So should you include collagen to your routine? Here’s the glass-half-full view: These minced collagen peptides seem to work– and impressively so. “Supplements are here to stay,” states skin doctor Doris Day. She argues that any product with such a strong medical result has a certain place in a wrinkle-fighting routine, together with an excellent diet, sun defense, and an anti-aging moisturizer. “Further independent studies are needed to see if the information is true,” she says. “But I believe we need to open our minds to more creative methods.”

    Hi Lorrainde,
    My problem is the opposite. I’ve been taking collagen peptide supplementation for four weeks and I’m constipated and wondering if the collagen/increased protein is causing it.

    Hi…I’m also opposite to Lorraine. I was fine on tablet collagen but switched to powder form as,was told more effective. Abdomen feels heavy and hot. I’ll persevere. Try for a month and see if it settles.

    B. I have been using powered collagen for 3weeks. Felt great at first. Not so now. Have leg cramps during the night, a lot of bone aches, very little energy. Also it has done nothing for my skin. Has anyone else had any similar problems? Im afraid i must consider sending it back.

    I’ve been taking powder collagen from amazon with the highest five star ratings and over three thousand of them. That alone made me pull out my credit card. Ever since I started taking it exactly as described I’ve been sooooo tiredddd and lethargic. My body feels like i have weights strapped to all of my limbs and I cannot wait until night time so I can lay down. I’m usually not a sensitive person and have always had an unusually high tolerance for a 5’1” and 114 lb person. Thought collagen was good for our bodies? I’m so confused. And majorly disappointed. My skin is so parched and getting thinner as I get older it’s in such need of something (that I thought was collagen) drastic that it’s missing to remain healthy. Could it be true that this is also the cause of my extreme fatigue? I wonder why all the other reviews had such extremely positive experiences. Also I am so constipated it’s awful. I will not take it tomorrow for a while to see if I start to feel normal again. Then back to square one with finding an efficient and dramatic skin care “something” to maintain. I’m only typing this incase someone else is searching on the internet for others having the same experience so they can compare and judge the cause. (Btw the brand is “physician’s choice collagen peptides”)

    I’ve been using collagen and it leave me constipated and started having skin rash. Don’t know if this is from the collagen. I’m going to stop and see if there’s a difference.

    I’ve been taking powdered college for 4 weeks daily in my coffee. The past two weeks I’ve become very constipated which has always been a problem but is worse since I started the collagen. I take a daily laxative and still constipated. I also notice I’m very fatigued at the end of the day and having a hard time exercising. The only good thing is I don’t get hungry but I still haven’t lost weight from eating less. I’m disappointed and plan on returning the unopened containers. It’s not what I expected.
