Robert Wiblin has reviewed the literature and for a healthy person, recommends the following:
- Vitamin D3 (10µg or so a day)
- Creatine (5g a day)
- Zinc (30-160mg and Vitamin C (>1g) each day for the duration of colds.
He adds: If I were particularly worried about my blood pressure or cardiovascular health I would start
- taking Omega-3
- limiting my salt intake, though this isn’t certain to work
- replacing saturated fat with unsaturated fat
- taking a lot of garlic.
However, I am young, and consider heart disease to be a problem for the future.
