Telomind is made from authentic Fertilized Incubated Avian Egg Extract, sometimes referred to as FIAEE, in a powerful proprietary supporting formula of alkaline botanicals and amino acids for your enhanced sense of well-being. What's the reason other companies don't include YTE? This is a very rare, premium, natural ingredient which is expensive to produce. We're a small family business happy to make less margin and provide the very best immunity and energy supplement, with genuine ingredients always at the right dose. Don't risk using a formula with fake, dangerous or unethical ingredients; don't waste time and money on overpriced alternatives which don't contain genuine YTE at the right dose.
