With modern day food our nutrition is unavoidably insufficient, since most of the food comes from depleted fields or totally artificial growing environments, such as greenhouses. The normal daily intake of nutrients from the food is generally well under the optimum; the minimum or “recommended” levels are a completely different matter.
You can achieve the optimum nutrition level by taking a broad spectrum multi-vitamin and mineral capsule twice a day. Men should have their D-vitamin level over 120-150 nmmol/l (need to take min. 100-150 mcg/day), and take vitamin E at least 50 mg, vitamin C 500 mg, magnesium (Mg) 600 mg, zinc (Zn) 15 mg and together with that copper 1/7 th part of Zn, selenium (Se) 200 mcg, and strong multi B vitamins including 1 mg of B12 in mouth melting form.
On days when you are not eating fish, it is wise to take 1–2 g Omega 3 in fish-oil capsules. In the long run, this will keep the veins and arteries in better condition all over the body and prevent number of problems and inflammation.
