TruServ® (whole-food fruit & vegetable servings — FutureCeuticals)

Evidence Level
Preliminary
3 Clinical Trials
4 Documented Benefits
1/5 Evidence Score

TruServ is a line of whole-food fruit, vegetable, and leafy-green powders and pieces from FutureCeuticals and Van Drunen Farms, offered in organic and conventional forms. Rather than an isolated extract, it delivers dehydrated whole produce (for example apple, cranberry, and blueberry fruit blends, or kale, spinach, and broccoli greens blends) that a brand can label as USDA MyPlate-equivalent servings of fruit or vegetables. The idea is to help close the everyday produce gap, adding plant fiber, naturally occurring vitamins, and antioxidant phytonutrients to beverages, bars, and capsules. It is a nutrition-gap and antioxidant ingredient, not a therapeutic one, and it carries no finished-product clinical trials.

Studied Dose No established finished-product dose; sold to deliver label-defined USDA fruit/vegetable serving equivalents
Active Compound Dehydrated whole fruit/vegetable/greens powders; naturally occurring polyphenols, carotenoids, vitamins, and fiber (not standardized to a single actor)

Benefits

Helps bridge the produce gap

Most people fall short of USDA fruit and vegetable targets. TruServ whole-food powders let a finished product carry a defensible serving-equivalent claim, supporting overall diet quality by adding real fruit and vegetable material to everyday foods, drinks, and supplements.

Supported by Trial 1, Trial 3

Supplies antioxidant phytonutrients

Whole fruits, berries, and dark greens naturally contain polyphenols, anthocyanins, and carotenoids. Diets richer in these plant compounds help support the body's normal antioxidant defenses against everyday oxidative stress, though effects depend on the specific blend and amount used.

Supported by Trial 1

Adds naturally occurring vitamins and fiber

Because it is dehydrated whole produce rather than an isolate, TruServ contributes dietary fiber and food-form micronutrients such as folate and provitamin-A carotenoids, which support general nutritional adequacy as part of a varied diet.

Supported by Trial 1, Trial 3

Supports immune and general wellness nutrition

A produce-rich eating pattern is broadly associated with better wellness. Adding whole fruit and vegetable powders helps maintain the everyday nutrient foundation the immune system relies on, as part of an overall varied, plant-forward diet.

Supported by Trial 3, Trial 1

Mechanism of action

1

Whole-food phytonutrient delivery

Gentle dehydration of whole fruits, berries, and greens retains a native matrix of polyphenols, anthocyanins, flavonols, and carotenoids alongside fiber, delivering these compounds in food form rather than as purified isolates.

2

Antioxidant and redox support

Dietary polyphenols and carotenoids can scavenge reactive oxygen species and, more importantly, modulate endogenous antioxidant pathways (such as Nrf2-linked responses), helping maintain normal redox balance under everyday oxidative load.

3

Micronutrient and fiber contribution

Food-form folate, vitamin C, provitamin-A carotenoids, and soluble/insoluble fiber contribute to one-carbon metabolism, normal antioxidant vitamin status, and gut transit, mirroring effects seen when overall fruit and vegetable intake rises.

Clinical trials

1
Mixed fruit and vegetable concentrate raises antioxidant vitamins and lowers homocysteine

Randomized double-blind crossover trial (Samman et al., 2003, Journal of Nutrition). Component/class evidence on an encapsulated mixed fruit/vegetable concentrate, NOT the finished TruServ product.

Healthy adult men

Compared with placebo, the concentrate significantly raised plasma antioxidant vitamins and folate and lowered plasma homocysteine, suggesting whole-produce concentrates can improve markers of micronutrient status. Small study on a different branded concentrate.

2
Juice powder concentrate with exercise improves oxidation, inflammation, and microcirculation

Randomized double-blind placebo-controlled trial (Lamprecht et al., 2013, British Journal of Nutrition). Class evidence on an encapsulated fruit/berry/vegetable juice powder, NOT TruServ.

42 obese pre-menopausal women over 8 weeks

Supplementation plus exercise reduced markers of oxidation and inflammation and improved skin microcirculation versus placebo. Open to publication and product-specific caveats; results may not transfer directly to TruServ blends.

3
Fruit and vegetable intake and long-term health outcomes

Systematic review and dose-response meta-analysis of prospective cohorts (Aune et al., 2017, International Journal of Epidemiology). Dietary-pattern/epidemiological evidence supporting the produce-gap rationale, NOT a TruServ trial.

Pooled prospective cohort populations (millions of participant-years)

Higher fruit and vegetable intake was associated with lower risk of cardiovascular disease, cancer, and all-cause mortality. This supports the general value of closing the produce gap but does not test any specific powdered ingredient.

Side effects and drug interactions

Common Potential side effects

Generally well tolerated as a food-form ingredient; some people notice mild bloating or gas from the added fiber
Loose stools possible if intake of the powder is high
Possible allergic reaction in anyone sensitive to a specific fruit, berry, or vegetable in the blend
Natural pigments (for example from beet or berries) can temporarily color stool or urine

Important Drug interactions

Warfarin and other vitamin-K-antagonist blood thinners: greens blends (kale, spinach, broccoli) contain vitamin K that can affect INR; keep intake consistent and tell your doctor before starting.
Because blends vary in composition, if you take any prescription medication or have a medical condition, tell your doctor or pharmacist before adding a concentrated produce powder.
People with kidney stones or on potassium-restricted or oxalate-restricted diets should check with their clinician, since some vegetable and greens blends are higher in oxalate and potassium.
