Positive experiences
“Within hours of consumption my consistent upper back pain is literally gone, but along with it comes dizziness and a feeling of aloofness.”
“Vitamin C(100-200mg) + hydrolyzed collagen peptides(15g) 1 hour before eccentric squats on a 25 degrees slant board should be a start. It has helped me.”
“5g collagen [in stack]... skin is grabbing me tighter... apron belly has drastically decreased.”
“For joints and tendons I've had good success with 20 g collagen, 5 g glycine and 500 mg vitamin taken about an hour before stressing the joints. Really helped my knees with long distance running.”
“I've been using the collagen from Sports Research and noticed an improvement in the thickness of my nails. I also have some joint pain and it seemed to ease it.”
“You're probably going to need upwards of 15g/day... Personally, massive improvement in my joints.”
Negative and mixed experiences
“My knees were getting rather janky and then I started the collagen and in a few months, they were 95 percent better.”
“I stopped taking collagen powder after years... I used to find I'd get a histmaine episode after taking it sometimes, and get the lethargy.”
“Taking collagen fixed my creaky badminton knee, and it definitely makes a difference on my skin texture.”
“I take mine a scoop in oatmeal 2x a day and a scoop in kefir before bed. Biggest benefit is improved sleep.”
“after a couple of weeks of it I get super energised...and my anxiety is much reduced.”
“a decent dose (~15g - 20g) of Collagen improves my sleep noticeably (while also improving skin health and I assume other benefits)”
