Nickel + Vitamin E — Supplement Stacking Guide
Found together in 2 real supplement products in our database
What Each Ingredient Does
Our database of real supplement products shows that Nickel and Vitamin E appear together in 2 products, making this one of the more common pairings among supplement formulators. The evidence and dosing guidance below apply to each ingredient independently.
Nickel
Preferred form: Nickel (S4 bioavailability)
Vitamin E
Preferred form: Vitamin E (as Mixed Tocopherols) (S1 bioavailability)
May support: cellular protection against oxidative stress, cardiovascular health and healthy lipid metabolism, skin health and UV resilience.
In six healthy adults (three men, three women, aged 25–59), deuterium-labelled natural (RRR-) and synthetic (all-rac-) alpha-tocopheryl acetate were given together — 150 mg of each daily for 11 consecutive days — so the two forms could be distinguished in plasma by mass spectrometry. Relative bioavailability of the natural form compared with the synthetic form was 2.0 ± 0.06 by area under the plasma concentration-time curve (P < 0.05). The authors concluded that this ratio is significantly greater than the 1.36 ratio accepted at the time. This was a small study using simultaneous co-ingestion of both forms, a design that later work suggests can widen the apparent difference. PubMed

Frequently Asked Questions
What is the best form of Nickel?
Nickel is the Customer Choice form of Nickel in the FormulaForge formulary, reflecting research-backed evidence for superior bioavailability (low). This classification is based on published absorption studies and peer-reviewed bioavailability data. The best form for you depends on your individual health goals and your healthcare provider's recommendations. Always consult a qualified healthcare provider before starting, stopping, or adjusting any supplement regimen.
What is the best form of Vitamin E?
Vitamin E (as Mixed Tocopherols) is the Preferred Form form of Vitamin E in the FormulaForge formulary, reflecting research-backed evidence for superior bioavailability (high). This classification is based on published absorption studies and peer-reviewed bioavailability data. The best form for you depends on your individual health goals and your healthcare provider's recommendations. Always consult a qualified healthcare provider before starting, stopping, or adjusting any supplement regimen.
What are the benefits of Vitamin E?
Vitamin E has been studied for its role in supporting: Supports cellular protection against oxidative stress, Supports cardiovascular health and healthy lipid metabolism, Supports skin health and UV resilience, Supports immune system function, Supports neurological health and cognitive function. Mixed tocopherols provide alpha-, beta-, delta-, and gamma-tocopherol — the full spectrum naturally found in food. Gamma-tocopherol, the predominant dietary form, is severely depleted by alpha-tocopherol-only supplements but is preserved and elevated (4-fold increase) with mixed tocopherol formulations. Natural RRR-alpha-tocopherol carries 1.36x biopotency compared to synthetic all-rac-alpha-tocopherol. Mixed tocopherol preparations uniquely deliver gamma-tocopherol's anti-inflammatory activity, including measured reduction of leukotriene B4 production in double-blind trials. These statements are based on structure/function research and have not been evaluated by the Food and Drug Administration.

Can you take Nickel and Vitamin E at the same time?
Nickel and Vitamin E appear together in 2 products in our database of real supplement formulas. That reflects a common formulator pairing — it is not, by itself, evidence that combining them produces an additive or synergistic effect beyond what each ingredient contributes independently. As with any supplement regimen, consult a qualified healthcare provider to confirm the combination is appropriate for your individual health needs.

- In six healthy adults (three men, three women, aged 25–59), deuterium-labelled natural (RRR-) and synthetic (all-rac-) alpha-tocopheryl acetate were given together — 150 mg of each daily for 11 consecutive days — so the two forms could be distinguished in plasma by mass spectrometry. Relative bioavailability of the natural form compared with the synthetic form was 2.0 ± 0.06 by area under the plasma concentration-time curve (P < 0.05).

- A randomised crossover trial in ten healthy men carrying the apolipoprotein E4 genotype compared deuterium-labelled natural (RRR-) and synthetic (all-rac-) alpha-tocopherol given separately rather than together — a "noncompetitive" design — before and after two 4-week supplementation periods of 400 mg/day, with a 12-week washout. The natural-to-synthetic ratio was 1.35:1 ± 0.17 by peak plasma concentration and 1.33:1 ± 0.18 by area under the curve, close to the long-accepted biopotency ratio of 1.36:1 and lower than the roughly 2:1 ratios reported in earlier studies that gave both forms at the same time. Findings come from a small, all-male, single-genotype sample and may not generalise. PubMed
- A randomized controlled trial reported that tocotrienol supplementation supports the body's normal antioxidant defense activity in older adults. PubMed
- A systematic review found tocotrienols are orally absorbed in humans with delta and gamma isomers among the better-absorbed forms. PubMed
- Research suggests delta-tocotrienol is well absorbed when taken orally. In a study of 36 healthy adults, oral delta-tocotrienol significantly raised plasma tocotrienol levels and was well tolerated. PubMed
- Tocotrienol plasma exposure increased with higher oral doses in healthy fed humans. PubMed
- Double-blind RCT, 55 type 2 diabetes subjects: mixed tocopherols significantly reduced neutrophil leukotriene B4 (P=0.02) while alpha-tocopherol alone did not (P=0.15); neutrophil gamma-tocopherol increased with mixed supplementation but decreased with alpha-alone (P<0.005); demonstrates gamma-tocopherol-dependent anti-inflammatory benefit unique to mixed tocopherol formulation PubMed
- RCT, 58 subjects, 6 weeks: 500mg/day mixed tocopherols (60% gamma) caused 4-fold increase in serum and cellular gamma-tocopherol (P<0.001); alpha-tocopherol alone significantly decreased RBC gamma-tocopherol; demonstrates mixed tocopherols uniquely preserve the gamma-tocopherol pool unavailable with alpha-tocopherol-only supplements PubMed
- Randomized comparison of 4 vitamin E formulations (800 IU/day, 10 days) in normal male subjects: RRR-alpha-tocopherol (natural) has 1.36x biopotency vs all-rac (synthetic); bioavailability of alpha-tocopherol not affected by co-presence of other tocopherols in mixed formulations; all groups significantly suppressed serum gamma-tocopherol vs baseline PubMed
