Healthy aging.

I take amino acids and collagen for muscle and skin. I believe supplements, diet and exercise contribute to my good health.

Anti-aging starts within

I'm going to include Glutathione in this review because the combination of L-Proline & Glutathione has improved my skintone. I'm 55, figure that if I eat right, exercise, etc. at least 80% of the time, I can make up for infractions 20% of the time. Swanson has been helping me stay healthy & youthful for some time. Anyone can make claims, but unless you try something & stick with it for at least a season, how will you know? My body uses up nutrients very quickly, & supplements prevent the daily wear & tear that ages the body inside & out. Both L-Proline & Glutathione have helped me maintain elasticity & adjust to environmental exposure. I work outdoors, use SPF's, drink water, do the do's... but these two products keep my skin looking & feeling smoother & youthful. Combined with regular stretching, exercise & smart topical products, there is every reason to age gracefully.

Proline is a part of my waking up in the morning

I have taken Proline over the last three or four years and have believed it to help me through each new day. I feel better after taking it and Swanson brand offers a Proline I can count on. As being one of my three aminos that I have by my bedside, I take it with water every morning upon greeting each new day. This is my daily amino "coffee" before my real coffee is served! Swanson's Proline is priced far more reasonably than other brands and delivers what my body needs.
