Kids and adults have different nutritional needs, and need to be supplemented accordingly. The whole family can share a general multi-vitamin – if you or your kids still have that infamous luminous yellow liquid in the toilet bowl, split your dose and take it twice in the day. We can only absorb a certain amount of nutrients in one sitting, so splitting your vitamins to take a morning and evening dosage means maximum absorpotion. Personally, I trust Foodstate vitamins like Sportron.
Then, men need to take Omega 3 capsules daily to ward off heart disease, and women need calcium and a combination of Omegas to keep bones and joints strong. All family members will benefit from a vitamin C supplement in varying forms, to boost immunity.
