  • Bio Synergy Performance L-Glutamine x 90

    Bio-Synergy L-glutamine capsules are the ideal daily supplement for anyone participating in endurance (such as long cycle, run or swim) or strength based activity. The science:

    L-glutamine is the most abundant amino acid in the body and plays a significant role in muscle recovery. Many endurance and strength athletes often suffer from muscle fatigue which cannot only hinder optimum performance but delay recovery too.

    Beat the bonk with L-glutamine

    L-Glutamine has been unveiled as the ‘everyman’ supplement, holding a use for all athletes and weekend warriors.

    L- Glutamine is quite common in everyday foods, and our body holds onto stores of it already, so you’re not taking in some un-natural substance, in fact you had it in you all along.

    The benefits of L Glutamine are similar to other amino acids, in that they offer a ‘reserve supply’ effect, allowing you to carry on stronger for longer, without depleting levels.

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
