NATURESZEST® Vitamin D3 4000IU – 365 Vegetarian Tablets (1-Year Supply), Supports Immunity, Bones & Muscles

Boost your daily health with NATURESZEST® Vitamin D3 4000IU, a high-strength supplement designed to support your immune system, bone strength, and muscle function. Each tablet delivers 100µg (4000IU) of premium Vitamin D3, ensuring optimal levels year-round, especially during darker months when sunlight exposure is limited.

Why Choose Our Vitamin D3?

✔ Immune & Bone Support – Vitamin D3 helps regulate calcium and phosphate, essential for maintaining healthy bones, teeth, and muscle function. It also plays a key role in supporting your immune system.

✔ High Potency & Long-Lasting – With 365 easy-to-swallow vegetarian tablets, this 1-year supply ensures consistent daily intake without frequent reordering.

✔ Premium Quality & Safety – Made in the UK under strict GMP standards, our formula contains no artificial colors or preservatives and is suitable for vegetarians.

✔ Trusted Recommendation – Public Health England advises considering a Vitamin D supplement, particularly in winter, to maintain optimal levels.

Who Needs Vitamin D3?

Those with limited sun exposure, vegetarians, or anyone seeking extra immune and bone support will benefit from this supplement. Since Vitamin D is found in few foods (like oily fish and eggs), supplementation helps bridge nutritional gaps.
