Glucose control is only one aspect of a diet, and it is possible to find ways of keeping low blood sugars but using techniques that may be harmful to some, or with long term use. I want to raise some awareness of known or potential deficiencies in a non animal diet where those nutrients are otherwise naturally provided in meat or dairy products, As an omnivore considering using less animal food sources in the future, I am trying to prepare myself with whatever mitigation may become necessary.
I want to consider each nutrient in turn so we do not get bogged down in generalities. I am not interested in which brand is best, or where these are sourced or even what the brand name or supplier might be, So please do not discuss this since it is largely irrelevant to my OP.

The first one is Vitamin B12 (already discussed previously)
Essential nutrient that is not made or synthesised by our bodies.
Water soluble vitamin that gets stored in the liver.
Some say it can be absorbed from unwashed plants grown in soil used by livestock or dairy since it is from a microbe that grows in those conditions. However it does imply ingesting animal product,
Can be synthesised from algal solution by a high energy high water demand month long process so is expensive but vegan.
supplements are readily available from multiple sources.
Requires Folate to be present
Benefits from Vitamin C
High intake of seaweed, folate or Vitamin B6 (pyridoxine) can cause false highs in the blood tests.
Overdose may give nasty side effects but is not considered dangerous. excreted in urine.
Cereal and grain products sold in UK are required to be fortified with B12 by law.
in the absence of animal products in the diet, then supplementation or using fortified food products is Essential
Yeast extract is only useful if properly fortified.
Plant based meat alternatives may contain added B12 but not required by law.
There s a source used by vegetarians called spirulina, but the ingredient in it is a pseudovitamin and is biovalent = inactive. Don't waste your money on it.
Many vegan friendly B12 supps are derived from seaweed. Be aware that the weed is often dried first, and this destroys the B12 active ingredient.
Like many supplements, the active ingrdients need to make it to the small intestine, but the acid environment in the stomach can damage or degrade the vitamins. For B12 this may be why GP's offer injections rather than orals. Vitamin C is also degraded in the stomach, (or in the glass if in a smoothie)
