The ZhenXi Orange Vitamin C energy drink is a 500ml canned functional beverage that pairs a bright citrus orange flavor with added vitamin C and B-group vitamins. The 500ml standard can is a convenient on-the-go format for replenishing energy at work, while studying, or during exercise, and the larger fill size differentiates it from the common 250ml and 330ml energy formats on the shelf.

It is produced as an OEM / private-label product, meaning the flavor, formula, can size and full label design can be tailored to your brand. ZhenXi handles raw-material sourcing, formulation, filling, and export under one roof, so distributors and importers can launch their own energy drink line without managing multiple suppliers.

Added vitamin C and B vitamins support the "functional" positioning that buyers in the energy and sports-drink category look for. The exact vitamin levels and any electrolyte, caffeine, sugar or sweetener content can be set to match your target market's labeling rules and consumer preferences.

How to choose an OEM energy drink manufacturer

The right manufacturing partner does more than fill cans. Look for a factory that controls formulation, filling, and can supply in-house, holds the certifications your destination market requires (FDA for the US, relevant EU food-contact and labeling compliance, HALAL for GCC and Muslim-majority markets), and can prove real capacity. Ask for production-base size, number of filling lines, annual output, and a list of countries already served. A supplier that offers free samples, a digital label proof, and a written quotation quickly is signalling that it is set up for export B2B, not just domestic sales.

How energy drink formula development works

A private-label formula is built around four levers: the functional actives (vitamin C, B-group vitamins, taurine, caffeine, electrolytes), the sweetening system (sugar, low-sugar, or sugar-free with stevia/sucralose), the flavor base (here, orange), and the acidity and carbonation profile. Each lever is adjusted to your market's taste expectations and its regulatory limits — for example, several markets cap caffeine content and require specific advisory statements. Share your target market and positioning, and the formulation team proposes a recipe, then refines it through sampling until you approve.

How much caffeine should an energy drink contain?

Caffeine levels vary widely by market and positioning. Many regions reference roughly 32 mg per 100 ml as a common ceiling for energy drinks, and some markets require a "high caffeine content" label above that threshold. Caffeine-free vitamin formulas are also popular where the appeal is hydration and vitamin fortification rather than stimulation. Because the limits differ by country, the caffeine level for your SKU should be set against your specific destination market's rules — we configure it per order.

Vitamin C vs taurine: what each one signals to buyers

Vitamin C (ascorbic acid) positions a drink around immunity, antioxidants, and an everyday "healthy energy" message, and it pairs naturally with a citrus orange flavor. Taurine is associated with the classic high-stimulation energy-drink category and is usually combined with caffeine. Many brands now run both styles: a vitamin-forward line for broader, health-conscious shoppers and a taurine/caffeine line for the traditional energy segment. The 500ml Orange Vitamin C drink sits firmly in the first group.

The vitamin C energy drink market

Demand for "functional" and "better-for-you" energy drinks has grown faster than the traditional high-sugar segment, driven by younger consumers who want energy plus a perceived health benefit. Vitamin-fortified, lower-sugar, and larger single-serve formats (like 500ml) are central to that shift. For importers and private-label brands, a certified OEM partner that can deliver a vitamin C orange drink with flexible sugar and caffeine options is a practical way to enter this growing category without building a factory.
