I started using lanolin on my skin as a sunscreen, (chemical free, soy free sunscreen) as lanolin is the basis of Vit D3 supps, my 1-2 hours in the sun each morning with lanolin on my skin, is a Vit D3 producing factory!!
now that the other deficiencies like magnesium etc are fixed, my body is better at 'making' Vit D3.
I am finding the lanolin is far better as skin moisturiser than coconut oil.
good for you doing the 23andme testing .... the methylation report from Genetic Genie will provide reasonable info... and they provide a bit of a summary based on your results.
there are quite a few websites that have additional info about genetics snps/mutations and what it means for the methylation cycle...
I was very interested to find out that due to my mutation mix, i need both forms of B12 ....

Lots of the web sites that discuss natural approach to Thyroid, discuss or link to good info about the methylation cycle...
I have found some other reporting sites that can take the 23andme data and provide some cool reporting!!
I am also in email contact with people that I share DNA with - to see if we are blood line cousins!
