Nature's Secret® 15-Day Weight Loss Cleanse & Flush®

Stimulates Digestion and Enhances Elimination*
Flatter Abdomen and Less Bloating*

Slow digestion is a common concern, especially with today’s lifestyle of diets that are often void of fresh raw vegetables and high-fiber foods. Poor assimilation of food can lead to bloating and a feeling of low energy. Having a well-functioning digestive system promotes energy and vitality, leading to better overall health.

Nature’s Secret 15-Day Weight Loss Cleanse & Flush helps stimulate healthy digestion and supports cleansing of the digestive tract.* The botanicals and fiber in this product may help reduce bloating, clean out the digestive system and help to flatten the appearance of the abdomen.* Once your digestive system is cleansed, absorption of nutrients and energy from food is enhanced, making you feel lighter, more energized and healthier.*

I was feeling bloated and wanted to lose a few pound if possible. I walked 30 to 60 minutes on the treadmill several days a week. I tried to eat healthier and drink more water everyday. I lost 7 pounds! I'm not bloated, I feel a lot better and lighter...

I'm ordering another bottle hopefully I can add more exercise and lose a few more pounds!

How often can one use this product? (i.e. Use for 15 days every month or every 3 months????) What is safe?
A shopper on Apr 2, 2013
BEST ANSWER: You can use this product twice daily for 15 days. It's not recommended you continue or do more than that, as it is a 15-day-weight-loss formula. They say to wait 30 or more days after you end this if you want to begin taking them again, but they advise not to use it long term. Not using this item long term would be safest.
