Raspberry Key follows the exact same structure of claims as any other raspberry ketone product on the market, including no fillers, binders or artificial ingredients. Dosed at 500 mg per capsule it does meet a high standard but it does not address the critical absorption issues that plaque most supplements. Physicians Reference Desk reports only 10-20% of most supplements are absorbed properly into our bodies, meaning we are throwing away the other 80% down the toilet, literally. For this reason it is critical to find a supplement that leverages absorption technologies, capsacian, thermo-nutrients, etc… to address this problem. It cost more but will worth it!
