What Yogurt Has the Highest Amount of Probiotics?

3 min read

According to the FDA, a product with a "live and active cultures" seal must have had at least 100 million live bacteria per gram at the time of manufacture. This article reveals what yogurt has the highest amount of probiotics and how to identify the most potent options for your gut health.

Quick Summary

This guide examines different fermented products like kefir and yogurt, and explains what defines a probiotic powerhouse. It offers crucial tips on reading labels, selecting brands, and identifying live cultures to boost your gut health effectively.

Key Points

Kefir is Supreme: The fermented drink kefir generally contains the highest count and most diverse range of probiotic strains compared to any traditional yogurt.
Check for 'Live & Active Cultures': Always read labels for this phrase to ensure the product contains viable probiotics that have not been killed by heat-treatment.
Plain is Best: Opt for plain, unsweetened yogurt to avoid added sugars that can feed harmful gut bacteria and undermine the benefits of probiotics.
Greek & Skyr are Potent: Strained yogurts like Greek and Icelandic skyr offer high protein and often higher concentrations of probiotics than regular yogurt.
Not All Strains are Equal: Different probiotic strains offer specific benefits, so consider products with a variety of strains for broader health support.
Homemade Offers Control: Making your own long-fermented yogurt at home with specialized starter cultures can produce exceptionally high probiotic counts.

Understanding Probiotics in Yogurt

Not all yogurt is created equal when it comes to probiotic content. Yogurt starts with Lactobacillus bulgaricus and Streptococcus thermophilus, but not all finished products have enough live cultures, especially if heat-treated after fermentation. Look for "live and active cultures" or the National Yogurt Association's seal for assurance of viable probiotics.

The Probiotic Powerhouse: Kefir

Kefir, a fermented milk drink, often surpasses yogurt in probiotic content and diversity. It can contain significantly more probiotics than some yogurts, with certain brands reaching over 45 billion cultures and offering a wider range of up to 61 different strains due to its fermentation with kefir grains. Kefir includes a mix of bacterial and yeast strains like Lactobacillus, Lactococcus, Streptococcus, and Leuconostoc, potentially providing broader health benefits.

High-Probiotic Yogurt Varieties

For those who prefer yogurt, several types stand out for their probiotic levels.

Greek and Icelandic Yogurt (Skyr)

Greek yogurt and skyr are strained, resulting in a thicker texture and higher protein. Straining doesn't necessarily remove beneficial bacteria; some studies suggest these yogurts can have higher probiotic concentrations. Skyr's unique culture and higher milk content make it particularly thick and protein-rich. Brands like Fage and Icelandic Provisions are known for their probiotic content.

Activia

Activia is known for its specific probiotic strain, Bifidobacterium animalis lactis DN-173 010, and is marketed for digestive regularity, containing billions of live cultures per serving.

Homemade Yogurt

Making yogurt at home allows control over strains and fermentation time. Long-fermented homemade varieties, such as L. reuteri superfood yogurt, can yield extremely high bacterial counts. This can take up to 36 hours and requires specific starter cultures.

Probiotic Yogurt Comparison Table


Feature	Kefir	Greek Yogurt	Plain Regular Yogurt	Homemade Yogurt (Long-fermented)
Probiotic Count	Very High	High	Varies (check label)	Potentially Highest
Strain Variety	Very High (up to 61)	Moderate to High	Varies (check label)	High (dependent on starter)
Texture	Drinkable, tart	Thick, creamy	Thinner	Varies (dependent on straining)
Protein	High	Very High	Moderate	High
Added Sugar	Varies; plain has none	Varies; plain has none	Varies; plain has none	None (user controlled)

What to Look for When Buying Probiotic Yogurt

Choosing the right yogurt involves checking labels for "live and active cultures", opting for plain and unsweetened varieties to avoid sugars that can harm gut bacteria, and considering higher protein options like Greek or skyr. Look for a variety of bacterial strains and avoid products heat-treated after fermentation.

Leading Probiotic Strains and Their Benefits

Specific strains offer distinct benefits. Lactobacillus acidophilus helps with lactose digestion. Bifidobacterium lactis (B. animalis lactis in Activia) is linked to improved digestion and immunity. Lactobacillus casei may help with antibiotic-associated diarrhea, and Lactobacillus rhamnosus GG can strengthen the intestinal barrier.

Conclusion: Making Your Choice

For the highest amount of probiotics, kefir is generally the top choice due to its quantity and diversity. Greek or Icelandic skyr yogurts are excellent spoonable alternatives with high protein and probiotics. Being a mindful consumer means checking labels for "live and active cultures," choosing plain varieties, and considering products with diverse strains.

For more detailed information on probiotic strains, you can consult resources like the National Institutes of Health.

Frequently Asked Questions

Greek yogurt often retains a higher concentration of probiotics than regular yogurt due to its straining process. However, probiotic content can vary significantly by brand, so always check the 'live and active cultures' label.

Yes, kefir is generally considered superior to most yogurts for probiotics. It typically contains a much higher number of total probiotics and a more diverse range of strains, including both bacteria and beneficial yeasts.

Look for the phrase 'live and active cultures' on the packaging. You can also check for the National Yogurt Association's 'Live & Active Cultures' seal, which guarantees a certain level of viable cultures at the time of manufacture.

Key strains often listed on probiotic yogurt labels include Lactobacillus acidophilus, Bifidobacterium lactis, and Lactobacillus casei. Seeking a variety of these strains can offer a wider range of potential health benefits.

Plain, unsweetened yogurts are typically a healthier choice. Many flavored varieties contain high amounts of added sugar, which can counteract the beneficial effects of the probiotics. It's best to add your own fruit or natural sweetener to a plain base.

No. Any yogurt that is heat-treated after the fermentation process will have its probiotics killed off. Look for yogurt that is clearly labeled with 'live and active cultures' to ensure the microbes are still viable.

Yogurt and other fermented foods provide a natural, food-based source of probiotics, along with other nutrients like protein and calcium. Supplements can provide a higher, more controlled dose of specific strains. The best option depends on your dietary preferences and health goals.
