The following list is from a Mercola article: “Are These the 19 Most Important Supplements to Take?” I’ve saved it as a pdf: Top20-SupplementsToTake-AndWhy_MCL_032423.pdf.

• Includes: 1. Story At-A-Glance; 2. Supplement List; 3. Cat’s Notes

Story At-A-Glance

• • “Molecular hydrogen is a selective antioxidant, meaning it doesn’t indiscriminately
    suppress free radicals but, rather, helps your body make the antioxidants it needs
    Glycine and NAC are glutathione precursors; your body uses glutathione to increase the effectiveness of antioxidants such as vitamin C, which is why it’s known as the “master antioxidant”
  • Magnesium is involved in the functioning of more than 300 enzymes, and many people are deficient
  • The best supplements for you depend on your age, health status, diet and health goals
    
  • I mention a bonus supplement at the end of the article“

Supplement List

Cat’s note: I’ve changed the order of the list, to be in alphabetic order, and to put all vitamins and all minerals together:

• Molecular hydrogen (H2)
• Minerals:
  1. Magnesium
  2. Copper
  3. Zinc
  4. [Cat’s note: he does not discuss the importance of taking proper Zinc-to-Copper ratio of 8:1; see links to articles about this ratio, below]
• Vitamins:
  1. Vitamin A (Retinol)
  2. Vitamin B complex
  3. Vitamin B-12; his important note: Be sure to choose the more biologically active and absorbable form: methylcobalamin, or “methyl B12.” Avoid using the most common form of B12, cyanocobalamin.
  4. Vitamin C (not ascorbic acid)
  5. Vitamin D [specifically D3]
  6. Vitamin E
  7. Vitamin K2
• NAD+ (nicotinamide adenine dinucleotide)

Cat’s Notes:

Zinc:Copper Ratio:  Here’s some articles about the importance of taking proper ratio

1. Livestrong: livestrong.com/article/511087-how-to-take-copper-with-zinc/ From article: Zinc and copper should be taken in a proper balance of “2 mg of copper …for every 15 mg of zinc [a zinc-to-copper ratio of 7.5:1] … but do not exceed the daily maximal intake limit of 45 mg of zinc per day.”
2. Weston A Price: westonaprice.org/health-topics/modern-diseases/copper-zinc-imbalance-unrecognized-consequence-of-plant-based-diets-and-a-contributor-to-chronic-fatigue/ From article by Laurie Warner, MA, CNC, the recommended zinc-to-copper ratio is 8:1
3. Dr Jockers: drjockers.com/copper-zinc-imbalance/ [has a long but interesting article about this]
