FAQ
Q: How do orange bioflavonoids work as antioxidants?
A: Fruit bioflavonoids, which include hesperidin, quercetin, and other flavonoid compounds, neutralize free radicals by giving them an electron. Respiratory oxygen species are kept stable by their chemical makeup, which protects cells from oxidative stress. Multi-compound antioxidants cover more areas than single-molecule antioxidants.
Q: Are citrus bioflavonoids compatible with other substances?
A: Certain chemicals in citrus fruits (bioflavonoids) do work well with other antioxidants like vitamin C and vitamin E. Combining them with quercetin, resveratrol, or astaxanthin makes full antioxidant mixtures. As needed, our technical team can give you advice on compatibility for your specific formulation needs.
Q: What is the recommended storage quantity and how long should it be kept?
A: At room temperature, kept dry, and out of direct sunlight, our orange bioflavonoid powder stays effective for 24 months. Maintaining temperatures below 25°C is what we suggest for sealed storage in the original packaging. Adequate keeping stops products from absorbing water and oxidizing, which could lower their quality.
Q: Do you provide samples for formulation testing?
A: Yes, definitely. Minimum order quantities start at 1 kg, and smaller sample sizes can be provided for initial formulation tests. Federal Express delivers samples to most foreign locations in three to five business days. Therefore, you can check the quality before placing larger orders.
