Research-based supplement kits
Each kit is a ready stack for one goal in our Fullscript store. It holds only the supplements graded A or B for that goal on this site and, where a product matches the studies, the dose the studies used.
A kit follows the evidence pages it is linked from: if a supplement's grade for the goal drops, it leaves the kit. Where nothing for a goal has strong human evidence, the stack says so and is labelled limited evidence. See how we grade for what the letters mean.

What is in it
Fullscript kitA research-based stack for nasal allergies: the supplements with the strongest human evidence, with the doses used in the studies where a product matches them.Open on FullscriptBefore you use it
Use only spirulina from a brand that tests for algal toxins (microcystins): contaminated blue-green algae has caused liver damage. Don't take spirulina with an autoimmune disease or phenylketonuria (it contains phenylalanine). Black seed can lower blood sugar and may slow blood clotting, so take care with diabetes medicines or blood thinners. Not in pregnancy or breastfeeding.

If you take blood pressure medicine, ask your prescriber first: both can add to its effect. An animal study suggests hibiscus may interact with some water pills (diuretics).

Get your ferritin and transferrin saturation tested first: guidelines suggest iron only if ferritin is 75 ng/mL or lower, or saturation is under 20%. Each capsule (65 mg iron) is above the 45 mg daily upper limit for adults, so take it only at the dose your clinician sets. Keep iron locked away from children: an overdose can kill a child.

The trials used zinc gluconate; this kit's zinc picolinate gives the same amount of zinc. Take it with food, as nausea and stomach upset are common. Taking zinc for months can lower copper, so don't take it longer than the trials did without your clinician. Keep zinc away from children. For adults; for a child or teenager, ask their doctor first.
Long-term high-dose zinc can cause copper deficiency. Avoid nasal zinc products (loss of smell).
