    To help restore your body to optimum health and wellness, you need to be taking care of your good bugs.

    Think of your body like an apartment complex. 

    You’re the landlord, and the trillions of tiny bugs are your tenants. 

    Some of those bugs are “good” tenants. They help manage your digestion, boost your energy production, and power your immune system to keep you from getting sick.

    But some of those bugs are “bad” tenants. These include pathogens that can cause illness and harmful yeasts that can wreck your digestion or make you gain weight.

    The lectins, sugars, artificial sweeteners, and other additives found in many modern foods can jeopardize your microbiome and keep you from feeling your best.

    Suggested Use

    Take 2 capsules each day with a glass of water, ideally before a meal to enhance absorption and minimize digestive issues. For best results, maintain a consistent daily schedule. This simple habit supports your overall health when combined with a balanced diet and regular exercise. Always consult your healthcare provider if you are pregnant, nursing, or taking other medications. Store in a cool, dry place and keep out of children's reach. Do not exceed the recommended intake unless directed by a professional.

      We recommend taking it every morning before breakfast and again before dinner. This way, you feel the benefits 24/7.

      How does Bio Complete 3 work?†*

      Bio Complete 3 works to support easier digestion, better weight management, more energy, and less unhealthy cravings by using what I call the "3-Pronged Defense" to gut health:

      Boost your probiotic levels, so you have an abundance of good gut bacteria. Boost your prebiotic levels, so your good gut bacteria have the proper fuel to thrive. Boost your postbiotic levels, so you can enjoy an "ironclad" gut lining (and help combat issues such as low energy and cravings for unhealthy food)

      Can I use Bio Complete 3 for a gut health cleanse?†*

      Some people consider Bio Complete 3 to be a powerful gut cleanse program to help restore their gut and support healthy digestion. Bio Complete 3’s proprietary formula contains quality prebiotics, probiotics, and postbiotics. Together, these essential components help support your digestive health and can help you achieve your gut health goals.

      When can I expect results?†*

      Some users report feeling noticeably smoother digestion, less cravings, along with an increase in energy, vitality, and muscle strength in their first week of use. However, the most results were reported after consistent use over the course of 4 weeks and beyond.

      Is Bio Complete 3 quality-checked?

      Bio Complete 3 contains only the best ingredients. The formula is tested for quality at an independent, 3rd-party laboratory. We recommend consulting with your own health care provider before beginning any new program.
