THE SCIENCE BEHIND IT
Three of these five have an authorised claim. Two do not.
In the EU, only a short list of health claims is authorised. Chromium is on it for normal blood glucose, and vitamin B1 and magnesium for normal energy-yielding metabolism. Alpha-lipoic acid was turned down, and cinnamon, like most botanicals, has no authorised claim. None of the three claims says anything about prediabetes or about bringing a blood result back into range.
Chromium
AUTHORISED CLAIM
WHAT WE ARE ALLOWED TO SAY
“Chromium contributes to the maintenance of normal blood glucose levels.”
Regulation (EU) 432/2012, on a product that is at least a source of trivalent chromium, which means 15% of the NRV, or 6 µg. This formula carries 200 µg, 500% of the 40 µg NRV. EFSA has set no upper limit for chromium, for lack of data. The German BfR suggests no more than 60 µg in a supplement, and this formula is more than three times that: our file records the higher dose as a deliberate therapeutic choice, and our label warnings cap it at 250 µg a day. It is also the reason for the firmest rule here: not with type 1 diabetes, because chromium can strengthen the effect of insulin.

Alpha-lipoic acid
NO AUTHORISED CLAIM
WHAT WE ARE ALLOWED TO SAY
Nothing. EFSA looked at every claim submitted for it, blood glucose and insulin sensitivity included, and rejected them all.
It is here on trial work, not on a claim. The trial on file, SYDNEY 2, gave 600 mg a day for five weeks to 181 people with diabetic polyneuropathy. This formula carries 200 mg, a third of that, which our own file calls a preventive dose, below the one tested. 200 mg is also exactly the upper reference in our file for a supplement. That is a reason to include it, not a permission to promise anything.

Cinnamon
NO AUTHORISED CLAIM
WHAT WE ARE ALLOWED TO SAY
Nothing. No authorised claim, and we do not claim a health benefit for it.
The ingredient on file is Cinnamomum cassia, and cassia carries coumarin. EFSA sets a tolerable daily intake for coumarin of 0.1 mg per kg of body weight, about 6 mg for a 60 kg adult, which our file turns into roughly 1–2 g of cassia a day. This formula carries 1,000 mg. Our file prefers Ceylon cinnamon (Cinnamomum verum), which carries far less coumarin, and the species in this formula is flagged to be confirmed before it goes out. Until then, we would rather tell you than round it off.

Vitamin B1 (thiamine)
AUTHORISED CLAIM
WHAT WE ARE ALLOWED TO SAY
“Thiamine contributes to normal energy-yielding metabolism.”
Regulation (EU) 432/2012, on a product that is at least a source of thiamine. The form here is benfotiamine, the fat-soluble one, at 100 mg, the top of the 50–100 mg our file lists as its therapeutic range. The reference intake for thiamine itself is 1.1 mg. We have not yet documented the thiamine equivalent of benfotiamine, so we print no percentage and the claim's condition, at least a source of thiamine, is still to be confirmed on file. EFSA has set no upper limit for it.

Magnesium
AUTHORISED CLAIM
WHAT WE ARE ALLOWED TO SAY
“Magnesium contributes to normal energy-yielding metabolism.”
Regulation (EU) 432/2012, on a product that is at least a source of magnesium, which means 15% of the NRV per dose. 200 mg is 53%. It is the claim this formula is filed under. 200 mg also leaves only 50 mg of room under the 250 mg upper limit for supplemental magnesium, which is why this formula cannot share a day with any other VION formula that carries it.
