as easy to swallow
- ✗A handful of reviewers notice only subtle or delayed effects, particularly in the first few weeks

What does the data say about Gold C Powder, Vitamin... vs Gold C®, USP-grade Vit...?
Both products share the same California Gold Nutrition formula at their core: plain L-ascorbic acid, no buffers, no liposomal coating, no extras. The difference is purely in format. Gold C® capsules deliver a fixed 1,000 mg per veggie capsule — ascorbic acid, hypromellose, magnesium stearate, nothing else. The powder is even simpler: pure L-ascorbic acid and that is it. Because of that purity difference, the capsules score slightly higher on ingredient quality (75/100 versus 71/100), though both land at 76/100 overall and 78/100 for effectiveness. On price, the powder wins clearly — £8.16 for 250 g versus £15.39 for 240 capsules, giving it a value score of 91/100 against the capsules' 89/100.
The capsules make sense if you want a pre-measured daily dose and have had stomach trouble with vitamin C before. Reviews consistently flag them as easy on the gut at 1,000 mg, which is not something every ascorbic acid supplement can claim. The powder suits anyone who wants control over their dose — you can take 250 mg or 2,000 mg without buying a separate product. It is also the obvious pick if large capsules are hard to swallow, or if you are pairing vitamin C with collagen and want to mix them into one drink.
The powder's one real drawback is taste. L-ascorbic acid is sour, and some reviewers find it unpleasant enough to need juice or honey to get it down — one gave up on it entirely. The capsules sidestep that problem completely. Worth noting: both forms carry the same warning about high doses and digestive sensitivity, so going above 1,000 mg on the powder carries a known loose-stool risk.
Pure L-ascorbic acid at 1,000 mg per scoop, with absolutely nothing else added — no fillers, no flavours, no binders.
