Review on Sunwarrior Classic Plus Organic Vegan Protein Powder - BCAAs, 💪 Pea Protein, Dairy-Free, Gluten-Free, Soy-Free, Non-GMO, Keto-Friendly - Vanilla Flavor (30 Servings) by Melissa Cunningham

I tried to write this as a question but I couldn't find a way to ask the question. I received this product a few weeks ago on recommendation. It was packaged well and I really like the nutritional profile. However, small, oval, hard black granules of approximately 2mm x 3mm are present in the powder mixture. Is this a normal part of the mix, like chia seeds (although they are larger than the chia seeds I buy) or is it a contamination? Should it be an absolutely homogeneous mixture? The attached photo shows the powder on a paper towel. The nature of the kitchen paper indicates the proportion of fine grain.
