I’ve never had any problem with my nails– until now that is. In the past six weeks my nails have gone from strong and shiny to soft and brittle. I’ve tried two different nail hardeners with no luck. Doing a little online research, I learned that low levels of Biotin are linked to broken nails. This is not a rumour or an urban nutrition myth, but a link backed up by well designed peer reviewed studies.
Best sources of Biotin are eggs, soy beans and nuts. Ah a clue! I try to avoid soy products, limit nuts ( calories) and since the summer salmonella outbreak, avoided all eggs. Since my nail problems started six weeks ago and it takes several months for nutritional deficiencies to show, the timing is right.
There are nail care products formulated with Biotin, but since nails cannot absorb vitamins from the surface, this is not an option. My solution? Add biotin to my diet. My choice is increasing food sources food sources or taking a biotin supplement. Normally I would add biotin rich foods like a couple of hard bolied eggs. Most nutritional studies have shown that the health benefis of a nutrient are only available from food sources rather than a pill. However biotin is one of the rare nutrients ( vitamin C is another) that can be effective in a supplement.
So now the question becomes — how much biotin do I need? There is no RDA for this b-vitamin, so how do I know how much I need? Or for that matter how much would be too much? Have you ever tried biotin for your nails? How much did you use?
