Nobody wants to hear this, but…

Zinc deficiency is the most universal mineral deficiency problem in the world's plant crops today.

If the zinc isn't in the soil...

It's not going to be in the plants we eat.

If the zinc isn't in the plants we feed to our meat animals...

It's not going to be in the meat either!

This all comes together to have a massively negative impact on our health.

Zinc is necessary, as in essential, for immune health, liver function, skin health, and much more.

Because of these facts, zinc supplements have been a part of my client recommendations since I first went into practice.

Modern food doesn't have the zinc we need in it...

Toxins present in the body, like heavy metals, often require zinc to protect the tissues against them...

Putting the body into "detox mode" will increase the needs for zinc dramatically...

Supplements can help replenish zinc in the body, but not all types of zinc out there are effective...

If people are already deficient in zinc, already toxic, and then trying to go into "detox mode", they're way behind already!

If they can't get it from their zinc-deficient foods, yet they won't supplement, they'll never catch up and won't ever get to feel their best!

To make up for the difference, I’ve been using a specific form of zinc for over a decade to fill in this gap in the food supply.

Over the years, I also noticed that many people had wildly different needs for, and tolerances of, zinc supplements.

I needed to figure out a way to maximize the customizability of dosing, while minimizing the negatives of the zinc supplements I had previously been using...

I also needed to make it a liquid, so that children and those who can't swallow pills would be able get this life-changing mineral too...

And that’s when Nutrition Detective Liquid Zinc was born!

Here's what makes Nutrition Detective Liquid Zinc different:

We use the most bioavailable and effective form of zinc on the market today, zinc picolinate.

There are NO fillers, additives, binders, or any other junk found in today’s supplements! Just zinc picolinate and pure water.

We've maximized the adjustability of dosing by making one drop equal to 2 mg of elemental zinc.

Our bottle is the largest liquid zinc picolinate available, at 2 fluid ounces.

There's 2400 mg of elemental zinc in the bottle, equivalent to 80 30mg capsules, which means it is very economical.

In other words, this formula is the safest, purest form of bioavailable zinc you can get on the market today!

Make Nutrition Detective Liquid Zinc your choice for this critical mineral!


“After 10 years of neuropathy following a right thyroidectomy, the hair testing program and supplements from Dr. Smith are the only thing that has taken it away. I have spent the last decade trying countless medical, natural and homeopathic remedies, along with acupuncture, chiropractic, yoga and other avenues, without success. I am so pleased to finally be free of this pain.”

"Hi Garrett Thought I would share this with you. Yesterday I had coffee with a friend who I hadn’t seen for about 3 months and she said whatever I was doing, to keep doing it!!! She said my skin looked amazing and that you would never know that I had kids as old as they are (I was 29 when I had my first one, so not as if I was a teenager!!). So, not only must I look better, after going gluten free and not having digestive issues anymore, I feel better 🙂 Can’t thank you enough 🙂"

"Dr Smith’s lactoferrin is quite amazing. There’s a reason studies are claiming it to be a miracle protein. My liver function has been way up since I began using it, and I have always had bowel issues throughout my life. It’s very strong, so I can only do a little at a time, but that also means every little bit counts that much more. I’ve never been so regular!"

"I purchased a 90 count supply of lactoferrin earlier this year. I started slow and worked my way up to one capsule per day after 2 weeks. It really seemed to fix my gas/gut issues and helped me to become more regular. I could really tell it was causing an increase in bile being excreted the right way instead of the bile backing up into my blood. I plan to order more soon."

"Just wanted to update on LF. A week ago I went up from half a 1/64 twice a day to a full 1/32 twice a day. The catarrh and swollen lymph nodes are gone and I just feel great. Totally energized, full of life and sleeping amazingly well. Another thing I noticed - I have had glossitis for several years. I realized recently that the bald patches were predominantly on the sides of my tongue which according to the Chinese tongue map corresponds to the liver. Well yesterday I noticed, it has healed! I think it is the LF, as I still had it the first few months of doing this diet, so it seems like a recent change."

“Keystone minerals is the perfect gateway drug into Dr. Smith's work! My brother is very skeptical of how I eat and still falls into our old habits of how we were raised. While visiting him, I gave him a spare bottle of the Keystone Minerals and his attitude completely changed within the next couple of days. He has been depressed and anxious and as a result very moody. These helped him almost instantly and every time I talk to him on the phone now he sounds very energetic and so happy! It even has him curious about more of what I've implemented.”
