Thorne Supplements at ProActive Healthcare


Bio-Gest ensures comprehensive digestive aid with the inclusion of hydrochloric acid, pepsin, pancreatin and ox bile. These elements are integral for individuals who require enhanced protein and carbohydrate digestion as well as fat emulsification and absorption. Unlike its digestive aid counterparts, Bio-Gest stands out for featuring undiluted pepsin and pancreatin that are free from lactose.


The most common amino acid circulating in the blood is L-glutamine. This powerhouse nutrient has a great affinity for the gastrointestinal tract and can be found there in high concentrations, making it an indispensable part of good health.

Studies indicate that L-glutamine supplementation is advantageous for digestive wellbeing, wound care and immune support. Additionally, it aids in restoring plasma glutamine levels that are diminished during times of prolonged physical stress such as extended exercise sessions.

Manganese Bisglycinate

Manganese Bisglycinate is a fully reacted mineral chelate that exhibits optimal absorbability. It is a necessary element for proper functioning of the mitochondria, bones, liver, pancreas and kidneys and it is instrumental in balanced carbohydrate metabolism, reproductive health and development of skeletal structures as well as cartilage.

Manganese supplementation not only provides joint and muscle support, but also helps to maintain the health of ligaments and tendons. This makes manganese a necessary nutrient for supporting overall connective tissue wellbeing.

In addition to aiding in enzyme production and the formation of collagen, manganese also serves as a vital cofactor for superoxide dismutase (SOD), an antioxidant that defends cellular membranes from oxidative harm.


Vitamin B12 supplements are often formulated with cyanocobalamin, which must initially be "detoxified" and converted by the liver into methylcobalamin – an active form of B12 that plays a crucial role in keeping your heart healthy, aiding sleep quality, forming blood cells, and supporting nerve health.

Thorne's Methylcobalamin is the perfect solution for those seeking a convenient source of Vitamin B12 in its most biologically active form, as it has already been pre-processed and designed for easy absorption into your body.


Niacinamide, or nicotinamide as it is also known, is a non-flushing form of vitamin B3 that has multiple beneficial effects on the body. Not only does niacinamide aid in restful sleep and healthy joints and skin, but its antioxidant properties help to inhibit free radical formation.

Additionally, studies have suggested that it can even promote beta cell regeneration in the pancreas! Studies have revealed that Niacinamide can activate neurotransmitter receptors in the brain without actually bonding to those receptors. This induces a soothing, sedative-like sensation throughout your body.

Abundant levels of niacinamide have been shown to protect joint cartilage cells, as well as aid with a variety of skin conditions. Notably, this vitamin is not sourced from yeast.

Vitamin C With Flavonoids

You might only think to take Vitamin C during the winter months, yet it is essential for your overall health all year round! Not only does it give your immune system a boost and aid in collagen production, but its detoxifying properties are also widely known. Relying on this powerful vitamin can help you stay healthy and energetic no matter what season of the year it may be.

As our bodies cannot generate vitamin C, it is imperative to acquire this vital nutrient through a nutritious diet or supplementation and Thorne's Vitamin C with Flavonoids is the perfect combination of ascorbic acid and naturally-occurring citrus flavonoids. Not only does it provide more antioxidant capacity than plain Vitamin C alone, but its superior free radical scavenging abilities can help protect your body from oxidative damage.

Vitamin D Liquid

Vitamin D is a fundamental component throughout our lives, starting from when we're just developing in the womb. It safeguards numerous vital mechanisms in the body such as strong muscles and bones, cardiovascular health, and an effective immune system.

Due to seasonal, geographic and lifestyle changes, many of us fail to get sufficient direct sunlight exposure - a key source of vital Vitamin D. This is where supplementation plays an important role in providing quality amounts of vitamin D for improved health benefits.

Thorne Vitamin D Liquid is ideal for adults and children alike, allowing simple supplementation with daily food or beverage. The liquid vitamin contains a base of medium chain triglyceride oil without any soy oil or sesame oil added, while being preserved with natural vitamin E in the form of mixed tocopherols.
