1. I don't go without our Ultimate Classic the multimineral-multivitamin liquid drink. If I could only choose one vitamin/mineral supplement, that'd be the one as it includes plant derived colloidal minerals for trace mineral supplementation, chelated or even colloidal chelate macrominerals, all my vitamins especially high doses of B complex, a high ORAC value, a proprietary amino acid complex like many supplements could use and several complimentary substances to the essential nutrients like glucono delta lactone, dimethylglycine and PABA. I get that product from my own site here: http://capacity.youngevityonline.com/
2. At the same site though it's not a vitamin or mineral, I take EFA capsules-I never take the loose oils and don't want them as part of my open vitamin/mineral supplement because they are very perishable. I've tried others from our line but generally stick with EFA Plus with fish oil due to the low conversion rates of strictly plant derived omegas into DHA. Either way, I wouldn't be without some kind of EFA supplementation for Omega 3s because I've never really stuck to a diet rich in them so it's a must for me. 3. Also, I take Iodoral, the iodine supplement which I get from LEF.org although I think it's available in other places, I find LEF to be as trustworthy as my own company and have no hesitation about recommending them. I have no financial affiliation to LEF but my company doesn't tend to do single nutrients so much as great formulas and frankly, I believe iodine should be taken in MILLIGRAMS instead of the microgram range which naturally occurs in our products. I've suggested a few times that we carry a similar product but apparently they don't feel as strongly as I do about it. From my own personal research, I agree with Dr. Sylver that most people are deficient in iodine and I even think much of the world is suffering from an iodine deficiency crisis. So for me, it's definitely a must-have. It's hard to be a researcher and watch people's willingness to wear pink ribbons and even email pink ribbon pictures to each other when their effort would be better spent informing people about iodine deficiency breast and ovarian disease. This link should go directly to the Iodoral: LEF Search - Welcome To The Life Extension Foundation Buyers Club Inc Those are my main three. I take a lot of other supplementation but those are always in my rotation while I'm mixing around everything else. My favorite multiple vitamin/mineral, an extra iodine source for an optimal amount and some kind of CLEAN tested EFA supplement with fish oil. Be careful what you buy, not everybody does the stringent testing you need to ensure you're not getting loaded with mercury and other dangerous substances. Although they're not supplements, I'd like to add as my four and five that I wouldn't ever go without some kind of RO water filter and my QE pendant from ewater.com [also not affiliated with them financially just so you know]. That pendant has made as big a difference in my life as even my ultimate classic and other supplements have. Sauna and shower are really the only time I take it off.
