Periconceptional folic acid (FA) reduces neural tube defect (NTD) risk, but seems to have a varying effect per NTD subtype. We aimed to study the effect of FA supplementation on NTD subtype distribution using data from EUROCAT Northern Netherlands. We included all birth types with non-syndromal NTDs born in 1997-2012. By Fisher's exact test we analyzed possible differences in NTD subtype distri...

conclusions beta-alanine supplementation has limited antioxidant effect during the repeated wts. background carnosine is a dipeptide formed from the β-alanine and histidine amino acids and found in mainly in the brain and muscle, especially fast twitch muscle. carnosine and creatine has an antioxidant effect and carnosine accounts for about 10% of the muscle's ability to buffer the h+ ions prod...

Studies of dietary supplementation and cancer risk are full of surprises. Ten years ago, most epidemiologists and nutritionists sincerely believed that fl-carotene was the leading candidate for evaluation in chemoprevention trials. We now know that (3-carotene supplementation among smokers increases the risks of lung cancer, cardiovascular disease, and total mortality (1, 2). Although the story...

UNLABELLED Antioxidants can decrease oxidative stress and combined with acute exercise they may lead to further decreases in blood pressure. The purpose of this study was to investigate the effects of 2 weeks of antioxidant supplementation on vascular distensibility and cardiovascular hemodynamics during postexercise hypotension. METHODS Twenty young subjects were randomized to placebo (n = 1...

Although physical activity and creatine supplementation have been a documented beneficial effect on neurological disorders, its implications for epilepsy are still controversial. Thus, we decided to investigate the effects of 6 weeks swimming training, creatine supplementation (300 mg/kg; p.o.) or its combination seizures and neurochemical alterations induced by pentylenetetrazol (PTZ). We foun...

The aim of this commentary is to review data on the effect of supplementation of paediatric patients ages 2 years or older with n-3 long-chain polyunsaturated fatty acids (LCPUFA). Some evidence for a positive effect on functional outcome in children with attention-deficit/hyperactivity disorder (ADHD) was found; however, benefit was seen in only about half of the randomised controlled trials (...

Iron deficiency anemia (IDA) is the most common nutritional in India, which managed with oral supplementation of iron. Gastritis induced these iron pills a complication following (ferrous sulfate) supplementation. So proper care must be taken when prescribed. When side effects are encountered, stopped, and treatment should started immediately.

UNLABELLED Beta-alanine supplementation has been shown to improve exercise performance in short-term high-intensity efforts. However, whether supplementation with beta-alanine is ergogenic to actual sporting events remains unclear and should be investigated in field testing or race simulations. PURPOSE The aim of this study was to assess if beta-alanine supplementation could improve 2,000-m r...

The impact of 25-hydroxyvitamin D (25[OH]D) supplementation on weight change remains controversial. The objective of this study was to summarize the effects of 25[OH]D supplementation (cholecalciferol or ergocalciferol) on BMI change through a meta-analysis of published clinical trials. We completed a systematic review of English articles, using MEDLINE (Ovid, Pubmed) from January 1, 1998 throu...

BACKGROUND The use of creatine (Cr) as a nutritional supplement to aid athletic performance has gained widespread popularity among athletes. However, concerns have recently been expressed over potentially harmful effects of short and long term Cr supplementation on health. METHODS Forty eight young healthy subjects were randomly allocated to three experimental protocols aimed at elucidating a...
