Who is it for?
Vegans and plant-based eaters — B12 occurs naturally only in animal products, making supplementation essential
Those with reduced gastric acid, suspected absorption issues, or gut health challenges
People taking metformin or proton pump inhibitors (known to deplete B12)
Heavy coffee and tea drinkers — caffeine and tannins can reduce B12 bioavailability from food
Anyone experiencing fatigue, cognitive fog, or mood changes that may be linked to B12 insufficiency

Frequently Asked Questions

Q: How is 4,000% RI safe? A: Vitamin B12 is water-soluble and any excess is excreted naturally. There is no established upper tolerable intake level for B12 — high doses are safe even with daily use.

I regularly buy this shampoo, but you know the flashy adverts often persuade you to try another. I unfortunately succumbed and now have a sore head, scalp to be precise! Just one wash and the itch stopped, now waiting for my lumpy head to become smooth again as before!
i have psoriasis on my scalp. i had been finding my current shampoo was not working as well as it had. I changed to this and am very happy with the results. I can have 3 itch free days in a row! do leave the shampoo on for the amount of time specified/
Only ordered the shampoo to see how it went. My son started getting a really bad dry flaky scalp. We tried several shampoos to no avail. This one, so far seems to work and his scalf looks healthier and is no longer dry and flaky.
This is a great everyday shampoo for psoriasis. The prescription ones are amazing but do nothing for the condition of your hair. This is settling on the skin and hair feels great.
