It contains 15 grams of plant-based protein, 28 vitamins and minerals, and a blend of nootropics including caffeine, L-theanine, and L-tyrosine.

The drink is formulated to support various health aspects, such as immunity and stress management. It includes essential nutrients like vitamin C, vitamin D, zinc, and selenium, which are crucial for immune cell function. Additionally, the presence of L-tyrosine helps improve focus and alertness under stress, contributing to better mood and stress management.
Soylent Complete Energy Chocolate is also designed with healthy aging in mind. It provides adequate protein, fiber, vitamin D, and omega-3 fatty acids, which are important for maintaining physical function, bone health, and muscle strength as one ages. The product is vegan, gluten-free, and low in sugar, making it a versatile option for various dietary needs.
Catalog research summary. Research on an ingredient or product category does not establish this finished product’s effects. Check the claim findings for applicability and source links.
The supplied research concerns soy protein broadly, not Soylent Complete Energy specifically. A 2023 review describes soy protein as generally safe and reports possible health effects, while an RCT meta-analysis found modest improvements in lipoprotein measures with soy protein intake; these findings cannot be attributed directly to this beverage. Another meta-analysis found no significant effects on body weight or body composition in healthy exercising adults, and no supplied study directly evaluates the product’s caffeine/L-theanine combination or its cognitive, immune, mood, or healthy-aging claims.
