D-NAT 2000
Food Supplement

Essential for maintaining overall balance, vitamin D3 (cholecalciferol) is naturally synthesized by the skin when exposed to UVB rays. This "sunshine vitamin" is involved in numerous physiological functions. However, in areas with low sunlight exposure or in urban environments, deficiencies are common, affecting 30 to 60% of the population—and even more so among women and the elderly.

Vitamin D3 supports bone strength, dental mineralization, healthy muscle function, and immune system performance. In children, it is vital for growth. A deficiency can result in chronic fatigue, muscle weakness, or reduced immunity.

Dietary intake and endogenous synthesis are often insufficient to meet daily needs. A well-dosed supplement—especially in D3—is therefore valuable, particularly during winter or for at-risk populations.

Vitamin D3, a fat-soluble vitamin, is better absorbed and more effective than D2, which is typically plant-derived. It is extracted from lanolin, a natural wax found in sheep’s wool. This lanolin is then exposed to UV rays, replicating the skin’s natural process. The result is pure vitamin D3 that the body can easily utilize.

Why choose PHYSIOMANCE® D-Nat 2000?

PHYSIOMANCE® D-Nat 2000 provides a dosage of 2000 IU (50 µg) per drop or capsule to meet increased nutritional needs.

The formula is 100% natural. THERASCIENCE Laboratory has selected a natural D3 derived from lanolin, resulting in high-quality, pure, and bioavailable vitamin D3. The oily base uses cold-pressed organic extra virgin olive oil, which optimizes the stability and absorption of the vitamin D3 and aligns with our Clean Label commitment.

Available in capsules or dropper bottle, PHYSIOMANCE® D-Nat 2000 is a mono-ingredient supplement, enabling precise dosage personalization based on individual needs—while avoiding overdosing.

The dropper format contains no sweeteners, flavorings, preservatives, or colorants.

What does science say?

Vitamin D3 has been extensively studied and evaluated by EFSA (European Food Safety Authority). It is scientifically recognized to contribute to:

• Normal functioning of the immune system;

• Maintenance of normal bones and teeth;

• Maintenance of normal muscle function;

• Normal calcium levels in the blood, and normal absorption/utilization of calcium and phosphorus.

These health benefits are essential at all stages of life.

Highly Bioavailable Oil-Based Form

To ensure efficacy, THERASCIENCE Laboratory selected a form of vitamin D3 known for optimal bioavailability. This active form—cholecalciferol—is identical to that naturally produced by the skin in response to sunlight.

Unlike vitamin D2 (ergocalciferol), vitamin D3 has better absorption and is more efficiently stored in the body. As a fat-soluble vitamin, it ensures long-term maintenance of optimal vitamin D levels in the bloodstream.

The D3 in PHYSIOMANCE® D-Nat 2000 is derived from lanolin, a natural wax extracted from sheep’s wool. This lanolin is then exposed to UVB rays, mimicking the body’s natural synthesis process. This triggers a natural photochemical conversion, resulting in highly pure vitamin D3, free from lanolin residues, and ideal for effective, safe supplementation.

Natural, Neutral Carrier: Cold-Pressed Organic Olive Oil

To guarantee both efficacy and quality, the chosen carrier is organic extra virgin olive oil, cold-pressed to maintain its nutritional and chemical integrity.

This mechanical extraction process, free from solvents and chemical treatments, preserves the oil’s full properties. Used as a carrier, it enables a homogeneous dispersion of liposoluble vitamin D3, enhancing its incorporation and stability within the formula.

Sourced from organic farming and free from unwanted residues, this oil aligns with our Clean Label approach, combining naturalness, safety, and performance.
