I'm Breastfeeding 15 Month Old Twins, They Also Eat 3

I'm breastfeeding 15 month old twins, they also eat 3 meals a day. Would it be safe for me to take Great Lakes Gelatin Collagen Hydrolysate as well as a bit c supplement that's 1000 mg/ a day.
I'm wanting to take it because I want to regrow fallen hair, tighten my skin for anti aging effects, and strengthen my teeth.. as well as improve digestion.
