Organic Strawberry
Also known as: Strawberry, Fragaria x ananassa
Overview
Strawberries (Fragaria x ananassa) are a widely consumed fruit celebrated for their rich nutritional profile, including high levels of vitamin C, folate, and various antioxidants. As a dietary supplement, strawberries are explored for their potential health benefits, particularly in supporting cardiovascular health and enhancing antioxidant capacity. Research suggests that regular strawberry consumption or supplementation may positively influence cardiovascular risk factors by reducing oxidative stress and inflammation. Strawberries contain bioactive compounds such as anthocyanins, ellagic acid, and other flavonoids, which contribute to their health-promoting properties. They are available in various forms, including fresh fruit, freeze-dried powders, extracts, and as ingredients in fortified foods. While generally recognized as safe, it's important to consider individual sensitivities and potential allergic reactions. Further research is needed to fully elucidate the extent and consistency of these benefits across diverse populations.
Benefits
Strawberry supplementation has demonstrated potential benefits in several areas. Studies suggest that it can decrease circulating oxidized LDL, malondialdehyde, C-reactive protein, total cholesterol, and diastolic blood pressure, indicating a positive impact on cardiovascular health. However, some studies also indicate a potential increase in fasting blood sugar levels. Strawberries may also enhance the antioxidant potential of LDL and increase serum levels of vitamin C and folate. These benefits are generally observed in healthy individuals and those at risk for cardiovascular diseases. The effect sizes vary, but significant reductions in cardiovascular risk factors have been noted in several studies. The benefits are typically observed within a few hours to days after consumption, particularly concerning antioxidant effects and vitamin C/folate levels.
How it works
Strawberries exert their beneficial effects through multiple biological pathways. Primarily, they act as antioxidants, neutralizing free radicals and reducing oxidative stress, which is a key factor in cardiovascular disease and aging. The anti-inflammatory properties of strawberries also contribute to their health benefits by modulating inflammatory responses in the body. These effects are mediated by bioactive compounds like anthocyanins and ellagic acid, which target signaling pathways involved in inflammation and oxidative stress. Strawberries interact with the cardiovascular system by improving lipid profiles and reducing blood pressure. The bioavailability of strawberry nutrients is generally good, with significant increases in serum vitamin C and folate observed after consumption, facilitating their systemic effects.
Side effects
Strawberries are generally considered safe for most individuals when consumed in typical dietary amounts. Common side effects are rare, but some individuals may experience allergic reactions, particularly those with sensitivities to other fruits in the Rosaceae family. Symptoms of an allergic reaction can include skin rashes, itching, swelling, or gastrointestinal upset. Uncommon side effects may include mild gastrointestinal discomfort, such as bloating or diarrhea, especially with high consumption. There are no significant drug interactions reported, but individuals taking medications should consult with a healthcare provider to ensure there are no potential contraindications. Pregnant or breastfeeding women should consult healthcare providers before using strawberry supplements, although strawberries are generally safe in food form. Individuals with known fruit allergies should exercise caution.
Dosage
The optimal dosage of strawberry supplements varies depending on the form and the intended health benefit. Typically, studies involve consuming strawberry extracts or freeze-dried strawberries in amounts equivalent to one serving of fresh strawberries per day. There is no established minimum effective dose, and studies vary in dosage. The maximum safe dose is not definitively established, but strawberries are generally considered safe in typical dietary amounts. Strawberry supplements can be consumed at any time of day. Freeze-dried or extract forms may be more convenient for supplementation. Bioavailability is generally good but may vary based on preparation and individual factors. No specific cofactors are required for strawberry supplementation.
FAQs
How often should I consume strawberry supplements?
There is no established frequency, but daily consumption is common in studies investigating cardiovascular benefits and antioxidant effects. Consistency is likely more important than precise timing.
Are strawberry supplements safe for everyone?
Generally safe, but individuals with fruit allergies or specific health concerns should consult a healthcare provider before starting supplementation to avoid potential adverse reactions.
Can I take strawberry supplements with other medications?
There are no known significant interactions, but consulting a healthcare provider is always recommended to ensure compatibility with existing medications and health conditions.
What benefits can I expect from strawberry supplements?
Potential benefits include improvements in cardiovascular health markers, such as reduced cholesterol and blood pressure, and enhanced antioxidant status, contributing to overall well-being.
Are strawberry supplements a cure for diseases?
No, strawberry supplements are not a cure for any disease. They may offer supportive health benefits, but they should not replace conventional medical treatments or a balanced diet.

- https://pubmed.ncbi.nlm.nih.gov/31637390/ – A systematic review and meta-analysis of 14 clinical trials (20 groups) found that strawberry supplementation decreased several cardiovascular risk factors, including oxidized LDL and total cholesterol. The study highlights the potential of strawberries in improving cardiovascular health, but notes the need for larger, longer-term studies to confirm these findings due to variability in study design and duration.
- https://www.tandfonline.com/doi/full/10.1080/07315724.2021.2014369 – A randomized double-blind controlled trial indicated that low-dose strawberry supplementation reduced total cholesterol compared to control and high-dose groups. While the RCT design suggests high quality, the abstract lacks specific details on sample size and duration, limiting the ability to fully assess the study's strength and generalizability.
