Bulletproof

Bulletproof made its name with butter coffee and biohacking, but their collagen and protein products have become the quiet workhorses of their product line. Founded by Dave Asprey, the brand appeals to people who want to optimize their health with premium, science-adjacent products. Their Collagen Protein and Collagen Peptides are sourced from grass-fed, pasture-raised cows and dissolve almost completely clear in hot or cold liquids — no clumping, no taste, no texture issues.

For women on GLP-1 medications, Bulletproof's collagen products are worth serious consideration. Collagen peptides are among the gentlest protein supplements you can take — they dissolve invisibly into coffee, tea, soup, or water, which means you can add 11 grams of protein to beverages you are already drinking without changing the taste or adding volume to your stomach. When nausea makes the thought of drinking a thick protein shake unbearable, stirring collagen into your morning coffee is often still manageable. The downside is that collagen is not a complete protein (it is low in certain essential amino acids), so it should supplement your diet rather than replace all your protein sources.

Bulletproof also offers protein bars with 12 grams of protein each, which can be useful as a portable option on days when your appetite allows solid food. The brand's 120-day cookie tracking on their affiliate program is one of the longest in the industry, which says something about their confidence in converting browsers to buyers.
