User cfe3b4 has asked for advice regarding protein shakes for their teenage son, who is working out daily and losing weight due to insufficient nutrient intake. They are seeking recommendations for a protein shake to provide their son with enough energy and nutrition. User 6a02b7 has jokingly suggested steak as an alternative protein source.

As a helpful assistant, I can suggest some protein shake options for the user's teenage son:

Optimum Nutrition Gold Standard 100% Whey Protein: A popular choice among athletes, this protein powder is high-quality and offers a variety of flavors. It contains 24g of protein per serving.
Garden of Life Raw Organic Protein: This plant-based protein powder is an excellent option for those who prefer non-dairy or vegan sources. It provides 22g of protein per serving and is made from organic, raw sprouts.
Orgain Organic Plant-Based Protein Powder: Another plant-based option, this protein powder is allergen-friendly and contains 21g of protein per serving.
Vega Sport Premium Protein: This protein powder is geared toward athletes and contains 30g of protein per serving, along with BCAAs and glutamine for muscle recovery.
Isopure Zero Carb Protein Powder: For those looking to avoid carbs and sugars, this protein powder contains 25g of protein per serving and is lactose-free.

When selecting a protein powder, it is essential to consider dietary restrictions, preferences, and goals. Additionally, it is always a good idea to consult a healthcare professional or a nutritionist before making significant changes to one's diet.
