THE OWNERS AT LIFETIME EACH HAVE OVER 25 YEARS EXPERIENCE IN THE MANUFACTURING AND DISTRIBUTION OF DIETARY FOOD SUPPLEMENTS. YOU WON'T FIND THE LIFETIME BRAND IN DRUG STORES OR CONVENTIONAL FOOD STORES BECAUSE IT IS OUR OPINION THAT PRODUCTS SOLD IN THESE CONVENTIONAL RETAIL OUTLETS ARE SUB-STANDARD TO THE BRANDS SOLD IN NATURAL FOOD STORES. LIFETIME PRODUCTS ARE GUARANTEED FOR QUALITY AND POTENCY. WE TEST EVERYTHING AND CONFORM TO STRICT QUALITY GUIDELINES BOTTOM LINE. PURITY* POTENCY* PRICE. LIFETIME NEVER COMPROMISES ON QUALITY, IT'S THEIR #1 GOAL AS A COMPANY!
