As a calcium supplement, adults take one (1) tablet with any meal, twice daily or as directed by a healthcare provider. Do not exceed recommended dosage. Individual results may vary.Maltodextrin, cellulose. Contains <2% of: Artificial colors (fd&c blue #1, fd&c yellow #5), bha, bht, croscarmellose sodium, gelatin, hydroxypropyl methylcellulose, magnesium stearate, peg, polyvinyl alcohol, starch, stearic acid, sucrose, talc, titanium dioxide, vegetable oil, water.Contains shellfish (oyster).No added yeast or artificial flavors.Labs don’t lie!

I've been using this vitamin for around 5 years now, and I'm happy to say that it has greatly improved my health and life. I was always looking for supplements that would improve my concentration and stamina, but none of them were able to satisfy my needs. After trying Optimum Nutrition's Vitamin B6 Plus, I can finally say that it works! It really helped
