Collagen production and immune health are always working in the background, and the demands on both change with every stage of life. Formulated by a team of leading OB/GYNs and nutritionists, Collagen+ Defense combines collagen peptides with animal-free lactoferrin to support your immune health, hair, skin, and nail health, joints, connective tissue, and energy every day.*
Collagen peptides support joint comfort, structural integrity, and connective tissue throughout pregnancy, postpartum recovery, and beyond. Lactoferrin, colostrum's multitasking protein, supports proactive immune health and helps your body absorb and use iron more effectively from food and supplements.*

- AJAlexis J.Verified ReviewerRated 5 out of 5 stars1 minute agoLoving it
This has been a go-to in smoothies! It blends seamlessly and I'm taking iron so I love knowing I'm getting an extra boost. I trust everything Perelel makes fully!
- AKAlison K.Verified BuyerRated 5 out of 5 stars22 hours agothe health boost I didn't know I needed
everyone should add this to cart and add it to your morning routine. I stir it into my americano every morning and it completely disappears - no texture, no flavor, just benefits. Looking forward to seeing how well it holds up against cold and flu season, but based on other reviews I'm looking forward to a healthy winter!
- KMKayla M.Verified ReviewerRated 5 out of 5 stars2 days agoBig fan!!!
I have loved adding this to my morning smoothies! I especially love that it has lactoferrin. That is such an added bonus!
- OHOnriela h.Verified BuyerRated 5 out of 5 stars2 days agoAmazing
Great flavor and taste. Great results
- RRosieVerified BuyerRated 5 out of 5 stars4 days agoA must for postpartum
I take this every single day and am positive it’s keeping me healthy for my baby during cold and flu season. Tastes like nothing, easy to mix it. I usually combine it with my Cellular Hydration.
