Vitamin D Supplements
Vitamin D is one of the most critical nutrients for immune function — and one of the most commonly deficient, particularly in the UK where sunlight exposure is limited for much of the year. The NHS recommends that everyone in the UK considers taking a vitamin D supplement, especially during autumn and winter.
- Feel Supreme Vitamin D3 5000IU Tablets (60 Tablets) — a high-strength vitamin D3 supplement at 5000IU per tablet — ideal for those with confirmed deficiency or those seeking robust immune and bone health support
- Veganates Vitamin D3 2500IU & K2 MK7 with Elderberry Extract — a comprehensive vitamin D3 and K2 supplement combining D3 for immune and bone support with K2 MK7 to direct calcium to the bones rather than arteries, plus elderberry extract for additional immune support
- Chewwies Vitamin D3 Sugar-Free Vegan Gummies (30 Gummies) — a vegan, sugar-free vitamin D gummy using pectin rather than gelatine — a delicious and convenient daily vitamin D supplement suitable for vegans

Key Nutrients for Immune Support
- Vitamin D3 — regulates immune cell function and is essential for the body's first-line immune defences. Deficiency is associated with increased susceptibility to infection and autoimmune conditions
- Vitamin K2 MK7 — works synergistically with vitamin D3 to support immune function and direct calcium to bones rather than soft tissues
- Vitamin C — a powerful antioxidant that supports the production and function of white blood cells, reduces the duration of colds and supports collagen synthesis for skin barrier integrity
- Curcumin — the active compound in turmeric, curcumin has potent anti-inflammatory and antioxidant properties that support immune modulation and reduce chronic inflammation
- Beta-glucans — found in medicinal mushrooms like agaricus blazei, beta-glucans are among the most researched natural immune-modulating compounds
- Iodine — essential for thyroid function, which regulates immune response, metabolism and energy production

Why is vitamin D so important for immunity?
Vitamin D plays a critical role in regulating the immune system — it activates immune cells, supports the body's first-line defences against infection and helps modulate the inflammatory response. Deficiency is extremely common in the UK due to limited sunlight, and is associated with increased susceptibility to respiratory infections and other immune-related conditions. The NHS recommends that everyone in the UK considers taking a vitamin D supplement, particularly during autumn and winter.
Should I take vitamin D3 with K2?
Yes — vitamin D3 and K2 work synergistically. Vitamin D3 increases calcium absorption, while vitamin K2 (particularly MK7) directs that calcium to the bones and teeth rather than soft tissues and arteries. Taking D3 and K2 together is considered best practice for bone health, cardiovascular health and immune support. The Veganates Vitamin D3 2500IU & K2 MK7 supplement combines both in a single tablet.
