What Is A Probiotic?

Probiotics are live bacteria and yeast that live in your gut microbiome.

Whenever you see the term “gut microbiome,” it’s referring to all of the microorganisms living within your gut. Some of them may be potentially harmful, so-called “bad” bacteria. On the other hand, some are thought to be beneficial, often called “good” or “friendly” bacteria, aka probiotics. [1, 2, 3, 4] 

Researchers believe that having optimal gut health typically means having a good balance between the “bad” bacteria and the “good" bacteria. Ideally, they should co-exist peacefully within the gut.[1, 2, 3, 4] 

Probiotics can be found in some fermented foods like yogurt, kefir, kimchi, sauerkraut, and miso. They are also available as dietary supplements. This may be more convenient for some people to consume, especially if they struggle to eat enough probiotic-rich foods.

Look For:

Try To Avoid:

• Trying to select the cheapest
• Not checking the label
• High serving size
• Extremely high or low price
• Inflated CFU numbers
• Cheap probiotic strains

• Contains high quality probiotic strains
• Includes prebiotics
• 1 capsule serving size
• Fair price
• Great customer service and return policy
• Made in USA
• Third-party laboratory tested

• Uncertain CFU count - CFUs, or colony-forming units, are a method of counting how much live bacteria is in a probiotic product. The amount of CFUs can vary from product to product and can change from 1 to 10 billion (though more is not always better).
• Lack of Third-Party Testing - Always look for ‘third party lab-tested’ verifications that guarantee the product has been independently tested for any heavy metals, bacteria, pesticides, or traces of any other harmful substances. This helps to ensure safety and efficacy of the product.
• Only One Strain - Some products contain a variety of probiotic strains to target different wellness needs.
• Coated Improperly - Some are not enteric-coated (which means that it can travel through the digestive tract to get where it needs to for maximum benefits).*
• Extremely Low or High Price - Do your research before buying an overpriced or suspiciously cheap supplement. Do not cut corners for your gut health.

• Dairy-free

CONS

• Lacks 2 key probiotic strains
• 30-day money-back guarantee
• Unclear if product contains soy

BOTTOM LINE

DS-01® delivers a high CFU count and a solid variety of strains. However, it’s missing two key probiotic strains found in top picks: Lactobacillus acidophilus and  Bifidobacterium bifidum. Seed only offers a 30-day money-back guarantee, which may not be enough time to see if this product is right for your needs. The label clearly states that the product is dairy-free, but leaves it unclear whether the product is soy-free.*
