Supplements

Notes on various supplements. Also see the nutrition page.

Traditional supplements

These are "supplements" that have been around for a long time and so can be deemed safe. Note that, traditionally, there has been no real distinction between supplements and food as medicine. A good diet should already provide most necessary minerals, vitamins, amino acids and so on.

Synthetic supplements

Lab-made supplements. The ones listed are probably safe, but proceed with caution.

Magnesium

One of the most important minerals to supplement.

Vitamin C

Avoid – see here. Instead, get vitamin C from fruit and liver, not as ascorbic acid or citric acid.

Vitamin D

Avoid – supplementation increases calcium, depletes magnesium, potassium and retinol. Instead, get vitamin D from sunlight and seafood, eggs and cod liver (oil).

Omega-3

Avoid - capsules / fish oil easily turns rancid. Instead, get omega-3 (DHA/EPA) from seafood and bivalves, preferably wild caught.

Zinc

Avoid – can create copper/iron imbalance. Instead, get zinc from red meat and bivalves.

Iron

Avoid - all supplements and plant sources of iron have low bioavailability, and thus accumulates in your blood to a greater extent than heme iron. Get your iron from meat instead. Also see the section about iron in the modern dangers page.
