Nupro: “NUPRO is made with fresh quality health food ingredients that are human-grade, not animal-grade.” (that’s what makes this company noteworthy!)
Ingredients: GLUCOSAMINE COMPLEX (500 mg per scoop): is our own special formula that is an easily absorbed natural substance that stimulates the production of proteoglycans which help to maintain the health and resiliency of connective tissues and restores the damaged cells of cartilage tissue. Glucosamine complex helps promote the synovial fluid that lubricates the joints.
METHYLSULFONYLMETHANE (MSM) (300 mg per scoop): is a natural source of bioavailable sulfur, essential for the growth and repair of tendons, cartilage and other connective tissues. MSM is also an anti-inflammatory agent.
ESTER-C* CHELATED MINERAL BLEND (300 mg per scoop): boosts the absorption of the glucosamine complex and MSM and promotes collagen formation.
NUPRO Joint Support also contains Norwegian kelp, flaxseed, nutritional yeast culture (not the same as Brewer’s yeast, but should be used in moderation if yeast sensitive), desiccated liver, bee pollen, garlic, calcium citrate, lecithin and lactobacillus acidophilus.
NUPRO is made with fresh, premium ingredients that are human-grade quality. NUPRO does NOT contain any preservatives, sugar, fillers, corn, wheat, grains, or by-products.
