"The good: I've been taking these for about a month, and have been taking biotin for about 3 months now. My hair is definitely looking a lot thicker. I'm finding much less hair in the drain filter screen. That said, I'm not sure if it's the biotin or the collagen pills ... or both ... that are helping my hair.

The unsure: I'd also hoped that these would help with pain. One of my Achilles tendons has been giving me a fit, and it seems to be better. Whether it improved on its own, or whether these pills helped ... I don't know. I also have pain in my hands (arthritis?) and flare-ups of costochondritis (sternum/rib pain). It doesn't seem to have helped those issues so far, but I'm still hopeful.

The bad: These pills are GIGANTIC. I can't swallow pills anyway, so I knew I'd have to chew these up. The taste isn't bad, thankfully, but I have to break them in half and then chew each half separately using only my front teeth to carefully nibble them into tiny bits. If I try to chew a whole pill, it spreads over my whole mouth, and becomes extremely sticky and gummy. It gets stuck in my teeth, which is annoying. Also, a few days after I started taking them, there were some minor tummy issues. Those issues have gotten worse, to the point where I'm going to cut the dosage down and see if the problem resolves itself.

Will update if anything changes. :)"

"The first week I noticed new growth in terms of my hair. I had dyed it and literally 2-3 days later new growth which I knew right away it was working. Nails were harder and longer and cleared up some stretch marks which I honestly thought were never going away. Only bad thing about this product is that you have to take 6 pills daily which is horrible on GERD and not sure of the direct correlation but I use proactiv, however for some reason I still had acne breaking threw which I never had with another collagen product. It appeared to make my face specifically more oily. Other than it’s a great product and I think it may work differently with people."

"I’ve been taking these for over 6 months now. Just ordered a new pack as the last ones are running out so they do last a while. The bottle suggests taking 6 tablets per day, I was taking 3 in the morning and 3 before bed and had no stomach problems or other side effects but also wasn’t feeling like I was getting any results. Switched to all 6 in the am and making sure to take them each day. Also had no ill effects. Within a month, I started to get compliments on my skin including from my sister who is persnickety on that sort of thing. I’m 48 years old from the Southwest and have been outside a lot in my life (with and without sunscreen), had acne as a teen and still have some scars, always had oily skin on noes and cheeks. But now, my skin tone is more even, the oily patches have balanced out, and my pores are decreasing. I’m doing a couple different beauty routines so I can’t say all that is the collagen but I’m sure some of it is."
