MY husband always feels coldness even on summer, is macro C good for him? If so, how many tablets is he giong to take daily?

Yes Vitamin C is a well known cold killer and with Bioflavenoids, it is a good combatant for the cold and flu. I would think 1 a day would be enough, because moderation when taking supplements is a good thing and your body also needs the Vitamin C: www.myshopping.com.au/PT--209_Vitamins_Nutrition_Macro_Vitamin_C__fs_3995_22709_e__

Hi Rosie,
I'm assuming that by "coldness" you mean he always feels cold (as in temperature)? Vitamin C is a great supplement to take for general overall health and it does boost the immune system, but I'm not sure how much it would help with him being cold. I would be more inclined to suggest something to help with his circulation. There are several things out there that are great for this including (my favorite!) essential fatty acids in the form of fish oil. Not only is fish oil great for circulation, but it also helps to maintain overall good health. You'll probably want a high potency formulation. www.myshopping.com.au/PT--209_Vitamins_Nutrition_For_Men_Fish_Oil__fs_41_26842_e__
Ginko is another good thing for circulation, but be sure to consult your doctor on this one as it does have some contraindications with some medications and conditions. www.myshopping.com.au/PT--209_Vitamins_Nutrition_Poor_Circulation__fs_1695_e__?Find=ginko
You can also check out the general page listing all kinds of things for poor circulation. www.myshopping.com.au/PT--209_Vitamins_Nutrition_For_Men_Vitamins_Minerals_Poor_Circulation__fs_41_1680_1695_e__
Good Luck!
