Procosa: glucosamine, curcumin, and the full label

Joy Health transcribed every row below and checked it against the U.S. label USANA publishes.^[1] Amounts, units, and % Daily Values are exactly as printed. Formulas change, so compare the label on your own package.

Directions on the label: Adults take three (3) tablets daily, preferably with food.

Other ingredients: Microcrystalline Cellulose, Croscarmellose Sodium, Modified Cellulose, Ascorbyl Palmitate, Organic Maltodextrin, Calcium Silicate, Organic Sunflower Lecithin, Organic Palm Olein, Organic Guar Gum.

Glucosamine and the curcumin complex sit inside what the label calls the InCelligence Joint-Support Complex, and neither has a Daily Value. The label names the curcumin ingredient “Meriva Bioavailable Curcumin Complex.”^[1]

Manganese is the Procosa nutrient closest to an upper limit, at 5 mg a day against 11 mg. CellSentials and HealthPak each add 2 mg a day, which brings a combination to 7 mg before food. NIH notes that people with chronic liver disease are more susceptible to excess manganese.^[5]

Daily amounts multiply the label's per-serving amounts by the servings its directions call for. Food, drinks, fortified foods, and other supplements add to these totals. A Tolerable Upper Intake Level (UL) is the highest daily intake likely to pose no risk of adverse effects for almost all healthy people in an age group. It is not a recommended intake.^[7]

Yes. Procosa is certified to NSF/ANSI 173: NSF's official listing for USANA's Salt Lake City facility names PROCOSA™ under NSF/ANSI 173, with a recommended daily serving of 3 tablets.^[2]

Joy Health interpretation: the listing is about whether the tablets match their label. Whether glucosamine or curcumin helps joints is a separate evidence question; the supplement evidence guide explains how to check a claim like that.

• Warfarin. NIH notes that glucosamine and chondroitin have been associated with an increased risk of bleeding in people taking warfarin.^[3]
• Blood sugar. Glucosamine may raise blood glucose in some people, NIH reports.^[3]
• Liver. NIH reports liver damage in some people who took highly bioavailable curcumin formulations, and people with chronic liver disease are more susceptible to excess manganese.^[4][5]
• Pregnancy and breastfeeding. NIH says turmeric supplements during pregnancy may be unsafe, and that little is known about glucosamine during pregnancy or breastfeeding.^[3][4]

FDA does not approve dietary supplements before they are sold, and it advises talking with a doctor, pharmacist, or other health professional before using one, because some supplements interact with medicines or other supplements.^[6]
