Everything You Know About Probiotics Is Wrong
We tested the best-selling probiotics and found most contain less than 10% of the live bacteria claimed.
So we created the Smart Probiotic with acid-resistant strains and delayed-release technology proven to deliver 33.7bn CFUs (170% of our minimum claim) of live bacteria to your colon.
The Smart Probiotic- the best in gut health + mental & immune health.
The brain sends messages all over the body, and science has discovered the gut talks back.
FACT: 95% of your happy hormone, serotonin, is produced in the gut.
That’s why Heights developed the first probiotic formulated to target the gut-brain connection, using 7 unique probiotic strains backed by clinical studies shown to support your health.
200x more good bacteria, 380+ clinical studies, and delayed-release technology proven to help bacteria reach the gut alive.

Most probiotics don’t work—the bacteria die before they reach the gut.
