43 out of 100

C4 Ultimate Shred Lemon Italian Ice combines vitamins, amino acids and a proprietary blend, whose undisclosed contents make the complete formula harder to judge.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality31

Niacin is clearly identified as niacinamide, helping with form comparison. Many other preparations remain unspecified, limiting reliable comparison of the full formula.

Ingredient Transparency57

Amounts are stated for the named ingredients, but many preparations are unspecified. The proprietary blend does not identify its individual contents, leaving part of the serving unclear.

Value For Money38

The niacin content is relatively expensive for the product cost. Many other ingredients cannot be judged reliably for value.

Customer Satisfaction74

A modest number of customers give strongly positive feedback. That limited feedback base does not establish the formula’s effectiveness or safety.

Product Focus28

The formula combines many ingredients, adding complexity. The undisclosed blend prevents a complete understanding of the active ingredients and their purpose.

82 Performance

Sustained-Release Niacin with niaXtend 500 mg

Doctor's Best
Sustained-release nicotinic acid provides a clearly named form and controlled delivery, though the high amount still carries liver-related risk and needs safety guidance. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
82 Performance

No Flush Niacin (Inositol Hexanicotinate) 800 mg

Life Extension
Clearly named inositol hexanicotinate supports comfort-focused niacin use with less flushing, but its cardiovascular effects may be less direct than nicotinic acid. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
80 Performance

Niacinamide

Thorne
Niacinamide offers a clearly identified non-flushing form suited to NAD metabolism and skin-related use, although the amount is high for routine nutrition. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
85 Budget

Niacin 100 mg

Source Naturals
Clearly identified niacinamide provides a moderate, economical vitamin B3 serving with little classic flushing risk. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
80 Budget

Super Vitamin B-Complex

Spring Valley
Broad measured B-vitamin coverage offers strong value, though unspecified chemical forms and unnecessarily high thiamine limit refinement. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
81 Budget

B-Complex with Folic Acid plus Vitamin C

Nature's Bounty
A broad B-complex with vitamin C provides low-cost daily coverage, while conventional forms and duplicated thiamine entries reduce form quality. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
82 Value

Niacin 100 mg

Nature's Way
Clearly identified immediate-release nicotinic acid provides a modest and inexpensive niacin serving, but temporary flushing remains likely. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
80 Value

Niacinamide 500 mg

21st Century
A simple non-flushing niacinamide formula offers strong serving value, though the amount is well above basic nutritional needs. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
80 Value

No-Flush Niacin (Inositol Hexanicotinate) 500 mg

Solgar
Inositol hexanicotinate provides clearly named no-flush niacin exposure with practical value, while its effects may be less direct than nicotinic acid. It cannot replace citrulline, beta-alanine, betaine, taurine, or Nitrosigine, but it avoids the original hidden thermogenic matrix.
