I have run to completion 12 Ironman races, the Western States 100 miler, the Hawaii Ultra Man Championships, the Coastal Challenge and an assortment of 24 hour adventure races. I am probably considered an endurance athlete. I once owned a health food and supplement store, I did an awful lot of reading research and self experimentation. Without being too scientific and simply answering your question. I supplement:

Omega 3 EPA & DHA
Glucosamine Sulfate 500
Zinc 30 mg
Acetyl L Carnitine 250
Vitamin C 1000
Lipoic Acid 200mg
Vitamin E 400 IU
Chromium Picolinate 200 mcg
Co Enzyme Q10 30 mg
Calcium Magnesium 1:1 500

Thanks for asking :)

WOW! thanx for the reply!

Please do get scientific! What did you use those things for and what was the timing etc :lol:

Search for more information about Adaptogens!

Looa at:

Thanx for those links. The adaptogens seem a little 'under scientifically backed.' Plus they are relatively hard to get hold of for the average endurance trainer.

Anyone else want to through in a supplement that they have used or heard of being effective? The list above was great but an explanation of why these are used would be good here are my thoughts

Omega 3 EPA & DHA - General health, body re-comp
Glucosamine Sulfate 500 - Joints
Zinc 30 mg - not sure of zincs specificity to endurance....?
Acetyl L Carnitine 250 -
Vitamin C 1000 - Immune function
Lipoic Acid 200mg - As in Alpha lipoic acid....anti oxidant
Vitamin E 400 IU - anti oxidant
Chromium Picolinate 200 mcg - Not sure..........
Co Enzyme Q10 30 mg - Is this an anti-oxidant too?? :?:
Calcium Magnesium 1:1 500 - Not a clue to the link to endurance
