Nestmann Lappa Review

This product is a liquid extract sold as Lappa, which is burdock. The label lists only a proprietary liquid extract blend of 1 milliliter per serving and does not name its contents or amounts. None of the studies we have tested burdock or this product, so there is no direct human evidence that it slows aging or repairs cells. The studies linked to it tested different blends. A pomegranate rind and cocoa seed blend at 200 or 400 milligrams a day for 8 weeks improved grip strength, raised testosterone and lowered aging symptom scores in men aged 36 to 55 compared with placebo ^[1]. A Chinese skullcap root and black catechu blend at 300 milligrams twice a day for 30 days helped adults process complex information faster and more accurately than placebo ^[2]. A small study without a comparison group found that a collagen and antioxidant supplement improved wrinkles, pores, hydration and firmness in 34 women over about 2 months ^[3]. These results come from other ingredients and should not be read as evidence for burdock. No study measured biological age. Animal and cell studies are never counted.

All three cited studies tested unrelated extract blends (pomegranate rind and cocoa seed, Chinese skullcap and black catechu, collagen with antioxidants), not the burdock (Lappa) extract in this product, so they cannot support a tier 2 grade. So it is graded Tier 4, lower than the rules alone gave.
