Combat vitamin D deficiency with 4FRESH Health Vitamin D3 (cholecalciferol), a crucial nutrient supporting numerous bodily functions. Studies show that up to 80% of Russians experience vitamin D deficiency. Our sublingual tablets deliver 2000 IU of Vitamin D3 directly into the bloodstream for superior absorption and rapid action. This optimal dosage helps maintain healthy vitamin D levels, alleviating symptoms such as insomnia, nervous disorders, apathy, fatigue, joint pain, muscle aches, and poor posture often associated with deficiency.
Addressing vitamin D deficiency can significantly improve your overall health, combating frequent illnesses, chronic fatigue, poor memory and concentration, weight gain, and weakened bones and teeth. Vitamin D3 also enhances calcium and phosphorus absorption, crucial for adults. It strengthens the immune system, improving resistance to disease and reducing illness severity and duration, and lowering the risk of osteoporosis.
Beyond immune support, Vitamin D3 plays a key role in dopamine synthesis, regulating mood, reducing the risk of depression and anxiety, and improving sleep quality. Note that vitamin D3 increases magnesium usage; therefore, concurrent intake is recommended.
