| Fruits in a pill!? No panacea, after all. |
Its always nice to see studies done on real world supplements, such as the one published by Goldfarb et.al. (
Goldfarb. 2010) in the latest issue of
Medicine & Science in Sports & Exercise. Over a period of 28 days prior to a bout of excentric exercise (and for the following four days) the scientists supplemented forty one (18-35 yrs) healthy volunteers randomly with either a placebo (P) or 6 caps of
Fruit Juice Plus (FJC) per day. After all subjects had completed 4 sets of 12 repetitions of eccentric elbow flexion with their non-dominant arm blood samples were taken. While FJC had
no measurable effect on exercise performance, muscle soreness , range of motion (ROM), maximal isometric force (MIF) of the elbow flexors, creatine kinase (CK), and
lipid hydroperoxides (LOOH), ...
there was a significant time and time by treatment effect for plasma protein carbonyls (PC) and malondialdehyde (MDA). PC and MDA increased over time in the P group (p<0.01) but were not significantly altered in the FVC treated group at any time.
This lead the scientists to conclude that...
4 weeks of pretreatment with a FVC can attenuate blood oxidative stress markers induced by EE but had no significant impact on the functional changes related to pain and muscle damage.
In view of the fact that a
standard multi-vitamin would probably have performed, as well, you better save your money for more valuable investments.
