What to know about Immunocal Booster
Immunocal Booster is designed to sit alongside the core range rather than replace it, which is why the brand describes taking it with Immunocal rather than instead of it.
Its centerpiece is broccoli seed extract providing sulforaphane glucosinolate, a plant compound studied for its role in the Nrf2 pathway, which is involved in switching on the body’s own antioxidant defenses. That is a different mechanism from supplying an antioxidant directly.
Around it sits a reds and greens blend of organic fruits, vegetables, sprouts and greens, plus eleven vitamins and selenium. It contains no caffeine, so it suits any time of day.
To understand the pathway this formula targets, read how the Nrf2 pathway switches on your antioxidant defenses.

Common questions about Immunocal Booster
What is an Nrf2 activator?
Nrf2 is a signaling pathway the body uses to switch on its own antioxidant defenses. An Nrf2 activator aims to support that switch rather than supplying antioxidants directly. Immunocal Booster is built around one, which is what sets it apart from a standard antioxidant supplement.
Can you take it with Immunocal?
Yes, that is the intended use. It is formulated to be taken alongside Immunocal rather than instead of it: one supports glutathione production, the other supports the pathway that switches antioxidant defenses on.
Does it contain caffeine?
No. The original Immunocal Booster is caffeine-free. If you want natural caffeine, the Booster Energy Performance and Booster Performance Hibiscus versions contain it.
What vitamins and minerals are in it?
Vitamins A, C, E, K, B6 and B12, riboflavin, niacin, folate and pantothenic acid, plus 25 mcg of selenium. The full amounts are listed below.
What is sulforaphane glucosinolate?
It is the natural precursor of sulforaphane, a compound found in broccoli and broccoli sprouts. Immunocal Booster includes broccoli seed extract providing 6 mg of sulforaphane glucosinolate per stick.
Is Immunocal Booster the same as Booster Energy Performance?
No. The original Booster is a caffeine-free reds and greens stick with eleven vitamins. Booster Energy Performance contains 150 mg of natural caffeine with vitamins C and B12 and selenium.
Does Immunocal Booster contain allergens?
It contains sesame. Check the current label for full allergen information.
