I found the 250mg size much more manageable to swallow than bulky capsules, and because they are raw and pure, the nutrient absorption feels much more efficient. With 60% vegan protein and a dense profile of B vitamins, iron, and chlorophyll, these tablets act as a legitimate energy booster rather than a temporary caffeine spike. It is a rare find to get a non-GMO, third-party tested supplement that avoids all the usual fillers and binders while providing a massive 1000-count supply.

Beyond skincare, it acts as a potent nutritional powerhouse for your morning smoothie or pasta dishes. Just a heads-up: the flavor is intensely fishy, so don't expect a neutral additive.
