Alpha Lipoic Acid
WHY THIS ONE

Most antioxidants work in either water or fat. Alpha-lipoic acid works in both, which is why it reaches tissue the others cannot, and it regenerates other antioxidants instead of being used up itself. A full 600 mg in one capsule, the amount the neurological...

Beet Nitric Oxide
WHY THIS ONE

Beet root is rich in dietary nitrate, the compound your body turns into nitric oxide — the molecule that tells blood vessels to relax. But nitrate in beets varies wildly from crop to crop. This is SABEET®, a concentrated extract standardized to a guaranteed...

Berberine Phytosome
WHY THIS ONE

Berberine's problem was never potency, it was absorption. Berbevis® binds it to sunflower phospholipids so far more of it actually reaches your bloodstream, which is why 550 mg here does the work of a far larger conventional dose. Two capsules a day. Independently tested,...

Boswellia Phytosome 500 mg
WHY THIS ONE

Boswellic acids are the reason people have burned frankincense for three thousand years, and on their own they are poorly absorbed. Casperome® binds them to sunflower phospholipids so more of the resin's actives get through. Five hundred milligrams in a single daily capsule, for...
