Did you know that 60-80% of your immune system resides in your digestive tract?
The microbiome, a community of bacteria in your gut, plays a crucial role in developing your body's immune response to foreign pathogens and infections.
That's why your gut health is so important!
One proactive method to boost gut health is to increase the presence of probiotics in your digestive system.
Probiotics are live bacteria that aid in restoring the balance of "good" bacteria in your gut.
You can find them in fermented foods such as kimchi, yogurt, or sauerkraut.
However, incorporating fermented foods into your daily routine can be challenging.
This is where probiotic supplements come in handy
Allow us to introduce Korea's #1 Best Selling Probiotic - LACTOFIT GOLD!
Each Lactofit packet delivers over 2 billion CFU of Lactobacillus, with added zinc (2.55 mg / 30% DV) to support immune health.
The LACTOFIT Gold formula has been upgraded (LACTO 5X™ formula) to include Prebiotics & Postbiotics.
Prebiotics provide the necessary food and energy for probiotics to thrive in your gut, while postbiotics are the byproducts that further enhance your gut health.
The new upgraded formula consists of 5 key probiotic strains that specifically target different areas of your digestive tract. This comprehensive approach aids in restoring a healthy gut microbiome.
LactoFit is made with the highest-quality, science-backed probiotics, namely Lactobacillus acidophilus DDS®.
If you experience digestion issues such as indigestion, diarrhea, irritable bowel syndrome, constipation, or simply wish to proactively care for your immune system, consider supplementing your diet with LactoFit.
One containers contains 50 packets.
Simply take 1 packet per day, straight, without water!
