Fogelholm, M. Ruokonen,I., Lack of association between indices of vitamin B1,
B2 and B6 satus and exercise-induced blood lactate in young adults. Int. J.
Sport. Nutr., 1993 June, 3:2, 165-75.
-This was a 5 week study on vitamin B-complex supplementation. Associations were made between
indices of B1, B2, and B6 status and exercise - induced blood lactate concentrations were studied along
with AC for erythrocyte transketolase. The conclusion was that high AC's do not predict altered lactate
metabolism.

Soares, M.J., Satyanarayana, K., The effects of exercise on the riboflavin status
of adult men. Br. J. Nutr. 1993 March, 69:2, 541-51.
-This study was done with six men who had riboflavin deficiencies. The subjects performed exercise
periods for eighteen days. The result suggest that riboflavin status further deteriorates during a short period
of increased physical activity in individuals with marginal status in riboflavin.

Singh, A., Moses, F.M., Vitamin and Mineral status in physically active men:
effects of high potency supplementation. Am. J. Clin. Nutr, 1992 Jan. 55:1, 1-7
- Changes in nutritional status during supplementation with a high vitamin supplementation were examined
in 22 physically active men. The urinary excretions of these vitamins increased during supplementation and
approximately 2 weeks later the values returned to the presupplementation values.

van der Beek , E.J., ET AL, Thiamin, riboflavin and vitamin B6: impact on
restricted intake on physical performance in man. J. Am. Coll. Nutr., 1994 Dec.,
13:6, 629-40.
-The functional effect of the restriction of thiamin, riboflavin and vitamin B6 was investigated. The
conclusion was the absence of vitamin specific effects on performance decrements due to restrictions
suggests similar effects on B vitamins on mitochondrial metabolism.

Rokitzki, L., ET AL, Pantothenic Acid levels in athletes at rest and after aerobic
exercise. Z Ernahrungswiss, 1993 Dec, 32:4, 282-8.
-96 high performance athletes were investigated. It was found that during exercise there was a significant
increase in the pantothenic acid levels in marathon runners.

vitamin B6 supplements in elderly people with normal serum vitamin
concentration. Lancet, 1995 Jul. 8,346:8967, 85-9.
- The response rate to vitamin supplementation supports the notion that metabolic evidence of vitamin
deficiency is common in the elderly, even in the presence of normal serum vitamin levels.

Higgins, C, Deficiency testing for vitamin B12 and Folate. Nurs Times, 1995, May
31-Jun. 6, 91:22, 38-39.
-Vitamin B12 and folate are necessary for the production of red blood cells. The measurements of these
vitamins are useful in the diagnosis of anemic patients,

Quin, K., Basu,T.K., Folate and vitamin B12 staus in the elderly. Eur. J. Clin.
Nutr., 1996, June 50:6, 340-342.
-The folate status appears to be a greater concern than the B12 status for the elderly population. The older
population seems to be at risk.

Swain, R., An uptake of vitamin B12 metabolism and deficiency states. J. Fam.
Pract., 1995, Dec., 41:6,595-600.
-Vitamin B12 deficiency may be underestimated in the population. This deficiency can be treated with
monthly injections or large oral doses of supplements.

Suzuki, M., Itokawa, Y., Effects of thiamin supplementation on exercise - induced
fatigue. Metab, Brain, Dis, 1996 Mar., 11:1,95-106
-High thiamin supplementation may be helpful in preventing exercise - induced fatigue. The
supplementation suppressed the increase in blood glucose in the normal thiamin group and also decreased
the number of complaints after exercise.
