Bluebonnet Nutrition Vitamin C, D3 & Zinc - Immune Health Support, Soy-Free, Gluten free, Non-GM, Kosher, 100 Vegetable Capsules

What Makes This Supplement Special?

Bluebonnet’s Vitamin C, D3 & Zinc formula uses high-quality, bioavailable ingredients. Vitamin C comes from Non-GM sources, ensuring purity and potency. Vitamin D3 is sourced from lanolin, a natural animal-derived form that mimics the vitamin D your skin produces from sunlight. Zinc is provided as zinc bisglycinate, a chelated form that is gentle on the stomach and highly absorbable. This combination maximises nutrient uptake without unnecessary fillers or additives.

This supplement is also free from soy, gluten, dairy, and artificial colors or flavours. It is Non-GM verified, kosher certified, and packaged in recyclable bottles—reflecting a commitment to both your health and the environment.

How to Choose a High-Quality Immune Support Supplement

When selecting an immune support supplement, look for well-absorbed nutrient forms. Zinc bisglycinate is preferred over zinc oxide or sulphate because of its superior bioavailability. Vitamin D3 (cholecalciferol) is more effective than D2 (ergocalciferol) at raising blood levels. And vitamin C from Non-GM sources like tapioca or corn offers a clean alternative to synthetic ascorbic acid derived from GMO corn.

Also consider certifications: gluten free, Non-GM, and kosher labels indicate third-party verification and higher quality standards. Bluebonnet meets all these criteria. Dosage is another key factor—this product provides 100 servings (one capsule per day), making it easy to maintain consistent intake without overdoing it.

Why Are Vitamin C, D3, and Zinc Important?

Vitamin C, vitamin D3, and zinc are amongst the most researched nutrients for supporting a healthy immune system. Each plays a unique role: vitamin C is a powerful antioxidant that helps protect immune cells from oxidative stress; vitamin D3 modulates immune responses and supports respiratory function; and zinc is essential for the development and function of immune cells. Together, they form a complementary blend that helps maintain daily health and wellbeing*. Bluebonnet Nutrition combines these nutrients in a convenient capsule form, making it easy to support your immune defence year-round.

Frequently Asked Questions

Can I take this with other supplements?

How long does one bottle last?

With 100 capsules and a serving size of one per day, the bottle provides a 100-day supply.

Potential Side Effects and Precautions

Vitamin C, D3, and zinc are generally safe when taken as directed. However, high doses of zinc (above 40 mg daily for adults) can cause nausea, cramping, and interfere with copper absorption. The recommended dietary allowance for zinc is 8–11 mg for most adults. Similarly, excessive vitamin D3 can lead to toxicity over time, so stick to the serving size. Vitamin C is water-soluble and usually well tolerated, but very high doses may cause digestive upset.
