Product information

The IMPULSE NUTRITION VITAMIN D3 is your ally to help you reach your full potential by strengthening your immunity and your bones.

Immune defenses

Your immune system is your first line of defense. To keep it in tip-top shape, vitamin D is essential. It strengthens your natural defenses against bacteria, viruses and other external stressors. Normally synthesized by your body through sun exposure, vitamin D becomes scarce in winter, when UV rays are lacking. With this vitamin D shot, you're giving your body the support it needs to stay strong and resistant to daily challenges.

Bone health

To perform and endure, your bones must be solid. Vitamin D plays a key role by optimizing the absorption of calcium and phosphorus, minerals essential for bone strength. Adequate vitamin D intake helps reinforce your skeletal structure and reduce the risk of injury, especially under physical strain.

Muscle capacity

Vitamin D is also essential for maintaining optimal muscle function. It supports strength, coordination and power output, helping you move better, push harder and recover faster.

Immunity. Strength. Resistance.

Formulated for rapid absorption and comfortable intake, this vitamin D delivers optimal effectiveness.

Scientific studies

Nature and origin of active ingredients

The vitamin D is a fat-soluble vitamin, which means it dissolves in fats and can be stored in the body. It plays a fundamental role in assimilation of calcium and phosphorus, minerals essential for the formation and maintenance of a strong bone structure. This vitamin is produced naturally by the skin when it is exposed to ultraviolet rays from the sun, a crucial biological process for maintaining sufficient levels throughout the year. In addition to this skin synthesis, vitamin D is also present in certain foods, including oily fish like the salmon or the mackerel, the liver of certain animals, as well as in the egg yolks.

Among the different forms of vitamin D, vitamin D3 (cholecalciferol) is the form closest to that produced naturally by the skin. It is better assimilated and more efficient to increase and maintain blood levels of vitamin D compared to vitamin D2 (ergocalciferol), which makes it a preferred choice for supplementation. Despite this dual natural source, many people experience a vitamin D deficiency, in particular due to an insufficient sun exposure, climatic conditions, lifestyle or even certain physiological factors such as age or skin pigmentation. This is why a targeted vitamin D3 supplementation is often recommended to ensure sufficient intake, avoid deficiencies and preserve the bone and muscle health.

The importance of vitamin D was highlighted at the beginning of the 20th century, when its major role in prevention of rickets, a disease that seriously affected bone growth in children. Today, its interest goes far beyond this initial prevention, extending to the global health, especially among athletes or people exposed to risk factors.
