Vital Proteins Collagen Peptides.
Great for skin, hair, nails and joints and a great gift for someone you love who might have issues here or just simply likes functional foods. I add it to my coffee, you can add it to smoothies.
The one I use is made from grass fed beef collagen and is full of amino acids. Note** They also make a marine collagen peptide if that interests you.
As always, available on Amazon:
