Metabolic Nutrition | Elderberry + C Zinc | 90 Capsules

Metabolic Nutrition Elderberry with Vitamin C and Zinc is a simple, three-active immune support formula built around a clear formulation idea: combine a high-input elderberry dose with two of the most established micronutrients for immune function. This is not a trendy, overcomplicated “wellness blend.” It is a capsule-based daily support product designed to cover botanical antioxidant support, foundational vitamin support, and a clinically relevant zinc dose in one serving.

The formula starts with 1,200mg of black elderberry (Sambucus nigra) fruit. Elderberry is widely used for immune support because it is naturally rich in anthocyanins and other polyphenols that contribute antioxidant activity and help defend cells from oxidative stress during periods of higher immune demand. From a user-experience standpoint, elderberry is not a “feel it in 20 minutes” ingredient. What it offers is a consistent nutritional and botanical layer of support that fits best with daily use, especially during seasonal stress, travel, or periods of high social exposure. The main limitation is transparency around standardization: we know the dose, but not the anthocyanin standardization. That matters because standardized extracts make it easier to compare potency across products. Even so, 1,200mg is a substantial inclusion for a straightforward elderberry formula.

Vitamin C is included at 150mg as ascorbic acid. That is not a megadose, and it does not need to be. Vitamin C supports immune cell function, antioxidant defense, and collagen-related tissue maintenance, while also pairing well with zinc in immune-support formulas. At 150mg, this sits comfortably above the daily requirement for most adults and works as a practical daily support dose rather than an aggressive standalone protocol. In this formula, vitamin C’s role is less about being the star and more about strengthening the overall system.

Zinc is the most clinically anchored ingredient here from an evidence perspective. At 30mg, this formula lands squarely within the researched 11–45mg clinical dose range. Zinc is an essential trace mineral required for the catalytic activity of hundreds of enzymes and plays a central role in immune function, cellular metabolism, DNA and protein synthesis, cell division, antioxidant defense, wound healing, and maintenance of taste and smell. It is one of the best-studied immune-support nutrients in the category, supported by 68 trials, 12 meta-analyses, and over 100,000 participants, with strong evidence for helping reduce risk and duration of acute respiratory infections. The source blend—oxide, citrate, and gluconate—suggests a multi-form approach, though the exact breakdown is not disclosed.

The synergy here is rational and clean. Elderberry contributes botanical antioxidant and seasonal wellness support. Vitamin C reinforces antioxidant protection and complements zinc. Zinc provides the most robust immune-function backbone in the formula. Together, they cover three different but overlapping angles: plant polyphenols, antioxidant vitamin support, and essential mineral support.

Transparency is solid in one important way: this is not a proprietary blend. You can see each active and its dose. That is a meaningful advantage in a category full of vague “immune matrices.” The main transparency gap is the lack of elderberry standardization and the unspecified ratio of the zinc forms.

What should you expect? On day 1, probably nothing dramatic—and that is normal. This is a daily wellness formula, not a stimulant. Over 2 to 4 weeks of consistent use, the value is in maintaining reliable nutrient coverage and immune support, especially if your diet, schedule, travel, sleep, or seasonal environment make consistency hard to achieve through food alone.
