D3 + K2 + Citrus
Bioflavonoids

The citrus groves of Valencia and Sicily represent centuries of cultivation expertise. These regions produce oranges and lemons with exceptionally high bioflavonoid concentrations due to the Mediterranean climate, volcanic soil conditions, and traditional growing methods that prioritize fruit quality over yield.

Our Spanish and Italian processing partners use whole-peel methods that capture the complete bioflavonoid profile: hesperidin, naringenin, nobiletin, and diosmin. This differs from synthetic isolation methods that target individual compounds. Research suggests that these bioflavonoids work synergistically with vitamin C and may have enhanced bioavailability when consumed as part of their natural citrus matrix.

Each shipment from our Mediterranean partners includes detailed harvest documentation, soil analysis reports, and bioflavonoid concentration certificates. The processors provide HPLC standardization data for every batch, ensuring consistent compound levels that match published research specifications.

Our manufacturing process begins in Mediterranean citrus groves during peak harvest season. Spanish and Italian partners select fruit at optimal ripeness when bioflavonoid concentrations reach their highest levels. The whole-peel processing occurs within hours of harvest to preserve compound stability.

Lichen-sourced vitamin D3 comes from specialized cultivation facilities that grow lichen in controlled environments, ensuring consistent cholecalciferol production without animal-derived ingredients. The natto fermentation for our MK-7 follows traditional Japanese methods, using specific bacterial strains that produce the longest-chain menaquinone form.

All raw materials undergo identity testing, potency verification, and purity analysis before entering our Brazilian facility. The encapsulation process uses pharmaceutical-grade equipment in climate-controlled environments to maintain compound stability.

The Mediterranean climate provides ideal conditions for citrus cultivation, with hot, dry summers and mild, wet winters that concentrate bioflavonoid production in citrus peels. Spanish Valencia oranges and Italian lemons grown in these conditions typically contain higher hesperidin and naringenin levels than citrus grown in other climates.

Volcanic soil in Sicily contributes additional mineral content that appears to enhance bioflavonoid synthesis in citrus trees. Soil analysis from our Italian suppliers shows elevated levels of potassium, magnesium, and trace minerals that research has linked to increased secondary metabolite production in citrus fruit.

Traditional cultivation methods in these regions avoid intensive agricultural practices that can reduce bioflavonoid concentrations. Our Spanish and Italian partners use minimal irrigation, allowing trees to develop deeper root systems that access natural soil nutrients.

Harvest timing plays a crucial role in bioflavonoid concentration. Our partners harvest citrus at peak ripeness when compound levels reach their maximum, then process the peels immediately to preserve compound stability and prevent degradation.
