The chances of hitting a trifecta - that's betting correctly on which horse will finish first (win), second (place) and third (show) - are slim, but the payoff is huge. A $2 bet on the trifecta at the Kentucky Derby last year paid $6,925.60. Not bad. But putting your $2 toward three winning probiotics - Lactobacillus acidophilus, Lactobacillus rhamnosus, and Lactobacillus reuteri - well, that delivers a payoff every day.

Making sure you have the right balance of these good-for-you bacteria in your intestines (that's where they live!) can help you lose weight, lower cholesterol and reduce your risk for Type 2 diabetes and its complications while keeping your cardiovascular system healthy. They thrive in foods you love (really!), and you can take them as supplements.

Lactobacillus acidophilus is in probiotic yogurt and fermented soy products like miso and tempeh. Most often thought of as a digestive aid, it's also good for treating vaginal yeast infections.

Lactobacillus rhamnosus acts as anti-inflammatory in your gut and helps fight obesity and insulin resistance. You can enjoy it in probiotic yogurt, fermented soy and fermented milks. Remember: Dairy products help probiotics survive through stomach acid, but make sure you choose non-fat, no-added-sugar dairy.

Lactobacillus reuteri reduces lousy LDL cholesterol and your risk of coronary heart disease. You can get it in supplements, and it's in breast milk (just FYI) and even chewing gum designed to control dental plaque and gingivitis.

We're betting this lacto-trifecta will show you good bacteria in the right place and that's a big health win!
