Analysis

Bovine collagen peptides at 13 g provide the formula’s strongest structural ingredient. Ceramides and black- and red-currant extracts broaden the focus toward skin hydration and antioxidant support.

Nicotinamide riboside adds a cellular-energy component, while the 50 mg betaine amount is too small for focused use. The stated 12 mg protein value conflicts with 13 g of collagen peptides and should be clarified.

The powder is better aligned with a beauty or collagen routine than with weight gain. A modest calorie contribution and premium serving cost make it poorly suited to users seeking extra energy intake.

Who is it for
  • Adults seeking collagen-based beauty support
  • Users who want collagen with ceramides
  • People comfortable with bovine-sourced powder
Best for
  • Skin-structure support
  • Collagen supplementation
  • Beauty-focused nutrition

Pros

  • Provides 13 g bovine collagen peptides
  • Includes ceramides
  • Adds currant fruit extracts
  • Discloses active quantities

Cons

  • Protein listing conflicts with collagen amount
  • Poor fit for weight gain
  • Betaine amount is small
  • Premium serving cost

Warnings

  • Bovine collagen is unsuitable for people avoiding beef-derived ingredients and may not suit those with a beef allergy.
  • Users sensitive to currant or peach-derived ingredients should note the named fruit extracts and ceramides.
  • The conflicting protein and collagen entries should be clarified before relying on the label for protein tracking.

Nutrient quality

74 High impact

Substantial bovine collagen and well-identified supporting actives provide meaningful connective-tissue nutrition. Incomplete protein, a conflicting protein label, and very low calorie delivery weaken weight-gain suitability.

.

Ingredient transparency

76 High impact

Most active amounts and forms are clear, but the stated protein amount conflicts with the collagen amount. Complete directions and flavor-system ingredients are not supplied.

.

Customer satisfaction

71 High impact

The supplied average is very strong, and the rating count is large. Specific firsthand feedback is absent, so recurring complaints and purpose fit cannot be assessed.

.

Value for money

52 Moderate impact

The premium serving cost is hard to justify for weight gain because the formula supplies little energy and incomplete protein. Useful collagen and skin-focused extras do not overcome the poor category fit.

C- Goal FitD+ Strength of SupportD CoverageD+ Formula Quality

Collagen peptides add some protein and modest calories, but the stated protein amount conflicts with the much larger collagen amount. Even if the collagen amount is accurate, collagen is incomplete and not ideal as the main protein for muscle gain.

Betaine is far below a performance dose, while fruit extracts and ceramides do not meaningfully support weight gain. The formula may complement a calorie surplus but cannot replace adequate complete protein and energy intake.

Report overview
Betaine Anhydrous (Trimethylglycine) · 50 mg OverallScore82
A+ Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyD+ Value

Clearly identified trimethylglycine provides the intended anhydrous betaine form. Its amount suits light wellness support but is far below a performance-focused dose. The premium cost reflects collagen, a nicotinamide riboside precursor, fruit extracts, and ceramides more than betaine.

View ingredientView products
Niacin · 125 mg OverallScore66
B+ Active Ingredient Quality & BioavailabilityB- Dose, Safety & Label TransparencyF Value

Nicotinamide riboside is a direct NAD+ precursor with clear relevance to cellular energy goals. The 125 mg amount is below the preferred research-aligned range, and no stabilized or enteric delivery is disclosed. The serving cost is very high for the amount of nicotinamide riboside provided.

71 Performance

Collagen Fit

Thorne
<p>More collagen peptides and clearly stated protein make this the closest match for the original product's connective-tissue and protein purpose. Calories remain modest and collagen is incomplete protein, so it still has limited use for weight gain.</p>
83 Performance

Betaine Anhydrous

NutraBio
<p>A clearly identified gram of trimethylglycine provides far more betaine and aligns better with the configured weight-gain goal than the original token amount. It supplies no collagen, complete protein, or calorie surplus, so it remains an adjunct rather than a weight-gain food.</p>
77 Performance

Tru Niagen Unflavored

ChromaDex
<p>A clearly named nicotinamide riboside chloride formula provides more of the original product's cellular-energy ingredient in a simple active blend. It supplies no collagen, complete protein, betaine, or meaningful calories and therefore remains poorly aligned with weight gain.</p>
80 Budget

Niacinamide 500 mg

Best Naturals
<p>A very low serving cost provides clearly identified niacinamide for NAD metabolism and skin-related use. It does not supply collagen, protein, or enough calories for weight gain, and its high amount is above basic nutritional needs.</p>
82 Budget

Sustained-Release Niacin with niaXtend 500 mg

Doctor's Best
<p>A far lower serving cost provides a clearly identified vitamin B3 form with more direct cardiovascular relevance. It lacks collagen and calories for weight gain, while high-dose niacin still carries flushing and liver-related concerns.</p>
82 Budget

Niacinamide 500 mg

NOW
<p>Simple niacinamide offers skin-oriented vitamin B3 support at a much lower serving cost. It cannot replace the original collagen peptides or contribute meaningful calories, and the high amount is not suited to casual long-term use.</p>
72 Value

NiaCel 400

Thorne
<p>Higher nicotinamide riboside and betaine amounts come at a lower serving cost in a compact formula. It omits collagen and calories, so the value applies to the cellular-energy ingredients rather than the configured weight-gain goal.</p>
81 Value

NAD+ Cell Regenerator

Life Extension
<p>A meaningful branded nicotinamide-riboside amount lowers serving cost while concentrating on one of the original product's supporting ingredients. It provides neither collagen nor betaine and cannot replace complete protein or a calorie surplus.</p>
80 Value

No-Flush Niacin (Inositol Hexanicotinate) 500 mg

Solgar
<p>A much lower serving cost offers clearly named no-flush niacin for users who only want vitamin B3 support. The formula has no collagen, protein, betaine, or meaningful calories, so it is not a direct weight-gain replacement.</p>
