Evidence from the literature suggests that dietary flaxseed lignans have the ability to modulate inflammation, which is recognized as the underlying basis of multiple chronic human diseases in older adults. Our objective was to determine the effects of oral lignan supplementation on biochemical and functional indicators of inflammation as well as safety and tolerability in older healthy adults. We designed a randomized, double-blind, placebo-controlled clinical trial in older healthy adults (60-80 years) to assess flaxseed lignan-enriched complex (∼38% secoisolariciresinol diglucoside [SDG]; 600 mg SDG dose) oral supplementation effects on biochemical and functional indicators of inflammation and safety and tolerability in older healthy adults after 6 months of once-daily oral administration...

OBJECTIVE: β-alanine (BA) is a nonproteogenic amino acid that combines with histidine to form carnosine. The amount taken orally in individual doses, however, is limited due to symptoms of paresthesia that are associated with higher doses. The use of a sustained-release formulation has been reported to reduce the symptoms of paresthesia, suggesting that a greater daily dose may be possible. The purpose of the present study was to determine whether increasing the daily dose of BA can result in a similar increase in muscle carnosine in a reduced time...

BACKGROUND: Increased plasma homocysteine (Hcy) levels are a risk factor for stroke and can be reduced with folic acid therapy. Therefore, it is extremely important for patients with hyperhomocysteinemia (HHcy) to obtain the normal level of Hcy after folate intervention. Thus far, few studies have reported the effective rate defined as percentage of patients who achieved normal plasma Hcy levels after folic acid therapy. OBJECTIVES: The present study aimed to investigate the effective rate of folic acid for the treatment of HHcy and the impact of plasma baseline Hcy levels and the compliance of oral folic acid on the efficacy...
