Holland & Barrett offers a diverse range of vitamin D supplements to meet different dietary needs and preferences. The specific ingredients can vary significantly depending on the product's format, whether it is a tablet, gummy, or oral spray. The primary active component is almost always Vitamin D3, known scientifically as cholecalciferol, although the source can differ, especially in vegan products. Understanding the full ingredient list is essential for individuals with allergies, specific dietary restrictions, or those who simply prefer to know exactly what they are consuming.
Core Ingredients Across Formulations
The Active Ingredient: Vitamin D3 (Cholecalciferol)
Across nearly all of its vitamin D supplement range, Holland & Barrett uses cholecalciferol as the active ingredient. This is the same form of vitamin D that the human body naturally produces when exposed to sunlight. A notable exception is their vegan offering, which sources its Vitamin D3 from lichen to avoid animal-derived lanolin.
Bulking and Anti-Caking Agents
These are common excipients used in tablet and capsule formulations to ensure uniform consistency, prevent ingredients from clumping together, and add bulk to make handling easier. Common bulking agents found in Holland & Barrett's vitamin D tablets include Dicalcium Phosphate and Microcrystalline Cellulose. Magnesium Stearate and Silicon Dioxide are frequently added as anti-caking agents to ensure the product flows correctly during manufacturing and doesn't stick together in the packaging.

The Role of Excipients and Additives
Beyond the active vitamin D, the role of excipients and additives is crucial for the product's function, stability, and palatability. Bulking agents like dicalcium phosphate give tablets their mass, while flow agents such as magnesium stearate prevent clumping during production. Gummies rely on gelling agents like pectin and sweeteners for their chewable texture and taste. Sprays utilize emulsifiers and stabilizers to create a consistent, palatable solution. For those needing to avoid specific ingredients, such as animal products, the vegan capsules provide a plant-based alternative using a shell of hydroxypropyl methylcellulose and vitamin D3 from lichen.

A Note on Vitamin D Sources
It is important to be aware of the sourcing of Vitamin D3. Traditionally, D3 (cholecalciferol) is derived from lanolin, a wax from sheep's wool. This makes many standard D3 supplements unsuitable for vegans. As a result, Holland & Barrett provides a vegan-friendly alternative sourced from lichen, a fungus-algae hybrid. In contrast, Vitamin D2 (ergocalciferol), typically derived from yeast, is also available commercially but is considered less effective at raising overall vitamin D levels compared to D3. Holland & Barrett's focus on D3 reflects the general scientific consensus regarding potency.
Conclusion
What are the ingredients in Holland and Barrett vitamin D depends heavily on the specific product chosen. While all formulations share the common goal of delivering Vitamin D3, the inactive ingredients—including bulking agents, anti-caking agents, and flavorings—differ significantly across tablets, gummies, sprays, and vegan capsules. By examining the detailed ingredient list, consumers can select a supplement that not only meets their nutritional needs but also aligns with their dietary restrictions and personal preferences.
