Connective tissue support with BioCell Collagen
Benefits and Features
- Promotes joint comfort and mobility†
- Promotes cartilage health and stimulation†
- Promotes synovial fluid health†
- Promotes post-workout recovery†
- Boosts collagen type II and hyaluronic acid†
Protects and supports healthy skin, cartilage, and connective tissue with a patented combination of hydrolyzed collagen type II, chondroitin sulfate, and hyaluronic acid.†
Detail Overview
BioCell Collagen™ is a concentrated source of bioavailable, hydrolyzed collagen type II, chondroitin sulfate, and hyaluronic acid. A patented process produces a low molecular weight mixture of components that are easily absorbed and readily available for use in the body to protect connective tissues, promote cartilage synthesis, support repair, and improve the overall appearance of the skin.† Collagen type II, the most abundant protein found in joint cartilage, helps support new cartilage synthesis and quenches free radicals in joint tissue.† Hyaluronic acid is an important nourishing agent that helps to retain the natural moisture content of skin tissue and joint fluids.† Chondroitin sulfate supports the synthesis of cartilage tissue and inhibits cartilage-degrading enzymes.† OptiMSM®, a sulfur and methyl donor, supports joint structure and comfort. Vitamin C is required for hydroxylation, a biochemical process required for cartilage synthesis.† Two capsules twice daily supplies approximately 1 g of collagen type II protein, 400 mg of chondroitin sulfate, 200 mg of hyaluronic acid, and 1 g of OptiMSM®.

High-Potency Retinyl Form
Benefits and Features
- 7,500 mcg
- 25,000 IU
- Facilitating the support of visual and immune systems effectively
Detail Overview
Vitamin A, provided in the forms of retinyl palmitate and fish liver oil, is an indispensable nutrient with wide-ranging benefits for bodily health. Retinyl palmitate is a chemically stabilized ester form of retinol, which is an active form of vitamin A. This form is particularly beneficial as it is more stable and less susceptible to oxidation, making it a preferred choice in dietary supplements for ensuring consistent and reliable dosage. It is easily absorbed and utilized by the body, facilitating the support of visual and immune systems effectively.
Vitamin A's role in maintaining vision is paramount; it is crucial for the proper functioning of the retina, particularly in converting light into neural signals which enable vision in low-light conditions. This function is mediated by retinal, a specific form of vitamin A that interacts with protein opsin to form rhodopsin, a molecule integral to the vision process in dim lighting. Beyond its vision-enhancing capabilities, vitamin A is vital for the growth and development of cells lining the eyes. By supplementing with retinyl palmitate or fish liver oil, individuals can support their ocular health robustly, preserving and enhancing vision functionality.
The immune-enhancing properties of vitamin A are equally critical. It supports immune health by maintaining mucosal surfaces by helping in the production and function of white blood cells, which play a crucial role in capturing and clearing pathogens from the bloodstream and lymphatic system. This includes the lining of the airways and digestive tract, which are the body's first line of defense against disease-causing organisms. Vitamin A also influences the function of immune cells, including T-cells, B-cells, and cytokines, which coordinate the body's response to pathogens and inflammation. Moreover, it is integral to the skin's defense system, promoting the turnover of skin cells and maintaining the integrity of skin that serves as a barrier against environmental threats. By fostering these barriers and cellular functions, vitamin A plays an essential role in defending the body against infections and maintaining overall immune resilience.

100 mg Ubiquinol
Benefits and Features
CoQ10 in its potent antioxidant form that is more difficult for the body to generate as we age and for individuals with certain health conditions.
Detail Overview
Two beneficial forms of CoQ10, ubiquinone, and ubiquinol, are continually recycled in the body. Ubiquinol acts as a powerful antioxidant in mitochondria and lipid membranes.† Sufficient amounts of both forms are needed for efficient ATP production. Normally, ubiquinone is efficiently reduced to ubiquinol during absorption or shortly after entering the bloodstream. However, this ability declines with age and may be compromised in certain individuals. As ubiquinol can be directly utilized by the body, CoQH™ is a good alternative for those who may have difficulty converting ubiquinone to ubiquinol. Pure ubiquinol is solubilized in d-limonene oil and stabilized with natural emulsifying agents.
