Hi @jager5210, I ran the protocol supplements by my doctor who ran them by the Mayo pharmacist and he only commented on thinking the Omega 3 and 6 oils were high but didn't say much else. I'm no expert but everything I've read says B12 is generally safe at any dosage. It is always wise to run supplements by your doctor in case you have a condition that a high B12 dosage may have an adverse affect on you. The liquid B12 product hasn't been available for quite awhile now so I have been using a substitute - Seeking Health | Active B12 Lozenge with L-5 MTHF 1000 mcg tablet. It does have a warning for pregnant women and children.

I may be wrong but the Consumer Labs article seems to be written to a healthy person taking vitamins vs. a person who is using therapeutic level dosages to help with a condition. The one vitamin I really worry about is B6 because high levels of it are toxic and can cause neuropathy or make it worse. A lot of multivitamins have high levels of B6.

Here are a couple of links that provide more info:
