Unexpected benefits with bladder control

I have been pleasantly surprised. I initially bought this product to help with dry skin and brittle nails, which I have seen a little difference with. What I didn’t expect was the help it’s provided with bladder control. After carrying several babies, I started experiencing some bladder issues - typically when laughing hard or some other strenuous activities (heaven forbid I join the kids in the trampoline...). My doc and I have discussed surgical options - but I just wasn’t ready to go that route. I started taking the collagen supplement and noticed a difference in that area within a week. I ran out and forgot to order more, and it reverted back within a few days. I started taking the supplements again - and was able to gain back the control. I realize this may not help everyone in this way - and maybe it won’t help me long term - but it’s helping now and so worth every dime. I’m so happy with this unexpected side effect!!

Still Loving It — On My Second Bottle!

Verified purchase

on my second bottle of Ancient Nutrition Collagen and can honestly say it’s made a real difference. Im in my 40s but using this makes my skin feel smoother, my nails are stronger, and my joints feel less stiff — especially in the mornings. I like that the capsules are easy to take and don’t have any weird aftertaste. Great quality. Definitely staying consistent with this one — it’s become part of my daily routine!

Good product

Verified purchase

I am really impressed with the quality of this supplement. I've also tried various other products from this brand, and I consistently find their ingredients to be effective and reliable. So I gave it 5 stars because Dr. Mercola has a lot of research behind all of his products. The conclusion is that this product has a superior quality. Can't really tell yet as it's too soon since I started taking it but this might be worth it. Overall, it's a valuable addition to my wellness routine. Size and age 👍

High-quality multi collagen blend

Verified purchase

Excellent collagen supplement with a well-rounded blend. Easy to take, gentle on digestion, and made with high-quality ingredients. With consistent use, I noticed improvements in skin hydration and overall joint comfort. Capsules are convenient and don’t upset the stomach. A great option if you want a comprehensive collagen formula.

I love this collagen supplement! After a few weeks of use, my skin feels more hydrated, and my nails are much stronger. I also noticed less joint discomfort, especially after workouts. The capsules are easy to take, and I appreciate that it combines multiple collagen types for better overall benefits. Definitely recommend it!

This is Working!

Verified purchase

I recently switched to this collagen on the advice of my family member who gets it from her NP. In the last few years my hair was thinning a lot so I began taking this about 2 1/2 months ago and I have noticed that my hair is coming out much less. It will take about a year or so to see if this continues and my hair thickens up but I am extremely hopeful at this point based on what I have noticed already. I am in my mid 60's. I would have given 5 stars but I want to make sure that these results continue. I definitely recommend this collagen since it is working better than anything else I have tried.

It’s not easy to find a complete collagen supplement that provides all five sources. I couldn’t recommend this high quality product more. I was looking for something to promote healthier joints, skin and digestion and after a few weeks of use , I saw a substantial improvement. Definitely found it beneficial 👍🏼
