Sheila V.

"I've lost 20 pounds plus 4 inches in both my waist and hips. I have more energy, feel so much better and my sugar cravings and snacking are gone!"*


"Thank you VitaMedica for helping me lose 17 pounds and 9 inches in just 2 months. Your probiotic supplements and Lean Meal Replacement were the perfect combination to help reduce my appetite and keep me focused each day. I began your program just before an extremely stressful period for my family. Knowing that I had my meal replacement each evening helped to simplify my life and give me the energy I needed. I love the shaker and the vanilla shake is so good. I look forward to trying the chocolate soon. Thanks so much! You are making a difference!"*


"I can't tell you how much I love my Dutch chocolate LeanMeal shakes. I know there are limitless options to make various smoothies but honestly the best thing about it is that I can be on the fly - mix it with 10-12 oz. of water (makes it last longer and still tastes very chocolaty!) and off I go. It mixes better than any other powder I have tried and it doesn’t give me the "too much fiber, run to the bathroom" that I have gotten with other shake mixes. I recently traveled abroad and was thrilled to have the packets in my purse an emergency starvation attack! Congratulations on creating what in my opinion is the best healthy shake out there!"*


"LeanBiotics has really helped me to lean out, I feel fantastic! Really enjoy having my protein shakes in the morning, their so delicious!!!"*

The importance of the microbiome for a healthy weight

LeanBiotics is based on cutting-edge scientific discoveries which demonstrate the role beneficial bacteria play in weight management.

As the first patent-pending weight management program based entirely on modifying your gut microbiome, LeanBiotics is uniquely designed to address the root causes of your weight loss woes.*

Especially if you’ve tried and failed to lose weight with other programs in the past, see the science behind why modifying your gut microbiome with LeanBiotics can make all the difference:

Obese individuals have a greater proportion of “obese” gut bacteria and lower amount of “lean” gut bacteria than lean individuals .

Learn More

“Obese” bacteria extract more energy (calories) from the foods we eat, and this influences whether we are more likely to be lean or obese.

Learn More

People with large and diverse bacterial populations in their digestive tract tend to be less prone to obesity than people with low microbial diversity .

Learn More

Early exposure to antibiotics leads to obesity later in life.

Learn More

Gut bacteria make us crave the nutrients they need to flourish .

Using artificial sweeteners alters gut bacteria .
