Wouldn't buy again
Not worth the premium — comparable products cost less per serving. Needs a blender to mix properly, a shaker just doesn't cut it. Ingredient list has more fillers than I'd like for the price.

Resealable tub keeps everything fresh and the scoop sits right on top. Zero clumping, which I appreciate since my old one needed a whisk every time. Finally one that doesn't taste artificial. The vanilla is subtle and pleasant. Wish the dosing were more transparent instead of a proprietary blend.
Sleep quality went up almost immediately, which is exactly what I wanted. For what you pay, the ingredient quality is excellent. You can tell this is a quality formulation; transparent labeling and third-party tested.
Packaging felt flimsy and one tub arrived slightly dented. Flavor is bland at best, slightly chemical at worst.

Dr. Rath. Designed to help support the cellular health and stability of connective tissue in the body.* Key Synergy Nutrients: Vitamin C, L-lysine, and L-proline. Vitamin C: Vitamin C is also a powerful antioxidant that neutralizes free radicals. Unlike animals, humans do not produce vitamin C, so proper supplementation is vital for the health of connective tissue.* L-lysine: An essential amino acid, is a building block of collagen. L-lysine helps maintain healthy connective tissue. L-lysine is not produced in the body and supplementation is necessary to help protect support of the body's connective tissue.* L-proline: Another amino acid, is a building block of collagen that also strengthens the body's connective tissue. This nutrient is produced by the body in limited quantities, so additional supplementation is important to ensure the optimal production of collagen.*
