Strawberry Juice Concentrate

Also known as: Strawberry, Strawberry Juice Concentrate, Fragaria x ananassa

Overview

Strawberry juice concentrate is derived from strawberries (*Fragaria x ananassa*), a fruit rich in vitamin C, folate, and polyphenols like anthocyanins and ellagitannins. It is primarily used for its antioxidant properties, potential cardiovascular benefits, and as a dietary supplement to enhance nutrient intake. Key characteristics include high levels of antioxidants, flavonoids, and phenolic acids. Research maturity is moderate, with several clinical trials but limited systematic reviews. The quality of available evidence is variable, with some well-designed RCTs but a need for more comprehensive meta-analyses. It is available in various forms, including juice concentrate and whole fruit.

Benefits

Strawberry juice concentrate primarily enhances antioxidant capacity and increases serum levels of vitamin C and folate. Studies show it can improve LDL antioxidant potential, potentially reducing cardiovascular risk factors. Secondary benefits include cardiovascular health improvements, such as lowering total and LDL cholesterol in some populations, and inflammation reduction as part of broader fruit and vegetable concentrates. These benefits are particularly relevant for individuals with low fruit intake or those seeking to enhance their antioxidant status. Observed effects include moderate improvements in antioxidant capacity and vitamin levels, with clinical significance varying by population. Acute effects are seen within hours, while long-term benefits require further study.

How it works

Strawberry juice concentrate works primarily through antioxidant pathways, enhancing LDL resistance to oxidation. It interacts with the cardiovascular and immune systems, targeting LDL particles and antioxidant enzymes. The high bioavailability of folate from strawberries contributes to its effectiveness. The polyphenols, such as anthocyanins and ellagitannins, play a key role in reducing oxidative stress and inflammation. These compounds neutralize free radicals, protecting cells from damage and supporting overall health.

Side effects

Strawberry juice concentrate is generally considered safe when consumed in moderation. Common side effects are not reported in the literature for moderate consumption. Uncommon side effects may include potential gastrointestinal upset in sensitive individuals. Rare side effects include allergic reactions, which are possible but infrequent. No significant drug interactions have been reported. Contraindications include allergies to strawberries. Pregnant or breastfeeding women should consult healthcare providers before use. Overall, it is important to monitor for any adverse reactions and discontinue use if they occur.

Dosage

The minimum effective dose of strawberry juice concentrate is not well established, but it is typically used in amounts providing 100-500 mg of polyphenols. Optimal dosage ranges vary, often as part of broader fruit and vegetable concentrates. The maximum safe dose is not established, but high doses may cause gastrointestinal upset. It can be consumed at any time, potentially beneficial with meals. Available forms include juice concentrate or whole fruit, with bioavailability enhanced through whole fruit consumption. No specific cofactors are required.
