The expense of fish can make it a seasonal dietary choice. Eat it as a treat when the sun does not shine. Other dietary considerations like cod liver oil can also be used to supplement your dietary intake.
A contrarian view of the traditional supplement industry recommendations would be to only take for three days on and two off. Or to make it easier, take them Monday and Tuesday, off Wednesday and Thursday and on again Friday. Any combination so that there are a few days off in between.
The rational for this is three fold.
1) This is the basic avoid food allergy regimen.
2) If you cannot afford it, you will not do it. Spacing will make it more affordable.
3) Your body will not take or store more than it needs.
Increase the days when dealing with illness, stress, needing extra mental agility or will face physically stressful situations.

In addition to foods high in vitamin D, there are other ways to boost your intercellular glutathione.
