How it works

Ester-C® & Flavonoids is a unique supplement designed to support overall immune health, cellular function, and blood vessel integrity. This advanced formula combines the non-acidic, water-soluble form of vitamin C, known as Ester-C®, with powerful flavonoids like quercetin and rutin. Ester-C® is a premium, calcium ascorbate-based vitamin C that offers superior bioavailability compared to traditional ascorbic acid, making it an ideal choice for those looking to maintain healthy immune function and promote long-term wellness.

Vitamin C plays a crucial role in the body’s defense system, and studies have shown that Ester-C® helps to increase the concentration of vitamin C in white blood cells, ensuring optimal immune support. Unlike standard vitamin C, which may only offer short-term benefits, Ester-C® provides sustained levels of vitamin C that remain elevated for up to 24 hours, enhancing immune protection throughout the day. This makes it an excellent option for those seeking continuous, reliable immune support.

In addition to the vitamin C benefits, the inclusion of flavonoids like quercetin and rutin boosts the product's effectiveness by promoting overall health in complementary ways. Quercetin is a powerful antioxidant that helps maintain healthy mast cell function, regulate leukotriene and prostaglandin metabolism, and support the body’s natural inflammatory response. Meanwhile, rutin, a potent flavonoid, supports blood vessel integrity and cellular health, contributing to the body’s ability to repair and maintain healthy tissues and organs.

Whether you're looking to bolster your immune system, support healthy cell function, or maintain cardiovascular wellness, Ester-C® & Flavonoids provides a comprehensive approach to optimizing your health. This supplement is a great choice for individuals looking for a natural, well-rounded solution to support their overall well-being, with the added benefit of promoting long-lasting vitamin C absorption and bioavailability.

Frequently Asked Questions

Everything you need to know about this product.

What is Pure Encapsulations Ester-C® & Flavonoids?

It is a vegan supplement that combines Ester-C®, a non-acidic, calcium ascorbate-based form of vitamin C, with the flavonoids quercetin and rutin. The formula is designed to support immune health, antioxidant defense, and blood vessel integrity. Each capsule provides 619 mg of vitamin C along with calcium, threonic acid, quercetin, and rutin.

What do the key ingredients do?

Ester-C® offers superior bioavailability and enhanced retention compared to traditional ascorbic acid, helping to maintain elevated vitamin C levels in white blood cells for up to 24 hours. Quercetin is a potent antioxidant that supports healthy mast cell function and the body's natural inflammatory response. Rutin promotes blood vessel integrity and cellular health, working in synergy with vitamin C.

How do I take Ester-C® & Flavonoids?

Take 1 capsule, 1-2 times daily, with or between meals. The 90-capsule bottle provides a 45- to 90-day supply depending on how many capsules you take per day.

Who is this supplement for?

It is a good fit for adults looking to support immune function, cardiovascular wellness, or connective tissue health with a well-absorbed form of vitamin C and complementary flavonoids. It is suitable for those following a vegan or vegetarian diet. If you are pregnant, breastfeeding, taking medication, or considering this for a child, please consult a qualified healthcare practitioner first.

How does this compare to similar vitamin C and immune support products?

Unlike Stellar C™, C+BioFizz®, and Buffered Vitamin C, this formula pairs its enhanced-retention Ester-C® with the flavonoids quercetin and rutin for broader antioxidant and vascular support. If your main goal is zinc-based immune support rather than vitamin C, Pure Encapsulations also offers Zinc Picolinate 30 mg NSF and Zinc Bisglycinate 30 mg, which focus on a different nutrient altogether. Ester-C® & Flavonoids stands out when you want vitamin C and flavonoid synergy in one capsule.
