Heavy metals in NutriBiotic Ascorbic Acid With Bioflavonoids Powder
I obtained a certificate of analysis from NutriBiotic on the NutriBiotic Ascorbic Acid With Bioflavonoids Powder.
Caveat 1: the COA does NOT distinguish between organic/inorganic arsenic, methyl mercury vs elemental, ditto for forms of cadmium and lead. Thus there may be a risk here, or not.
Caveat 2: Vitamin C might act as a chelating agent that prevents absorption of hevy metals and/or helps the body excrete heavy metals.
All natural products have heavy metals that come from the soil the plants are grown in. No matter how good the food, organic is irrelevant. For example, your kale salad might have a high load of heavy metals.
Thus in now way am I commenting on the “quality” of this product—other products that include plant-based material will present similar issues, and might be better or worse, or much worse. This is why you should always seek out the certificate of analysis, which most vendors will not even supply.
I cannot be sure, but the heavy metals likely come from the lemon bioflavonids, all of which are concentrated into a powder.
Calculation at high daily dosing
Dosing at 20 grams a day is a very large amount of Vitamin C. However, I have good reason to try. Starting at day two, my energy level has increased substantially and my sleep needs have decreased by ~2 hours per night. Coincidence cannot be ruled out, but I intended to continue this experiment for a month in total or so, before backing off.
I have no way to know if these heavy metals will be absorbed and be a problem, so the only smart move is to cut back on this product while I seek-out a product with low levels of heavy metals, at least 10X lower and ideally 100X lower.
For reference, it being unclear what forms these figures relate to:
- Lead (Pb): maximum daily intake of lead (Pb) is no more than 12.5 mcg.
- Cadmium (Cd): ATSDR limit is 0.1 mcg per day per kg of body weight eg 7.7 mcg for 77 kg body.
- Mercury (Cd): 0.1 mcg per day per kg of body weight eg 7.7 mcg for 77kg body.
- Arsenic (As), inorganic: 0.1 mcg per day per kg of body weight eg 7.7 mcg for 77kg body.
Thus for a 20g dosing is over half the max daily Pb, ~3X max daily cadmium, ~3X max daily cadmium.
Arsenic at 20g dosing is ~3X daily arsenic but gets tricky: organic arsenic (tied to carbon atoms) is supposed to pass through the body quickly, but not inorganic arsenic. BTW, rice tends to be very high in arsenic.
|mcg per gram (ppm)||mcg for 20g serving||mcg for 40g dosing|
|Lead (Pb)||< 0.2||4 mcg||8 mcg|
|Mercury (Hg)||< 0.1||2 mcg||4 mcg|
|Cadmium (Cd)||< 1.0 ppm||20 mcg||40 mcg|
|Arsenic (As)||< 1.0 ppm||20 mcg||40 mcg|
