Lipoprotein (a) Cholesterol Control - Linus Paulin Formulation for blood vessel health
Verified purchase
I take this due to high Lipoprotein (a) cholesterol running in my family and in my body. this composition was discovered by scientist late 2 times Nobel price winner Dr. Linus Paulin and i have since reduced by blood level Lipoprotein (a) by 60%, this is a very effective solution in one buttle. also eating high collagen food along with vitamin C can also produce similar result. but this composition is easier.

I started taking this duo for skin and joint health, but the real win was how it helped my cold sores—when I feel that dreaded tingle, mega-dosing these amino acids actually shortens outbreaks. The 550 mg tablets are easy to split (no weird taste), and I love that it’s a simple, no-filler formula. After months of use, my nails are stronger, and my skin feels more resilient too.
