MCAS-Friendly Electrolyte Drink (V1 — Superseded)
This version has been superseded by Recipe-v2.
See flaws noted at the bottom of this document and the MCAS Safety Report for full analysis.
Flavor Profile: Customizable per person (base is unflavored functional mix) Serving Size: ~4.625 tsp per 33 oz tumbler Batch Size: 48 servings (~9.5 days for household)
Base Mix — Per Serving (Everyone)
| Ingredient | Amount | Nutrient | Qty | % DV |
|---|---|---|---|---|
| Iodized table salt | 1/2 tsp | Sodium | ~1,180 mg | 51% |
| Potassium chloride | 1/2 tsp | Potassium | ~1,050 mg | 22% |
| Magnesium glycinate | 1/2 tsp | Magnesium | ~112 mg | 27% |
| Ascorbic acid | 1/2 tsp | Vitamin C (+ acid) | ~2,250 mg | 2,500% |
| Dextrose | 1.5 tsp | Glucose (SGLT1) | ~6 g | — |
| L-Theanine | 1/8 tsp | Calm focus | ~200 mg | — |
| Creatine monohydrate | 1 tsp | Energy + histamine metabolism | ~5 g | — |
| TOTAL | 4.625 tsp |
Sugar per serving: ~6.5 g (~13% DV). Dextrose is functional — drives SGLT1 sodium-glucose cotransport for better absorption.
Vitamin C note: 1/2 tsp provides both the acid profile (making it drinkable) and vitamin C. Plasma half-life is ~30 min to 2 hrs, so spaced tumblers are processed independently.
Creatine note: Supports histamine metabolism by aiding DAO and HNMT enzyme activity. Also conserves methylation capacity. Discuss with Xander’s pediatrician before including him — consider a separate batch without creatine for him.
Batch Mix — 48 Servings
| Ingredient | Per Serving | ×48 Batch |
|---|---|---|
| Iodized table salt | 1/2 tsp | 1/2 cup |
| Potassium chloride | 1/2 tsp | 1/2 cup |
| Magnesium glycinate | 1/2 tsp | 1/2 cup |
| Ascorbic acid | 1/2 tsp | 1/2 cup |
| Dextrose | 1.5 tsp | 1.5 cups |
| L-Theanine | 1/8 tsp | 2 tbsp |
| Creatine monohydrate | 1 tsp | 1 cup |
| TOTAL | 4.625 tsp | ~4.6 cups |
Household: 2/day for Chris & Sara, 1/day for Xander = 5/day. 48 servings ≈ 9–10 days.
Flavor Add-Ins (Per Person, At the Tumbler)
| Person | Flavor | Add-In | Notes |
|---|---|---|---|
| Chris | Moscow Mule | Lime powder + ginger powder (~1 tsp total) | See Flavor Blends |
| Chris | Mojito | Lime powder + mint powder (~1 tsp total) | See Flavor Blends |
| Sara | Salted Caramel | Maple syrup (1-2 tsp) | Low-salicylate, low-histamine |
| Xander | TBD | Any of the above | Based on preference |
Daily Add-In (Not in Powder Mix)
Totaria Liposomal Quercetin + Bromelain Drops — add 2ml to your first tumbler each morning.
Contains: Quercetin 1000mg (mast cell stabilizer), Bromelain 500mg, Vitamin D3 30mcg (156% DV), Vitamin K2 90mcg (156% DV), Zinc 10mg (75% DV), Elderberry 400mg, Resveratrol 200mg, Turmeric 100mg, Black Pepper 10mg, Vitamin C 30mg.
Covers Vitamin D, Zinc, and anti-inflammatory support. B12 is best taken as a separate sublingual tablet — dose is in micrograms, too small for powder mix.
Portioning (Vial System)
- Measure all dry ingredients into a large bowl using the cup/tbsp batch amounts
- Whisk thoroughly for 60 seconds (grind coarser ingredients first if needed)
- Transfer to large airtight jar (5+ cup capacity), shake well
- Fill 30ml amber glass vials — each gets ~4.625 tsp of base mix
- Daily: grab a vial, pour into 33 oz tumbler, add your flavor, fill with water, shake
- First tumbler of the day: add 2ml quercetin drops
Storage: Cool, dry place. Amber glass protects light-sensitive ascorbic acid and L-theanine.
V1 Flaws Identified (April 2026)
Issues found via MCAS safety audit. See MCAS Safety Report for full sourced analysis.
1. Iodized Salt — Mast Cell Trigger
Iodine-containing compounds activate mast cells via MRGPRX2 receptors, triggering Ca²⁺ influx and degranulation (2021, Biomedicine & Pharmacotherapy). The MCAS clinical community consistently recommends non-iodized salt. Swap to Redmond Real Salt, plain sea salt, or pink Himalayan.
2. Potassium Too High — Na:K Ratio Undermines POTS Goals
The 1:1 Na:K ratio is unusual for POTS. WHO ORS uses ~3.75:1. Excess potassium promotes renal sodium excretion via RAAS, partially undercutting the blood volume expansion that POTS patients need. Halve potassium to 1/4 tsp (~525mg) for a ~2:1 ratio.
3. Vitamin C Dose Too High Per Bolus
At 2,250mg in a single serving, absorption drops below 50% due to SVCT1 transporter saturation. Also increases oxalate load (associated with kidney stone risk in men per JAMA Internal Medicine 2013). Oxalates can paradoxically raise histamine. Halve to 1/4 tsp per serving; drink 2 servings/day for same daily total.
4. Elderberry in Quercetin Drops — Immune Stimulant
Elderberry upregulates TNF-α, IL-1β, IL-6, IL-8 (Barak et al. 2001). Problematic when the immune system is already dysregulated. Mast Cell 360 advises against daily elderberry for MCAS patients. Find a quercetin product without elderberry, or accept the trade-off.
5. Black Pepper/Piperine in Quercetin Drops — Gut Permeability + Drug Interaction
Piperine increases intestinal permeability for histamine. Combined with quercetin, it increases fexofenadine blood levels by 55–68% (Kim et al. 2009, European Journal of Clinical Pharmacology). Dangerous for patients on common MCAS antihistamines. Find a quercetin product without piperine. Use liposomal curcumin instead for absorption.
6. Fexofenadine Interaction Warning
Quercetin alone increases fexofenadine AUC by 55% and Cmax by 68% via P-glycoprotein inhibition. If taking fexofenadine (Allegra), either switch to cetirizine (Zyrtec) or separate dosing by 4–6 hours minimum. Cetirizine and famotidine have the lowest interaction risk with this formula.
7. Creatine-HNMT Claim — Plausible But Unproven
The methylation-sparing pathway is biochemically sound (creatine synthesis uses ~40–50% of SAMe methyl groups), but no direct human trials have measured histamine outcomes from creatine supplementation. The claim should be framed as mechanistically plausible, not clinically proven.
