Doctor's Biome Gut Health (30 Day Supply)
A living probiotic shot masterfully crafted from real fruit and vegetable juices. Infused with probiotics clinically shown to support gut function — bottled alive and kept cold, never freeze-dried into dormancy. Most probiotics are processed into an inactive state and have to come back to life before they can do anything. Every bottle of Doctor's Biome starts with real pressed juice, blended with 15 strains of live cultures and kept cold from our facility to your door — alive the whole way. Just one 2-oz shot in the morning, on an empty stomach — a small, deliberate ritual for people who take their gut seriously.
Probiotics have been studied for their role in:
- Everyday digestion
- Regularity
- Daily energy
- Microbiome support

More Than a Gut Feeling…
There’s a reason the gut is considered the command center for total body health. As the host of trillions of microbes (and up to 5,000 different bacterial species), it plays a key role in battling infections and diseases, improving mood and sleep patterns, strengthening metabolism and immune systems, and so much more.
- There are 10x the number of microbial cells in the human gut than in the whole human body.1
- 70% of the immune system is located in the digestive tract.2
- Research shows gut bacteria can affect cholesterol levels in humans.3
- Recent studies have identified a link between gut health and emotional well-being.4
- Your gut produces a startling 95% of your serotonin, the “happiness hormone.5
