I like Huel. There are some changes, well improvements I would like to see though.
Phytonutrients - more of them. There are loads, but only a couple in Huel. Even a standalone phytomix would be ok being optional to add to Huel.
B12: Increased to somewhere along 500-1000% of RDI. Many people are deficient and higher doses pose no toxic risk.
D: Increased to 800-1500% of RDI. Huel is sold in UK/Europe/USA only IIRC. Most people in those areas get nowhere enough vit D. Upper Tolerable Limit is very high, this means no toxic risk but highly beneficial for many people.
Sodium: Increased. If possible, in regards to taste. Some people get headaches on Huel, often solved by adding some salt. Salt is so low in Huel that I see no harm adding a tiny bit more, if taste isnt affected.
About other vitamins/minerals I am not sure enough to comment on them individually but, I reckon they should be reviewed to see if changed doses could be beneficial. I wouldn’t know. However I do know about B12 and D so I would like to see those in higher doses! Yes it’s easy to supplement, fine. But as it poses no threat to people, but benefit to many it’s a good idea. Also many people use Huel to get the nutrition instead of taking a milkshake + a multivitamin pill.
Make a ketogenic powder. Keto is great for many people (not everyone), not only for weight loss but more stable energy levels, improved mental stamina, diabetics, so on. I would love a product for those who wants that.
TLDR: additional phytos (possibly as standalone), more vit D+B12. Investigate if other vits/mins could be beneficial in higher doses. Slightly more salt if taste can handle it. Keto as a new product line.
