Bone Nutrient Essential Complex Women dōTERRA | 120 capsules

Extra virgin olive oil is obtained by simple mechanical pressing, cold, with no solvent and no heating. It is this absence of treatment that leaves it its olive taste and its polyphenols. Here it serves as a carrier for the ingredients that dissolve only in a fatty medium.

As ascorbic acid, vitamin C is a white, highly soluble and distinctly acidic powder: the very molecule found in citrus fruit. It breaks down with light, heat and air, which calls for tightly closed packaging.

Vitamin D comes in two forms: cholecalciferol, drawn from the lanolin of sheep's wool grease, and ergocalciferol, obtained from yeasts exposed to ultraviolet light. Both are fat-soluble, dissolving only in a fatty medium. Hence their presence in oil-based capsules.

Also called vitamin B8, or H depending on the nomenclature, biotin is a small sulphur-bearing molecule found naturally in egg yolk and liver. The one used in supplements is made by synthesis, the surest route to a constant purity. It appears in formulas in minute quantity.

The calcium used here comes from fossilised coral gathered from the ground, a source naturally rich in calcium carbonate and marine trace elements. Its very fine grind makes it easy to encapsulate. It is the bulkiest ingredient of the formula, which explains the number of capsules per serving.
