How much vitamin D should I take?
Official UK advice is to consider 10 micrograms daily through autumn and winter. Higher doses are available and best taken on advice rather than by guessing.
Does garlic really need to be stabilised?
Allicin is fragile and most garlic capsules lose it in processing. Stabilised allicin products are made specifically to retain it, which is what you are paying for.
Can I take vitamin C and zinc together?
Yes, and many formulas combine them. Just add up the totals if you also take a multivitamin - zinc in particular has an upper limit.
When should I start?
Most people begin as the clocks change. Vitamin D in particular is taken right through autumn and winter rather than started once you already feel run down.
