I used to take this once a day(one tablespoon) many years ago and took I it for about four months and got off track with it so Ive purchased it again.It does wonders for the skin and hair!If you have brittle nails,thin brittle hair,cellulite,weak tendons this is perfect to take internally.You can also use it externally for superficial minor injuries and skin problems: minor cuts, skin cracks, abrasions, minor burns,scalds, sunburn.In a few weeks you start seeing results.Hair and nails become much stronger and the skin gets healthier looking.Take one tablespoon a day either straight or mixed through water.It is tasteless but quite gritty I always mix it through water or juice.It is the consistency of a gel.For external problems just dab on problem spots.I highly recommend this if you want healthier skin and nails,just be sure to be committed to taking it every day to see results.
