I am convinced beyond any doubt that this one vitamin mix is what is keeping this 88 year-young man and his wife, robustly healthy and thriving. Yes, we eat well, too, of course. And by eat well, I mean my wife is an undegreed Nutritionist who cooks well balance meals. Do we imbibe our taste for sweets? Yes, but in moderation - AND we walk together about 1.5 miles up and down hills each day the weather allows. So diet, nutrition and vitamin supplementation plus exercise are key to a healthy life if not a longer life. And alcoholic drinks are rarely consumed. We have needed a company like Life Source Vitamins for a long time. I am delighted that they are with us now. iHsay, tom mcdonald
