Best Protein Supplement for Diabetes I 2025

Diabetes mellitus is a chronic health condition during which our body becomes insulin resistant (in type 2) or totally stops producing insulin (in type 1). Managing diabetes often involves careful attention to diet and exercise. Eat a well-balanced diet with balanced macronutrients (right proportions of carbohydrates, proteins, and healthy fats) and fiber (for blood sugar control). Limiting carbohydrates while having a good portion of good fats added to your diet has been shown to treat diabetes (when detected and implemented in the early stages).

Discussing protein specifically, this macronutrient is essential for building and repairing tissues, creating enzymes and hormones, and supporting a healthy immune system. While consuming protein in the form of real food should always be a priority, there are people out there who find it easier to use protein supplements instead. Let’s check out what to see before selecting the best protein supplement for diabetes and general healthcare routine.

Protein Sources: Food First!

Before diving into supplements, remember that whole food sources are the best way to get your protein. Here are some easily accessible options:

• Lean Meats: Chicken breast (31g per 100g), turkey (29g per 100g), and lean beef (varies based on the cut; a fresh cooked generally contains approx. 26 grams of protein).
• Fish: Salmon (20g per 100g), tuna (28 – 29g per 100g), cod (18g per 100g), and other seafood.
• Eggs: A versatile and complete protein source. A 50g egg contains 6 grams of protein.
• Dairy: Greek yogurt (10g per 100g), cottage cheese (11g per 100g), and full fat milk contains about 3.2 to 3.4 grams of protein per 100g.
• Legumes: Beans such as field pea (26g per 100g), soybeans (13g per 100g), mung beans (23g per 100g), cowpea and common pea (24g per 100g), and chickpea (21g per 100g).
• Nuts and Seeds: Almonds (21g per 100g), walnuts (15g per 100g), chia seeds (17g per 100g), and flaxseeds (18g per 100g).

Remember: Keep monitoring your blood sugar to avoid any glucose spikes. CGM sensors like Libre 2 Plus sensor and Dexcom G7 sensor are helping people monitor their glucose 24/7 without the hassle of repeated fingerpricks.

Protein Supplements: When You Need a Boost

Sometimes, getting enough protein from food alone can be challenging. That’s where protein supplements come in. They’re available in various forms:

• Powders: The most common form, easily mixed with water, milk, or smoothies. Powdered form is considered easier as the servings can be easily adjusted.
• Bars: Convenient on-the-go options, but check the labels carefully for sugar and carb content.
• Capsules: Less common but available for those who prefer a pill form.

A study shared by PubMed where a group of athletes were administered protein bars in 2 successive phases with 7-day long washout periods between phases has shown that the consumption of created high protein bars physiological adaption after training.

According to the study, “the results showed that bar consumption significantly decreased serum aspartate transaminase (AST) and lactate dehydrogenase (LDH) and increased total and direct bilirubin levels, suggesting lower exercise-induced muscle damage and increased antioxidative response, respectively.”

Whey Protein for Diabetics: What to Look For

Whey protein, derived from milk, is a popular choice due to its fast absorption and complete amino acid profile. When choosing a whey protein supplement for diabetes, consider these factors:

• Low Sugar and Carbohydrates: Look for products with minimal added sugars and carbohydrates.
• Third-Party Testing: Seek brands that undergo third-party testing for purity and quality. Reputable organizations like NSF International and Informed-Choice provide certifications that validate product quality.
• Protein Percentage: Aim for a product with a high protein percentage (ideally 80% or more).
• Minimal Additives: Avoid artificial sweeteners, flavors, and colors. Look for natural or stevia-sweetened options.
• Accreditations: In the USA, look for GMP (Good Manufacturing Practices) certifications.

Natural Whey Protein?

You can get whey protein naturally from dairy products like milk and yogurt. However, supplements provide a more concentrated and isolated form, allowing for precise protein intake without the added sugars and fats found in some dairy products.
Plant-Based Protein for Diabetics: A Vegan-Friendly Option

Plant-based protein supplements are excellent for those with diabetes who follow a vegetarian or vegan diet, or have dairy sensitivities. Look for:

• Complete Protein Sources: Choose blends that combine different plant proteins (e.g., pea, rice, soy) to ensure you get all essential amino acids.
• Low Sugar and Carbohydrates: Similar to whey, prioritize products with minimal added sugars and carbs.
• Third-Party Testing and Accreditations: Look for the same certifications as with whey protein (NSF, Informed-Choice, GMP).
• Fiber Content: Some plant-based proteins contain fiber, which can help regulate blood sugar levels.
• Minimal Additives: Just like with whey, avoid artificial additives.

Natural Plant Protein?

You can obtain plant-based protein directly from foods like:

• Soybeans: Tofu, tempeh, and edamame are excellent sources.
• Lentils and Beans: Versatile and rich in protein and fiber.
• Quinoa: A complete protein grain.
• Nuts and Seeds: Almonds, chia seeds, and pumpkin seeds.
• Green peas: A good source of protein.

However, supplements offer a concentrated and convenient way to increase protein intake without consuming large quantities of these foods.

Sugar-Free Protein Shakes: A Closer Look

“Sugar-free” doesn’t always mean “fat-free.” Some sugar-free protein shakes may contain high levels of fat, which can be problematic for people with diabetes. When choosing a protein shake, look for:

• Low Sugar and Carbohydrates: Prioritize shakes with minimal added sugars and carbs.
• Healthy Fats: Choose shakes with good fats, such as those from nuts, seeds, or avocado.
• Fiber Content: Fiber can help regulate blood sugar levels.
• Protein Content: Ensure the shake provides a sufficient amount of protein.
• Taste and Texture: Consider your personal preferences. Many brands offer a variety of flavors, such as chocolate, vanilla, and fruit blends.
• Look for products that are low in net carbs. Net carbs are the total carbohydrates minus the fiber.

Finding the Right Fit

It’s crucial to consult with your doctor or a registered dietitian before starting any new protein supplement, especially if you have diabetes. They can help you determine the appropriate amount of protein for your individual needs and recommend suitable products.

Remember:

• Whole foods should be your primary source of protein.
• Protein supplements can be a helpful addition to a balanced diet.
• Always read labels carefully and choose products with minimal added sugars and carbohydrates.
• Prioritize third-party tested products.
• Taste is subjective, so try a few different brands to find what you like.

By making informed choices, you can find the perfect protein supplement to support your diabetes management and overall health.

Conclusion:

Consuming protein from foods should be preferred; however, if you experience difficulty in protein consumption from foods, consider talking to your doctors about taking protein supplements. When selecting the best protein supplement for diabetes, never forget to check the sugar/carbohydrate content. Remember, glucose monitoring is the key to keeping your diabetes in control, and continuous glucose monitoring without finger pricks is possible with the help of continuous glucose monitors (CGMs).
