Well it's a blend of various things that are good (spinach, vitamin D3), things that are awful (rice bran, barley grass) and things that are likely going to do nothing at all. The main thing about this product though, is that almost all the ingredients are in insufficiently large quantities to do anything at all. 10% of a gram of spinach powder or mango 25% of a gram of apple powder are both clearly not going to do any good or any harm. One suspects that drying and powdering these plants does more to reduce their nutrients than it does concentrate them anyway. You'd do far better to just eat a plate of vegetables.

I'd tend to go by the paleo logic that avoiding harmful neolithic agents is more important than making sure you get even the most wonderful paleo foodstuff. Very small quantities of a food can be useful if you can specifically extract something that we benefit from in only very small quantities- though one would expect there to be quite few of these compounds outside of the range of vitamins and minerals- but there's no guarantee that the powdered extracts of the various foodstuffs above are actually isolating useful compounds.

I think most supplements are completely unnecessary on a true paleo diet that includes organ meats. Organ meats are the most nutrient dense foods on the planet, and a serving of liver blows away any supplement available in terms of nutrient content and assimilability.

There are three supplements I sometimes recommend in specific situations:

1. Vitamin D: may be necessary for those who live in northern latitudes, especially during the winter months. Low vitamin D is associated with so many diseases that it’s probably a good idea to keep levels up. The first choice would be to do this by eating seafood, but that’s not always practical or desirable for a number of reasons. Cod liver oil is my second choice for maintaining D levels. But note that this is more of a whole food than it is a supplement. In some cases when people are very deficient, i.e. under 25 ng/ml, I may suggest adding a D3 supplement in addition to the cod liver oil.

2. Fish oil has been shown to provide great benefit for cardiovascular disease and other inflammatory conditions. My preference here is that people reduce their intake of omega-6 fats and simply eat cold-water, oily fish a couple times a week to meet their omega-3 needs. Unfortunately, people have been scared away (unnecessarily, which is a topic for a future post) from eating fish, or perhaps it’s difficult for them to find or afford wild fish on a regular basis. In this situation I may recommend a fish oil. My favorites are whole-food based oils such as Green Pasture’s Fermented Cod Liver Oil and Vital Choice Wild Salmon Oil.

3. Magnesium is one of the most crucial nutrients in our diet, and many people are deficient. It protects against nearly every modern disease, and can be therapeutic for difficult to treat inflammatory conditions such as fibromyalgia, irritable bowel syndrome, arthritis, etc. Seaweed and various nuts and seeds are high in magnesium, but occasionally supplementation may be useful. I suggest using a highly-absorbable form such as magnesium glycinate.

4. Vitamin K2 has recently been revealed as an important nutrient in protecting against heart disease. It does this by telling the body to put calcium in the bones and teeth where it belongs, and not in the arteries and soft tissue. K2 is found in the fat of grass-fed animals and certain fermented foods like natto and hard cheese. I recognize that not everyone eats these foods for various reasons, so if someone has heart disease or is at risk for it I may recommend either Fermented Cod Liver / Butter Oil from Green Pastures, and/or an MK-4 supplement.

But even in these cases, I only suggest that people take these if they need them, and if they can’t (or won’t) get the nutrients from foods.

You can tap in a days food intake (every last scrap of fat, ounce of cream etc) and see what nutrients, if any, you are low on.

That list you've given looks awfully like overkill to me!

I have taken far far less supps since going Paleo and feel soooo much better. The only supps I take are Vit-D ( more in winter ) Coenzyme Q10 ( may cut back), some C and thats about it. Real food, real results. You are what YOU EAT, not swallow.

I drink a green drink about once a week. It's an added layer of protection I can afford. After drinking it, I feel great. It does a great job boosting my energy. I'll use it everyday when I'm ditching caffeine for the new year. Is it necessary? No. Does it help? Probably.

Drink the green powder, it wont hurt you. Eating neolithic food is something that is unavoidable, including carrots, cabbage, brocoli, cauliflower, etc. Just eat good whole foods, preferably organic, and grass fed meats. Too much dogma is not a good thing when it comes to successfully assimilating to a lifestyle. Just eat really clean, remove the grains, sugars, artifical ingredients, soy, beans, etc. A little supplementation is good, but stick with the basics and you will be good. Paleo is probably not a good name for this lifestyle, its more an attitude of eating only whole nutrious foods that do the least damage to our bodies.
