Objectives: The purpose of this study is to assess the amount of water soluble and fat-soluble vitamins in seaweeds as a contributor to daily intake for adults.
Methods: A full text, English only publications was searched on PubMed and Google Scholar, published within 2016 to 2022. Two search terms were utilized on PubMed, the search resulted in 7 and 781 studies. Out of these studies, three met pre-determined eligibility criteria for inclusion. On Google scholar, the search resulted in 17100 studies. Out of sixty studies, two studies met the pre-determined eligibility criteria. The total relevant publication summed up to five studies.
One randomized control trial study design was used for one study. The remaining four studies utilized varied study designs: one observational study designs, three cohort study designs, four cross sectional study designs, and one systematic review study designs. The composition of seaweeds was compared to other dietary sources and nutritional intakes.
Results: Seaweeds are a better source of vitamin C compared to iceberg lettuce, although not an abundant source of vitamin C for food consumption. Seaweeds are an alternative source of vitamin B12 for the vegetarian population, and Vitamin A (carotenoids) found in seaweeds was relatively higher than in carrots. The vitamin A content varied from 2-10% of Reference Nutrient Intake [RNI]). The vitamin C content varied from 1-23% of RNI & vitamin B12 content varied from 107-446% of RNI. Seaweeds have great potential as potential food supplements and may be used in the food industry as a source of ingredients with an appreciable amount of nutritional value.
Conclusions: In comparison to the recommended dietary allowance, seaweeds can contribute to the daily intake for some vitamins such as vitamin B12, C and A.
