Solgar Earth Source Food Fermented Koji Zinc 30 Capsules is a zinc food supplement in vegetable capsule form, providing 25 mg of zinc per capsule. The zinc comes from a koji culture grown on cooked rice, so the capsule offers a food-fermented source of the mineral in a once-a-day dose.

Key Features

• 25 mg zinc per capsule: Each capsule provides 25 mg of zinc, which is 250% of the nutrient reference value (NRV).
• Koji-fermented zinc: The zinc is supplied as Koji Fermented Zinc (Ultimine), made by growing koji on cooked rice, which is enriched with zinc as it ferments.
• One capsule a day: The directions on the manufacturer's page give a dose of 1 capsule daily.
• Suitable for vegans and vegetarians: The manufacturer lists this product as suitable for both vegans and vegetarians.
• Authorised zinc claims: Zinc contributes to the normal function of the immune system and to the protection of cells from oxidative stress.

What does zinc contribute to?

Zinc contributes to normal immune system function, normal cognitive function, the maintenance of normal skin, nails and hair, the protection of cells from oxidative stress, and normal fertility and reproduction.

How much zinc is in one capsule, and is it too much?

One capsule contains 25 mg of zinc. The NHS advises not to take more than 25 mg of zinc supplements a day unless a doctor advises it, so this capsule provides the full amount of that advised limit on its own.

What is the difference between koji zinc and standard zinc supplements?

Koji zinc is made by fermenting a koji culture on cooked rice, which is enriched with zinc as it matures. Solgar describes the result as a food-based form of zinc, in place of a mineral zinc salt added directly to the capsule.

Take 1 capsule a day.

Please note the following:

• Do not take more than 25 mg of zinc supplements a day unless a doctor advises it. One capsule provides 25 mg of zinc, so do not take other zinc supplements alongside it without medical advice.
• Taking high doses of zinc reduces the amount of copper the body can absorb, which can lead to anaemia and weakening of the bones.
• Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
