Chlorella
Chlorella (Chlorella vulgaris)
A green freshwater algae known for detoxification support, heavy metal binding, and comprehensive nutritional profile.
Chlorella is a single-celled green freshwater algae that has gained popularity for its detoxification properties and nutritional density. It contains chlorophyll (the highest of any known plant), protein, vitamins, minerals, and a unique compound called Chlorella Growth Factor (CGF). It's particularly noted for its ability to bind heavy metals and support their elimination from the body, making it popular for detox protocols.
Mechanisms of Action
Heavy Metal Binding
Binds to heavy metals for elimination
High Chlorophyll
Highest chlorophyll content of any plant
Chlorella Growth Factor
Unique nucleotide-peptide complex
Recommended Dose
3-10g daily
Loading: Start with 1g and increase slowly to minimize detox symptoms
Optimal Timing
- Before meals for detox
- With food if GI sensitive
- Away from medications (may bind)
Take with food
Best Form
Broken cell wall chlorella powder or tablets
Alternatives: Whole cell chlorella (harder to digest), Capsules
Cell wall must be broken for digestibility. Powder works well in smoothies. Tablets are convenient but may be less fresh.
Duration
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: For heavy metal detox, take away from supplements containing minerals. 'Broken cell wall' chlorella is better absorbed.

βConclusions: Further randomised trials are needed to better assess the potential of these supplements as adjuvants for the control of cardiovascular risk factors.β
Key Findings:
- On the other hand, Spirulina intake led to a significant reduction in diastolic BP (-0.42, 95% CI: -0.81 to -0.02, p = 0.04) but did not significantly affect lipemia indexes, despite a trend toward a reduction in total cholesterol (-0.17, 95% CI: -0.39 to 0.06, p = 0.15).
- This meta-analysis suggests Spirulina supplementation can be used as an adjuvant to control cardiometabolic risk factors, particularly for BP.
- However, the magnitude of this effect is small and of uncertain clinical significance.
- Conclusions: Further randomised trials are needed to better assess the potential of these supplements as adjuvants for the control of cardiovascular risk factors.

Key Findings:
- We identified 227 herbal supplements with immunostimulatory properties, of which 15 were most strongly supported by the evidence.
- This article may serve as a reference to help clinicians counsel patients with autoimmune skin diseases on the risks associated with use of specific herbal supplements.
- Further research warranted to confirm findings

βTherefore, there is insufficient evidence to recommend any one particular nutritional intervention for the management of fibromyalgia and further research is needed.β
Key Findings:
- It is estimated to have a worldwide prevalence of 1.78%, with a predominance in females.
- Significant improvements in reported pain were observed for those following a vegan diet, as well as with the low fermentable oligo di-mono-saccharides and polyols (FODMAP) diets.
- Supplementation with Chlorella green algae, coenzyme Q10, acetyl-l-carnitine or a combination of vitamin C and E significantly improved measures of pain.

βThe results indicated that Chlorella supplementation improved levels of TC, LDL-C, SBP, DBP, and FBG but the changes in TG, HDL-C, and BMI were not satisfactory.β
Key Findings:
- Subgroup analyses based on intervention duration and Chlorella doses revealed that administration of Chlorella for 8 weeks or higher and doses higher than 4Β g/day significantly reduced TC, LDL-C, SBP, and DBP levels in the participants.
- Moreover, Chlorella supplementation significantly reduced TC and LDL-C levels in unhealthy individuals, and also reduced SBP and DBP in hypertensive ones.
- The results indicated that Chlorella supplementation improved levels of TC, LDL-C, SBP, DBP, and FBG but the changes in TG, HDL-C, and BMI were not satisfactory.
- More precise RCTs on subjects with different health status is recommended to clarify the effect of Chlorella supplementation on cardiovascular risk factors.
