Nope, it posts the answers to the survey to:

which responds:

"Hello from Lambda"

At which point it shows me my "recommended" packages which are supposedly "tailored to my body". Picking one of those sends me to a payment screen.

This isn't shady or false advertising. This is an out and out scam.

This is pretty mindblowing for a YC company, pretty damaging to their brand as well being associated with this type of snake-oil product.

Reminds me of the days when facebook peddled vitamins on their site when no one else was willing to do business with them. Not the best PR for YC or the company. I would imagine the thread gets nuked.

We definitely notice this feature is lacking in the customer flow. We have a dosage generator in our backend that our customer received but we will push that feature to be more transparent in our metabolic assessment.

Thanks treis. We currently do this offline in our lab, and it's not viewable directly online after the questionnaire just yet. Our customers have been informed of their specific dosage customization and given us feedback that it might be nice to see it online too (though this wasn't the highest need for them). For your specific question - we can't look up your submission data without an identifiable email address you've signed with, but baselining only with the height and weight provided, the 195lb man should be taking 3900 IU of Vitamin D3 vs. 1,000,000 IU of vitamin D3 for the 50,000lb woman, for example. We tailor the dosages across the other vitamins, minerals, and supplements as well.

By the way, I certainly hope that you are aware that there is a maximum safe dosage of vitamin D:

Children age 9 years and older, adults, and pregnant and breast-feeding women who take more than 4,000 IU a day of vitamin D might experience

Nausea Vomiting Poor appetite Constipation Weakness Weight loss Confusion Disorientation Heart rhythm problems Kidney damage

Recommending 3900 IU for a 195 lb man is alarmingly close to the level that can cause kidney damage and heart issues. If your model spits out 1,000,000 for a 50,000 lb woman, it probably will go over 4,000 given the right parameters.

Hi treis, we're working with one of the world's experts on Vitamin D and using clinical research based on studies conducted on populations over four decades. See one of his publications specifically looking at breast-feeding women and safe <4000 IU figures. http://pediatrics.aappublications.org/content/early/2015/09/...

Regarding the 1,000,000 Vitamin D response: typically our human customers are not 50,000lbs (a blue whale is typically 40,000lbs). However, it's probably not that unforeseeable if a blue whale has higher requirements for Vitamin D than an average human that's 195lbs. To your point though, we are careful that we do not go grossly over Recommended Daily Allowances, and our formulations reflect clinical research.

Is changing dosage based on body size the only customization you are doing?

No it is not, but that's why I mentioned based on the limited data and not being able to match back with all of your information we can only provide a rough estimation. With your entire metabolic assessment and your genetics information we determine more about your metabolic inefficiencies and whether you need a particular isoform of vitamin, for example.

Not sure where you got that feature since that feature is not yet available online. We can generate a list of dosages that customized base on your body composition.

I click on the big "START NOW" button under the text that says "Optimized formulations tailored to your body composition that’s 10X more effective." That process ends up with "recommended" packages I can purchase.

Thanks! When customers receive their package, they are informed of their dosages across the supplements. We've been getting requests to include an online feature of your supplement dosages being viewed - and are trying to get it out directly on our site ASAP.
