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
Ester-C 1000mg Vitamin C 90 Capsules

- ✓Strong immune support reported by reviewers, including use at onset of cold symptoms
- ✓Reputable Solgar brand with a long track record of quality supplements
- ✓Contains natural bioflavonoids which enhance vitamin C bioavailability
Cons
- ✗Large pill size — multiple reviewers struggle to swallow and must break or grind tablets
- ✗Not suitable for vegetarians or vegans (contains non-plant-based capsule material)
- ✗No third-party testing certification (e.g. NSF, Informed Sport) disclosed
- ✗Premium price point compared to standard ascorbic acid alternatives

What does the data say about Gold C Powder, Vitamin... vs Ester-C 1000mg Vitamin...?
Gold C Powder from California Gold Nutrition edges out Solgar's Ester-C 1000mg Vitamin C with an overall score of 76/100 against 74/100. The two differ sharply in form and makeup. Gold C comes as a pure 1,000 mg L-ascorbic acid powder in a 250 g tub that delivers around 250 servings at full dose. You mix your own amount from 250 mg up to 2,000 mg. Ester-C uses a pH-neutral form packed into 90 capsules each holding 1,000 mg. Effectiveness scores tie at 78/100 yet ingredient quality favours Solgar at 83/100 over Gold C's 71/100.
Pick Gold C if you want top value at £8.16 and need flexible dosing for pairing with collagen or filling gaps in a low-fruit diet. The powder suits anyone who dislikes swallowing big pills. Choose Ester-C for sensitive stomachs that react badly to regular ascorbic acid or if you trust the Solgar name for steady immune support during cold season. Its higher price of £22.94 reflects the gentler formula but hurts the value score which lands at 65/100 compared with Gold C's 91/100.
Practical issues matter too. Gold C tastes sharply sour so many stir it into juice. Ester-C capsules run large and some users grind them up. The capsules contain non-plant material which rules them out for vegans. Gold C has zero extra ingredients and avoids that problem entirely.
Pure L-ascorbic acid at 1,000 mg per scoop, with absolutely nothing else added — no fillers, no flavours, no binders.
