Bioactive Alpha-Tocopherol
Vitamin E is a group of 8 different compounds: 4 tocopherols and 4 tocotrienols, each distinguished by the prefix alpha, beta, gamma or delta.
Of all forms of vitamin E, alpha-tocopherol has the highest bioactivity. It is also the only form recognised as fulfilling vitamin E requirements in humans; all other forms of vitamin E are measured against alpha-tocopherol.
The molecule alpha-tocopherol occurs in several geometric variants. Natural alpha-tocopherol always takes the form of RRR-alpha-tocopherol (formerly referred to as D-alpha-tocopherol), and only this form exhibits the desired biological effects on the body. Synthetic vitamin E, typically a combination of various isomers, is less bioavailable and bioactive. Our liquid multivitamin drops provide only natural, bioactive RRR-alpha-tocopherol.
