Strained vs. Unstrained: The Key to Higher Protein
The fundamental difference between standard yogurt and high-protein varieties like Greek yogurt and Icelandic skyr lies in the straining process. During production, regular yogurt is fermented and then, for Greek yogurt and skyr, the liquid whey is strained out. This process removes excess water, concentrating the remaining solids and resulting in a much thicker, creamier yogurt with a higher protein content. The more extensive the straining, the thicker and more protein-rich the final product will be.
The Contenders for Most Protein
While Greek yogurt is a well-known source of protein, several brands and styles now pack an even bigger protein punch. The highest protein content is often found in Icelandic skyr, which is strained even more than Greek yogurt, as well as in specially formulated Greek yogurt brands that use ultra-filtered milk or added whey protein to boost their nutritional profile.
Ratio Protein Yogurt
Ratio Protein Yogurt stands out as a leader in the high-protein category, delivering up to 25 grams of protein in a 5.3-ounce serving. This is achieved by using ultra-filtered milk and adding whey protein concentrate.
Oikos Pro
Another top contender, Oikos Pro, offers 20-25 grams of protein per 5.3-ounce serving, depending on the flavor. It is made with ultra-filtered milk and whey protein concentrate, resulting in a thick, creamy texture with less tang than traditional Greek yogurt.
Icelandic Provisions Skyr
Icelandic Provisions Skyr is a naturally high-protein option due to its unique preparation method. Each 5.3-ounce serving contains 17 grams of protein from low-fat, highly strained cultured milk.
Plain Greek Yogurt Brands
Brands like FAGE Total 0% and Siggi's Plain Nonfat Skyr consistently offer a high level of protein, typically in the range of 15-16 grams per serving for unflavored varieties. FAGE is known for its exceptionally thick texture, while Siggi's provides a smooth, less tangy experience.
Boosting Your Yogurt's Protein Content at Home
For those who want to maximize the protein in their yogurt, there are several simple strategies:
- Add Protein Powder: Mixing a scoop of your favorite whey or plant-based protein powder into a serving of plain Greek yogurt can instantly create a high-protein, custom-flavored snack.
- Mix in Seeds: Chia seeds and hemp hearts are excellent additions that provide extra protein, along with healthy fats and fiber.
- Include Nut Butters: A spoonful of peanut or almond butter adds a creamy texture and boosts both protein and healthy fat content.
- Strain It Yourself: To mimic the straining process of Greek yogurt and skyr, you can use a cheesecloth or a fine-mesh sieve to drain the whey from regular yogurt, leaving behind a thicker, more protein-dense product. This is a great way to customize the thickness and protein level to your preference.

Conclusion
While Greek yogurt is a strong source of protein, Icelandic skyr and especially formulated high-protein Greek yogurts from brands like Ratio and Oikos offer the most concentrated protein content. The best yogurt for you will depend on your specific dietary needs and taste preferences, but if maximizing protein is the goal, strained varieties are the clear winner. Plain, unflavored options typically provide the highest protein-to-sugar ratio, and you can easily boost the protein further at home with simple additions like powder, nuts, and seeds. Ultimately, choosing a yogurt you enjoy and will eat consistently is the most important factor for success.

FAQs
Question: Is Greek yogurt or Icelandic skyr better for protein? Answer: While both are excellent sources, some Icelandic skyr and specially formulated protein-enhanced Greek yogurts can have a slightly higher protein concentration per serving. However, both are far more protein-rich than regular yogurt.
Question: Can I increase the protein in my regular yogurt? Answer: Yes, you can significantly boost the protein by adding a scoop of protein powder, mixing in high-protein seeds like chia or hemp hearts, or stirring in some nut butter.
Question: Are high-protein yogurts suitable for people with lactose intolerance? Answer: Some high-protein yogurts, such as Chobani Protein, are specifically made to be lactose-free. Additionally, some individuals with lactose intolerance can tolerate yogurt with live and active cultures, as the probiotics help with digestion.
Question: Do high-protein yogurts have more fat? Answer: Not necessarily. Many of the highest-protein options, including brands like Ratio, Oikos Pro, and FAGE Total 0%, are also low in fat. It's always best to check the specific nutritional label.
Question: How much protein is in regular yogurt versus high-protein yogurt? Answer: A 100-gram serving of regular plain yogurt has about 3.5 grams of protein, whereas the same amount of Greek yogurt can have 9 grams, and skyr up to 10 grams. Specially formulated brands can push this even higher.
Question: Which yogurt is best for building muscle? Answer: For muscle building, a yogurt with the highest possible protein content is ideal. Options like Ratio Protein Yogurt and Oikos Pro, with over 20 grams of protein per serving, are excellent choices, especially as part of a balanced diet with strength training.

Question: Is there a plant-based yogurt with a lot of protein? Answer: Yes, some plant-based options use pea or soy protein to create a high-protein alternative. For example, Kite Hill Greek-Style Plant-Based Yogurt (made with almond milk and soy protein) provides 15 grams of protein per 5.3-ounce serving.
