Colorectal Polyps

Colorectal polyps are growths on the lining of the colon or rectum. They are typically benign, but certain types (i.e., villous adenomas) can become cancerous.

Evidence-Based Protocol

Supplement stack ranked by research quality

Moderate Evidence

Primary Stack (Tier 1)

CalciumB
1000-1200mg daily with food

Binds bile acids and fatty acids in colon; reduces cell proliferation; studied for polyp recurrence prevention

15 studies | 3,000 participants
Vitamin DB
2000-4000 IU daily (maintain levels 40-60 ng/mL)

May enhance calcium's protective effects; anti-proliferative effects on colon cells; deficiency linked to increased risk

15 studies | 2,500 participants

Supporting Stack (Tier 2)

Fiber (Psyllium, Wheat Bran)B
25-35g total fiber daily from food and supplements

Increases stool bulk; reduces transit time; dilutes carcinogens; produces beneficial short-chain fatty acids

20 studies | 5,000 participants
Omega-3 Fatty AcidsB
2-4g EPA+DHA daily

Anti-inflammatory; may reduce COX-2 and prostaglandins in colon; studied for polyp prevention

10 studies | 800 participants
FolateC
400-800mcg methylfolate daily (from food preferred)

Supports DNA synthesis and repair; deficiency may increase colorectal cancer risk; complex relationship

12 studies | 1,000 participants
ProbioticsC
10-20 billion CFU daily (multi-strain)

Supports healthy gut microbiome; may produce protective short-chain fatty acids; emerging area

8 studies | 500 participants
CurcuminC
500-2000mg daily with enhanced absorption

Anti-inflammatory; laboratory studies show effects on colorectal cancer cells; limited human trial data

8 studies | 300 participants
Green Tea ExtractC
300-400mg EGCG daily

Polyphenols with anti-cancer properties; studied for colorectal adenoma prevention

6 studies | 400 participants
SeleniumC
100-200mcg daily

Antioxidant; some observational data suggest lower colorectal cancer risk with adequate selenium

6 studies | 400 participants

How It Works

Colorectal polyps are growths on the inner lining of the colon or rectum. While most polyps are benign, some types (adenomatous polyps or adenomas) can develop into colorectal cancer over time. Removing polyps during colonoscopy prevents cancer.

TYPES OF POLYPS:

•Adenomatous (adenomas): Can become cancerous; need removal and follow-up
•Hyperplastic: Usually not precancerous; small ones often left alone
•Sessile serrated: Precancerous; require careful surveillance
•Inflammatory: Related to IBD; not typically precancerous

SCREENING SAVES LIVES:

•Colonoscopy starting at age 45 (earlier if high risk)
•Removes polyps before they become cancer
•Follow surveillance intervals based on findings

LIFESTYLE FACTORS that reduce polyp risk:

•High-fiber diet (vegetables, fruits, whole grains)
•Limit red and processed meat
•Limit alcohol
•Maintain healthy weight
•Regular physical activity
•Don't smoke

MEDICATIONS sometimes used:

•Low-dose aspirin (discuss with doctor - bleeding risk)
•NSAIDs reduce polyp risk but have side effects

* Calcium with Vitamin D has the strongest evidence for reducing adenoma recurrence.

* Fiber supports healthy colon function and may reduce risk.

* Omega-3 Fatty Acids have anti-inflammatory effects that may help prevent polyps.

Expected timeline: Prevention is a long-term commitment. Studies showing benefit typically follow patients for 3-5 years. Regular colonoscopy surveillance is essential regardless of supplement use.

Type 2 Diabetes

1 shared supplement · 868 outcomes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.

Schizophrenia

1 shared supplement · 69 outcomes

Schizophrenia is a brain condition that may cause auditory and/or visual hallucinations, delusions, difficulties with emotions and cognition, and verbal communication problems. These symptoms manifest between the ages of 16 and 30.

Prediabetes

1 shared supplement · 144 outcomes

Prediabetes is the intermediate stage between healthy blood glucose levels and diabetes. It is associated with an increased risk of cardiovascular disease and type 2 diabetes. Weight loss induced by lifestyle intervention is the primary treatment and is very effective.

Polycystic Ovary Syndrome (PCOS)

1 shared supplement · 220 outcomes

Polycystic ovary syndrome (PCOS) is a hormone disorder that is common among women of reproductive age. PCOS is often caused by high androgen levels and frequently involves infertility, cysts on the ovaries, and metabolic abnormalities.
