D-NAT 1000
Dietary Supplement
PHYSIOMANCE® D-Nat 1000 is a dietary supplement formulated with natural vitamin D3 (cholecalciferol)—the biologically active precursor form of vitamin D in the body. Commonly known as the "sunshine vitamin", it is naturally synthesized in the skin under UVB exposure.
However, due to limited sunlight—especially in winter or in heavily polluted urban areas where UVB rays have difficulty penetrating the atmosphere—30 to 60% of Europeans are deficient in vitamin D, and the rate exceeds 60% among women and the elderly.
Vitamin D3 plays a key role in numerous physiological functions:
Supports bone and muscle health
Contributes to dental mineralization
Helps maintain normal calcium levels
Supports the immune system
In children, it supports bone growth and development
Deficiency in vitamin D3 can lead to fatigue, muscle weakness, bone fragility, and reduced immune defenses.
Diet alone and skin synthesis often aren’t sufficient to meet daily needs, making targeted supplementation necessary to maintain bone health and immunity.
Contains natural vitamin D3 obtained from lanolin, a wax extracted from sheep’s wool and exposed to UVB rays to mimic natural human synthesis. The resulting D3 is highly pure and fully bioavailable.
Delivered in organic extra virgin olive oil (first cold press) to ensure optimal bioavailability and efficient absorption.
Available in capsules, drops, or spray, this mono-ingredient formula allows precise, personalized dosing and avoids overdosing.
The drop format is free from sweeteners, flavorings, preservatives, and colorings.
The European Food Safety Authority (EFSA) recognizes the following benefits of vitamin D3:
Supports the normal function of the immune system
Helps maintain healthy bones and teeth
Aids normal muscle function
Contributes to normal calcium levels and promotes the absorption and utilization of calcium and phosphorus
These effects are essential at every stage of life.
Laboratoire THERASCIENCE carefully selected a bioavailable form of vitamin D3 for optimal absorption and effectiveness. This natural cholecalciferol (D3) form mimics the one produced by the skin under UVB rays. It is liposoluble, allowing it to be efficiently stored and maintain stable levels in the blood.
The D3 used in PHYSIOMANCE® D-Nat 1000 is produced from lanolin, or “wool wax,” by exposing it to UVB radiation that mimics solar rays. This photo-conversion process is similar to what happens in human skin, yielding high-purity crystals of vitamin D3, free of lanolin residues.
We selected organic extra virgin olive oil (first cold press) as a neutral lipid carrier:
Ensures natural lipid support for better D3 absorption
Mechanical extraction, free from solvents and chemical processing
Preserves the oil’s natural integrity and ensures homogeneous dispersion and stability of vitamin D3
Free of undesirable residues and aligned with our Clean Label approach: combining natural origin and safety
Laboratoire THERASCIENCE offers a range of mono-ingredient formulations to provide:
Personalized supplementation tailored to individual needs
Precise, targeted actions
No risk of overdose in vitamins, minerals, or trace elements
Thanks to its versatile dosage forms, PHYSIOMANCE® D-Nat 1000 is suitable for all ages:
Drops from age 3
Capsules for adults
It provides 1000 IU (25 μg) of vitamin D3 per drop, equivalent to 500% of the daily reference intake.
A simple daily routine that helps meet the vitamin D needs of children (for growth) and adults (for immunity and bone health).
The strength of your immune system helps fight off bacterial and viral infections.
A study published in 2010 showed a 42% reduction in flu cases among people supplemented with vitamin D during the 4 winter months.
Food supplements should not replace a varied and balanced diet.
