Strawberry Juice Powder (Fragaria × ananassa)
Strawberry Juice Powder is a dietary supplement produced from the fruit of the cultivated strawberry, Fragaria × ananassa. The powder is typically made by freeze-drying fresh strawberries and then grinding them into a fine powder. This process helps to preserve the fruit’s rich nutritional profile and its vibrant color and flavor. Strawberry powder serves as a concentrated source of the vitamins, minerals, and potent bioactive compounds found in the fresh fruit, making it a convenient nutritional supplement [1].
Strawberries have been consumed for thousands of years and are celebrated not only for their taste but also for their health-promoting properties. As a supplement, the powder offers an easy way to incorporate the benefits of strawberries into the diet, especially for individuals who may not consume the recommended daily amount of fruit [1]. It can be added to smoothies, yogurts, desserts, and other foods.

Key Bioactive Compounds
Strawberries are a powerhouse of beneficial plant compounds, with some of the highest antioxidant levels among fruits.
- Anthocyanins: Strawberries contain over 25 different anthocyanins, with pelargonidin being the most abundant. These compounds are responsible for the fruit’s bright red color and are powerful antioxidants linked to numerous health benefits, particularly for heart health [3].
- Ellagic Acid and Ellagitannins: Strawberries are a primary source of these polyphenol antioxidants. Ellagitannins, such as sanguiin H-6, are converted to ellagic acid in the gut. These compounds have been studied for their potential to fight bacteria and reduce the risk of certain cancers [3].
- Vitamin C: Strawberries are an excellent source of Vitamin C, a vital antioxidant that supports immune function and skin health [3].
Health Benefits
Epidemiological and clinical studies suggest that regular consumption of strawberries, including in powdered form, can have beneficial effects on several aspects of health, primarily due to their high antioxidant and anti-inflammatory capacity.
Cardiovascular Health
One of the most significant benefits of strawberry consumption is its positive impact on cardiovascular health. The flavonoids and antioxidants in strawberries help reduce oxidative stress and inflammation, which are key drivers of heart disease.
A 2009 study published in the Nutrition Journal investigated the effects of 50g of freeze-dried strawberry powder daily in women with metabolic syndrome. After four weeks, the participants showed a significant decrease in total cholesterol (-5%) and LDL ("bad") cholesterol (-6%), as well as a 14% reduction in markers of lipid peroxidation, a form of oxidative stress [1].
These effects are attributed to the high concentration of polyphenolic flavonoids, fiber, and phytosterols in the strawberry powder [1].
Antioxidant and Anti-inflammatory Effects
Strawberries are consistently ranked among the fruits with the highest antioxidant content, with levels 2–11 times greater than other fruits [3]. The powerful combination of Vitamin C, anthocyanins, and ellagic acid helps the body combat cellular damage from free radicals. This potent antioxidant activity may help reduce the risk of chronic diseases, including heart disease and cancer [2, 3].
Cognitive Health and Mood
Emerging research suggests that strawberry supplementation may also benefit brain health. A 2023 study found that daily supplementation with whole-fruit strawberry powder positively impacted memory and mood in middle-aged, overweight adults.
Dosage and Usage
There is no official recommended dosage for strawberry juice powder, but clinical studies provide some guidance.
- Freeze-dried Strawberry Powder: Dosages in clinical studies have ranged from 10 to 60 grams per day for up to 6 months [2].
- Equivalency: In these studies, 1 gram of freeze-dried strawberry powder was considered equivalent to approximately 10 grams of fresh strawberries [2]. A daily dose of 50 grams of powder, as used in the Basu et al. study, is equivalent to about 500 grams (or roughly 3 cups) of fresh strawberries [1].
Safety and Precautions
Strawberry powder is generally considered safe for consumption, and no adverse events were reported in clinical studies with supplementation for 6 to 12 weeks [2]. However, some considerations are important.
- Allergies: Strawberry allergy is one of the more common fruit allergies. Symptoms can include itching and dermatitis. Individuals with a known allergy to birch pollen may experience cross-sensitivity to strawberries. The allergen responsible, Fra a 1, is found in red ripe strawberries but not in the white-fruited genotype, which may be tolerated by allergic individuals [2].
- Pregnancy and Lactation: While strawberries are safe as part of a normal diet, information regarding the safety and efficacy of high-dose supplementation during pregnancy and lactation is lacking. It is best to consult a healthcare provider [2].
Drug Interactions
- None well documented. There are no well-documented interactions between strawberries and medications [2].
