Everyone’s adding collagen to their smoothies, coffees, and even their skincare. But is collagen actually the secret to youthful skin and strong joints — or just expensive hype?

In this episode, I break down the real science behind collagen:

What collagen is and why it matters

What peer-reviewed research actually says about skin, joints, and muscle

Which forms work (powder, capsules, shots) and which don’t

What to look for when buying a supplement

How much to take, how to take it, and when it’s worth it

If you’ve ever wondered whether that $2 collagen shot at Joe & The Juice is worth it, this episode will give you the no-BS answer.
