Collagen Peptides Mentioned in This Video:

Links are commissionable at a whopping 1% on Amazon, which is about $0.30-0.40 cents per sale. I applied to be a Great Lakes Wellness Affiliate but they said I am not a good fit for the brand. 😃
I don’t think they like me telling people they can take 25% of their recommended daily dose.

Here’s what you’ll learn:

– What the latest research really says about improving wrinkles, hydration, and elasticity
– Six key things to look for before buying a collagen supplement
– My personal results after 1 year* of taking collagen — the unexpected benefits and what didn’t change

*It’s actually been closer to 1.5 years since I started taking these supplements, but that’s not as catchy, is it?

I’ll also share my two favorite collagen peptide products, how to get the best value for your money, and what factors matter most.

Marine collagen and contamination:
I prefer fish SCALE (versus fish skin) as a source for marine collagen, as it is low fat. Persistent Organic Pollutants (POP) like dioxin are more likely to accumulate in fatty tissues, which fish scale is NOT.
