8Greens Proprietary Blend

Also known as: Spinach, Kale, Aloe Vera, Wheatgrass, Blue-Green Algae, Barley Grass, Chlorella, Spirulina, 8Greens Proprietary Blend

Overview

8Greens is a proprietary blend of eight dehydrated green plant extracts and algae, formulated as effervescent tablets or gummies. It includes spinach, kale, aloe vera, wheatgrass, blue-green algae, barley grass, chlorella, and spirulina. Marketed to support overall health, boost energy, enhance immune function, and provide a convenient source of phytonutrients and vitamins, the blend contains a mix of antioxidant-rich greens and algae, supplemented with synthetic vitamins such as vitamin C and B12. The blend is designed to preserve phytonutrients by using dehydrated, non-heated extracts. While individual ingredients have been studied extensively, the proprietary blend as a whole lacks direct clinical trials. Evidence is primarily from studies on individual ingredients rather than the blend itself. No independent RCTs or meta-analyses specifically on 8Greens proprietary blend were found.

Benefits

Ingredients such as spirulina and chlorella have demonstrated antioxidant, anti-inflammatory, and immune-supportive effects in clinical studies, but these benefits depend on adequate dosing. Vitamin C and B vitamins included support energy metabolism and immune health. Algae like spirulina and blue-green algae may improve lipid profiles and reduce oxidative stress. Barley grass and wheatgrass have shown potential in reducing inflammation and improving antioxidant status. Benefits may be more pronounced in individuals with nutrient deficiencies or increased oxidative stress. Clinical benefits of individual ingredients often require doses higher than those likely present in 8Greens tablets; under-dosing is a concern. Effects from greens and algae supplements typically require consistent use over weeks to months.

How it works

8Greens works through several biological pathways. Its antioxidant activity comes from polyphenols and chlorophyll, which neutralize free radicals. It modulates the immune response and supports mitochondrial energy metabolism via B vitamins. The blend supports the immune system, reduces oxidative damage in cells, and may indirectly improve gut health. Antioxidants neutralize free radicals, and B vitamins act as cofactors in enzymatic energy pathways. Dehydrated extracts preserve phytonutrients; however, high single doses of vitamin C may be rapidly excreted; bioavailability depends on formulation.

Side effects

8Greens is generally safe for healthy adults, as it contains natural plant extracts and vitamins. Common side effects include potential mild gastrointestinal upset due to sorbitol and stevia leaf extract, and possible bladder irritation from high-dose vitamin C. Uncommon side effects include allergic reactions in sensitive individuals. Vitamin K in greens may interact with anticoagulants, so caution is advised. It is contraindicated for individuals with allergies to algae or specific greens, and those on blood thinners should consult healthcare providers. Pregnant or breastfeeding women should seek medical advice, and children’s safety has not been established.

Dosage

A minimum effective dose has not been established for the proprietary blend. Clinical studies on spirulina and chlorella suggest doses of 1-3 grams daily for effects, which is likely higher than the amount of greens per tablet, suggesting that 8Greens tablets may under-dose key ingredients. There is no specific maximum safe dose for the blend, but high doses of vitamin C (>2g/day) may cause side effects. Vitamin C and B vitamins may be better absorbed when taken with food, and spreading intake may improve absorption. Effervescent tablets allow rapid dissolution, and gummies are available but may contain sugars. Dehydrated extracts preserve nutrients, but synthetic vitamins may have different absorption profiles. A balanced diet supports absorption of vitamins and minerals.

FAQs

Is 8Greens a replacement for vegetables?

No; it is a supplement intended to complement, not replace, a healthy diet.

Are the doses of key ingredients sufficient?

Likely under-dosed for spirulina and other algae to produce significant clinical effects.

Is it safe to take daily?

Generally yes, but watch for gastrointestinal sensitivity.

Does it boost energy?

B vitamins support energy metabolism, but effects depend on baseline nutrient status.

Can it cause side effects?

Mild digestive upset possible due to sweeteners and vitamin C.
