The Sunshine Vitamin for the Whole Family
Food supplement
Vitamin D3 (cholecalciferol), the biologically active precursor form of vitamin D in the body, plays a key role in numerous physiological functions. Naturally synthesized by the skin under UVB exposure, it is often called the “sunshine vitamin.” However, due to insufficient sunlight—especially in winter—and in highly polluted urban areas where UVB rays struggle to penetrate the atmosphere, 30 to 60% of Europeans are deficient, with rates exceeding 60% among women and the elderly.
Essential for bone and muscle health, vitamin D3 contributes to dental mineralization, the maintenance of normal blood calcium levels, and the proper functioning of the immune system. In children, it supports growth and bone development. A deficiency can lead to fatigue, muscle weakness, bone fragility, and a weakened immune system. Diet and skin synthesis are often insufficient to meet daily needs, making targeted supplementation valuable for maintaining immune function and bone health.
As a fat-soluble vitamin, D3 is more effective than D2 (plant-based). It is naturally sourced from lanolin, a wax extracted from sheep’s wool, which is exposed to UVB rays, mimicking the skin’s natural synthesis process to produce a pure and highly bioavailable form of vitamin D3.
PHYSIOMANCE® D-Nat 1000 is a food supplement formulated with natural vitamin D3. It is delivered in an oily form using cold-pressed organic extra virgin olive oil, ensuring optimal bioavailability, and facilitating absorption and utilization by the body.
Available in capsules, dropper bottle, or spray format, PHYSIOMANCE® D-Nat 1000 is a mono-ingredient supplement, allowing precise and personalized dosing based on individual needs, while avoiding the risk of overdosing. Its natural profile is reinforced: our vitamin D3 is of natural origin, and the extra virgin olive oil is certified organic and obtained through first cold pressing.
PHYSIOMANCE® D-Nat 1000 drop format is free from sweeteners, flavorings, preservatives, and colorants.
The importance of vitamin D3 for the body has been thoroughly evaluated by the European Food Safety Authority (EFSA).

A Natural and Bioavailable Vitamin D3
Laboratoire THERASCIENCE has carefully selected a bioavailable form of vitamin D3 to ensure optimal absorption and assimilation by the body, thereby maximizing its effectiveness.
The vitamin D used in our formulas is natural and provided in the form of cholecalciferol (D3), known for its superior bioavailability and optimal assimilation. This is the same form naturally produced by the skin under UVB exposure. It is more bioavailable than vitamin D2 (ergocalciferol). As a fat-soluble vitamin, D3 is efficiently stored in the body and helps maintain stable vitamin D levels in the bloodstream.
The vitamin D3 used in PHYSIOMANCE® D-Nat 1000 is derived from sheep’s wool, specifically from lanolin, also known as “wool wax.” Vitamin D3 is produced by exposing lanolin to UVB radiation, with wavelengths similar to those of sunlight. This triggers a natural photochemical conversion, mirroring the process that takes place in human skin. The result is vitamin D crystals that no longer contain lanolin residues. Thus, the resulting vitamin D is entirely natural and of high purity.
Natural and Neutral Carrier: Cold-Pressed Organic Olive Oil
To formulate our natural vitamin D3 solutions, we selected a neutral carrier: cold-pressed organic olive oil.
Our cold-pressed organic olive oil provides a natural, high-quality lipid base. This mechanical extraction process, performed without solvents or chemical treatments, preserves the oil’s integrity and physico-chemical properties. Used as a carrier, this oil ensures homogeneous dispersion and better incorporation of the fat-soluble vitamin D3, while also guaranteeing its stability.
Sourced from organic farming and free from undesirable residues, it aligns perfectly with our clean label approach, combining naturalness and safety.
