Active Ingredients & Science

Vitamin D3 (Cholecalciferol) – 4000IU per dose

Vitamin D3, also known as cholecalciferol, is the most biologically active form of vitamin D and the form the body naturally produces when the skin is exposed to sunlight. In this formulation, 4000IU (100 micrograms) is delivered per daily dose, which is a potent amount far exceeding the minimal daily requirement for most adults.

Cholecalciferol is a fat-soluble vitamin absorbed in the small intestine and transported to the liver, where it is converted to 25-hydroxyvitamin D, the form used to measure the body's D3 status. From the liver, it is transported to the kidneys, where it is converted to the active hormone form 1,25-dihydroxyvitamin D, which regulates calcium and phosphate balance in the body.

Vitamin D3 plays a central role in several physiological processes. It contributes to the normal function of the immune system by supporting the development and function of T cells and B cells. Vitamin D3 is also essential for normal calcium absorption in the small intestine and for maintaining normal blood calcium levels, which is critical for bone health and muscle contractions. Additionally, vitamin D3 contributes to normal muscle function and plays a role in cell division processes.

The high dose of 4000IU makes this product particularly suitable for people living at high latitudes, with limited sun exposure, or who need a powerful supplement to maintain optimal D3 levels during darker seasons. Cholecalciferol is also the form preferred by many researchers for supplementation because it is the most stable and has the longest half-life in the body.

Gelatin (Capsule Material)

The capsule is made from gelatin, a classic and well-established capsule material that has been used in the dietary supplement industry for decades. Gelatin is a protein-rich substance that is easy to digest in the gastrointestinal tract and allows rapid release of the active content. Gelatin is also hypoallergenic for most people and offers a stable, long-lasting storage solution for sensitive ingredients such as vitamin D3.

Glycerol (Humectant)

Glycerol is a naturally occurring polyol that acts as a humectant in this formulation. It helps maintain optimal moisture within the capsule, ensuring that vitamin D3 remains stable and potent throughout the product's shelf life. Glycerol is also well tolerated by the body and is easily absorbed in the small intestine.

Benefits & Uses

Support for Bone Health and Strength

Vitamin D3 is one of the most important nutrients for long-term bone health. It contributes to normal calcium absorption in the small intestine, which is essential for the body to build and maintain bones. This high dose of 4000IU is particularly valuable for older adults, menopausal women, and other groups at increased risk of bone weakness. By ensuring adequate D3 supply, you can support your bone density and structure over time.

Immune System Support Year-Round

Vitamin D3 plays a crucial role in immune system function. It contributes to the normal function of the immune system by regulating both innate and adaptive immune responses. During autumn and winter, when sun exposure is minimal and D3 production in the skin decreases dramatically, a supplement like this can be especially valuable for maintaining immune function. Consistent D3 supply year-round can help support your body's natural defence mechanisms.

Muscle Function and Mobility

Vitamin D3 contributes to normal muscle function, which is important for everyone from active athletes to older adults who want to maintain their mobility and strength. Muscle weakness is a known consequence of D3 deficiency, and many people report improved energy and muscle sensation when maintaining adequate D3 levels. This 4000IU formulation provides a powerful dose to support optimal muscle function.

Support for Normal Calcium and Phosphate Balance

Vitamin D3 is essential for regulating calcium and phosphate balance in the body. Without adequate D3, the body cannot absorb calcium effectively from food, even if you consume sufficient amounts. This can lead to the body mobilising calcium from the bones to maintain blood calcium levels, which over time can affect bone integrity. Consistent D3 supply ensures this critical balance is maintained.

Support for Cell Health and Normal Cell Division

Vitamin D3 plays a role in normal cell division and cell differentiation. It acts as a hormone-like substance that regulates gene expression in hundreds of cells throughout the body. By supporting normal cell division, vitamin D3 can help maintain the health of various tissues and organs. This is one reason why vitamin D3 is so essential for long-term health and wellbeing.

Quality & Manufacturing

Grassberg is an established manufacturer of dietary supplements known for its focus on quality and purity. This vitamin D3 formulation is made with gelatin as the capsule material, which is a well-established and well-tolerated material that has been used in the supplement industry for many years.

The product contains soybean as an ingredient, which is important to note for people with soy allergy or sensitivity. Glycerol is used as a humectant to ensure that vitamin D3 remains stable and potent during storage. This combination of ingredients is designed to provide a stable, long-lasting product that retains its potency over time.

Vitamin D3 in this formulation is cholecalciferol, the most biologically active and well-studied form of vitamin D. This is the form the body naturally produces and which many health professionals prefer for supplementation due to its efficacy and stability.

The product is designed for easy daily use with a neutral, flavourless profile that makes it simple to integrate into your daily routine without affecting the taste of food or drink.

Who is the product suitable for?

People with Limited Sun Exposure

If you live at high latitudes, work indoors most of the day, or live in a climate with low sun intensity for many months of the year, this vitamin D3 formulation is particularly relevant for you. Sunlight is the primary source of vitamin D3 for most people, but geographic location, season, and lifestyle can dramatically limit this natural production. A high-dose supplement like this can help fill this gap.

Older Adults and People with Bone Weakness

Vitamin D3 becomes increasingly important with age, as both sun exposure often decreases and the body's ability to produce and metabolise vitamin D declines. Older adults often have an increased need for vitamin D3 to support bone health and maintain muscle strength. This high dose of 4000IU can be particularly valuable for this group.

Active Individuals and Athletes

Vitamin D3 plays a role in muscle function and muscle recovery, making it relevant for active people and athletes. Consistent D3 supply can support optimal muscle function and contribute to faster recovery after exercise. Many athletes use vitamin D3 supplements as part of their training and nutrition strategy.

Vegans and Vegetarians

Vitamin D3 from animal-based sources (such as fish and eggs) is often limited in vegetarian and vegan diets. This Grassberg product uses gelatin as the capsule material, which is worth noting for vegans. For vegetarians who accept gelatin, this can be a practical way to ensure adequate D3 supply.

People with Limited Intake of D3-Rich Foods

Vitamin D3 naturally occurs in a limited number of foods, primarily fatty fish, egg yolk, and fortified milk. If your diet is limited in these foods, or if you follow a restrictive diet for other reasons, a supplement like this can be a practical way to ensure adequate D3 supply.
